ICD-10-PCS Code For Coronary Arteries: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B221 includes procedures performed to image coronary artery structures in the heart using computerized tomography. These ICD-10-PCS codes are used for inpatient documentation when multiplanar reformatted digital images of multiple coronary arteries are captured to evaluate coronary anatomy or pathology. Accurate coding within the ICD-10-PCS B221 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Coronary Arteries Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging of the coronary arteries, multiple, using reformatted multiplanar digital displays derived from multiple external ionizing radiation exposures. These procedures target the heart and its coronary arterial system to visualize patency, stenosis, and anatomic detail. Accurate ICD-10-PCS coding reflects the specific imaging operation and body part examined and is important for correct inpatient reimbursement and clinical documentation.

Code Attributes

Character	ICD-10-PCS Category	Code Group Details
B	Section	Imaging
2	Body System	Heart
2	Operation	Computerized Tomography (CT Scan)
1	Body Part	Coronary Arteries, Multiple

When to Use

Use a code from this group when a patient undergoes a computerized tomography study producing reformatted multiplanar images of multiple coronary arteries during an inpatient encounter. These codes apply when the imaging is performed to assess coronary artery anatomy, suspected stenosis, or other coronary pathology requiring CT-based evaluation.

Typical Clinical Scenarios

A 68-year-old male is admitted to the hospital with acute chest pain, elevated cardiac enzymes, and non-diagnostic ECG changes suggesting possible acute coronary syndrome; inpatient clinicians need rapid anatomic assessment of multiple coronary arteries to evaluate for obstructive coronary disease and plan urgent management, so a CT-based multiplanar coronary angiographic study with contrast is performed. Typical codes: B22110Z, B2211ZZ
A 55-year-old female with a history of atypical chest pain and a prior equivocal stress test is admitted electively for inpatient workup to obtain high-resolution imaging of her coronary anatomy to characterize suspected multi-vessel atherosclerotic disease; a scheduled contrast-enhanced CT with computer-reformatted multiplanar displays of multiple coronary arteries is obtained to guide further treatment planning. Typical codes: B22100Z, B2210ZZ
A 72-year-old patient with prior coronary stents presents with worsening effort angina after recent intervention, raising concern for in-stent restenosis versus progression in other vessels; inpatient imaging using CT with multiplanar reconstruction of multiple coronary arteries, potentially including specialized intravascular optical coherence assessment recorded on imaging datasets, is performed to evaluate stent patency and adjacent vessel disease. Typical codes: B221Z2Z, B221YZZ
