  • Note: Also consider whether evaluation as amputation is warranted and whether an additional evaluation is warranted for resulting limitation of motion of other digits or interference with overall function of the hand.

Ankylosis of the Long Finger (VA Diagnostic Code 5226)

Understanding This Condition

Ankylosis of the long finger is a musculoskeletal condition rated under VA Diagnostic Code 5226 (§ 4.71a). "Ankylosis" refers to stiffening or fixation of a joint, meaning the long finger (the middle finger) is unable to move normally.

The VA distinguishes between two forms of ankylosis for rating purposes:

  • Favorable ankylosis
  • Unfavorable ankylosis

Available Rating Levels

For ankylosis of the long finger, the rating schedule provides a single evaluation level:

RatingCriteriaNon-Dominant (Minor) Extremity
10%Unfavorable or favorable10%

Under this diagnostic code, both favorable and unfavorable ankylosis are evaluated at 10%, and the rating is the same whether the affected hand is the dominant or non-dominant (minor) extremity.

What the VA Looks For

When rating ankylosis of the long finger, the VA considers the following, as noted in the rating schedule:

  • Whether evaluation as amputation is warranted — In some cases, the VA considers whether the level of impairment is comparable to amputation.
  • Whether an additional evaluation is warranted for:
    • Resulting limitation of motion of other digits, or
    • Interference with the overall function of the hand.

These considerations help ensure the evaluation reflects the full impact of the condition on hand function.

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 5226 and attach the evidence for the level you are asking for. Other Musculoskeletal System codes may cover your secondary conditions.
