Foot and Ankle C&P Exam Guide: DBQs, Range of Motion, and Functional Loss

VA disability claims for lower extremity distal joints are evaluated using two distinct disability questionnaires: the Foot Conditions DBQ (covering plantar fasciitis, pes planus, and toe deformities) and the Ankle Conditions DBQ (covering ankle motion limitation, ankylosis, instability, and replacement). Examiners perform physical inspections, weight-bearing evaluations, goniometer range of motion testing, and functional loss assessments.

Diagnostic Code 5271 evaluates limitation of motion of the ankle joint based on strict regulatory degree thresholds, not subjective descriptions. A 20% rating for marked limitation of motion requires dorsiflexion limited to less than 5 degrees, or plantar flexion limited to less than 10 degrees. A 10% rating for moderate limitation of motion requires dorsiflexion limited to less than 15 degrees, or plantar flexion limited to less than 30 degrees. Normal ankle motion is 20 degrees dorsiflexion and 45 degrees plantar flexion.

The ankle joint primarily controls up-and-down motion (plantar flexion and dorsiflexion). Side-to-side rotation (inversion and eversion) occurs at the subtalar and tarsal joints. Under DC 5272, ankylosis or severe arthritis of the subastragalar joint is rated at 10% if fixed in a good weight-bearing position, or 20% if fixed in a poor weight-bearing position with alignment deformity and persistent pain.

During the foot examination, the examiner inspects the veteran while standing to evaluate weight-bearing posture. For pes planus under DC 5276, the clinician documents whether the weight-bearing line is over or medial to the great toe, inward bowing of the tendo achillis, pain on manipulation and use of the feet, objective marked deformity (such as pronation or abduction), swelling on use, characteristic callosities, extreme tenderness of plantar surfaces, and severe spasm of the tendo achillis on manipulation, along with response to built-up shoes or orthopedic appliances. For plantar fasciitis under DC 5269, the examiner palpates the medial calcaneal tubercle and records treatment response.

Examiners are required by law to evaluate functional loss caused by repetitive walking, standing, and flare-ups under 38 CFR 4.40 and 4.45. Separately, 38 CFR 4.59 recognizes that actually painful, unstable, or malaligned joints warrant at least the minimum compensable evaluation for the joint, where applicable. However, §4.59 is not a universal 10% rule that applies across all extremity conditions regardless of whether a minimum compensable rating exists under the specific diagnostic code. Furthermore, clinical testing does not stop at the first report of pain; examiners must record the complete arc of motion and document where pain begins and how motion diminishes with repetitive use.
