Strain of msl/fasc/tnd post grp at thi lev, left thigh, subs

This code signifies a muscle, fascia, or tendon strain affecting the posterior compartment of the left thigh, such as the hamstrings. It indicates that the patient is receiving follow-up care for an injury that has already been initially treated.

Apply this code when documenting a patient's visit for ongoing treatment, rehabilitation, or follow-up after the initial management of a left hamstring strain or other posterior thigh muscle group injury. This includes scenarios where the patient is progressing through physical therapy or has a re-evaluation of the injury.

• Ensure the documentation clearly specifies the left thigh and a posterior muscle group involvement.
• Confirm the encounter is for subsequent care, not the initial treatment of the injury.
• Verify the injury is a strain, not a tear or other more severe injury, which would require a different code.
