Pathological fracture, unsp ankle, subs for fx w routn heal

This code signifies a pathological fracture of an unspecified ankle that is currently undergoing routine healing. A pathological fracture occurs due to a disease process weakening the bone, rather than from trauma. The "subsequent encounter" indicates the patient is receiving follow-up care for the healing fracture.

Apply this code for patients presenting for routine follow-up appointments for a pathological ankle fracture that is healing normally. Documentation should clearly state a pathological fracture of the ankle and indicate a subsequent encounter for healing, without complications. This code is appropriate when the specific ankle (right or left) is not documented.

• Always specify the laterality (right or left ankle) if documented; "unspecified" should be a last resort.
• Ensure documentation confirms the fracture is pathological, not traumatic.
• Distinguish between routine healing (D) and delayed healing (G), nonunion (K), or malunion (P) for subsequent encounters.
