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

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. It indicates an overstretching or tearing of these tissues, typically resulting from overuse or sudden forceful movements.

Apply this code for patients presenting with acute pain, tenderness, and possibly swelling in the anterior aspect of the left shoulder or upper arm, following activities such as lifting, throwing, or repetitive arm movements. This code is appropriate for the initial visit for this specific injury.

• Ensure documentation specifies the left arm and the long head of the biceps.
• Confirm the encounter is the initial treatment for this injury; subsequent encounters will use different seventh characters.
• Distinguish from a biceps tendon rupture, which has a separate code.
