Clinical & Coding Specifications
Clinical Context
A 42-year-old patient presents to the emergency department with progressive swelling, erythema, and throbbing pain localized to the lateral ankle for 24–48 hours after sustaining a minor puncture injury. On examination there is focal fluctuance, warmth, and tenderness over the lateral malleolar area with limited ankle range of motion from pain. Vital signs show low-grade fever and elevated white blood cell count. The treating physician determines that the collection is an abscess requiring incision and drainage. The procedure is performed under local anesthesia in a procedure room or emergency department treatment area. The provider prepares the skin with antiseptic, administers local infiltration anesthesia, makes an incision over the fluctuance, expresses purulent material, explores and breaks loculations, irrigates the cavity, obtains culture specimens as indicated, and places packing or a small drain when clinically required. Post-procedure care includes wound packing changes, tetanus prophylaxis if indicated, wound culture-directed antibiotics, and instructions for return precautions and follow-up with the treating clinician or surgical service if systemic signs persist.
