Unsp fx low end r femr, subs for opn fx type I/2 w nonunion

This code signifies a persistent failure of bone healing in an open fracture of the lower right femur, specifically a Type I or II open fracture. The fracture type at the lower end of the femur is not further specified. This diagnosis indicates that the initial injury was an open fracture, and despite treatment, the bone fragments have not united.

Use this code for follow-up encounters where a patient is being treated for a nonunion of an open Type I or II fracture of the distal right femur. This applies when the specific type of fracture (e.g., supracondylar, condylar) is not documented. It is appropriate for ongoing management, such as surgical intervention for nonunion or continued conservative treatment.

• Always confirm the laterality (right) and the encounter type (subsequent for nonunion).
• Ensure documentation specifies an "open fracture type I or II" for the initial injury, even if the current encounter is for nonunion.
• If the specific type of fracture at the lower end of the femur is known and documented, a more specific code should be sought.
