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

This code signifies a fracture of the left kneecap, other than a comminuted or transverse type, that was initially an open fracture (meaning the skin was broken) of either Type I or II severity. The patient is currently in a phase where the fracture is not healing at the expected rate.

This code is appropriate for follow-up encounters where a patient is being treated for a left patella fracture that was initially open (Type I or II) and is now exhibiting delayed union. This includes situations where the physician is monitoring the healing process, adjusting treatment plans due to slow healing, or performing procedures related to the delayed healing of this specific fracture.

• Ensure documentation clearly specifies "other fracture" of the left patella and confirms the initial injury was an open fracture Type I or II.
• Verify that the encounter is for "subsequent" care and that "delayed healing" is explicitly documented.
• Do not use for initial encounters or for fractures that are healing normally or are nonunion.
