Review the cardiovascular system to make ICD-10-CM coding less confusing

Why This Topic Matters

Cardiovascular coding can be difficult because the diagnosis structure in ICD-10-CM is more specific than older classification systems. A basic grasp of heart anatomy, blood flow, and common cardiovascular terminology can help coders navigate the broader set of ICD-10-CM cardiovascular categories discussed in the article.

Article Sections

1. Reviewing cardiovascular anatomy

   This section covers the basic structure of the heart, valves, pericardium, tissue layers, blood flow, and the major components of the circulatory system. It provides the anatomy background used later in the article's coding discussion.

2. Coding ICD-10-CM cardiovascular conditions

   This section introduces the ICD-10-CM cardiovascular coding discussion, focusing on general reporting changes, coronary artery disease categories, ischemic heart disease groupings, exclusions, and related guidance. It also includes a case-based discussion related to cardiovascular diagnosis reporting.
