ICD-10-PCS Code For Heart: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group C22Y includes procedures performed to image cardiac structures using tomographic nuclear medicine techniques in the heart. These ICD-10-PCS codes are used for inpatient documentation when three-dimensional nuclear medicine imaging of the heart is performed after introduction of a radionuclide. Accurate coding within the ICD-10-PCS C22Y group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Heart Tomographic Procedure Overview

This procedure group includes tomographic nuclear medicine imaging procedures that capture three-dimensional images of the heart by introducing radionuclides and detecting emitted radiation. The procedures target the heart within the Nuclear Medicine section and are used to visualize cardiac structure and function. Accurate ICD-10-PCS coding of these tomographic imaging procedures ensures inpatient records reflect the specific imaging modality performed and supports correct case mix classification and payment.

When to Use

Use a code from this group when a tomographic nuclear medicine imaging study of the heart is performed with introduction of a radionuclide for three-dimensional image reconstruction. Do not use these codes for non-tomographic nuclear medicine studies or imaging of other body systems.

ICD-10-PCS Code	Description
C22YYZZ	Tomographic (Tomo) Nuclear Medicine Imaging of Heart using Other Radionuclide

Typical Clinical Scenarios

An elderly patient is admitted with acute chest pain and nondiagnostic ECG changes; troponin is equivocal and the inpatient team requires three-dimensional assessment of myocardial perfusion to evaluate for ischemia. A tomographic nuclear medicine study of the heart using a nonstandard radionuclide is performed to localize perfusion defects and guide urgent management decisions. The imaging targets the heart and uses tomographic acquisition after introduction of the radionuclide to generate 3D images. Typical codes: C22YYZZ
A middle-aged patient scheduled for inpatient evaluation of complex coronary artery disease undergoes preoperative functional assessment of the myocardium to plan revascularization. The cardiac imaging team performs tomographic nuclear medicine imaging with an alternative radionuclide to obtain three-dimensional perfusion and viability information while the patient is admitted for planned diagnostic workup. The procedure focuses on the heart and uses tomographic techniques after radionuclide administration. Typical codes: C22YYZZ
A hospitalized patient with prior inconclusive planar cardiac nuclear studies requires repeat, more detailed three-dimensional imaging to clarify persistent regional wall motion abnormalities and guide further therapy. The nuclear medicine service administers an alternative radionuclide and performs tomographic imaging of the heart to improve spatial resolution and characterization of the previously indeterminate findings. This repeat inpatient study targets the heart and employs tomographic acquisition following radionuclide introduction. Typical codes: C22YYZZ
