Degenerative Arthritis (Osteoarthritis) C&P Exam Prep

Range of Motion (ROM) Testing - Active

What it measures: The degrees of voluntary joint movement the veteran can produce independently, measured with a goniometer. Per Correia requirements, active ROM must be recorded before passive ROM.

What to expect: Examiner will ask you to move each affected joint through its full range while they measure the angle with a goniometer. They should record the point at which pain begins, not just the endpoint.

Pain considerations: Per DeLuca v. Brown, pain on motion is a separately ratable factor. The examiner must record the angle at which pain begins. If your range appears normal at rest but you experience pain throughout, state this clearly and consistently.

Range of Motion (ROM) Testing - Passive

What it measures: The degrees of joint movement achieved when the examiner moves the joint without your active muscle effort. Per Correia requirements, passive ROM testing is mandatory and must be compared to active ROM.

What to expect: The examiner will gently move your joint for you. This should be done after active ROM. Discrepancy between active and passive ROM helps document true functional limitation.

Pain considerations: Pain during passive ROM also counts toward your overall functional limitation and should be verbally communicated to the examiner in real time.

Range of Motion - Weight-Bearing vs. Non-Weight-Bearing

What it measures: Compares joint ROM in positions that load the joint (standing, walking) versus positions that unload it (lying down, seated). Particularly critical for knee, hip, and ankle arthritis. Per Correia requirements, both positions must be assessed for lower extremity joints.

What to expect: Examiner will test ROM in both standing/walking and seated/lying positions. Differences help document true functional disability.

Pain considerations: Many veterans with knee or hip OA have near-normal sedentary ROM but severe limitations with any weight-bearing activity. Make sure this functional reality is clearly communicated.

Repetitive Use / Fatigability Testing

What it measures: Per DeLuca v. Brown, examiners must assess whether ROM decreases and pain increases after repetitive use. This reflects real-world functional limitation that a single static measurement misses.

What to expect: Examiner may ask you to perform repetitive movements of affected joints (e.g., repeated knee flexion/extension, shoulder rotation). ROM and pain should be re-measured after the repetitions.

Pain considerations: Fatigue is a DeLuca factor that applies to arthritis. If your joints become significantly more painful, weak, or stiff after even moderate activity, this must be communicated and documented.

Radiographic / Imaging Review (X-ray, MRI, CT)

What it measures: Objective evidence of degenerative joint changes including joint space narrowing, osteophyte formation, subchondral sclerosis, and cyst formation. Under DC 5003, X-ray confirmation of arthritis is required for a compensable rating based solely on radiographic findings.

What to expect: Examiner will review existing imaging or may order new X-rays. Imaging findings are recorded in the DBQ under imaging sections. Bring copies of all prior imaging reports and discs.

Pain considerations: Imaging findings alone (without functional limitation) can still yield a 10-20% rating under DC 5003 for major joint involvement. However, combining imaging findings with documented functional limitation and DeLuca factors is how higher ratings are achieved.

Laboratory Testing (Inflammatory Markers, CBC, Serologies)

What it measures: Blood tests including ESR, CRP, CBC, rheumatoid factor, anti-CCP antibodies, ANA, and anti-DNA antibodies help differentiate degenerative osteoarthritis from inflammatory arthritides. Under DC 5003, these are typically normal in pure OA.

What to expect: Examiner will review any available lab results. May order labs if not recently done. Normal inflammatory markers actually support a diagnosis of osteoarthritis rather than rheumatoid or other inflammatory arthritis.

Pain considerations: Lab results are used for diagnostic classification, not for measuring pain or functional limitation. Your self-reported symptoms and functional limitations remain the primary basis for rating severity.

0%

No radiographic evidence of arthritis, OR degenerative changes present but no functional limitation and not meeting criteria for compensable rating under DC 5003 or a specific joint diagnostic code. Note: Many veterans are rated noncompensably (0%) even with confirmed OA if functional limitation is minimal.

From 38 CFR: Under DC 5003, a 0% (noncompensable) rating may apply when arthritis is confirmed radiographically but does not meet the threshold for a 10% rating (fewer than 2 major joints or 2-4 minor joints involved without additional limitation of motion).

