What two components must coders use when locating and assigning diagnosis codes in ICD-10-CM?

• A. Payer policies and guidelines.
• B. Index and tabular list.
• C. Coding guidelines and index.
• D. Tables and index.

Answer: (B)

Using the index and tabular list is crucial for accurately locating and assigning diagnosis codes in ICD-10-CM. The index serves as a guide to help coders search for specific conditions or terms, providing a structured way to find the relevant codes. Once a coder finds a potential code in the index, they must cross-reference it with the tabular list, which offers detailed information about each code, including descriptions, inclusion and exclusion notes, and any applicable additional codes. This combination ensures that coders not only find the correct code but also understand its context and specific requirements. The tabular list provides a comprehensive overview of how codes relate to each other and the nuances of each diagnosis, ensuring that coders adhere to coding standards and guidelines. The other options do not incorporate both essential components needed for code assignment in a manner that aligns with the coding process in ICD-10-CM.
