Nondisp transverse fx unsp patella, 7thR

This code describes a patellar fracture that runs horizontally across the kneecap, where the bone fragments are still in their normal anatomical position. This specific code is used when the patient is receiving follow-up care for a severe open fracture (Type IIIA, IIIB, or IIIC) that has healed incorrectly, resulting in malunion.

Apply this code for subsequent encounters when a patient with a previously diagnosed nondisplaced transverse patellar fracture, initially classified as a severe open fracture, is being treated for complications related to malunion. This includes situations where surgical intervention or other treatments are being performed to address the improper healing.

• Ensure documentation clearly specifies "nondisplaced transverse" and "malunion" for the patella.
• Verify the initial injury was an open fracture type IIIA, IIIB, or IIIC to justify this specific code.
• This code is for subsequent encounters; an initial encounter for the acute fracture would use a different code.
