Oth fracture of right patella, init for opn fx type 3A/B/C

This code signifies an open fracture of the right patella, not otherwise specified as a transverse, stellate, or longitudinal fracture. The "C" suffix indicates an initial encounter for a Gustilo-Anderson Type IIIA, IIIB, or IIIC open fracture, meaning there is significant soft tissue damage and potential for contamination.

Apply this code when documenting the initial treatment of a patient presenting with an open fracture of the right kneecap that does not fit the descriptions for other specified patellar fracture types. This is appropriate for cases requiring surgical debridement and stabilization of the fracture.

• Ensure the documentation clearly specifies an "open" fracture and the right patella.
• Verify this is the initial encounter for treatment; subsequent care will require different seventh characters.
• Confirm the fracture type is not more specifically described (e.g., transverse, stellate) to avoid using a less precise code.