10%

Degenerative arthritis established by X-ray findings with occasional incapacitating exacerbations. Under DC 5003, a 10% rating applies when arthritis is confirmed radiographically involving 2 or more major joints or 2-4 minor joint groups, with or without symptoms. Alternatively, limitation of motion of a major joint that is below the compensable threshold under a specific joint DC but still present.

From 38 CFR: Under 38 CFR 4.71a, DC 5003: X-ray evidence of involvement of 2 or more major joints or 2-4 minor joint groups, with or without symptoms = 10%. The key is documenting the radiographic findings across multiple joints even if individual joint ROM is borderline.

20%

Degenerative arthritis with X-ray evidence involving 2 or more major joints or 2-4 minor joint groups with frequent incapacitating exacerbations. Under DC 5003, 20% applies when there are frequent incapacitating exacerbations. Alternatively, if limitation of motion in a specific joint reaches the threshold under a joint-specific DC (e.g., DC 5260/5261 for knee), the higher rating under that code applies and DC 5003 is not used.

From 38 CFR: Under DC 5003: 20% when X-ray confirmed arthritis in 2+ major or 2-4 minor joint groups with frequent incapacitating exacerbations. Note: If limitation of motion in a single joint (e.g., knee flexion to 60-) is separately ratable at 20% or higher under a specific DC, apply that code and do not use DC 5003 for that joint.

40%

This rating level under DC 5003 alone is not standard; however, veterans with OA affecting major joints with severe limitation of motion, ankylosis, or significant functional impairment may reach 40% or higher when rated under joint-specific diagnostic codes (e.g., DC 5252 for hip, DC 5256 for knee ankylosis, DC 5200 for shoulder). DC 5003 establishes the baseline diagnosis; joint-specific codes capture the higher functional impairment.

From 38 CFR: Joint-specific DCs such as DC 5252 (hip, thigh, leg limitation of extension) at 40% for limitation of extension to 20-; DC 5256 (knee, ankylosis) at 40% for ankylosis in a position other than full extension; DC 5200 (shoulder, ankylosis) at 40% for the minor extremity in a favorable position. DC 5003 is used as the foundation diagnosis when joint-specific codes apply at 10-20%, with the higher joint-specific code controlling the rating.

Pain on Motion and at Rest

How to describe it: Describe pain using a 0-10 scale, specify which joints are affected, what movements trigger the pain, how long the pain lasts after activity, and whether pain is present even at rest. Use concrete descriptions: 'My right knee pain is a 7/10 when I walk more than half a block and a 4/10 even at rest at night.'

Example: On my worst days, which happen 3-4 times per month, my knee pain is 9/10 from the moment I wake up. I cannot bend my knee past 45 degrees without severe pain, I need my cane just to get to the bathroom, and I spend most of the day in the recliner with ice. The pain keeps me awake at night.

Examiner listens for: Specific joint locations, pain severity at rest vs. with motion, the degree of motion at which pain begins, whether pain prevents completion of normal daily activities, and whether pain has worsened over time.

Avoid: Do not say 'it's manageable' or 'I get by' - these phrases suggest your symptoms are not severe. Instead, accurately describe what you must give up or modify to manage your pain. Do not describe your best days as your typical days.

Flare-Ups: Incapacitating vs. Non-Incapacitating

How to describe it: Distinguish between non-incapacitating exacerbations (increased pain and limitation but you can still function with difficulty) and incapacitating exacerbations (require bed rest and physician treatment). Document approximate frequency (how many times per month/year), duration (days/weeks), and what triggers them.

Example: I have non-incapacitating flare-ups about 2-3 times per week where my hip pain goes from a baseline 4/10 to 7-8/10, I cannot walk more than 50 feet, and I miss work or cancel plans. About once a month, I have a fully incapacitating flare lasting 3-5 days where I cannot get out of bed without help, I call my doctor, and I take prescription-strength anti-inflammatories and apply ice continuously.

Examiner listens for: Frequency and duration of both types of exacerbations, whether physician treatment was sought, whether the veteran was confined to bed or home, and whether flare-ups cause missed work or inability to perform self-care.

