Strain of musc/tend at lower leg level, right leg, init

This code signifies a non-traumatic overstretching or tearing of muscle fibers or tendons located in the lower leg, excluding the Achilles tendon, on the right side. It indicates the initial presentation of this injury, meaning the patient is receiving active treatment for a new condition.

Apply this code when a patient presents with a new diagnosis of a muscle or tendon strain in the right lower leg, such as a tibialis anterior strain, peroneal tendon strain, or gastrocnemius strain, that is not an Achilles injury. This is appropriate for the first visit or encounter for this specific injury.

• Ensure documentation specifies "right leg" and "initial encounter" for accurate code assignment.
• Distinguish from Achilles tendon strains (S86.0-) and sprains (S83.-).
• Verify the specific muscle or tendon involved is not the Achilles, as that has a dedicated code.
