Unsp fx lower end unsp tibia, subs for clos fx w delay heal

This code signifies a follow-up encounter for a fracture located at the lower end of the tibia, where the specific type of fracture is not documented. The fracture was closed (skin intact), but the healing process is taking longer than expected.

This code is appropriate for subsequent visits when a patient is receiving ongoing care for a previously diagnosed, unspecified closed fracture of the distal tibia that is exhibiting delayed healing. It should be used when the specific fracture pattern (e.g., transverse, oblique) is not documented in the medical record.

• Ensure documentation clearly states "delayed healing" for the subsequent encounter.
• Verify that the fracture is indeed of the lower end of the tibia and that the specific type is unspecified.
• Do not use for initial encounters or for fractures that are healing normally.
