Strain of left quadriceps muscle, fascia and tendon, subs

This code signifies a non-traumatic overstretching or tearing of the muscle fibers, fascia, or tendons within the left quadriceps group. It indicates an injury that has already received initial treatment and the patient is now in a healing phase, requiring ongoing care or follow-up.

This code is appropriate for documenting a patient's follow-up visit for a previously diagnosed left quadriceps strain, such as for physical therapy, re-evaluation, or medication management during the recovery period. It should be used after the initial acute treatment phase has concluded.

• Ensure the encounter is for subsequent care, not the initial injury.
• Verify laterality (left) and the specific muscle group (quadriceps).
• Confirm the injury mechanism is a strain, not a tear or rupture requiring a different code.
