Nondisp longitud fx unsp patella, 7thM

This code describes a situation where a patient is receiving follow-up care for a patellar fracture that runs lengthwise (longitudinal) and has not shifted out of place. Importantly, this fracture was initially an open fracture (skin broken) of type I or II, and it has not healed properly (nonunion).

This code is used for subsequent encounters, such as office visits, hospital stays, or surgical procedures, where the primary focus is managing the nonunion of a previously treated nondisplaced longitudinal open patellar fracture. It applies when the patient is still undergoing treatment for the nonunion, rather than initial treatment or routine follow-up for a healed fracture.

• Ensure documentation clearly states "nonunion" and specifies the initial open fracture type (I or II).
• Verify that the encounter is for ongoing management of the nonunion, not for initial treatment or routine follow-up of a healed fracture.
• Confirm the fracture is longitudinal and nondisplaced, and located in an unspecified patella.
