Strain of musc/fasc/tend long head of biceps, left arm, subs

This code signifies a non-traumatic injury to the long head of the biceps muscle, its surrounding fascia, or its tendon in the left arm, specifically when the patient is receiving active treatment after the initial phase of injury. This typically involves an overstretching or tearing of these soft tissues, leading to pain and functional impairment.

Apply this code for follow-up visits, rehabilitation sessions, or subsequent evaluations of a left biceps long head strain. This includes scenarios where the patient is undergoing physical therapy, receiving injections, or being monitored for healing progression after the initial diagnosis.

• Ensure documentation specifies the left arm and the long head of the biceps.
• Confirm the encounter is for active treatment or follow-up, not the initial injury.
• Distinguish from sprains (ligamentous injury) or complete tears, which have different codes.
