Patient presents with complaints of right wrist pain and swelling following a fall on an outstretched hand.  Onset of symptoms occurred approximately two days ago.  Patient reports pain is exacerbated by movement and describes it as sharp and aching.  Physical examination reveals tenderness to palpation over the lateral aspect of the right wrist, mild edema, and ecchymosis.  Range of motion is limited due to pain, particularly with extension and radial deviation.  No crepitus or obvious deformity noted.  Neurovascular examination of the hand is intact.  Given the mechanism of injury, clinical presentation, and physical exam findings, the diagnosis of right wrist sprain is made.  Differential diagnoses considered include fracture, tendonitis, and ligament tear.  Radiographs of the right wrist were obtained to rule out fracture and are negative for acute bony abnormality.  Treatment plan includes RICE therapy (rest, ice, compression, elevation), NSAIDs for pain management, and a right wrist splint for immobilization.  Patient education provided regarding activity modification and follow-up care.  Follow-up scheduled in one week to assess symptom improvement and discuss potential physical therapy referral if indicated.  ICD-10 code S63.501A, right wrist sprain, initial encounter, is assigned.
