DC 8210 · 38 CFR 4.124a
Tenth (Pneumogastric/Vagus) Cranial Nerve, Paralysis of C&P Exam Prep
To document the nature, severity, and functional impact of vagus (tenth cranial nerve) paralysis, including its effects on voice, swallowing, respiration, cardiovascular function, gastrointestinal function, and salivation, in order to assign an accurate disability rating under 38 CFR 4.124a DC 8210.
- Format:
- Interview + Physical
- Typical duration:
- 30-45 minutes
- DBQ form:
- Cranial_Nerve_Conditions (Cranial_Nerve_Conditions)
- Examiner:
- Neurologist or Physician
What the examiner evaluates
- Degree of paralysis: complete vs. incomplete (moderate or severe)
- Voice quality, hoarseness, aphonia, or dysphonia
- Swallowing function and presence of dysphagia
- Respiratory function and any breathing difficulties
- Heart rate regulation and cardiac autonomic function
- Gastrointestinal symptoms including nausea, vomiting, gastric motility issues
- Salivary secretion abnormalities (increased or decreased salivation)
- Pharyngeal function and gag reflex integrity
- Soft palate movement and uvular deviation
- Sensory deficits in pharynx, larynx, and external ear canal
- Pain characterization: constant, intermittent, or dull
- Paresthesias or dysesthesias in nerve distribution
- Other cranial nerves potentially involved (IX, XI, XII)
- Functional impact on occupational and daily activities
- Consistency of symptoms with objective neurological findings
Exam will include both a detailed history interview and a neurological physical examination. The examiner will perform cranial nerve testing including assessment of gag reflex, soft palate elevation, vocal cord function (possibly indirect laryngoscopy), and autonomic signs. Bring all relevant medical records, imaging, and specialist notes. The examiner completes the Cranial Nerves Conditions DBQ and may reference diagnostic studies such as EMG, laryngoscopy reports, modified barium swallow studies, or MRI findings.
Measurements and tests
Gag Reflex Assessment
What it measures: Integrity of the afferent (CN IX) and efferent (CN X) limb of the gag reflex, indicating degree of pharyngeal motor and sensory involvement of the vagus nerve.
What to expect: Examiner touches the posterior pharyngeal wall with a tongue depressor. Absent or diminished gag reflex on one or both sides will be documented. This is a key objective finding supporting incomplete or complete paralysis.
Critical thresholds
- Absent bilaterally Supports complete or severe incomplete paralysis; significant contribution toward 30-50% rating
- Absent unilaterally Supports incomplete paralysis, moderate to severe; 10-30% range
- Diminished Supports mild to moderate incomplete paralysis; 10% range
Tips
- Report any history of aspiration episodes as these correlate with absent gag reflex
- Note if you have had pneumonia related to aspiration - this is significant functional evidence
- Tell the examiner if you avoid certain food textures or consistencies due to choking risk
Pain considerations: Pharyngeal pain or discomfort with swallowing should be reported before testing begins as it is a separate symptom category on the DBQ.
Soft Palate and Uvular Deviation Observation
What it measures: Motor function of the vagus nerve to the palate. Unilateral vagal palsy causes the uvula to deviate away from the affected side and the soft palate to droop on the paralyzed side.
What to expect: Examiner will ask you to say 'Ahh' and will observe palate elevation and uvular position. This is a direct indicator of motor completeness of vagal paralysis.
Critical thresholds
- No movement of soft palate on affected side with uvular deviation Objective evidence of motor paralysis; supports moderate to complete rating levels
- Partial or asymmetric elevation Incomplete paralysis, severity depends on degree of movement loss
Tips
- Report whether swallowing liquids causes nasal regurgitation - this indicates palate incompetence
- Mention if your voice sounds nasal or hypernasal, which correlates with palatal weakness
Pain considerations: Not primarily a pain-generating test, but report any pain on phonation or swallowing that is ongoing.
Vocal Cord Function and Voice Assessment
What it measures: Recurrent laryngeal nerve branch of CN X motor function. Paralysis causes hoarseness, breathy voice, or aphonia. Bilateral involvement may cause stridor and respiratory compromise.
What to expect: Examiner will listen to your voice quality and may review prior laryngoscopy reports. Describe your voice on your worst day. If you have had ENT evaluations with laryngoscopy documenting cord paralysis, bring those reports.
