Strain of musc/tend at lower leg level, left leg, subs

This code signifies a non-traumatic injury to a muscle or tendon in the left lower leg, excluding the Achilles tendon, that is currently under active treatment or healing. It indicates a stretching or tearing of muscle fibers or tendon tissue, resulting in pain, swelling, and impaired function.

Apply this code when documenting follow-up care for a patient with a previously diagnosed strain of a muscle or tendon in the left lower leg (e.g., tibialis anterior, gastrocnemius, soleus, peroneal muscles). This includes encounters for physical therapy, re-evaluation of symptoms, medication management, or monitoring of recovery progress after the initial injury.

• Ensure the documentation clearly specifies "left leg" and a "subsequent encounter" for treatment of the strain.
• Distinguish from initial encounter codes (A) and sequela codes (S) based on the patient's current phase of care.
• Confirm the strain is not of the Achilles tendon, as that has a more specific code.
