Path fracture in oth disease, unsp ulna and radius, sequela

This code signifies a pathological fracture of an unspecified ulna and radius that occurred due to an underlying disease process, and the patient is now experiencing a late effect or complication of that fracture. This indicates the acute phase of the fracture has passed, and the patient is dealing with residual issues.

Use this code when documentation clearly states a patient is presenting for treatment of a sequela (e.g., malunion, nonunion, chronic pain, deformity, limited range of motion) directly resulting from a pathological fracture of the forearm bones (ulna and radius) that occurred in the past due to another disease. The underlying disease causing the pathological fracture should also be coded.

• Always sequence this code after the code for the underlying disease that caused the pathological fracture.
• Ensure documentation specifies "sequela" or a late effect of the fracture; otherwise, an acute fracture code might be more appropriate.
• Avoid using this code if the specific bone (ulna or radius) is identified; instead, use a more specific code from the M84.63- series.
