Pathological fracture, right foot, subs for fx w malunion

This code signifies a pathological fracture in the right foot that has previously been treated but has healed incorrectly, resulting in a malunion. A pathological fracture occurs due to a disease process weakening the bone, rather than from significant trauma. The "subsequent encounter" indicates the patient is receiving routine care during the healing or recovery phase for this malunited fracture.

Use this code when a patient presents for follow-up care, cast changes, physical therapy, or other ongoing management related to a right foot pathological fracture that has healed in a misaligned position. Documentation should clearly state "pathological fracture," specify the "right foot," confirm "malunion," and indicate that the encounter is for "subsequent" care.

• Ensure documentation explicitly states "pathological fracture" to differentiate from traumatic fractures.
• Verify the laterality (right foot) and the presence of "malunion" in the physician's notes.
• Always sequence this code after the underlying condition causing the pathological fracture (e.g., osteoporosis, neoplasm) if that condition is still active and being treated.
