Typical Clinical Scenarios

A 45-year-old woman presents to the emergency department with rapidly increasing pain, swelling, erythema, and fluctuance in the left upper arm after a puncture wound. Imaging and exam confirm a sizable intramuscular abscess within the left biceps muscle requiring urgent evacuation; the surgeon performs an open incision and places a drain to ensure continued postoperative drainage. An open approach with a drainage device is chosen because of the abscess size, tissue necrosis risk, and need for continued postoperative drainage. Typical codes: 0K9800Z
A 60-year-old diabetic patient is admitted for scheduled operative management of a chronic, fluctuant seroma within the left triceps muscle that failed repeated needle aspirations in clinic. In the operating room, the surgeon performs a planned percutaneous endoscopic drainage to visualize and evacuate the collection and to break loculations under direct vision. The minimally invasive percutaneous endoscopic approach is chosen to limit soft-tissue disruption while allowing thorough internal drainage. Typical codes: 0K9840Z
A 28-year-old man returns to the hospital several days after blunt trauma to the left upper arm with a previously treated intramuscular hematoma that has reaccumulated and is causing persistent pain and limited range of motion. Because prior conservative measures and outpatient needle drainage were unsuccessful, the team performs a percutaneous drainage without placement of an indwelling device to evacuate the recurrent collection and obtain fluid for culture. The percutaneous, non-device drainage technique addresses the complication of reaccumulation while avoiding a new open incision. Typical codes: 0K983ZZ
