Path fx, unsp tibia and fibula, subs for fx w routn heal

This code signifies a fracture of an unspecified tibia and fibula that occurred due to an underlying disease process, rather than trauma. The patient is in the healing phase, and the fracture is progressing routinely without complications. This indicates a follow-up visit for ongoing management of the pathological fracture.

Use this code for follow-up encounters when a patient with a pathological fracture of the tibia and fibula is exhibiting routine healing. Documentation should clearly state "pathological fracture," specify "tibia and fibula" (or an unspecified location if both are involved and not specified individually), and indicate a "subsequent encounter" with "routine healing."

• Ensure the documentation explicitly states "pathological fracture" to differentiate from traumatic fractures.
• Verify the encounter is for follow-up care during the healing phase, not initial treatment or a nonunion.
• Do not use this code if the fracture is healing with a delayed union or nonunion; different codes apply for those scenarios.
