Health informatics professionals work at the intersection of healthcare, technology, and information. They develop and manage health information systems to support patient care and administrative tasks. There are two main areas of health informatics - management, which involves designing systems, ensuring privacy and security, and training users, and technical, which focuses on developing and integrating systems. Health informatics professionals analyze patient data, assign medical codes, and ensure information is documented and communicated properly within legal and ethical standards.

ICD-9-CM Coding
The code book:
Contains three volumes
 Volume 1 – Tabular List of Diseases
 Volume 2 – Index to Diseases
 Volume 3 – Index to Procedures and Tabular List of
Procedures
Physicians’ offices and outpatient facilities use only
Volumes 1 and 2 when coding

Main Term in Diagnosis
Main term – condition causing the patient to be
sick.
Example: Urinary Tract Infection
Infection is the main term in this diagnosis.
Urinary Tract is the location of the infection and would
not be the first place to look in the index (Volume 2).

Basic Steps
Locate the main term in the alphabetic
index (Volume 2).
Review the subterms.
Follow cross-references.
Verify the code found in the alphabetic index in
the Tabular List (Volume 1).
Assign the correct code.

Used to code medical procedures and services
performed in outpatient facilities
Has an index and a numerical listing

CPT Coding
To use the code book:
Go to the index, locate the procedure
Go to the numerical listing to determine which code is
appropriate for the procedure listed in the charge form

The CPT index is organized by alphabetical main
terms which include:
procedures
services
organs
anatomic sites
conditions
eponyms
abbreviations

27. Procedure Codes
CPT Coding
This is quite different from what you learned from the
ICD-9-CM coding.
Reminder, with ICD-9-CM coding, you had to pick a
main term. Not true with CPT coding
For this reason, most students like CPT coding over
ICD coding
