Strain of musc/tend the rotator cuff of left shoulder, init

This code signifies an acute, non-traumatic overstretching or tearing of the muscle and/or tendon fibers within the rotator cuff of the patient's left shoulder. It indicates an injury that has not progressed to a complete tear and is typically associated with pain, weakness, and limited range of motion in the affected shoulder. The "initial encounter" designation means the patient is receiving active treatment for this specific injury.

Apply this code for patients presenting with a newly diagnosed strain of the left rotator cuff muscles or tendons, such as from overuse, sudden forceful movement, or minor trauma. This is appropriate when the physician's documentation clearly states a strain and the patient is in the acute phase of treatment, including evaluation, medication management, or initiation of physical therapy. Do not use for chronic conditions or follow-up care.

• Ensure documentation specifies "strain" and not a "tear" (partial or complete), as different codes apply for tears.
• Verify the laterality is clearly documented as "left shoulder."
• Confirm this is the initial encounter for active treatment; subsequent encounters for the same injury will require different seventh characters.
