Contusion of unspecified ankle, sequela

This code signifies a bruise to an ankle, where the specific ankle (left or right) is not documented, and the injury is a long-term effect or complication of an initial injury. It indicates that the contusion is no longer in its acute phase but rather a residual condition.

Use this code when documentation clearly states a contusion of an unspecified ankle that is now a sequela, meaning it's a chronic or late effect of a previous injury. This would apply to situations where the patient presents for treatment of ongoing symptoms directly related to an old ankle bruise.

• Requires an additional code to identify the original cause of the sequela.
• Only use when the laterality of the ankle is not specified in the medical record.
• Distinguish from acute contusions, which would use codes without the "S" seventh character.
