Term: Cardiac Catheterization (Diagnostic Angiogram)

Glossary Definition

Last Updated: 2020-05-21


The most accurate method for evaluating and defining ischemic heart disease (IHD), also known as coronary artery disease (CAD), cardiac catheterization is used to identify the location and severity of CAD. The images that are produced by the prodecure are called the angiogram, which shows the extent and severity of blockages in coronary arteries.

In Fransoo et al. (2009), cardiac catheterization is defined by ICD-9-CM procedure codes 37.21 to 37.23, or 88.52 to 88.57, or by CCI codes 2.HZ.28 or 3.IP.10 in any procedure field of a hospital discharge abstract (inpatient or outpatient).