Avoid: Do not minimize flare-ups as 'just bad days.' If you have sought medical care, reduced activity, or been confined to rest, these are incapacitating exacerbations. Ensure the examiner documents both types in the appropriate DBQ fields.

Fatigue, Weakness, and Incoordination (DeLuca Factors)

How to describe it: These are separate ratable factors under DeLuca v. Brown. Describe how your joints fatigue with use - e.g., after walking one flight of stairs, your knees feel weak and unstable. Describe incoordination or instability (joint giving way). Describe muscle weakness from disuse or pain inhibition.

Example: After walking for 10 minutes, my knees feel weak and start to give way without warning. I have fallen twice this year because of this. My hands fatigue quickly when gripping - after opening 3-4 jars or bottles in a row, I lose grip strength entirely and have to stop. This weakness and instability is worse on flare-up days.

Examiner listens for: Whether weakness, fatigue, or incoordination appear or worsen with repetitive use, whether these factors limit occupational activities, whether there have been falls or near-falls, and whether grip strength or ambulation is affected.

Avoid: Do not omit fatigue and weakness just because they seem less dramatic than pain. These are legally required rating factors under DeLuca. If the examiner does not ask about them, volunteer this information: 'I also experience significant joint fatigue and weakness with repetitive use.'

Functional Impact on Daily Activities and Employment

How to describe it: Describe specific activities you can no longer do or can only do with great difficulty: walking distances, climbing stairs, standing from chairs, overhead reaching, gripping, driving, dressing, bathing, shopping, yard work, sleeping. Be specific about distances, time limits, and adaptations.

Example: I can no longer stand at my kitchen counter for more than 5 minutes without needing to sit. I cannot carry grocery bags more than 20 feet. I stopped playing with my grandchildren on the floor two years ago because I cannot kneel. At work, I had to request a ground-floor assignment and a stool at my workstation. I take three rest breaks per hour that I did not need before my arthritis progressed.

Examiner listens for: Concrete examples of functional limitation, whether the veteran has modified their home or work environment, whether the veteran has reduced hours or changed jobs, and whether independence in self-care activities has been compromised.

Avoid: Avoid vague statements like 'I have some trouble with stairs.' Instead, say 'I can only climb one flight of stairs at a time, must use the handrail the entire time, and need to rest before descending.' Specificity directly informs the DBQ functional impact fields.

Assistive Device Use

How to describe it: If you use a cane, walker, crutches, wheelchair, or brace, describe which device, how often, for what activities, and whether it was prescribed by a physician. If you use a brace, describe which joints it supports and whether you wear it daily.

Example: I use a single-point cane every time I leave the house and on bad days inside the house as well. I was prescribed it by my VA primary care physician in [year]. During severe flare-ups, I require a rolling walker to get from my bedroom to my bathroom. My right knee brace was fitted by a VA orthopedist and I wear it every day.

Examiner listens for: Physician-prescribed vs. self-acquired devices, frequency of use, whether the device is required for safe ambulation vs. comfort, and whether multiple devices are used for different levels of activity.

Avoid: Do not leave assistive devices at home for the exam or fail to bring them. Arrive at the exam using any device you regularly use. The examiner should observe your actual ambulatory status, not your best-case presentation.

Stiffness (Morning and Post-Activity)

How to describe it: Describe the duration and severity of morning stiffness, post-rest stiffness, and stiffness after prolonged activity. Specify which joints are affected and how long stiffness lasts before you can move normally.

Example: Every morning I wake up with bilateral knee and hip stiffness that rates a 6/10 for the first 45-60 minutes. I cannot straighten my knees fully or descend stairs until I have been moving for at least 30 minutes. After sitting for more than 20 minutes during the day, I experience 'start-up' stiffness that makes the first several steps very painful and unstable.

Examiner listens for: Duration of morning stiffness (short duration is more typical of OA vs. RA), post-rest stiffness, and whether stiffness limits initiation of activity or sustained activity.

Avoid: Do not dismiss stiffness as 'just normal aging.' Morning stiffness and post-rest stiffness are documented features of osteoarthritis that contribute to functional limitation and should be described accurately and completely.
