Diagnostic Code 5227 · 38 CFR §4.71a
Ankylosis of the ring finger or little finger means complete loss of motion in that finger. These fingers contribute to grip power but are considered less functionally important than the thumb, index, or middle fingers. The VA assigns a 0% (non-compensable) rating for favorable ankylosis, but a compensable 10% rating may apply for unfavorable ankylosis or if it interferes with overall hand function.
| Rating | Criteria |
|---|---|
| 0% | 0% — Favorable ankylosis of ring or little finger (non-compensable but establishes service connection) |
| 10% | 10% — Unfavorable ankylosis or if it interferes with overall function of the hand |
Medical records documenting complete loss of motion (ankylosis) in the affected finger joints. X-rays or imaging showing joint fusion or fixation. Range of motion testing showing zero degrees of motion. Documentation of whether ankylosis is in favorable or unfavorable position. Service treatment records or nexus opinion linking the condition to military service.
