Typical Clinical Scenarios

An adult presents to the emergency department with a rapidly expanding traumatic hematoma of the upper lip after a facial blunt-force injury, causing pain, cosmetic deformity, and risk of compromised soft-tissue perfusion; the patient is admitted for urgent drainage to evacuate the hematoma and control bleeding from the upper lip soft tissues. Typical codes: 0C900ZZ, 0C903ZZ
A diabetic patient with localized cellulitis of the upper lip develops a fluctuant abscess after failed outpatient antibiotics; due to surrounding tissue edema and systemic signs (fever, leukocytosis), the patient is admitted for incision and drainage of the abscess to remove purulent fluid and obtain cultures. Typical codes: 0C9000Z, 0C90X0Z
A patient hospitalized for anticoagulation complication develops an upper lip subcutaneous hematoma that persists despite conservative measures and requires image-guided percutaneous evacuation to reduce tension and bleeding risk; the procedure is performed percutaneously with placement of a small drainage device for ongoing drainage. Typical codes: 0C9030Z
