Unsp fx r patella, subs for opn fx type 3A/B/C w routn heal

This code describes a right patellar fracture that was initially unspecified regarding its exact type, but is now in a subsequent phase of care. The fracture is an open fracture of severe type (IIIA, IIIB, or IIIC) and is currently healing routinely.

Use this code for follow-up encounters for a patient with a previously diagnosed, unspecified open fracture of the right patella that was classified as Gustilo-Anderson type IIIA, IIIB, or IIIC. This code is appropriate when the fracture is progressing as expected without complications during the healing phase.

• Ensure documentation specifies "subsequent encounter" and "routine healing."
• Verify the initial fracture was an unspecified right patella fracture and an open fracture type IIIA, IIIB, or IIIC.
• Do not use for initial treatment or for encounters involving delayed healing, nonunion, or malunion.
