How to code Ankle Pain
Ankle pain is M25.57-, which covers the ankle and the joints of the foot: M25.571 right, M25.572 left, and M25.579 unspecified. Pain in both ankles takes both side codes.
Other ankle symptoms follow the same pattern: M25.471 or M25.472 for ankle effusion and M25.671 or M25.672 for ankle stiffness. Pain in the foot outside the joints is M79.67-, such as M79.671.
An injury replaces the pain code. An ankle sprain with no ligament named is S93.401A (right) or S93.402A (left) at the first encounter, with an external cause code for how it happened. Osteoarthritis of the ankle and foot is M19.071 or M19.072. See the ankle fracture guide for fracture codes.
