Displ longitud fx unsp patella, 7thM

This code signifies a specific type of patellar fracture where the bone fragments are no longer aligned (displaced) and the break runs lengthwise along the patella. It specifically applies to an open fracture (skin broken) that is either Type I or II according to the Gustilo-Anderson classification, and importantly, the fracture has failed to heal properly after an initial treatment (nonunion). This is for a patient who is returning for follow-up care related to this ongoing healing issue.

Use this code for patients presenting for follow-up care of a previously treated open patellar fracture (Gustilo Type I or II) that has been documented as a displaced longitudinal fracture and has subsequently developed nonunion. This code is appropriate when the patient is in the active phase of treatment for the nonunion, such as during evaluation for surgical intervention or monitoring of conservative management.

• Ensure documentation clearly specifies "displaced longitudinal" and "open fracture Type I or II" of the patella.
• Verify that "nonunion" is explicitly stated, indicating the fracture has failed to heal.
• Confirm this is a "subsequent encounter" for ongoing care of the nonunion, not the initial treatment.
