Stress fracture, left ankle, sequela

This code signifies the long-term effects or complications arising from a healed or resolved stress fracture of the left ankle. It indicates that the patient is experiencing residual symptoms or conditions directly attributable to the previous stress fracture, such as chronic pain, instability, or deformity, after the acute phase of the injury has passed.

Apply this code when documentation clearly indicates a sequela (late effect) of a prior stress fracture to the left ankle. This is appropriate for patients presenting with ongoing issues related to the healed fracture, not for the initial injury or subsequent acute exacerbations. Documentation should specify the left ankle and the nature of the sequela.

• Requires a secondary code to describe the specific sequela (e.g., chronic pain, malunion).
• Do not use for an active or acute stress fracture; refer to codes in the M84.372- series without the "S" seventh character.
• Ensure the medical record explicitly links the current condition as a direct consequence of the past left ankle stress fracture.
