Oth fracture of unsp patella, subs for clos fx w delay heal

This code signifies a follow-up encounter for a patellar fracture that is not specifically classified as a transverse, longitudinal, or comminuted type, and the specific patella (left or right) is not documented. The fracture is closed, meaning the skin remains intact, but the healing process is taking longer than expected.

Use this code when a patient presents for ongoing management of an unhealed, closed patellar fracture that was previously treated, and the specific type of patellar fracture or laterality was not documented in the initial encounter. This applies to situations where the physician notes delayed union or nonunion of the fracture during a subsequent visit.

• Ensure documentation clearly indicates a "subsequent encounter" and "delayed healing" for a closed fracture.
• Verify that the patellar fracture type and laterality are truly unspecified in the medical record.
• Do not use this code for initial encounters or for fractures that are healing normally.
