ICD-9-CM Codes, tabular index

The ICD-9-CM is divided into three volumes. Volumes I and II are the alphabetic index and the tabular index used for diagnosis coding. Volume III has its own alphabetic and tabular index which are used for inpatient coding.

We have listed the codes for volumes I and II below.

ICD-9 Coding Application

In the ICD-9-CM, volumes I and II, codes are structured as 3-5 digit codes, and with the exception of V and E codes, are all numeric in nature.

Clicking through to a specific code you'll see what it's used for, and in some instances what it doesn't apply to.


480.8 Pneumonia due to other virus not elsewhere classified
  • congenital rubella pneumonitis (771.0)
  • influenza with pneumonia, any form (487.0)
  • pneumonia complicating viral diseases classified elsewhere (484.1-484.8)
714 Rheumatoid arthritis and other inflammatory polyarthropathies

Gross Anatomy

The ICD-10 codes are much more detailed than the ICD-9-CM codes were.

Medical coders will need to know their Medical Terminology, Gross Anatomy, Pathology, and Common Anatomy Terms.

ICD-10 Draft

For those who can self-teach, consider purchasing an ICD-10 draft edition.

Reading through the ICD-10 coding guidelines, reading through the tabular index, and practicing looking up codes is a great way to get some hands on experience.

Also consider creating a list of common ICD-9-CM codes that you use on a daily basis and then create your own cross-walk to the ICD-10 codes that will replace them.

Use this opportunity to look up words and anatomy you may not recognize as well.
