Nondisp transverse fx unsp patella, 7thF

This code describes a follow-up encounter for a patellar (kneecap) fracture that runs straight across the bone and has not shifted out of alignment. Importantly, this specific fracture was an open fracture, meaning the skin was broken, and it was classified as a severe type (IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification, but is now healing routinely.

This code is appropriate for subsequent visits where a patient is receiving ongoing care for a previously diagnosed nondisplaced transverse open patella fracture (Gustilo type IIIA, IIIB, or IIIC) that is progressing as expected. It would be used when the patient is no longer in the initial active treatment phase but is still under medical supervision for healing.

• Ensure documentation clearly specifies a "subsequent encounter" and "routine healing" for an open fracture.
• Verify the original fracture was indeed a nondisplaced transverse patella fracture and was classified as Gustilo type IIIA, IIIB, or IIIC.
• Do not use this code for initial treatment, malunion, nonunion, or delayed healing; separate codes exist for those scenarios.