Critical thresholds
- Complete aphonia or bilateral cord paralysis with respiratory compromise Strongest support for complete paralysis at 50%
- Unilateral cord paralysis with significant dysphonia Supports severe incomplete paralysis at 30%
- Mild hoarseness with functional voice Supports moderate incomplete paralysis at 10%
Tips
- Describe voice changes over the course of a day - many veterans note worsening with fatigue
- Report whether you have had to change careers or limit communication-dependent activities
- Note if your voice fails during extended speaking, singing, or shouting
Pain considerations: Report any pain, tightness, or discomfort in the throat or larynx associated with speaking or swallowing.
Swallowing Function Evaluation
What it measures: Pharyngeal and esophageal motor function dependent on CN X. Dysphagia can indicate incomplete or complete paralysis affecting the organs of the pharynx and esophagus.
What to expect: Examiner will ask detailed questions about swallowing difficulty. Reference any prior modified barium swallow studies, videofluoroscopy, or esophageal manometry. The DBQ has a specific checkbox for difficulty swallowing with severity indication.
Critical thresholds
- Complete dysphagia requiring tube feeding or modified diet Supports complete or severe incomplete paralysis
- Significant dysphagia with frequent choking, aspiration Supports severe incomplete paralysis at 30%
- Mild to moderate dysphagia with dietary modifications Supports moderate incomplete paralysis at 10%
Tips
- Report the specific food consistencies that cause problems (solids, liquids, pills)
- Describe any episodes of food or liquid going into airway (aspiration)
- Note if you have lost weight due to eating difficulties or dietary restrictions
Pain considerations: Odynophagia (painful swallowing) is a distinct symptom from dysphagia - report both if present, with severity and frequency.
Heart Rate and Cardiovascular Autonomic Assessment
What it measures: Vagal parasympathetic control of heart rate. Vagal paralysis can cause tachycardia or abnormal heart rate variability. The rating note under DC 8210 explicitly includes heart as an organ of function.
What to expect: Examiner may check resting pulse rate and note any documented cardiac autonomic abnormalities. Review any cardiology records showing tachycardia, palpitations, or autonomic dysregulation attributed to vagal dysfunction.
Critical thresholds
- Persistent tachycardia with documented autonomic etiology Supports more severe rating; contributes to complete or severe incomplete classification
- Episodic palpitations or heart rate irregularity Supports incomplete paralysis with autonomic involvement
Tips
- Bring any cardiology records or Holter monitor results attributing cardiac symptoms to vagal dysfunction
- Report frequency, duration, and any triggers of palpitations or racing heart
- Note if symptoms affect your ability to exercise or perform physical work
Pain considerations: Chest discomfort associated with palpitations should be reported and distinguished from cardiac pain.
Gastrointestinal Motility and Function Assessment
What it measures: Vagal control of gastric secretion and motility. Impairment can cause gastroparesis, nausea, vomiting, or altered gastric acid secretion. DC 8210 rating note explicitly includes stomach as an organ of function.
What to expect: Examiner will ask about GI symptoms. The DBQ has a specific checkbox for gastrointestinal symptoms with severity. Reference any gastroenterology records, gastric emptying studies, or GI motility testing.
Critical thresholds
- Gastroparesis documented by gastric emptying study Objective evidence supporting severe or complete paralysis rating
- Chronic nausea and vomiting impacting nutrition Supports severe incomplete paralysis at 30%
- Intermittent nausea or early satiety Supports moderate incomplete paralysis at 10%
Tips
- Report frequency of nausea episodes, vomiting, bloating, and early satiety
- Describe any weight loss, nutritional supplements, or dietary adjustments
- Bring gastroenterology notes if gastroparesis has been formally diagnosed
Pain considerations: Abdominal pain related to GI dysmotility should be described with location, character, frequency, and severity.
Salivation Assessment
What it measures: Parasympathetic salivary gland function mediated partly through vagal pathways. Both increased salivation (sialorrhea) and decreased salivation (xerostomia) are DBQ-specific checkbox items.
What to expect: Examiner will ask about drooling, dry mouth, or excessive saliva. The DBQ contains specific fields for both increased and decreased salivation with severity indicators.
