Strain of unsp musc/fasc/tend at thi lev, left thigh, subs

This code signifies a muscle, fascia, or tendon strain in the left thigh where the specific muscle group involved is not documented. It indicates that the patient is receiving follow-up care for this injury, such as during rehabilitation or subsequent office visits after the initial treatment.

Apply this code for left thigh muscle, fascia, or tendon strains when the specific anatomical site (e.g., quadriceps, hamstrings, adductors) is not specified in the medical record, and the encounter is for ongoing treatment or recovery. This is appropriate for follow-up appointments after the initial diagnosis and treatment have been established.

• Ensure documentation clearly indicates the left thigh and that the encounter is subsequent.
• Avoid using this code if a more specific muscle group or tendon is identified in the documentation.
• Pair with an external cause code (V00-Y99) if the cause of the injury is known and documented.
