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 C23Y includes procedures performed to image radioactive emissions in the heart for three-dimensional display using positron emission tomographic techniques. These ICD-10-PCS codes are used for inpatient documentation when a positron emission tomographic study of the heart is performed following introduction of radionuclide agents to evaluate myocardial perfusion or metabolism. Accurate coding within the ICD-10-PCS C23Y group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Heart Positron Emission Tomographic Imaging Procedure Overview

The procedures in this group involve introduction of radioactive materials and acquisition of three-dimensional images of the heart using positron emission tomographic imaging techniques. These nuclear medicine procedures target the heart and its perfusion and metabolic activity. Accurate ICD-10-PCS coding ensures the inpatient record reflects the imaging performed and supports appropriate reimbursement and case mix assignment.

When to Use

Use a code from this group when a positron emission tomographic study of the heart is performed after introduction of a radionuclide agent for three-dimensional imaging. This applies when the procedure documents capture of simultaneous radioactive emissions for cardiac imaging during the inpatient encounter.

ICD-10-PCS Code	Description
C23YYZZ	Positron Emission Tomographic (PET) Imaging of Heart using Other Radionuclide

Typical Clinical Scenarios

An elderly patient admitted with acute chest pain and elevated cardiac biomarkers but nondiagnostic ECG undergoes inpatient evaluation for suspected acute coronary syndrome; when coronary angiography is deferred or equivocal, a PET study of myocardial perfusion is performed to localize ischemia and guide management during the hospitalization. Typical codes: C23YYZZ
A middle-aged patient with known ischemic cardiomyopathy is admitted for optimization of medical therapy and assessment of myocardial viability to determine candidacy for revascularization; a PET metabolic imaging study of the heart is performed during the inpatient stay to distinguish viable myocardium from scar. Typical codes: C23YYZZ
A patient hospitalized after cardiac transplant develops unexplained graft dysfunction and concern for rejection or ischemia; inpatient PET imaging of the heart using a radionuclide tracer is obtained to assess perfusion and metabolic activity as part of the diagnostic workup. Typical codes: C23YYZZ
