Joint Ankylosis (Rating Guide) VA Disability Rating

Diagnostic code 5256
By the editorial deskUpdated Jun 13, 2026Sources verified Jun 13, 2026
Quick summary
Ankylosis, a joint frozen solid by bone or fibrous union, has a dedicated code per joint: knee (diagnostic code 5256) rates 30 to 60 percent, hip (5250) 60 to 90, shoulder (5200) 30 to 50 by handedness, wrist (5214) 30 to 50, ankle (5270) 20 to 40, and unfavorable ankylosis of the entire spine rates 100. The angle the joint froze at decides favorable versus unfavorable, and unfavorable always rates higher.
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 20% to 100% under diagnostic code 5256, using the criteria in the rating table below.
  • The percentage assigned turns on Joint position and 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.

Ankle fused in a favorable position

Illustrates 20%

Situation. The ankle is fused (ankylosed) in plantar flexion of less than 30 degrees.

How the criteria apply. Ankle ankylosis in plantar flexion less than 30 degrees rates 20 percent under the ankylosis codes (DC 5256 family).

Knee fused near straight

Illustrates 30%

Situation. The knee is fused at a favorable angle in full extension or slight flexion.

How the criteria apply. Knee ankylosis at a favorable angle in full extension or slight flexion rates 30 percent under DC 5256.

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

A fused joint is rated by which joint and at what angle it froze. Surgical fusion counts the same as disease caused fusion.

What VA looks at

Imaging confirming the bony or fibrous union, the fixed angle, and the functional consequences for gait and use.

Common exam and DBQ topics

The fused position, how the limb is used around it, pain, adjacent joint strain.

Evidence that usually matters

Imaging, operative reports for surgical fusions, range of motion examinations confirming zero motion.

Common misunderstandings

Surgical fusion for a service connected joint keeps the service connection and rates under the ankylosis code, which often pays more than the painful motion rating it replaced. Adjacent joints that compensate and wear out support secondary claims.

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.
