ICD-10-PCS Code For Chest Wall: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BH4B includes procedures performed to image structures in the chest wall. These ICD-10-PCS codes are used for inpatient documentation when real-time ultrasonography is performed to evaluate chest wall anatomy, masses, fluid collections, or related flow information. Accurate coding within the ICD-10-PCS BH4B group is essential for proper inpatient reimbursement, as it captures the diagnostic imaging procedure performed and supports clinical documentation accuracy.

Chest Wall Ultrasonography Procedure Overview

This procedure group includes real-time display ultrasonography procedures that capture reflected high-frequency sound waves to generate images of the chest wall. These procedures target the Skin, Subcutaneous Tissue and Breast body system and are used to visualize anatomy and flow information of the chest wall. Accurate ICD-10-PCS coding of these ultrasonography procedures is important for inpatient reimbursement and for reflecting the diagnostic imaging services provided during a hospital stay.

When to Use

Use a code from this group when a real-time ultrasonography exam is performed specifically on the chest wall to assess anatomy, masses, fluid collections, or vascular flow. These codes apply for inpatient documentation of diagnostic imaging procedures directed at the chest wall within the Skin, Subcutaneous Tissue and Breast body system.

ICD-10-PCS Code	Description
BH4BZZZ	Ultrasonography of Chest Wall

Typical Clinical Scenarios

An elderly patient is admitted with acute swelling, localized pain, and erythema over the anterior chest after blunt trauma; concern for a hematoma, soft-tissue tear, or developing abscess prompts inpatient bedside imaging to evaluate the chest wall layers and fluid collections. Real-time ultrasonography is performed to differentiate hematoma versus abscess and to guide potential percutaneous drainage decisions. Typical codes: BH4BZZZ
A middle-aged patient with a known breast cancer recurrence presents for inpatient assessment of a new palpable mass along the lateral chest wall adjacent to prior surgery and radiation; the goal is to characterize the mass, assess involvement of skin and subcutaneous tissue, and evaluate for suspicious vascularity. A diagnostic chest wall ultrasonography study is used to localize the lesion and inform surgical or oncologic planning. Typical codes: BH4BZZZ
A postoperative patient on the ward develops increasing drainage and localized fluctuance at a chest wall surgical incision site concerning for postoperative fluid collection or seroma; real-time ultrasound is performed to confirm the presence and extent of the collection and to assist in ultrasound-guided bedside aspiration if indicated. Typical codes: BH4BZZZ
