ICD-10 DEADLINE OCT 1, 2014
ICD-10 CM/PCS (International Classification of Diseases, 10th Edition, Clinical
Modification/Procedure Coding System) consists of two parts:
ICD-10-CM (diagnosis coding) was developed by the Centers for Disease Control
and Prevention for use in all U.S. health care settings. Diagnosis coding under
ICD-10-CM uses 3 to 7 digits instead of the 3 to 5 digits used with ICD-9-CM,
but the format of the code sets is similar.
ICD-10-PCS (inpatient procedure coding) was developed by the Centers for Medicare
& Medicaid Services (CMS) for use in U.S. inpatient hospital settings only.
ICD-10-PCS uses 7 alphanumeric digits instead of the 3 or 4 numeric digits used
under ICD-9-CM procedure coding. Coding under ICD-10-PCS is much more specific
and substantially different from ICD-9-CM procedure coding.
The transition to ICD-10-CM/PCS does not affect Current Procedural Terminology
(CPT) codes, which will continue to be used for outpatient services.
