Oth fx right patella, subs for opn fx type I/2 w delay heal

This code signifies a fracture of the right kneecap that is not classified as a simple transverse, stellate, or longitudinal fracture, and has broken through the skin (open fracture type I or II). The patient is currently receiving care for this fracture, and the healing process is taking longer than expected.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed open type I or II fracture of the right patella is experiencing delayed union or nonunion. It should be used when the patient is still under active treatment for the fracture and its delayed healing.

• Ensure documentation specifies an "other" type of patellar fracture and an open wound classified as Type I or II.
• Verify that the encounter is for subsequent care and explicitly mentions delayed healing.
• Always sequence this code after the primary fracture code if applicable, or as the primary diagnosis if the delayed healing is the focus of the encounter.
