Complete transverse atyp femoral fracture, unsp leg, sequela

This code signifies a long-term complication or late effect resulting from a complete transverse atypical femoral fracture of an unspecified leg. An atypical femoral fracture is a rare type of stress fracture that occurs in the subtrochanteric region or femoral shaft, often associated with long-term bisphosphonate use. "Sequela" indicates that the acute phase of the fracture has passed, and the patient is now experiencing residual effects.

Use this code when documenting a patient presenting with a chronic condition or complication directly attributable to a previously healed or treated complete transverse atypical femoral fracture of an unspecified leg. This includes scenarios like nonunion, malunion, chronic pain, or functional limitations that persist after the initial fracture management. Documentation should clearly link the current condition to the prior atypical femoral fracture.

• Ensure documentation specifies "complete transverse atypical femoral fracture" and that the current encounter addresses a sequela, not the acute fracture.
• This code requires a seventh character 'S' for sequela, indicating the late effects of the injury.
• Do not use this code for the initial treatment or active healing phase of the fracture; instead, use codes from the M84.75- series without the 'S' seventh character.
