Subterms in the ICD-10-CM Index are arranged in what manner for coding qualifiers?

Subterms in the ICD-10-CM Index are organized in alphabetical order to facilitate easier and more efficient coding. This arrangement allows coders to quickly locate specific conditions and their associated qualifiers by following an A to Z sequence. The index is structured such that terms that begin with the same letter are grouped together, making it intuitive for coders to find the appropriate codes.

In the context of medical coding, this system of organization helps streamline the coding process, ensuring that coders can accurately assign codes without unnecessary delays. The alphabetical arrangement ensures that the subterms are easily accessible and allows coders to look up terms based on their familiarity with medical language or nomenclature.
