Strain extensor musc/fasc/tend r idx fngr at forarm lv, subs

This code signifies a muscle strain affecting the extensor structures of the right index finger, specifically at the forearm level. It indicates damage to the muscle, its surrounding fascia, or the tendon that extends the index finger, occurring during the recovery phase of the injury.

Apply this code when documenting follow-up care for a patient previously diagnosed with a strain of the right index finger extensor mechanism at the forearm. This includes scenarios such as subsequent office visits for physical therapy, wound care, or re-evaluation of healing progress after the initial injury.

• Ensure documentation specifies the right index finger and the forearm level involvement.
• Confirm the encounter is for subsequent care, not the initial treatment of the injury.
• Distinguish from sprains (ligamentous injury) or complete tears, which have different codes.
