Favorable Ankylosis of Five Digits of One Hand (Diagnostic Code 5220)

Understanding This Condition

Diagnostic Code 5220 covers favorable ankylosis of all five digits of one hand. This condition falls under the Musculoskeletal System and is rated under 38 CFR § 4.71a.

Ankylosis refers to the stiffening or fixation of a joint, meaning the affected digits are no longer able to move freely. "Favorable" ankylosis describes a specific fixed position of the joints. In this diagnostic code, the condition affects all five digits (the thumb and four fingers) of a single hand.

Available Rating Levels

The VA rating for this condition depends on whether the affected hand is your dominant (major) or non-dominant (minor) extremity:

What the VA Looks For

When evaluating a claim under Diagnostic Code 5220, the VA considers:

  • Favorable ankylosis affecting all five digits of one hand
  • Which hand is affected — the rating differs depending on whether the condition involves your dominant or non-dominant hand

This information is provided for general educational purposes and is drawn directly from the VA rating schedule under 38 CFR § 4.71a. It is not legal advice, and it does not guarantee any particular rating or outcome. Every claim is evaluated based on individual medical evidence and circumstances.

These criteria are a rendering of § 4.71a, diagnostic code 5220. The official version is the one that governs your rating.

How to claim this

Knowing the criteria is the first half. Getting your file to show them is the second.

  1. Find your level in the stack

    Read each rung against what your medical records already say. The level your records document today is the one the VA can support today.

  2. Name the gap

    Look at the rung above yours and write down exactly what it asks for that your file does not show yet — a diagnosis, a measurement, a prescribed brace, a doctor’s opinion linking it to service.

  3. Claim it by code

    File under diagnostic code 5220 and attach the evidence for the level you are asking for. Other Musculoskeletal System codes may cover your secondary conditions.
