The International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) is the U.S. health system's adaptation of international ICD-9 standard list of six-character alphanumeric codes to describe diagnoses.
Most ICD-9 codes are three digits to the left of a decimal point and one or two digits to the right of one. For example: 250.0 is diabetes with no complications. 530.81 is gastroesophageal reflux disease (GERD).
The biggest difference between the two code structures is that ICD-9 had 14,4000 codes, while ICD-10 contains over 69,823. ICD-10 codes consists of three to seven characters, while ICD-9 contained three to five digits.
A primary user of ICD codes includes health care personnel, such as physicians and nurses, as well as medical coders, who assign ICD-9-CM codes to verbatim or abstracted diagnosis or procedure information, and thus are originators of the ICD codes.
International Statistical Classification of Diseases and Related Health Problems (ICD) ICD serves a broad range of uses globally and provides critical knowledge on the extent, causes and consequences of human disease and death worldwide via data that is reported and coded with the ICD.
The ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification) is a system used by physicians and other healthcare providers to classify and code all diagnoses, symptoms and procedures recorded in conjunction with hospital care in the United States.
CMS will continue to maintain the ICD-9 code website with the posted files. These are the codes providers (physicians, hospitals, etc.) and suppliers must use when submitting claims to Medicare for payment. These codes form the basis of those used for Section 111 reporting, with some exceptions.
During this extended time, the WHO implemented changes and further developed ICD-10. As a result of this work, ICD-10, published in 1990, included significantly more codes and categories: while ICD-9 had only about 17,000 codes, ICD-10 included more than 155,000 codes tracking a significant number of new diagnoses.
The ICD-9 codes associated with preventive services are found in the V codes, which describe the reasons for health care encounters other than disease or injury. For example, V70. 0 should be used for a routine general medical examination performed at a health care facility, and V70.
In addition to billing, ICD-10 codes will be used to advance the science of healthcare including nursing. Nursing's role in data collection and entry is important in the building of the ICD-10 database.

ICD-9 follows an outdated 1970's medical coding system which fails to capture detailed health care data and is inconsistent with current medical practice. By transitioning to ICD-10, providers will have: Improved operational processes by classifying detail within codes to accurately process payments and reimbursements.
