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

This code signifies a follow-up visit for a patient who sustained an open fracture of the left patella, specifically a Type I or Type II open fracture, and is currently experiencing routine healing. It indicates that the initial injury involved a break in the skin communicating with the fracture site, and the healing process is proceeding as expected without complications.

Use this code for subsequent encounters where a patient with a previously diagnosed open Type I or Type II left patellar fracture is being monitored for routine healing. This would include office visits, follow-up imaging, or physical therapy sessions during the uncomplicated recovery phase. It is appropriate when the fracture is not yet fully healed but is progressing normally.

• Ensure documentation clearly specifies "left patella" and "open fracture type I or II" from the initial injury.
• Verify that the encounter is for a "subsequent encounter" and that healing is described as "routine" or "uncomplicated."
• Do not use this code for initial injury encounters or for encounters involving delayed healing, nonunion, or malunion.
