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

This code signifies a fracture of the patella (kneecap) that is not specifically classified as a transverse, comminuted, or other named type, and the precise location on the patella is not documented. It indicates an initial encounter for an open fracture where the bone protrudes through the skin, categorized as a severe type IIIA, IIIB, or IIIC injury.

Use this code for a patient presenting with a newly diagnosed, unspecified patellar fracture that is open and classified as Gustilo-Anderson type IIIA, IIIB, or IIIC. This applies when the specific fracture pattern (e.g., transverse, comminuted) is not detailed in the medical record.

• Ensure the documentation clearly specifies an "open" fracture and the Gustilo-Anderson classification (IIIA, IIIB, or IIIC).
• Only use this code for the initial encounter for treatment of the fracture.
• If a more specific patellar fracture type (e.g., transverse, comminuted) is documented, a more precise code should be selected.
