Patient presents with symptoms consistent with trigger finger, also known as stenosing tenosynovitis.  The patient reports catching, clicking, or locking of the affected finger (specify finger: thumb, index, middle, ring, or small), often worse in the morning.  Stiffness and pain at the base of the finger are noted, specifically at the level of the A1 pulley.  The patient may describe difficulty straightening or bending the finger, and sometimes a popping or snapping sensation is felt during movement.  On physical examination, palpable tenderness andor a nodule may be present at the A1 pulley.  The affected finger may demonstrate triggering, locking, or catching during flexion and extension.  Differential diagnosis includes Dupuytren's contracture, flexor tendonitis, and arthritis.  Assessment confirms the diagnosis of trigger finger (ICD-10 code M65.3), specifying laterality (right or left) and digit involved.  Treatment plan may include conservative management with rest, splinting, nonsteroidal anti-inflammatory drugs (NSAIDs), and corticosteroid injections.  Surgical intervention, such as trigger finger release (CPT code 26055), may be considered if conservative measures fail to provide adequate relief.  Patient education provided on activity modification, splinting techniques, and potential complications. Follow-up scheduled to assess treatment response and adjust plan as needed.
