ICD-10-PCS Code for Abdomen And Pelvis: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CW11 includes procedures performed to introduce radioactive materials into the body for planar nuclear medicine imaging of the abdomen and pelvis. These ICD-10-PCS codes are used for inpatient documentation when radiopharmaceuticals are administered and single-plane images are obtained to evaluate abdominal and pelvic anatomy or function. Accurate coding within the ICD-10-PCS CW11 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy and case mix assignment.

Abdomen And Pelvis Planar Nuclear Medicine Imaging Procedure Overview

This group includes planar nuclear medicine imaging procedures that introduce radioactive materials into the body to capture single-plane images of the abdomen and pelvis. These procedures target the anatomical regions of the abdomen and pelvis and involve administration of radiopharmaceuticals and subsequent image capture of emitted radiation. Accurate ICD-10-PCS coding ensures the inpatient record reflects the imaging performed and supports appropriate case mix assignment and reimbursement.

When to Use

Use a code from this group when a radiopharmaceutical is introduced and planar nuclear medicine imaging is performed specifically for the abdomen and pelvis during an inpatient encounter. Do not select these codes for multi‑plane or tomographic nuclear imaging modalities or for procedures targeting other anatomical regions.

Typical Clinical Scenarios

An elderly patient admitted with unexplained right upper quadrant pain, jaundice, and abnormal liver function tests after a recent hospitalization; clinicians suspect biliary leak or occult hepatic abscess and order planar hepatobiliary imaging with a radiopharmaceutical to evaluate hepatic uptake and biliary excretion dynamics. The inpatient planar nuclear medicine study is performed to visualize abdominal radiotracer distribution and assess hepatobiliary function. Typical codes: CW111ZZ, CW11LZZ
A middle-aged patient hospitalized electively for evaluation of chronic pelvic pain and suspected inflammatory bowel disease with nonspecific CT findings; a targeted planar nuclear medicine scan using a radiotracer is performed to assess pelvic and lower abdominal inflammatory activity or abscess localization when cross-sectional imaging is inconclusive. The planned inpatient planar study helps localize functional abnormalities in the abdomen and pelvis to guide further management. Typical codes: CW11FZZ, CW11SZZ
A postoperative patient in the inpatient unit develops fever and signs concerning for intra‑abdominal sepsis after colorectal surgery; surgeons request a rapid planar nuclear medicine scan with an appropriate radiopharmaceutical to detect focal pelvic or abdominal collections or sites of infection when immediate CT is limited by patient stability. The urgent planar imaging of the abdomen and pelvis is used to detect abnormal radiotracer accumulation indicative of infection or abscess. Typical codes: CW11DZZ, CW11YZZ
