Left Breast Ultrasonography Procedure Overview

This procedure group covers real-time ultrasonography imaging of the left breast using reflected high-frequency sound waves. Procedures in this group target the skin, subcutaneous tissue, and breast and provide dynamic images of breast anatomy and blood flow when applicable. Accurate coding is important for inpatient reimbursement because it ensures the recorded procedure matches clinical documentation and supports appropriate case mix assignment.

ICD-10-PCS Code	Description
BH41ZZZ	Ultrasonography of Left Breast

Typical Clinical Scenarios

A woman admitted for evaluation of an acute, enlarging painful left breast mass with overlying skin erythema and concern for abscess or complicated mastitis; inpatient workup requires real-time imaging to distinguish fluid collection from cellulitis and guide potential percutaneous drainage planning. A left-breast diagnostic ultrasound is performed at bedside to characterize the lesion and assess vascularity. Typical codes: BH41ZZZ
A patient hospitalized for staging and preoperative planning after core-needle biopsy showed suspicious left breast findings; inpatient imaging is needed to localize multifocal lesions and assess extent before definitive surgery. Real-time left breast ultrasonography is used to map lesions and correlate with prior biopsy sites to guide surgical planning. Typical codes: BH41ZZZ
An elderly patient with acute postoperative concern following left breast-conserving surgery who develops a palpable fluid collection and increased drainage; inpatient clinicians obtain point-of-care left breast ultrasound to evaluate for seroma versus hematoma and to determine if image-guided aspiration is appropriate. Typical codes: BH41ZZZ