Critical thresholds
- Severe sialorrhea requiring constant management Contributes to overall severity assessment for incomplete paralysis
- Significant xerostomia affecting eating and speaking Contributes to functional impairment documentation
Tips
- Report if you drool involuntarily, especially at night or during meals
- Describe any need for suction devices or frequent swallowing to manage saliva
- Note dental problems caused by dry mouth as a functional consequence
Pain considerations: Mouth or throat dryness causing discomfort or cracking should be reported.
Respiratory Function Assessment
What it measures: Vagal contribution to respiratory control and laryngeal airway protection. Bilateral vagal paralysis can cause respiratory compromise. DC 8210 rating note explicitly includes respiration as an organ of function.
What to expect: Examiner will note any reported breathing difficulties, stridor, or shortness of breath. Reference any pulmonology records, pulmonary function tests, or sleep study results related to vagal dysfunction.
Critical thresholds
- Respiratory compromise requiring intervention or supplemental oxygen Supports complete or severe incomplete paralysis at 30-50%
- Exertional dyspnea related to laryngeal incompetence Supports severe incomplete paralysis
- Intermittent stridor or choking episodes Supports moderate to severe incomplete paralysis
Tips
- Report any episodes of stridor, choking, or acute breathing difficulty
- Note if you have been evaluated for sleep apnea as vagal dysfunction can contribute
- Describe any limitations in physical activity due to breathing symptoms
Pain considerations: Chest tightness or pain associated with breathing difficulties should be distinguished from cardiac symptoms and reported to the examiner.
Rating criteria by percentage
50%
Complete paralysis of the tenth cranial nerve. Total loss of function to organs of voice, respiration, pharynx, stomach, and heart dependent upon extent of sensory and motor loss across all innervated structures.
Key symptoms
- Complete aphonia or bilateral vocal cord paralysis
- Severe dysphagia with aspiration or need for alternative feeding
- Significant respiratory compromise related to laryngeal incompetence
- Persistent tachycardia from loss of vagal cardiac parasympathetic control
- Gastroparesis with documented gastric dysmotility
- Complete absence of gag reflex bilaterally
- Complete loss of soft palate elevation
- Severe autonomic dysfunction across multiple organ systems
From 38 CFR: 38 CFR 4.124a DC 8210: 'Complete - 50'. Note states evaluation is dependent upon extent of sensory and motor loss to organs of voice, respiration, pharynx, stomach and heart. Complete paralysis implies total or near-total loss of function across these organ systems.
30%
Incomplete, severe paralysis of the tenth cranial nerve. Significantly impaired function across one or more innervated organ systems with objective neurological findings but less than complete loss.
Key symptoms
- Severe dysphonia with significantly breathy or weak voice
- Marked dysphagia with dietary restrictions and aspiration risk
- Resting tachycardia attributed to reduced vagal tone
- Frequent nausea or documented gastric dysmotility
- Absent gag reflex on affected side
- Significant soft palate droop with uvular deviation
- Chronic cough from laryngeal incompetence or silent aspiration
- Severe sialorrhea or xerostomia impacting daily function
From 38 CFR: 38 CFR 4.124a DC 8210: 'Incomplete, severe - 30'. Per M21-1 guidance, severe incomplete paralysis reflects substantial functional loss across nerve-dependent organ systems. Rating is based on total evidentiary record, not solely examiner's characterization.
10%
Incomplete, moderate paralysis of the tenth cranial nerve. Definite but limited functional impairment in one or more innervated organ systems. This is the minimum compensable rating and requires more than minimal symptoms sufficient to establish the diagnosis.
Key symptoms
- Mild to moderate hoarseness or voice changes
- Occasional dysphagia, particularly with certain food consistencies
- Mild gastrointestinal symptoms including intermittent nausea or early satiety
- Diminished gag reflex
- Mild tachycardia
- Mild pharyngeal sensory changes
- Intermittent cough related to laryngeal dysfunction
- Mild salivation changes
From 38 CFR: 38 CFR 4.124a DC 8210: 'Incomplete, moderate - 10'. Per M21-1 V.iii.12.A.2.c, moderate is the maximum evaluation for purely sensory impairment. Motor findings elevate the rating. The rating note confirms evaluation depends on extent of sensory and motor loss to organs of voice, respiration, pharynx, stomach, and heart.
