Pathological fracture, right ankle, subs for fx w nonunion

This code signifies a fracture of the right ankle that occurred due to an underlying disease process, rather than trauma. It specifically indicates that the fracture has not healed properly (nonunion) and the patient is currently receiving routine care during the healing or recovery phase.

Apply this code when documentation confirms a pathological fracture of the right ankle with evidence of nonunion, and the patient is in the subsequent phase of care. This includes follow-up visits for cast changes, wound care, or monitoring of the nonunion. Documentation should clearly state "pathological fracture," "right ankle," and "nonunion," along with the "subsequent encounter" status.

• Ensure documentation specifies "pathological fracture" to differentiate from traumatic fractures.
• Verify the laterality (right ankle) and the presence of nonunion are clearly stated.
• The "K" seventh character indicates subsequent encounter for a fracture with nonunion; do not use for initial or sequela encounters.
