Use the index to find a code, then confirm it in the Tabular List before assigning it. A code ending in a dash is incomplete, and a code in [brackets] is a manifestation code reported after the underlying condition. Search the whole index.
Frequently asked questions
What is the ICD-10-CM code for Influenza?
The ICD-10-CM Alphabetic Index directs "Influenza" to J11.1. Subterms below it may lead to a more specific code. Always confirm the code in the Tabular List before assigning it.
