Use of Both Alphabetic Index and Tabular List

Why This Topic Matters

Using only one part of the classification system can lead to less specific or incorrect code selection. This article matters because it highlights the importance of cross-checking entries and notes to improve coding accuracy in both diagnosis and procedure coding.

Article Sections

1. General guidance on using the Alphabetic Index and Tabular List

   Introduces the need to consult both parts of the classification system when assigning codes. It emphasizes verification, instructional notes, and specificity in code selection.

2. Diagnosis coding examples

   Presents multiple diagnosis coding scenarios that illustrate how index entries are confirmed or refined through tabular review. The examples cover respiratory, musculoskeletal, ophthalmic, and hernia-related topics.

3. Procedure coding example

   Shows how the same general approach applies to procedure coding using the Procedure Alphabetic Index and the Tabular List. The section discusses verification for intestinal resection and related procedural classification considerations.
