Nondisp fx of r tibial tuberosity, 7thN

This code describes a right tibial tuberosity fracture that was initially open (meaning the bone broke through the skin) and is now being treated in a later stage for a failure of the bone to heal properly (nonunion). The "nondisplaced" aspect indicates the bone fragments are still in their normal anatomical alignment. The open fracture type IIIA, IIIB, or IIIC specifies the severity of the soft tissue damage and contamination at the time of the initial injury.

This code is used when a patient presents for follow-up care, surgical intervention, or ongoing management of a previously diagnosed open right tibial tuberosity fracture that has not healed. This includes situations where additional procedures are performed to promote union, such as bone grafting or revision fixation, or when monitoring the progression of the nonunion.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for the fracture.
• Verify the original injury was an open fracture of type IIIA, IIIB, or IIIC.
• Do not use this code for initial encounters or for fractures that are healing normally.