Describing your symptoms accurately
Voice and Speech Difficulties
How to describe it: Describe the specific quality of your voice change - whether it is hoarse, breathy, weak, strained, or absent. Indicate whether it fluctuates throughout the day, worsens with prolonged use, or is constant. Quantify how long you can speak before your voice gives out. Describe impact on job performance, phone calls, social interactions, or commanding attention in emergencies.
Example: On my worst days, I cannot produce any audible voice above a whisper after about five minutes of speaking. People cannot hear me on the phone and I have had to stop attending meetings at work because I cannot project my voice. I feel constant strain in my throat when I try to talk loudly.
Examiner listens for: Objective dysphonia during the interview, vocal fatigue, aphonia, pitch breaks, nasal resonance, or strained phonation quality that correlates with documented laryngeal or palatal findings.
Avoid: Do not say 'my voice is a little off' if you mean you have persistent hoarseness that affects your daily communication. Do not minimize by saying 'I just sound raspy sometimes' if your voice fails multiple times per day.
Swallowing Difficulty (Dysphagia)
How to describe it: Specify whether difficulty is with solids, liquids, both, or pills specifically. Describe whether food gets stuck, goes down the wrong way, or causes coughing or choking. Report any episodes of aspiration pneumonia. Describe how long meals take and any dietary changes you have made as a result.
Example: On bad days, I choke on liquids and have to thicken everything I drink. Meals take over 45 minutes because I have to eat slowly and carefully. I have been to the emergency room twice for food lodged in my throat, and my doctor told me I had aspiration pneumonia last year.
Examiner listens for: Specific food consistency triggers, frequency of aspiration or choking, documented aspiration pneumonia, weight loss due to dietary restriction, and correlating findings on modified barium swallow or videofluoroscopy studies.
Avoid: Do not say 'I have a little trouble swallowing sometimes' if you choke regularly or have changed your diet. Do not omit episodes of aspiration or pneumonia, which are critical functional indicators.
Gastrointestinal Symptoms
How to describe it: Describe nausea frequency (daily, weekly), severity (scale of 1-10), association with meals, and any vomiting. Report early satiety, bloating, or abdominal discomfort. Note any weight loss and connect it to the GI symptoms. Bring documentation of any gastric emptying studies or gastroenterology evaluations.
Example: I feel nauseated after almost every meal, and some days I vomit two or three times. I can only eat small amounts because I feel completely full after just a few bites. I have lost 20 pounds over the past year because eating makes me feel so sick.
Examiner listens for: Frequency and severity of nausea and vomiting, correlation with meals, documented gastroparesis on objective testing, weight loss trend, and connection to vagal autonomic dysfunction rather than other GI causes.
Avoid: Do not describe GI symptoms as an unrelated complaint. Connect them explicitly to the nerve condition. Do not underreport weight loss, as this is objective evidence of functional impact.
Cardiac Autonomic Symptoms
How to describe it: Describe resting heart rate if elevated, frequency and duration of palpitation episodes, any triggers, and whether this has been evaluated by cardiology. Note if cardiologists have attributed tachycardia to autonomic dysregulation rather than primary cardiac disease.
Example: My resting heart rate is often around 105-110 even when I am sitting quietly. I have constant palpitations that make it difficult to sleep, and my cardiologist confirmed there is no structural heart disease - the tachycardia is from my nerve condition.
Examiner listens for: Objective tachycardia on examination, cardiology records attributing symptoms to vagal dysfunction, heart rate variability studies, and the absence of alternative cardiac explanations for the symptoms.
Avoid: Do not fail to mention cardiac symptoms simply because you have seen a cardiologist. The vagal connection to cardiac function is explicitly recognized in the DC 8210 rating note and must be documented.
Respiratory Symptoms
How to describe it: Describe any shortness of breath, stridor, choking episodes, or chronic cough. Note whether symptoms occur at rest or with exertion. Report any sleep-disordered breathing attributed to laryngeal incompetence. Describe limitations on physical activity caused by breathing symptoms.
Example: I have a constant chronic cough that worsens when I lie down, and I have episodes of stridor at night that wake me and my spouse. I cannot exercise the way I used to because I start choking and feel like I cannot get enough air through my throat.
