Path fx in oth disease, r radius, subs for fx w malunion

This code signifies a right radius fracture that occurred due to an underlying disease process, not trauma, and is currently being treated for a malunion. Malunion indicates that the fracture has healed, but in an unsatisfactory position or alignment, requiring further management. The "subsequent encounter" aspect means the patient is receiving routine care during the healing or recovery phase of this malunited pathological fracture.

Use this code when a patient presents for follow-up care of a right radial fracture that was caused by a systemic disease (e.g., osteoporosis, bone tumor) and has healed incorrectly. Documentation should clearly state "pathological fracture," specify the right radius, confirm malunion, and indicate that the visit is for ongoing management rather than initial treatment.

• Ensure documentation explicitly states "pathological fracture" and the specific bone involved (right radius).
• Verify that the encounter is for a subsequent visit for the malunion, not initial treatment or sequela.
• Always code the underlying disease causing the pathological fracture first, followed by this fracture code.
