Sprain of left rotator cuff capsule, initial encounter

This code signifies a sprain or tear affecting the fibrous capsule surrounding the left shoulder's rotator cuff muscles. This injury typically involves overstretching or tearing of the ligaments and connective tissues that stabilize the glenohumeral joint. Patients often experience pain, limited range of motion, and weakness in the affected shoulder.

Apply this code for a newly diagnosed sprain of the left rotator cuff capsule, such as after an acute injury like a fall onto an outstretched arm or a sudden, forceful movement. It is appropriate for the initial evaluation and treatment phase of this specific shoulder injury.

• Ensure documentation specifies "left" shoulder and "rotator cuff capsule" involvement.
• Confirm this is the patient's initial encounter for this specific injury, not a follow-up or sequela.
• Distinguish from rotator cuff muscle/tendon tears (S46.-) or other shoulder sprains (S43.9-).
