Unsp fracture of l low leg, subs for clos fx w delay heal

This code signifies a fracture of the lower leg on the left side, where the specific bone involved (e.g., tibia, fibula) is not documented. It indicates that the fracture is closed (skin intact) and the patient is receiving follow-up care because the healing process is taking longer than expected.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed, unspecified closed fracture of the left lower leg is experiencing delayed union or nonunion, and the physician is actively managing this delayed healing. It should be used when the initial fracture site is not precisely identified in the medical record.

• Ensure documentation clearly states "delayed healing" or similar terminology for a closed fracture of the left lower leg.
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
• Avoid using this code if the specific bone fractured (tibia or fibula) is documented; instead, use the more specific fracture code with the appropriate "G" seventh character.
