ICD-10-PCS Code For Upper Gastrointestinal Tract: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CD15 includes procedures performed to image the upper gastrointestinal tract using planar nuclear medicine techniques. These ICD-10-PCS codes are used for inpatient documentation when single plane nuclear medicine imaging with introduced radioactive materials is performed to evaluate upper gastrointestinal anatomy or function. Accurate coding within the ICD-10-PCS CD15 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Upper Gastrointestinal Tract Planar Nuclear Medicine Imaging Procedure Overview

Procedures in this group involve introduction of radioactive materials and capture of emitted radiation to produce single plane images of the upper gastrointestinal tract. These nuclear medicine studies target the gastrointestinal system to evaluate anatomy and function using radionuclide imaging. Accurate ICD-10-PCS coding ensures inpatient documentation reflects the exact imaging procedure performed and supports correct case mix assignment and reimbursement.

When to Use

Use codes from this group when a patient undergoes inpatient planar nuclear medicine imaging of the upper gastrointestinal tract with introduction of radioactive material. These codes apply when the procedure specifically involves radionuclide administration and single plane image acquisition for diagnostic evaluation of the gastrointestinal system.

ICD-10-PCS Code	Description
CD151ZZ	Planar Nuclear Medicine Imaging of Upper Gastrointestinal Tract using Technetium 99m (Tc-99m)
CD15DZZ	Planar Nuclear Medicine Imaging of Upper Gastrointestinal Tract using Indium 111 (In-111)
CD15YZZ	Planar Nuclear Medicine Imaging of Upper Gastrointestinal Tract using Other Radionuclide

Typical Clinical Scenarios

An older adult hospitalized with acute upper GI bleeding of unclear source after negative endoscopy; continued bleeding or intermittent melena prompts evaluation of gastric emptying and mucosal transit with radionuclide planar imaging to localize active bleeding or assess functional retention. A technetium-based radiotracer is introduced and single-plane emission images are obtained to guide further management. Typical codes: CD151ZZ
A hospitalized patient with suspected delayed gastric emptying (gastroparesis) complicating long-standing diabetes, admitted for symptom control and nutritional management; inpatient planar nuclear medicine study is performed to quantify gastric emptying and guide dietary/medication adjustments. The procedure involves administration of a radionuclide-labeled meal and capture of single-plane gastric images. Typical codes: CD151ZZ, CD15YZZ
An inpatient with a complex postoperative upper abdominal course after bariatric surgery who develops intermittent upper GI obstruction symptoms and possible anastomotic leak; planar radionuclide imaging using an alternate radionuclide is performed when other imaging is inconclusive to evaluate transit and possible focal radiotracer extravasation. This single-plane nuclear study helps assess functional passage through the proximal GI tract in the acute postoperative setting. Typical codes: CD15DZZ, CD15YZZ
