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

This code signifies an open fracture of the left patella, not otherwise specified as a transverse, stellate, or longitudinal type. The "open" nature indicates a break in the skin communicating with the fracture site, specifically classified as a Gustilo-Anderson Type IIIA, IIIB, or IIIC. This code is used for the initial treatment of such an injury.

Apply this code when documenting the initial encounter for a patient presenting with an open fracture of the left patella that does not fit more specific patellar fracture types. This would include cases where the fracture is comminuted, segmental, or otherwise unclassifiable beyond its open nature and location.

• Ensure documentation clearly specifies "left" patella and an "open" fracture type IIIA, IIIB, or IIIC.
• Confirm this is the patient's initial encounter for this specific injury; subsequent care will require different encounter codes.
• Do not use this code for closed fractures or open fractures of other patellar types (e.g., transverse, stellate).
