ICD-10-PCS Code For Rectum: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BD4C includes procedures performed to image structures in the rectum. These ICD-10-PCS codes are used for inpatient documentation when real-time ultrasound imaging of rectal anatomy or flow information is performed for diagnostic evaluation or procedural guidance. Accurate coding within the ICD-10-PCS BD4C group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Rectum Ultrasonography Procedure Overview

This code group covers real-time ultrasonographic imaging of the rectum, capturing reflected high-frequency sound waves to display anatomy and flow information of the gastrointestinal system. Procedures involve using ultrasound transducers to visualize rectal wall layers, surrounding tissues, and vascular flow for diagnostic and procedural guidance. Accurate ICD-10-PCS coding ensures inpatient records reflect the imaging performed and supports appropriate case mix and payment.

ICD-10-PCS Code	Description
BD4CZZZ	Ultrasonography of Rectum

Typical Clinical Scenarios

An adult patient is admitted with acute rectal pain, rectal bleeding, and suspicion for a perirectal abscess or deep mucosal tear after trauma; inpatient evaluation includes bedside endorectal ultrasound to visualize rectal wall layers, detect fluid collections, and guide potential drainage planning. Typical codes: BD4CZZZ
An elective inpatient admission for staging of newly diagnosed rectal cancer where high-resolution endorectal ultrasonography is performed preoperatively to assess depth of tumor invasion and relationship to sphincter complex, informing surgical planning and neoadjuvant therapy decisions. Typical codes: BD4CZZZ
A hospitalized patient with worsening fecal incontinence after prior pelvic surgery undergoes dynamic endorectal ultrasound to evaluate sphincter integrity, identify postoperative defects, and guide decisions about further reconstructive procedures. Typical codes: BD4CZZZ
