Osteomyelitis C&P Exam Prep

Range of Motion (ROM) Testing - Affected Joint(s)

What it measures: Degree of joint mobility lost due to osteomyelitis extending into or adjacent to major joints. Relevant when osteomyelitis has involved or extended into the shoulder, elbow, wrist, hip, knee, ankle, or hand/foot joints.

What to expect: The examiner will use a goniometer to measure active ROM (you move the joint yourself), passive ROM (examiner moves the joint), and may assess weight-bearing versus non-weight-bearing ROM for lower extremity joints. Testing may be repeated to assess fatigue-related decline.

Pain considerations: Pain during ROM is a DeLuca factor and must be reported. State: 'I experience pain at [X degrees] of motion that rates [number] on a 10-point scale.' Inform the examiner if the ROM demonstrated today is better than your typical function due to the exam setting, nervousness, or a good day.

Physical Inspection of Affected Bone Site

What it measures: Visual and palpation assessment for signs of active or residual osteomyelitis including soft tissue swelling, erythema, warmth, tenderness, and presence of discharging sinus tracts.

What to expect: The examiner will visually inspect and gently palpate the affected area. They will look for draining sinus tracts, scar tissue from prior sinuses, skin changes, and localized tenderness over the bone. If a sinus is present, they will document its characteristics.

Pain considerations: Bone tenderness on palpation is significant. Do not minimize pain response during palpation. Accurately convey the degree of tenderness you feel. State if palpation causes pain that radiates or causes you to involuntarily guard the area.

Laboratory and Diagnostic Test Review

What it measures: Objective evidence of active or historical infection through CBC (anemia, leukocytosis), ESR, CRP, blood cultures, and bone biopsy/culture results. Imaging via X-ray, MRI, and bone scan documents structural bone changes including involucrum, sequestrum, and periosteal reaction.

What to expect: The examiner will review your available test results. They may order or reference CBC, ESR, CRP, MRI, bone scan, X-ray, blood culture, or bone biopsy results. Bring all available records including dates and lab values.

Pain considerations: Lab results do not capture pain. Pain, fatigue, weakness, and functional impact must be communicated verbally during the interview portion of the exam regardless of what lab values show.

Constitutional Symptoms Assessment

What it measures: The presence and continuity of systemic symptoms resulting from osteomyelitis: fever, malaise, fatigue, unintentional weight loss, anemia, and secondary amyloid changes. These are critical to differentiate 60% from 100% ratings.

What to expect: The examiner will ask about systemic symptoms during active episodes and between episodes. They will inquire whether constitutional symptoms are continuous or only present during flares. Bring documentation of hospitalizations, documented fevers, weight loss records, and any specialist notes.

Pain considerations: Fatigue and malaise are DeLuca-relevant factors. Describe how constitutional symptoms affect your ability to work, exercise, perform household tasks, and maintain social functioning even on your relatively better days.

100%

Osteomyelitis of the pelvis or vertebrae; OR osteomyelitis extending into major joints; OR osteomyelitis with multiple localization; OR with a long history of intractability and debility, anemia, amyloid liver changes, or other continuous constitutional symptoms. Per Huerta v. McDonough (2021), active infection is NOT required for 100%.

From 38 CFR: Per M21-1 Part V, Subpart iii, 1.D.1.e: 100% does not require active infection. Veteran with osteomyelitis of the pelvis following bone graft injury, treated with antibiotics but with continuous debility, qualifies at 100%. Osteomyelitis extending into knee joint with long history of intractability qualifies at 100%.

60%

Frequent episodes with constitutional symptoms. Constitutional symptoms are a prerequisite for this rating level. Per M21-1, the 60% rating is based specifically on constitutional symptoms present during frequent episodes - distinct from the continuous constitutional symptoms required for 100%.

From 38 CFR: Veteran with osteomyelitis of the tibia who has had 4 episodes in the past 3 years, each requiring IV antibiotic treatment and causing fever, malaise, and inability to work for weeks at a time, would support a 60% rating with documentation of constitutional symptoms during those episodes.

30%

With definite involucrum or sequestrum, with or without discharging sinus. The involucrum or sequestrum must be definitively confirmed on imaging - not merely suggested or possible.

From 38 CFR: Veteran with chronic osteomyelitis of the femur where X-ray or MRI definitively shows an involucrum (shell of new bone) or a sequestrum (fragment of dead bone) qualifies at 30% regardless of whether a discharging sinus is currently present.

20%

With discharging sinus OR other evidence of active infection within the past 5 years. This rating has two distinct bases: (1) a currently active discharging sinus, and (2) a historical evaluation based on evidence of active infection within the past 5 years. These are separate and distinct qualifying pathways.

From 38 CFR: Per M21-1: The 20% historical evaluation based on evidence of active infection within the past 5 years must be distinguished from the 20% evaluation for a discharging sinus. A veteran with a documented hospitalization and IV antibiotic treatment for osteomyelitis recurrence within the last 5 years qualifies at 20% even if currently asymptomatic and without a sinus.

10%

Inactive osteomyelitis following repeated episodes (2 or more recurrences following the initial infection), without evidence of active infection in the past 5 years. This is a historical evaluation assigned once to cover all previously active sites. Per M21-1, 2 or more episodes following the initial infection are required.

From 38 CFR: Veteran with initial osteomyelitis during service, with 2 subsequent recurrences (the last being more than 5 years ago), currently showing no active infection signs, qualifies at 10%. The 10% rating is assigned once to cover all previously active infection sites. Per Note 1 in DC 5000: a 10% rating as an exception to the amputation rule is assigned in any case of active osteomyelitis where the amputation rating for the affected part is 0%.

