What two resources must coders utilize to avoid errors when assigning diagnosis codes in ICD-10-CM?

The correct choice is grounded in the essential coding processes that ensure accuracy in assigning diagnosis codes in ICD-10-CM. Coders must utilize both the Index and the Tabular List to locate and confirm the appropriate codes.

The Index serves as a quick reference tool that helps coders find codes by looking up terms, such as symptoms or conditions. It acts as a guide to navigate through the extensive coding system, allowing coders to pinpoint potential relevant codes efficiently.

The Tabular List complements the Index by providing a detailed and organized categorization of codes, including their descriptions and additional information, such as inclusion and exclusion notes. This list allows coders to verify the accuracy of the code, check for any specific coding guidelines, and understand the context in which a code should be applied.

Using both resources together minimizes the risk of errors by ensuring that coders understand the terms they are coding and the accurate circumstances that apply to those codes, ultimately leading to better coding practices and compliance with coding standards.
