Chronic Exertional Compartment Syndrome VA Disability Rating

Diagnostic code 5311
By the editorial deskUpdated Sep 17, 2026Sources verified Jun 13, 2026
Quick summary
Chronic exertional compartment syndrome has no dedicated diagnostic code, so VA rates it by analogy, most often under the muscle group codes for the affected compartment (for the lower leg, muscle groups XI and XII, diagnostic codes 5311 and 5312), from 0 percent for slight to 30 percent for severe muscle disability, or on neurological residuals where nerve damage dominates.
Key requirements
  • Service connection requires a current diagnosis, an in-service event or exposure, and a medical link (nexus) between the two.
  • VA assigns ratings of 0% to 30% under diagnostic code 5311, using the criteria in the rating table below.
  • The percentage assigned turns on Muscle disability severity.
  • Measured at the C&P exam: Goniometer, range of motion.
This page explains common evidence VA may consider when rating this condition. It is not medical advice and does not diagnose any condition. Talk with a licensed medical professional about diagnosis and treatment, and with a VA accredited representative (38 CFR 14.629) about a specific claim.

Illustrative scenarios showing how the criteria above are applied. These are educational examples, not a prediction of any individual veteran's rating.

Slight muscle disability

Illustrates 0%

Situation. The affected compartment shows slight muscle disability.

How the criteria apply. Slight muscle disability of the affected compartment rates 0 percent under DC 5311.

Moderate muscle disability

Illustrates 10%

Situation. There is loss of power, weakness, and fatigue with pain on use.

How the criteria apply. Moderate muscle disability with loss of power, weakness, fatigue, and pain on use rates 10 percent under DC 5311.

How the measurement should be taken. When this condition is rated on limitation of motion, the examiner is required to measure the joint with a goniometer, the instrument made to read the angle of a joint, and should not estimate the angle by sight. Under 38 CFR 4.46, the goniometer is described as indispensable for measuring limitation of motion in examinations within the Department of Veterans Affairs. If the exam report does not list goniometer readings in degrees, that can be a reason to question whether the exam was adequate. Read 38 CFR 4.46

The rating hangs on how the examiner grades the muscle disability: slight, moderate, moderately severe, or severe. Describing what happens on a run, the tightness, numbness, and forced stops, is what moves that grade.

What VA looks at

Compartment pressure testing or a surgical diagnosis, which compartments are involved, fasciotomy history, and the functional muscle deficit.

Common exam and DBQ topics

Symptoms with exertion and recovery time, fasciotomy results, numbness or foot drop, daily limits.

Evidence that usually matters

Compartment pressure measurements, operative reports from fasciotomy, physical therapy notes, statements describing exertion limits.

Common misunderstandings

Post fasciotomy scars and any nerve injury (such as superficial peroneal numbness) are separately ratable on top of the muscle rating.

If a VA decision on this came back wrong

You have three review lanes, pick the one that fits the situation.

Under the Appeals Modernization Act (38 CFR 3.2500), a Higher Level Review or a Board Appeal must be requested within one year of the decision notice. A Supplemental Claim can generally be filed at any time after the decision, but filing any of the three within that one year window is what keeps the claim continuously pursued and protects the original effective date; wait longer and a later award may start from the new filing date instead.

State benefits stack with VA disability

Your rating may also qualify you for state-level benefits.

VA compensation is federal, but every state layers its own benefits on top. Many states reduce or waive property tax for disabled veterans, and many offer license, tuition, or vehicle benefits at various rating levels. The thresholds, dollar amounts, and eligibility rules vary widely from state to state, so the reliable answer is always your own state's guide.