Examiner listens for: Audible stridor, chronic cough correlated with laryngeal dysfunction, pulmonary function test results, sleep study findings, and limitations in exertional capacity attributable to laryngeal incompetence rather than pulmonary disease.
Avoid: Do not attribute breathing symptoms only to a separate respiratory condition if your treating physicians have connected them to the vagal nerve impairment. Bring any ENT or pulmonology records that make this connection.
Salivation Abnormalities
How to describe it: Clearly state whether you have excessive drooling (sialorrhea) or dry mouth (xerostomia), as these are separate DBQ checkbox items. Describe frequency and severity. For sialorrhea, report whether it is constant or positional. For xerostomia, describe impact on eating, speaking, and dental health.
Example: I constantly have excess saliva pooling in my mouth and drooling involuntarily, especially when I am concentrating or lying down. I have to carry a cloth with me at all times and it is extremely embarrassing in social and work settings.
Examiner listens for: Clinical observation of salivary pooling or dry mucous membranes, patient description of severity and functional impact, and correlation with the vagal parasympathetic innervation of salivary glands.
Avoid: Do not dismiss salivation changes as trivial. Both increased and decreased salivation have dedicated DBQ fields precisely because they represent documentable autonomic dysfunction supporting the diagnosis and severity rating.
Pain Characterization
How to describe it: The DBQ includes checkboxes for constant pain (at times excruciating), intermittent pain, and dull pain, each with location and severity fields. Describe your pain using all three dimensions: character (burning, aching, stabbing), location (ear canal, throat, pharynx), and severity on a 1-10 scale. Distinguish pain from other symptoms.
Example: I have constant burning pain in my throat and deep in my ear canal that I rate as 8 out of 10 on bad days. Even when it is less severe, it is always present as a dull ache of about 4 out of 10. The pain makes it hard to concentrate at work and interferes with sleep.
Examiner listens for: Specific pain location within the vagal nerve distribution (pharynx, larynx, external ear canal, thorax, abdomen), pain character, consistency, severity, and how it differs from baseline. Pain in the external ear canal (Arnold's nerve) is a classic vagal distribution finding.
Avoid: Do not describe pain only as 'discomfort.' Use specific pain severity ratings. Do not omit ear canal pain, which is a recognized vagal nerve distribution symptom that may not be intuitive to connect to this condition.
Functional Impact on Daily Life and Work
How to describe it: Describe specific activities you cannot do or have had to modify due to the condition. Include work limitations, social restrictions, dietary changes, use of assistive devices, and any accommodations you have requested. This is the functional impact section of the DBQ and is critical to the rating.
Example: I had to leave my job as a teacher because I could not project my voice or manage a classroom. I cannot attend social events because eating and speaking in public is too unpredictable. I choke, drool, and my voice fails at the worst moments. I have had to install special equipment in my home and I require help preparing meals with modified textures.
Examiner listens for: Specific, concrete examples of occupational and social functional loss that directly correlate with the documented nerve impairment. The examiner must document functional impact on the DBQ, and specific examples provide the most compelling evidence.
Avoid: Do not say 'it affects my life' without specific examples. Do not understate occupational impact. Do not fail to mention assistive devices, dietary supplements, or medical equipment used to manage the condition.
Common mistakes to avoid
Describing symptoms only on the day of the exam rather than on worst days
Why: The C&P exam captures a single point in time, but VA rating is based on the average functional impact including worst manifestations. An unusually good day at the exam can result in an artificially low rating.
Do this instead: Explicitly state 'on my worst days' when describing symptoms. Bring a symptom diary documenting frequency and severity over the prior 30-90 days. State that today may not represent your typical or worst functioning.
Impact: Can cause underrating from 30% to 10% or from 50% to 30%
Failing to connect all organ system symptoms to the vagus nerve
Why: The DC 8210 rating note explicitly covers voice, respiration, pharynx, stomach, and heart. Veterans who have GI symptoms, cardiac symptoms, and respiratory symptoms from vagal dysfunction often present these as unrelated complaints to different specialists without connecting them to the rated nerve condition.
Do this instead: Before the exam, compile records from every treating specialist (ENT, gastroenterology, cardiology, pulmonology) and explicitly connect their findings to vagal nerve dysfunction. Prepare a written summary connecting each organ system symptom to this rated condition.
