ICD-10-PCS Code For Digestive System: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CD1Y includes procedures performed to image structures in the digestive system using planar nuclear medicine techniques. These ICD-10-PCS codes are used for inpatient documentation when single plane radionuclide imaging of the gastrointestinal tract or related digestive organs is performed. Accurate coding within the ICD-10-PCS CD1Y group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Digestive System Planar Nuclear Medicine Imaging Procedure Overview

This procedure group includes planar nuclear medicine imaging studies that involve introduction of radioactive materials to visualize the digestive system. These procedures capture single plane images developed from the capture of radioactive emissions within the gastrointestinal tract and related digestive organs. Accurate coding of these inpatient procedures ensures appropriate documentation of the imaging performed and supports correct assignment of case mix and payment.

When to Use

Use a code from this group when a planar radionuclide imaging study of the digestive system is performed with introduction of radioactive materials for image acquisition. These codes apply when single plane imaging is obtained to evaluate function or structure of the gastrointestinal tract during an inpatient encounter.

CD1YYZZ	Planar Nuclear Medicine Imaging of Digestive System using Other Radionuclide

Typical Clinical Scenarios

A hospitalized elderly patient with active upper gastrointestinal bleeding and unclear source after endoscopy is being monitored for ongoing blood loss and suspected intermittent hemorrhage from the stomach; clinicians order a planar nuclear medicine scan to detect and localize radionuclide-labeled red blood cell pooling within the digestive tract to guide further management while inpatient. Typical codes: CD1YYZZ
An inpatient with chronic suspected gastrointestinal motility disorder (severe gastroparesis) admitted for worsening nutritional failure and frequent vomiting undergoes a single-plane radionuclide study using a nonstandard tracer to assess gastric emptying and functional transit of the digestive system as part of the diagnostic workup. Typical codes: CD1YYZZ
A postoperative patient in the hospital after complex abdominal surgery develops unexplained persistent abdominal pain and low-grade bleeding; to evaluate for localized leakage or slow hemorrhage into the digestive tract without immediate endoscopic access, a planar radionuclide imaging study using an alternative radiotracer is performed to capture single-plane images of the gastrointestinal tract. Typical codes: CD1YYZZ
