Oth fracture of left patella, subs for clos fx w nonunion

This code signifies a fracture of the left kneecap, specifically one that is not a transverse, comminuted, or unspecified type, and has failed to heal properly. The patient is in a follow-up phase of care for this unhealed, closed fracture.

This code is appropriate for documenting ongoing management of a left patellar fracture that has not united, after the initial treatment phase. It would be used when a patient presents for evaluation, treatment, or monitoring of a nonunion of a closed left patella fracture.

• Ensure documentation clearly states "nonunion" and specifies the left patella.
• Verify the encounter is subsequent to the initial fracture treatment.
• Confirm the fracture is closed; if open, a different code would be necessary.
