BH4CZZZ	Ultrasonography of Head and Neck

Typical Clinical Scenarios

An elderly patient admitted for cellulitis with a fluctuating tender mass in the submandibular region. Bedside real-time ultrasonography is performed to evaluate the skin and subcutaneous tissue of the neck to distinguish a localized abscess from cellulitis and to guide decisions about drainage versus continued medical therapy. The study focuses on superficial soft tissue structures of the head and neck and documents real-time images of the abnormality. Typical codes: BH4CZZZ
A middle-aged woman admitted for inpatient evaluation of a palpable lateral neck mass found on outpatient exam; the team plans diagnostic workup while monitoring for biopsy. Real-time ultrasonography of the skin and subcutaneous tissues of the head and neck is performed to characterize the lesion, assess its relationship to superficial structures, and help target an ultrasound-guided core biopsy if indicated. Typical codes: BH4CZZZ
A postoperative patient develops a tender, erythematous area at a recent superficial neck incision site with concern for a postoperative fluid collection. Bedside real-time ultrasonography of the superficial head and neck tissues is used to identify and localize a seroma or hematoma in the subcutaneous tissue to guide percutaneous aspiration or drainage. Typical codes: BH4CZZZ
