Unsp fx unsp lower leg, subs for clos fx w delay heal

This code signifies a fracture of the lower leg where the specific bone (tibia or fibula) and the exact location of the fracture are not documented. The fracture is closed, meaning the skin remains intact, and the patient is in a subsequent phase of care where the fracture is healing slower than expected.

This code is appropriate for follow-up encounters when a patient presents with a previously diagnosed, unspecified closed lower leg fracture that is demonstrating delayed healing. It should be used when the medical record lacks the specificity to identify the exact bone or location of the fracture.

• Ensure documentation clearly states "delayed healing" for a closed fracture.
• Only use this code when the specific bone (tibia/fibula) or fracture site is not specified in the medical record.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
