Pathological fracture, right femur, sequela

This code signifies a pathological fracture of the right femur where the acute phase of the fracture has passed, and the patient is now experiencing the long-term effects or complications of that previous fracture. This could include nonunion, malunion, chronic pain, or functional limitations directly attributable to the healed or resolving pathological fracture.

Apply this code when documentation clearly indicates a patient is being treated for a residual condition or late effect stemming from a prior pathological fracture of the right femur. This is appropriate for follow-up visits, rehabilitation, or management of chronic issues related to the healed or resolving fracture. Documentation should specify the "sequela" or "late effect" of the previous fracture.

• Always sequence this sequela code after the code for the specific sequela (e.g., nonunion, malunion).
• Do not use this code for an active pathological fracture; use the acute pathological fracture codes (M84.451A-M84.451P) for initial or subsequent encounters.
• Ensure the medical record explicitly links the current condition to a past pathological fracture of the right femur.