Impact: Can cause severe underrating - complete paralysis rated as moderate (10%) if organ system symptoms are not attributed to the nerve condition
Minimizing symptoms out of stoicism or reluctance to 'complain'
Why: The DBQ has specific checkboxes for every symptom category. If you minimize, the examiner marks fewer checkboxes, and the rating is driven by what is documented, not what you actually experience.
Do this instead: Provide accurate, complete descriptions of all symptoms without minimizing. Use concrete language and severity scales. Accuracy is not complaining - it is ensuring the record reflects your actual medical condition.
Impact: Can affect any rating level - most commonly causes 30% cases to be rated at 10%
Not bringing objective diagnostic test results to the exam
Why: Laryngoscopy reports, modified barium swallow studies, gastric emptying studies, Holter monitor results, and EMG reports provide objective evidence of functional loss. Without them, the examiner relies solely on clinical findings on that day.
Do this instead: Gather all specialist records, imaging reports, and diagnostic study results that document vagal nerve dysfunction. Organize them chronologically and highlight the most relevant findings. Bring copies to give the examiner if they do not have them.
Impact: Most critical for distinguishing 30% from 50% and for supporting 30% over 10%
Failing to report the impact of the condition on the other cranial nerves evaluated on the same DBQ
Why: The Cranial Nerves DBQ covers all 12 cranial nerves. Co-existing involvement of adjacent nerves (CN IX glossopharyngeal, CN XI spinal accessory, CN XII hypoglossal) which may share anatomic proximity to the vagus, can provide additional evidence of the extent of the neurological insult.
Do this instead: Report any symptoms that might involve adjacent cranial nerves - difficulty with tongue movement (CN XII), shoulder weakness (CN XI), or bitter/sour taste sensation changes (CN IX) - so the examiner can evaluate and document them appropriately.
Impact: Affects completeness of documentation; may affect combined rating calculations
Not quantifying functional limitations with specific numbers and timeframes
Why: Vague descriptions like 'I have trouble swallowing sometimes' are documented as mild. Specific descriptions like 'I choke on liquids three to four times daily and have modified my diet to all pureed foods for the past six months' create a clear, documentable picture of severity.
Do this instead: Prepare specific quantified statements for each symptom: frequency per day or week, duration of episodes, severity on a 1-10 scale, and specific functional activities affected. Write these down and refer to your notes during the exam.
Impact: Critical at all levels - determines whether symptoms are rated as moderate (10%) vs. severe incomplete (30%) vs. complete (50%)
Not mentioning that symptoms worsen with activity, fatigue, or stress
Why: Vagal symptoms often fluctuate. A veteran who appears relatively stable at rest during a morning exam may be significantly disabled by afternoon fatigue. Without documenting this pattern, the examiner records a falsely stable picture.
Do this instead: Explicitly describe how symptoms change throughout the day, with prolonged use (voice), after meals (GI), with exertion (respiratory, cardiac), or under stress. This reflects the true disability picture.
Impact: Most impactful at the 10% to 30% threshold
Overlooking the ear canal as a pain location for vagal nerve distribution symptoms
Why: The vagus nerve supplies sensation to the posterior external ear canal (Arnold's nerve). Pain in this area is a classic vagal distribution symptom that veterans may not connect to their nerve condition, and examiners may not ask about it directly.
Do this instead: Specifically mention any deep ear canal pain, even if it seems unrelated to your throat or voice symptoms. Describe it as located in the deep part of the ear canal, and note that it may worsen with swallowing or speaking.
Impact: Contributes to completeness of documentation - supports diagnosis and severity of neuralgia or paralysis
Prep checklist
- critical
Compile complete medical records for all organ systems affected by vagal dysfunction
Gather ENT/laryngology records with laryngoscopy reports, gastroenterology records including gastric emptying studies, cardiology records including Holter monitors and echocardiograms, pulmonology records and pulmonary function tests, any swallowing studies (modified barium swallow, videofluoroscopy, esophageal manometry), MRI or CT of brain/skull base/neck if applicable, and neurology records. Organize chronologically and tab the most relevant findings.
before exam
- critical
Write a detailed symptom narrative covering all vagal-innervated organ systems
Write a one to two page narrative describing your voice symptoms, swallowing difficulties, GI symptoms, cardiac symptoms, respiratory symptoms, and salivation changes. Include onset, progression, worst-day descriptions, frequency, severity ratings, and functional impact for each organ system. Review this before the exam and bring it with you.
before exam
- critical
Keep a symptom diary for at least two weeks before the exam
Record daily: voice quality and duration of use before failure, any choking or aspiration episodes, GI symptoms including nausea, vomiting, and bloating, heart rate if measurable, respiratory symptoms, and salivation issues. This diary provides objective documentation of symptom frequency and severity over time.

