Oth fx low end unsp tibia, 7thM

This code describes a situation where a patient has sustained an open fracture (Type I or II) of the lower end of the tibia, excluding the ankle, and is currently undergoing treatment for a nonunion of that fracture. The "unspecified" nature indicates that the laterality (left or right) of the tibia is not documented.

Use this code when documentation confirms an open fracture (Gustilo-Anderson Type I or II) of the distal tibia (not involving the ankle joint) that has failed to heal properly, and the patient is presenting for follow-up care, cast changes, or other ongoing management of the nonunion. This code is appropriate for subsequent encounters after the initial treatment of the fracture.

• Ensure the documentation clearly specifies an open fracture type I or II and a nonunion of the fracture.
• Verify that the fracture location is the lower end of the tibia, excluding the ankle.
• Confirm this is a subsequent encounter for ongoing treatment of the nonunion, not the initial treatment of the fracture.
