Path fracture in neoplastic disease, unsp foot, sequela

This code signifies a pathological fracture of an unspecified foot bone that occurred due to an underlying neoplastic disease, where the patient is now presenting for treatment of the late effects or complications of that fracture. This indicates the acute phase of the fracture has passed, and the current encounter addresses residual problems directly related to the prior fracture.

Apply this code when documentation clearly indicates a healed or healing pathological fracture of the foot, secondary to cancer, and the patient is being treated for a sequela (e.g., malunion, nonunion, chronic pain, deformity, functional limitation) of that fracture. The medical record should specify the foot as the affected site and confirm the neoplastic etiology of the original fracture.

• Always sequence this sequela code after the code for the underlying neoplastic disease (C00-D49).
• Ensure documentation explicitly states "sequela," "late effect," or describes a chronic complication of a previously treated pathological fracture.
• Do not use for acute pathological fractures; those require codes from the M84.57- series without the "S" seventh character.