- recommended
Research your rights regarding exam recording in your state
Many states permit veterans to audio or video record their C&P examination. Check whether your state is a one-party or two-party consent state for recording. Notify the examiner at the start of the exam if you intend to record. Recording creates an accurate record if the DBQ documentation does not match what was discussed.
before exam
- critical
Prepare a concise list of all current medications related to the condition
Include medications for voice (e.g., proton pump inhibitors for laryngopharyngeal reflux), GI motility agents (e.g., metoclopramide for gastroparesis), cardiac medications for tachycardia, and any anti-nausea medications. The use of these medications is itself evidence of severity and organ system involvement.
before exam
- critical
Identify and document occupational and daily living functional impacts
Write specific examples of work duties you cannot perform, social activities you have stopped or modified, dietary changes and special foods or equipment required, and any assistive devices used. Include any ADA accommodations requested at work or any changes in employment status related to the condition.
before exam
- recommended
Review the DC 8210 rating criteria and understand the organ system note
The rating note under DC 8210 specifies that the rating is dependent upon the extent of sensory and motor loss to organs of voice, respiration, pharynx, stomach, and heart. Ensure you can speak to each of these organ systems specifically during the exam.
before exam
- recommended
Do not take medications that mask or reduce symptoms before the exam unless medically necessary
If you take medications that reduce nausea, tachycardia, or voice symptoms, note this to the examiner so the documented findings reflect medicated rather than unmedicated baseline. Inform the examiner what your condition is like without medication. Consult your treating physician before altering any medication regimen.

- recommended
Dress and behave consistently with your actual functional status
If you use a voice amplifier, bring it but explain why you need it. If certain foods are off-limits, do not eat them the morning of the exam only to feel better during testing. Present your honest, typical functional status - not a performance of health or disability.
day of
- optional
Bring a support person or veterans service organization representative if permitted
A VSO representative or trusted support person can help ensure the exam stays on track, document what was asked and answered, and help you remember to mention key symptoms if you become anxious. Check VA facility policy on support persons for C&P exams.

Report symptoms across all five organ systems explicitly mentioned in the DC 8210 rating note
Before leaving the exam, ensure you have described symptoms related to: (1) voice, (2) respiration, (3) pharynx/swallowing, (4) stomach/GI, and (5) heart/cardiac autonomic function. Do not assume the examiner will ask about each category. Volunteer the information if not asked.
during exam
- critical
Describe your worst-day experience, not your best-day or average-day experience
Per M21-1 guidance, describe the worst manifestation of your symptoms when asked how you are doing. Use phrases such as 'on my worst days' or 'at its worst.' Then provide frequency context: 'this happens about three times per week.'

Correct any misstatements or omissions before the exam ends
If the examiner appears to be summarizing your condition in a way that understates your symptoms, politely correct the record before the exam concludes. Ask if there is anything else they need to know about how the condition affects your daily life. You have the right to ensure the record is accurate and complete.
during exam
- recommended
Request copies of the DBQ and the examiner's findings after the exam
Ask the examiner or facility staff how to obtain a copy of the completed DBQ. You are entitled to a copy of your examination report. Review it for accuracy and contact your VSO or VA regional office promptly if there are significant errors or omissions.
during exam
- recommended
File a written buddy statement if you were unable to fully communicate your symptoms
If you left the exam feeling important symptoms were not documented, a lay statement (buddy statement) from yourself or a person who witnesses your daily symptoms can be submitted to supplement the record. Submit it to your VA regional office as soon as possible after the exam.
after exam
- critical
Review the completed DBQ for accuracy when it becomes available
Request the DBQ through the VA's Blue Button portal or from your VSO. Verify that all organ systems you described are documented, that severity levels reflect what you reported, and that there are no factual errors. If significant discrepancies exist, discuss options for requesting a supplemental claim or submitting additional evidence with your VSO.
after exam
- recommended
Consult a VSO or accredited VA claims agent if the rating decision does not reflect your documented symptoms
If the rating decision assigns a lower rating than the evidence supports, you have options including a supplemental claim with new evidence, a higher-level review, or an appeal to the Board of Veterans' Appeals. Act within the applicable response periods to preserve your effective date.
after exam
Your rights during a C&P exam
- You have the right to request a copy of the completed Disability Benefits Questionnaire (DBQ) after your examination through the VA Blue Button portal or by requesting it from the examining facility.
