Stress fracture, right ankle, sequela

This code identifies a stress fracture of the right ankle that is now a long-term consequence or late effect of the initial injury. It signifies that the acute phase of the stress fracture has passed, and the patient is experiencing residual symptoms or complications directly attributable to the prior fracture.

Apply this code when documentation indicates a patient is being treated for a current problem or condition that is a direct result of a previously healed or resolved stress fracture of the right ankle. This includes chronic pain, deformity, nonunion, or malunion stemming from the original injury. Documentation must clearly link the current condition to the past stress fracture.

• Requires a seventh character "S" for sequela, indicating a complication or residual effect of a past injury.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic pain, malunion).
• Do not use for acute or initial encounters for a stress fracture; those require different seventh characters.
