What is the role of the AHA Tabular List in coding guidance?

• A. To provide CPT codes
• B. To guide diagnosis code selection and structure
• C. To list hospital supplies
• D. To determine patients' eligibility for services

Answer: (B)

Guiding diagnosis code selection and the code structure. The AHA Tabular List is the part of ICD-10-CM you use after finding a condition in the Alphabetic Index; it shows the exact code to use and how that code fits within the overall coding scheme. It organizes codes into chapters and categories and includes notes that tell you when to code additional conditions, when to use a combination or secondary codes, and any code restrictions. By confirming the exact code and following the notes, you ensure accurate coding and proper sequencing of diagnoses. This resource does not provide CPT codes, does not list hospital supplies, and does not determine patient eligibility for services.
