Unsp fx shaft of r femr, 7thN

This code describes a situation where a patient is receiving ongoing care for a previously diagnosed, unspecified fracture of the shaft of their right femur. The fracture was an open type IIIA, IIIB, or IIIC, and has failed to heal properly, resulting in a nonunion.

This code is appropriate for encounters where a patient is being treated for the nonunion of an open right femoral shaft fracture (types IIIA, IIIB, or IIIC) that was previously sustained. This includes follow-up visits, surgical interventions for the nonunion, or management of complications related to the nonunion.

• Always sequence this code after the initial encounter code for the fracture.
• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify the laterality (right femur) and the specific location (shaft) are documented.
