Nondisp transverse fx unsp patella, 7thM

This code describes a transverse fracture of the kneecap that has not shifted out of alignment, and the bone fragments have failed to heal together. This specific code is used when the initial injury was an open fracture (meaning the skin was broken) of Type I or II severity, and the patient is now presenting for follow-up care related to the nonunion.

Apply this code for a patient presenting for ongoing management of a previously diagnosed, nondisplaced transverse patellar fracture that has not healed. The original injury must have been an open fracture, and the current encounter addresses the persistent nonunion. This would be appropriate for clinic visits, imaging studies, or surgical planning related to the nonunion.

• Ensure documentation clearly states "nondisplaced," "transverse," and "nonunion" of the patella.
• Verify the original fracture was an open fracture, specifically Type I or II, as this impacts the seventh character.
• This "M" seventh character indicates subsequent care for a nonunion; do not use for initial treatment or routine healing.
