Unsp fx shaft of left femur, init for opn fx type 3A/B/C

This code signifies an unspecified break in the long, central part of the left thigh bone. The fracture is characterized as an open injury, 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 code is used for the initial treatment of such an injury.

This code is appropriate for documenting the initial encounter for a patient presenting with an open fracture of the shaft of the left femur where the specific fracture pattern (e.g., transverse, oblique) is not yet determined or documented. It is used when the open nature of the injury is clearly described as Gustilo-Anderson type IIIA, IIIB, or IIIC.

• Ensure documentation explicitly states "left femur shaft" and "open fracture type IIIA, IIIB, or IIIC."
• Verify this is the patient's initial encounter for this specific injury.
• If the specific fracture type (e.g., transverse, oblique) is documented, a more specific code should be used.
