Patient presents with complaints of shoulder pain, stiffness, and limited range of motion, consistent with symptoms of shoulder osteoarthritis.  Onset of symptoms was gradual, reported as [duration] ago, and is exacerbated by activity and relieved by rest.  Patient reports difficulty with [specific activities of daily living affected, e.g., reaching overhead, dressing, sleeping].  Physical examination reveals crepitus on shoulder movement, tenderness to palpation of the glenohumeral joint, and reduced active and passive range of motion in [specify planes, e.g., flexion, abduction, external rotation].  Radiographic imaging of the shoulder demonstrates joint space narrowing, osteophyte formation, and subchondral sclerosis, confirming the diagnosis of osteoarthritis of the shoulder.  Differential diagnosis includes rotator cuff tear, adhesive capsulitis, and glenohumeral instability.  Assessment: Primary diagnosis: Osteoarthritis of the shoulder (ICD-10 code: M19.01).  Treatment plan includes conservative management with nonsteroidal anti-inflammatory drugs (NSAIDs) for pain management, physical therapy for range of motion improvement and strengthening exercises, and patient education on activity modification.  Referral to orthopedics for consideration of intra-articular corticosteroid injections or surgical intervention, such as shoulder arthroplasty, if conservative treatment fails.  Follow-up scheduled in [timeframe] to assess response to treatment and adjust plan as needed.
