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

This code indicates a fracture of the left kneecap, other than a transverse, comminuted, or unspecified type, that is currently in the healing phase but is taking longer than expected. The fracture is not open to the environment.

Apply this code when a patient presents for follow-up care of a left patellar fracture that was initially treated as closed, and the physician documents delayed healing. This is appropriate for subsequent visits after the initial treatment, where the fracture has not yet fully united.

• Ensure documentation specifies "left" patella and "other" fracture type.
• Verify the encounter is for a subsequent visit and that delayed healing is explicitly noted.
• Do not use for initial treatment or for fractures that are healing normally or nonunion.
