Nondisp longitud fx r patella, 7thM

This code signifies a follow-up encounter for a right patellar fracture that runs lengthwise and has not shifted from its normal position. The initial injury was an open fracture, classified as type I or II, and the bone has failed to heal properly.

This code is appropriate when a patient presents for ongoing management of a previously sustained open longitudinal patellar fracture (type I or II) that is now complicated by nonunion. It indicates that the fracture fragments are still aligned but healing has not occurred as expected.

• Ensure documentation clearly specifies "nondisplaced," "longitudinal," and "right patella."
• Verify the original injury was an "open fracture type I or II" and that "nonunion" is explicitly stated.
• This code is for subsequent encounters; an initial encounter would use a different code.
