Unsp fx low end unsp tibia, 7thQ

This code signifies a fracture of the lower part of the tibia, where the specific location within the lower end is not documented. It indicates that the fracture was initially an open fracture of type I or II, and the patient is now presenting for follow-up care due to the bone healing in an abnormal or misaligned position.

Apply this code when documentation confirms a subsequent encounter for an open tibia fracture (Gustilo type I or II) that has healed with malunion, and the precise site of the fracture within the distal tibia is not specified. This is appropriate for ongoing management of the malunion, such as planning for corrective surgery or monitoring conservative treatment.

• Ensure the documentation clearly states "subsequent encounter" and "malunion" for an open fracture.
• Verify that the initial open fracture was classified as type I or II; other open fracture types would require a different code.
• If the specific location of the fracture within the lower tibia is known, a more precise code should be selected.