- You have the right to submit your own lay statement (buddy statement) describing your symptoms, functional limitations, and daily impact, and this statement is evidence of record that VA must consider.
- You have the right to have a Veterans Service Organization representative, accredited claims agent, or attorney assist you in preparing for and attending your C&P examination.
- You have the right to record your C&P examination in many states where one-party consent recording laws apply. Notify the examiner at the start of the exam if you intend to record. Verify applicable state law before proceeding.
- You have the right to request a new C&P examination if you believe the original examination was inadequate, if the examiner did not examine you in person, or if significant time has passed and your condition has worsened.
- You have the right to submit additional evidence, including private medical opinions and specialist records, at any stage of the claims process to supplement or correct the evidentiary record.
- You have the right to appeal a rating decision through the Supplemental Claim lane (new and relevant evidence), Higher-Level Review lane (de novo review), or the Board of Veterans' Appeals (hearing or record review options) under the Appeals Modernization Act.
- You have the right to a fully explained rating decision that identifies the evidence considered, the rating criteria applied, and the reasons and bases for the rating assigned. If this explanation is inadequate, this may be grounds for appeal.
- You have the right to an examination conducted by a qualified examiner who has reviewed your claims file before examining you. If the examiner has not reviewed your file, document this and report it to your VSO.
- You have the right to a liberal reading of the DC 8210 rating note by the rating activity, which must consider functional loss across all five organ systems (voice, respiration, pharynx, stomach, and heart) when assigning the rating level for vagal nerve paralysis.
Related conditions
- Ninth (Glossopharyngeal) Cranial Nerve, Paralysis of CN IX and CN X share anatomic proximity at the jugular foramen and often are affected together. Both contribute to gag reflex, swallowing, and pharyngeal sensation. Co-existing CN IX involvement is evaluated separately and documented on the same Cranial Nerves DBQ.
- Eleventh (Spinal Accessory) Cranial Nerve, Paralysis of CN XI also exits through the jugular foramen adjacent to CN X. Pathology in this region (tumors, trauma, surgery) can affect both nerves simultaneously. CN XI paralysis is rated separately under DC 8211.
- Tenth (Vagus) Cranial Nerve, Neuralgia of DC 8409 covers neuralgia of the vagus nerve, which may coexist with or evolve from paralysis. Neuralgia involves pain in the nerve distribution without necessarily the same degree of motor loss. Separately ratable if the clinical picture includes both paralysis and neuralgia characteristics.
- Dysphonia and Vocal Cord Paralysis Recurrent laryngeal nerve paralysis, a branch of CN X, causes vocal cord paralysis and dysphonia. ENT or laryngology records documenting vocal cord paralysis by laryngoscopy provide critical objective evidence for DC 8210 rating purposes.
- Gastroparesis Vagal parasympathetic control of gastric motility means vagal paralysis can directly cause gastroparesis. Gastric emptying studies documenting gastroparesis provide objective evidence supporting the GI organ system component of the DC 8210 rating note and may be separately ratable under GI diagnostic codes if sufficiently severe.
- Dysphagia Dysphagia is a direct manifestation of vagal motor paralysis affecting the pharyngeal and esophageal phases of swallowing. Modified barium swallow or videofluoroscopy studies documenting aspiration or pharyngeal dysmotility provide critical objective evidence for DC 8210 severity determination.
- Autonomic Dysregulation / Vagal Tachycardia The cardiac parasympathetic effect of the vagus nerve means vagal paralysis can produce persistent resting tachycardia. Cardiology records attributing tachycardia to autonomic dysfunction rather than primary cardiac disease directly support the cardiac organ system component of the DC 8210 rating note.
