International Classification of Diseases, 10th Edition, Clinical Modication (ICD-10-CM) Code Set

The Next Generation of Coding

The International Classification of Diseases, 10th Edition, Clinical Modification/Procedure Coding System (ICD-10-CM/PCS) would enhance accurate payment for services rendered and facilitate evaluation of medical processes and outcomes. A number of other countries have already moved to ICD-10, including:

• United Kingdom (1995)
• France (1997)
• Australia (1998)
• Germany (2000)
• Canada (2001)

The new classification system provides significant improvements through greater detailed information and the ability to expand in order to capture additional advancements in clinical medicine. ICD-10-CM/PCS consists of two parts:

• ICD-10-CM – The diagnosis classification system developed by the Centers for Disease Control and Prevention for use in all U.S. health care treatment settings. Diagnosis coding under this system uses a different number of digits and some other changes, but the format is very much the same as ICD-9-CM
• ICD-10-PCS – The procedure classification system developed by the Centers for Medicare & Medicaid Services (CMS) for use in the U.S. for inpatient hospital settings ONLY. The new procedure coding system uses 7 alpha or numeric digits while the ICD-9-CM coding system uses 3 or 4 numeric digits.The current system, International Classification of Diseases, 9th Edition, Clinical Modification (ICD-9-CM), does not provide the necessary detail on either patients' medical conditions or on procedures performed on hospitalized patients. ICD-9-CM is 30 years old, has outdated and obsolete terminology, uses outdated codes that produce inaccurate and limited data, and is inconsistent with current medical practice. It cannot accurately describe the diagnoses and inpatient procedures of care delivered in the 21st century.
