Clinical & Coding Specifications
Clinical Context
A middle-aged patient presents to the urgent care clinic with a 48-hour history of progressive pain, swelling, and erythema localized along the flexor aspect of the ring finger after a puncture injury. The finger is held in slight flexion, with tenderness along the flexor tendon sheath, fusiform swelling of the digit, and pain on passive extension. Vital signs show low-grade fever. Point-of-care ultrasound confirms fluid collection tracking within the flexor tendon sheath. The provider obtains informed consent and prepares for drainage of the infected flexor tendon sheath in a minor procedure room under sterile conditions. Local anesthesia is administered with digital and field blocks. A small incision and irrigation are performed to evacuate purulent fluid from the tendon sheath; specimens are sent for gram stain and culture. The wound is dressed and the patient is given post-procedure instructions, analgesia, and a short course of empiric antibiotics. Follow-up is arranged within 24–48 hours for reassessment and potential repeat irrigation if indicated.
