Inj msl/fasc/tnd posterior grp at thi lev, left thigh, init

This code signifies an injury, other than a strain or tear, to the muscles, fascia, or tendons located in the posterior (back) compartment of the left thigh. This could include contusions, avulsions, or other specified trauma affecting the hamstring group or associated structures. The "initial encounter" designation indicates the patient is receiving active treatment for this specific injury.

Apply this code for patients presenting with a newly diagnosed injury to the left posterior thigh muscles, fascia, or tendons that is not classified as a simple strain or complete tear. Examples include a direct impact causing a contusion to the hamstring, or an avulsion injury of a hamstring tendon from its attachment point. This code is appropriate when the patient is first seen for the injury and is undergoing diagnostic workup or initial treatment.

• Ensure documentation clearly specifies the type of injury if not a strain or tear (e.g., contusion, avulsion).
• Verify the injury location is definitively the posterior muscle group of the left thigh.
• Confirm this is the patient's initial encounter for active treatment of this specific injury.
