Patient presents with complaints of left shoulder pain, consistent with a suspected rotator cuff tear.  Symptoms include pain exacerbated by abduction and external rotation, weakness, and limited range of motion.  Onset of pain was reported as [gradual/acute] and began [timeframe] ago, potentially related to [mechanism of injury if applicable, e.g., lifting heavy object, fall].  Patient reports difficulty with activities of daily living such as [specific examples, e.g., reaching overhead, dressing, sleeping].  Physical examination reveals tenderness to palpation over the left anterior and lateral shoulder, positive Neer and Hawkins impingement signs, and weakness with supraspinatus and infraspinatus muscle testing.  Differential diagnosis includes rotator cuff tendinopathy, adhesive capsulitis, and glenohumeral arthritis.  Preliminary diagnosis of left rotator cuff tear is made based on clinical presentation and physical exam findings.  Ordered MRI of the left shoulder to confirm diagnosis and assess the extent of the tear.  Treatment plan includes conservative management with NSAIDs for pain relief, physical therapy for range of motion and strengthening exercises, and activity modification.  Surgical intervention may be considered if conservative treatment fails to provide adequate relief.  Patient education provided regarding rotator cuff injury, recovery expectations, and importance of adherence to the treatment plan. Follow-up scheduled in [timeframe] to reassess symptoms and discuss further management.  ICD-10 code M75.111 (Rotator cuff tear or rupture, left shoulder, complete) or M75.112 (Rotator cuff tear or rupture, left shoulder, incomplete) will be confirmed upon imaging results.  CPT codes for evaluation and management, physical therapy, and potential surgical intervention will be documented accordingly.
