More About ICD-9-CM
Overview
The International Classification of Diseases, Ninth Revision,
Clinical Modification (ICD-9-CM) is based on the World Health
Organization's Ninth Revision, International Classification
of Diseases (ICD-9). The ICD-9-CM is the official system of
assigning codes to diagnoses and procedures associated with
hospital utilization in the United States. The ICD-9 is used to
code and classify mortality data from death certificates.
The ICD-9-CM consists of:
-
a tabular list containing a numerical list of
the disease code numbers in tabular form (Volume 1);
-
an alphabetical index to disease entries
(Volume 2), and
-
a classification system for surgical,
diagnostic, and therapeutic procedures (alphabetic index
and tabular list).
The
National Center for Health Statistics (NCHS)
and the
Centers for Medicare and Medicaid Services (CMS)
are the U.S. governmental agencies responsible for overseeing all
changes and modifications to the ICD-9-CM.
Scope
The intent of ICD-9-CM is to standardize disease and procedure
classification throughout the United State, and to gather data
about basic health statistics.
Purpose
HIPAA legislation requires the ICD-9-CM to be used for health
services billing and record keeping.
Relation to Professional Scope of Practice
The speech-language pathologist and audiologist practicing in
a medical setting, especially in a hospital, may have to code
delivery of services according to the ICD-9-CM.
