Diagnostic Code 5271 · 38 CFR §4.71a
DC 5271 covers limitation of motion of the ankle joint. Normal ankle dorsiflexion (pulling the foot upward) is 20 degrees and normal plantarflexion (pointing the foot downward) is 45 degrees. The regulation now defines specific degree thresholds: moderate limitation means less than 15 degrees dorsiflexion or less than 30 degrees plantar flexion, while marked limitation means less than 5 degrees dorsiflexion or less than 10 degrees plantar flexion. Veterans commonly develop ankle limitation from sprains, fractures, parachute landings, running on uneven terrain, and the repeated physical stress of military service.
| Rating | Criteria |
|---|---|
| 10% | Moderate limitation of ankle motion, defined as less than 15 degrees of dorsiflexion or less than 30 degrees of plantar flexion. Normal dorsiflexion is 20 degrees and normal plantarflexion is 45 degrees, so this represents a meaningful but partial loss of motion. |
| 20% | Marked limitation of ankle motion, defined as less than 5 degrees of dorsiflexion or less than 10 degrees of plantar flexion. This is the maximum rating under DC 5271 and represents near-total loss of ankle motion. |
Range of motion measurements of the ankle using a goniometer are the primary evidence. Medical records documenting ankle injuries during service, imaging studies, and treatment records are relevant. Because DC 5271 uses "moderate" and "marked" rather than specific degree measurements, the examiner and rater exercise some judgment. The DeLuca factors apply — document pain, weakness, and functional loss during flare-ups or repetitive use.
The regulation now specifies exact degree thresholds. Moderate limitation is defined as less than 15 degrees dorsiflexion or less than 30 degrees plantar flexion. Marked limitation is defined as less than 5 degrees dorsiflexion or less than 10 degrees plantar flexion. The examiner measures with a goniometer, and DeLuca factors (pain, weakness, fatigability) still apply to the overall functional assessment.
No. The maximum under DC 5271 is 20%. However, if your ankle is ankylosed (fused/immobile), DC 5270 provides ratings up to 40%. Other ankle conditions like instability or arthritis may also warrant separate evaluation.
