Unsp fx shaft of r femr, subs for opn fx type I/2 w malunion

This code describes a previously sustained, unspecified fracture of the shaft of the right femur that was initially an open fracture of Gustilo type I or II. The fracture has now healed in an unsatisfactory position, resulting in a malunion. This indicates a later stage of care where the bone has united, but with an anatomical deformity.

This code is used for follow-up encounters when a patient presents with complications from a malunited, previously open, unspecified right femoral shaft fracture. It applies when the initial injury was classified as an open fracture type I or II. This code would be appropriate for assessing the functional impact of the malunion or planning corrective procedures.

• Ensure documentation clearly specifies "malunion" and that the initial fracture was an "open fracture type I or II."
• Verify the laterality (right femur) and the specific bone section (shaft) are documented.
• Do not use this code for initial fracture treatment or for nonunion; separate codes exist for those scenarios.
