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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CD17 includes procedures performed to introduce radioactive materials for planar nuclear medicine imaging in the gastrointestinal tract. These ICD-10-PCS codes are used for inpatient documentation when a radiopharmaceutical is administered to obtain single plane images of gastrointestinal structure or function. Accurate coding within the ICD-10-PCS CD17 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Gastrointestinal Tract Planar Nuclear Medicine Imaging Procedure Overview

These procedures involve introduction of radioactive materials into the body to capture single plane images of the gastrointestinal tract using planar nuclear medicine techniques. They target the gastrointestinal system and use radiopharmaceuticals to visualize function or anatomy based on emitted radiation. Accurate ICD-10-PCS coding ensures inpatient records reflect the specific nuclear medicine imaging performed, which affects clinical documentation and reimbursement.

When to Use

Use a code from this group when a radiopharmaceutical is administered specifically to image the gastrointestinal tract with single plane planar nuclear medicine techniques. Do not use these codes for non-nuclear imaging modalities or for multi-planar or tomographic nuclear imaging procedures.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
CD171ZZ	Planar Nuclear Medicine Imaging of Gastrointestinal Tract using Technetium 99m (Tc-99m)
CD17DZZ	Planar Nuclear Medicine Imaging of Gastrointestinal Tract using Indium 111 (In-111)
CD17YZZ	Planar Nuclear Medicine Imaging of Gastrointestinal Tract using Other Radionuclide

Typical Clinical Scenarios

A hospitalized elderly patient with chronic iron deficiency anemia and intermittent melena undergoes evaluation after multiple negative endoscopies; the clinical team admits the patient for inpatient localization of a suspected slow gastrointestinal bleed to guide further targeted endoscopic or surgical intervention. A radiopharmaceutical is administered for single‑plane planar imaging to detect active bleeding in the gastrointestinal tract. Typical codes: CD171ZZ, CD17YZZ
A middle‑aged patient admitted from the emergency department with refractory nausea and suspected delayed gastric emptying after recent abdominal surgery; inpatient nuclear medicine is requested to assess gastric transit and motility using a radiotracer to obtain planar images of gastrointestinal function. The procedure involves introduction of a radionuclide to visualize gastric emptying on single‑plane imaging. Typical codes: CD171ZZ, CD17YZZ
An oncology patient inpatient for staging and management of suspected gastrointestinal mucosal bleeding related to tumor invasion, where localization of the bleed source is needed urgently to plan embolization or endoscopic therapy; a radiopharmaceutical planar study is performed to capture single‑plane images of the gastrointestinal tract emissions for localization. Typical codes: CD17DZZ, CD17YZZ