Pain

How to describe it: Describe the location, character (sharp, deep, aching, throbbing, burning), intensity on a 0-10 scale on your average day versus your worst day, and what activities or conditions worsen or relieve pain. Distinguish between pain at rest, pain with movement, and pain during active infection episodes.

Example: On my worst days, the deep aching pain in my [tibia/femur/etc.] is an 8 or 9 out of 10. I cannot bear weight, walking more than 10 feet requires stopping, and I need to elevate and ice the area continuously. The pain prevents me from sleeping through the night and I have to take [medication] every [X] hours just to manage it.

Examiner listens for: Bone pain distinct from soft tissue pain; pain that correlates with periods of active infection; pain on palpation of the bone; pain that persists between active episodes indicating residual damage; pain that limits function in ways consistent with the affected site.

Avoid: Do not say 'it's manageable' or 'I've gotten used to it' without clarifying what that management actually requires. Do not describe your best day's pain level - describe your typical and worst day levels explicitly.

Constitutional Symptoms (Fever, Malaise, Fatigue, Weight Loss)

How to describe it: For each constitutional symptom, specify: how often it occurs, whether it is present only during active episodes or also between episodes, its severity and duration, and how it limits daily functioning. The distinction between episodic versus continuous constitutional symptoms is critical to differentiating 60% from 100% ratings.

Example: During my flares, I run a fever of [temperature], I'm completely exhausted and can't get out of bed for days at a time, I lose my appetite and drop [X] pounds during each episode, and I feel generally ill and unable to function. Even between flares, I have chronic fatigue that limits me to [X] hours of activity before I must rest, and I never feel fully well.

Examiner listens for: Whether constitutional symptoms are present continuously (supporting 100%) or only during episodes (supporting 60%); the frequency of episodes; objective correlates like documented fevers in medical records; anemia on CBC; any amyloid-related organ changes.

Avoid: Do not minimize fatigue as 'just being tired' - describe it as a systemic exhaustion that does not resolve with rest. Do not fail to mention weight loss, even if you have since regained the weight. Do not say constitutional symptoms only happen 'sometimes' if they are a recurring pattern with each episode.

Episode Frequency and Recurrence History

How to describe it: Provide the examiner with a clear chronological account of every episode of osteomyelitis: initial infection date and site, each recurrence date and site, how each episode was diagnosed (imaging, culture, clinical exam), how each was treated (oral antibiotics, IV antibiotics, surgery), and how long each episode lasted.

Example: My initial infection was in [year] during service. I had my first recurrence in [year] requiring [X weeks] of IV antibiotics and hospitalization. My second recurrence was in [year] at the same site, requiring debridement surgery. Each recurrence lasts [X weeks/months] and completely takes me off my feet during that time.

Examiner listens for: Total number of recurrences following the initial infection (minimum 2 required for 10% inactive rating); frequency of episodes (supports 60% if frequent with constitutional symptoms); evidence that episodes are documented in medical records; whether the most recent episode was within 5 years (critical for 20% versus 10%).

Avoid: Do not vaguely state you've had 'a few' recurrences - provide specific dates and documentation. Do not omit any episode even if it seemed minor or resolved quickly with antibiotics. Every documented recurrence counts toward the rating criteria.

Discharging Sinus

How to describe it: If you have or have had a discharging sinus, describe its location, when it first appeared, how often it drains, what the discharge looks like (purulent, serous, blood-tinged), whether it has ever closed and re-opened, and how it affects hygiene, daily activities, and social functioning.

Example: My discharging sinus on my [leg/arm/etc.] drains continuously and I have to change dressings [X] times per day. The drainage has a foul odor that causes me significant embarrassment in social situations. The wound area is painful and the constant drainage has caused skin breakdown around the sinus opening.

Examiner listens for: Whether a discharging sinus is currently active (supports minimum 20%); whether a prior sinus has left scarring or evidence; whether the sinus is associated with an involucrum or sequestrum (supports 30%); whether the sinus is associated with extension into a major joint (supports 100%).

Avoid: Do not fail to show the examiner an active sinus or scarring from a prior sinus. Do not understate the impact of wound care burden on daily life. If the sinus drains intermittently, clarify that it was active within the qualifying time period using medical records.

Functional Limitations and Assistive Device Use

How to describe it: Describe specifically how osteomyelitis limits your ability to walk, stand, lift, carry, climb stairs, drive, work, perform self-care, and engage in recreational activities. If you use a cane, crutches, walker, brace, or wheelchair due to osteomyelitis, describe how often you use it and why.

Example: On a bad day or during a flare, I cannot walk more than 50 feet without severe bone pain. I use crutches during active episodes and a cane on most other days. I cannot stand for more than [X] minutes without needing to sit, and I cannot kneel, squat, or climb ladders at all. I had to change jobs/stop working because I can no longer [describe prior duties].

Examiner listens for: Functional limitations that correlate with the affected bone and joint sites; use of prescribed versus self-selected assistive devices; need for dressing changes or wound care; limitations in occupational and recreational activities; how symptoms affect activities of daily living.

Avoid: Do not leave assistive devices at home on exam day if you typically use them. Do not say you 'get around fine' if you modify activities to avoid pain - describe those modifications. Do not omit limitations that seem unrelated to your primary complaint if they stem from the osteomyelitis site.
