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 CD2Y includes procedures performed to image internal structures in the digestive system using tomographic nuclear medicine techniques. These ICD-10-PCS codes are used for inpatient documentation when three-dimensional nuclear medicine imaging of the gastrointestinal tract is performed using introduced radionuclides. Accurate coding within the ICD-10-PCS CD2Y group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Digestive System Tomographic Nuclear Medicine Imaging Procedure Overview

This procedure group includes tomographic nuclear medicine imaging studies that introduce radioactive materials to produce three-dimensional images of the digestive system. These examinations target the gastrointestinal system and involve capturing radioactive emissions to create cross-sectional displays for diagnostic evaluation. Accurate coding of these inpatient procedures ensures the clinical imaging performed is reflected correctly for reimbursement and case-mix assignment.

D	Body System	Gastrointestinal System
2	Operation	Tomographic (Tomo) Nuclear Medicine Imaging
Y	Body Part	Digestive System

When to Use

Use a code from this group when radioactive material is introduced for tomographic nuclear medicine imaging to evaluate anatomy or function of the digestive system during an inpatient stay. Select these codes when the procedure produces three-dimensional displays reconstructed from captured radioactive emissions of the gastrointestinal tract.

ICD-10-PCS Code	Description
CD2YYZZ	Tomographic (Tomo) Nuclear Medicine Imaging of Digestive System using Other Radionuclide

Typical Clinical Scenarios

An elderly inpatient with subacute, unexplained gastrointestinal bleeding and hemodynamic instability after negative endoscopic and angiographic evaluations is admitted for further localization of the bleeding source and assessment of bowel perfusion; tomographic nuclear medicine imaging is performed after introduction of a radionuclide tracer to generate three-dimensional images of the digestive tract to help localize intermittent bleeding and guide surgical or interventional planning. Typical codes: CD2YYZZ
A hospitalized patient with complex post-operative abdominal pain and suspected delayed gastric emptying after major abdominal surgery is evaluated because oral contrast studies are inconclusive; a tomographic nuclear medicine study using an introduced radionuclide tracer is performed to obtain three-dimensional functional imaging of the digestive system to quantify transit and identify an anatomic or functional cause. Typical codes: CD2YYZZ
An inpatient with known neurogenic bowel and worsening malabsorption is admitted for diagnostic workup to distinguish small-bowel bacterial overgrowth from gut dysmotility; a tomographic nuclear medicine imaging procedure is used with an injected radionuclide to produce three-dimensional images of gastrointestinal transit and segmental function to inform medical management. Typical codes: CD2YYZZ
