On January 15, 2009, the Secretary of the Department of Health and Human Services released a final rule calling for the adoption of a new edition of the International Classification of Diseases (ICD) standards known as the 10th edition using Clinical Modifications (CM) and the Procedure Coding System (PCS). The final rule adopts ICD‐10‐CM for reporting patient diagnoses and ICD‐10‐PCS for reporting hospital inpatient procedures ‐ both will replace ICD‐9‐CM.
The federal government issues rules and regulations regarding coding. Some relevant links are listed here. If you are an ACC student, staff, or faculty member and know of other government sites or documents that would be useful, let me know.
