Nondisp osteochon fx unsp patella, init for opn fx type I/2

This code signifies a fracture involving both the cartilage and underlying bone of the kneecap, where the bone fragments remain in their normal anatomical position. The injury is an open fracture, meaning there is a break in the skin communicating with the fracture site, classified as Type I or Type II according to the Gustilo-Anderson classification.

Apply this code for the initial treatment of a patient presenting with an osteochondral fracture of the patella that is documented as nondisplaced and open, specifically Gustilo Type I or II. This code is appropriate when the specific patella (left or right) is not documented.

• Ensure documentation specifies "nondisplaced" and "osteochondral" for accurate code assignment.
• Confirm the fracture is explicitly documented as an "open fracture type I or II" and represents the initial encounter for treatment.
• If the laterality of the patella is known, a more specific code should be used (e.g., S82.011B, S82.012B).
