Nondisp subtrochnt fx l femur, init for opn fx type 3A/B/C

This code signifies a break in the upper part of the left thigh bone, specifically below the lesser trochanter, where the bone fragments are still in their normal alignment. The fracture is open, meaning the bone has broken through the skin, and is classified as a severe type (IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification system. This is the first time the patient is receiving treatment for this specific injury.

Use this code for a patient presenting with a newly diagnosed, non-displaced subtrochanteric fracture of the left femur that has an associated open wound exposing the bone. This applies to initial treatment encounters for severe open fractures, such as those with extensive soft tissue damage, periosteal stripping, or arterial injury.

• Ensure documentation clearly specifies "nondisplaced" and "left femur."
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) for the open fracture.
• Confirm this is the initial encounter for treatment of this specific fracture.
