ICD-10-PCS Code For Pelvic Region: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BW4G includes procedures performed to image anatomy and flow information in the pelvic region using ultrasonography. These ICD-10-PCS codes are used for inpatient documentation when real-time display ultrasonography of pelvic anatomy or blood flow is performed for diagnostic or intra-procedural guidance. Accurate coding within the ICD-10-PCS BW4G group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Pelvic Region Ultrasonography Procedure Overview

This procedure group includes real-time display imaging procedures that use reflected high-frequency sound waves to visualize anatomy and flow information in the pelvic region. These ultrasonography procedures target the anatomical regions of the pelvis and surrounding structures. Accurate coding of these imaging procedures is important for inpatient reimbursement because it documents the diagnostic imaging performed and supports appropriate case mix assignment and payment.

BW4GZZZ	Ultrasonography of Pelvic Region

Typical Clinical Scenarios

A 28-year-old pregnant woman is admitted for evaluation of acute-onset pelvic pain and suspected ovarian torsion. Bedside real-time ultrasonography is performed to visualize pelvic anatomy and assess blood flow to adnexal structures to guide urgent surgical decision-making. The imaging is documented as ultrasonography of the pelvic region performed during the inpatient encounter. Typical codes: BW4GZZZ
A 45-year-old woman is admitted electively for inpatient diagnostic workup of chronic pelvic pain and suspected uterine fibroids after outpatient imaging was inconclusive. Real-time ultrasonography of the pelvic region is performed to characterize pelvic anatomy and evaluate blood flow patterns to aid diagnosis and planning of further management. The procedure is documented in the inpatient record as ultrasonography of the pelvic region. Typical codes: BW4GZZZ
A 60-year-old man develops postoperative pelvic fluid collection with fever following pelvic surgery and is readmitted for evaluation. Inpatient real-time ultrasonography of the pelvic region is used to localize the collection and assess surrounding anatomy and vascular flow before image-guided drainage or further intervention. The imaging is recorded as ultrasonography of the pelvic region in the inpatient chart. Typical codes: BW4GZZZ
