How VA Rates Ankle Pain: DC 5270-5274 Motion and Instability Criteria

Diagnostic Code 5271 is the most common diagnostic code for ankle sprains, chronic instability, and degenerative arthritis. It provides two compensable rating levels: 10% for moderate limitation of motion (dorsiflexion less than 15 degrees, or plantar flexion less than 30 degrees), and 20% for marked limitation of motion (dorsiflexion limited to less than 5 degrees, or plantar flexion limited to less than 10 degrees).

When an ankle joint is completely stiffened or surgically fused (arthrodesis), it is rated under DC 5270 as ankylosis. If the joint is fixed in a favorable position (plantar flexion less than 30 degrees), the rating is 20%. If fixed in plantar flexion between 30 and 40 degrees, the rating is 30%. If fixed in extreme plantar flexion of more than 40 degrees, or in dorsiflexion, the rating is 40%.

Ankylosis or severe arthritis of the subtalar or tarsal joints is evaluated under DC 5272. If the joint is stiffened in a good weight-bearing position, the rating is 10%. If fixed in a poor weight-bearing position with pain or alignment deformity, the evaluation is 20%. This code addresses side-to-side inversion and eversion difficulties rather than up-and-down motion.

Under 38 CFR 4.59, the rating schedule intends to recognize actually painful, unstable, or malaligned joints as entitled to at least the minimum compensable evaluation for the joint, where applicable. While §4.59 establishes this principle for painful motion, it is not a universal 10% rule for every joint; for example, the minimum compensable rating under DC 5271 for limited ankle motion is 10%, but the joint must meet the regulatory criteria for compensable evaluation. Separately, 38 CFR 4.40 and 4.45 govern functional loss due to pain, weakness, fatigue, and incoordination during active use and flare-ups. When both ankles are service-connected, the VA combines their ratings and applies the 10% bilateral factor under 38 CFR 4.26, increasing the overall disability score before final rounding.

Strong claims include an Ankle Conditions DBQ with goniometer measurements for dorsiflexion, plantar flexion, inversion, and eversion. Weight-bearing radiographs, MRI scans documenting ligament tears or cartilage loss, and physical therapy records detailing balance instability corroborate functional loss.
