Oth fx l patella, subs for opn fx type 3A/B/C w delay heal

This code signifies a fracture of the left kneecap that is not a transverse, comminuted, or longitudinal type, and is currently in a delayed healing phase. The initial injury was an open fracture, meaning the skin was broken, and was classified as a severe type (IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification.

This code is appropriate for follow-up encounters where a patient is receiving ongoing treatment for a previously diagnosed open, severe, non-specific left patella fracture that is not healing as expected. This includes situations where the patient is undergoing rehabilitation, wound care, or further surgical intervention due to the delayed union of the fracture.

• Ensure documentation clearly specifies "other" fracture type and the left side.
• Verify the initial fracture was an open type IIIA, IIIB, or IIIC and that healing is explicitly noted as delayed.
• Always use in conjunction with an external cause code if applicable, and any associated complications.
