Typical Clinical Scenarios

An adult patient presents to the emergency department with rapidly increasing left-sided neck swelling, fever, and sepsis signs after a recent skin infection; imaging demonstrates a left cervical lymphatic abscess with mass effect and systemic toxicity, prompting urgent inpatient drainage to control infection and source. Typical codes: 07923ZZ, 079240Z
A scheduled inpatient admission for a patient with chronic, recurrent chylous leakage into the left neck after prior neck dissection causing a persistent lymphatic collection; the team plans a percutaneous endoscopic drainage and placement of a drain to evacuate lymph and allow definitive healing. Typical codes: 079240Z, 07923Z
A hospitalized immunocompromised patient develops a small left neck lymphatic fluid collection identified on ultrasound during evaluation of persistent fever; diagnostic percutaneous aspiration is performed to obtain fluid for culture and cytology to guide treatment. Typical codes: 07923ZX, 07924ZX
