Sprain of interphalangeal joint of unsp great toe, sequela

This code signifies a chronic or late effect resulting from a sprain of the interphalangeal joint of an unspecified great toe. This means the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past sprain.

Apply this code when documentation indicates a patient is presenting for treatment of a long-term consequence of a sprained great toe interphalangeal joint, such as chronic pain, stiffness, or instability, after the acute phase of the injury has passed. This code is appropriate when the specific great toe (left or right) is not documented.

• Always sequence this "S" code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, osteoarthritis).
• Ensure the medical record clearly links the current condition to a past interphalangeal joint sprain of the great toe.
• Avoid using this code for acute or subacute sprains; those require the initial encounter or subsequent encounter codes.
