Nondisp fx of unsp tibial spine, init for opn fx type 3A/B/C

This code signifies a break in the tibial spine (a bony prominence on the top of the tibia within the knee joint) that has not shifted from its normal anatomical position. Importantly, the fracture is open, meaning the bone has broken through the skin, and is classified as a severe open fracture type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. This code is used for the initial treatment of such an injury.

Apply this code when documenting the first encounter for a patient presenting with an open, nondisplaced fracture of the tibial spine. This is appropriate when the orthopedic surgeon has classified the open fracture as Gustilo-Anderson type IIIA, IIIB, or IIIC, typically requiring extensive debridement and often reconstructive procedures.

• Ensure documentation clearly specifies "nondisplaced" and "unspecified tibial spine" if the specific location (medial/lateral) is not documented.
• Verify the open fracture classification (IIIA, IIIB, or IIIC) is explicitly stated in the medical record.
• Confirm this is the initial encounter for treatment of this specific injury. Subsequent care will require a different encounter character.
