Note: The references and links below may not have been edited to include the proposed implementation date change.

On Jan. 16, 2009, the U.S. Department of Health and Human Services (HHS) released a final rule mandating that everyone covered by the Health Insurance Portability and Accountability Act (HIPAA) must transition from ICD-9 code sets and adopt ICD-10-CM diagnosis codes and ICD-10-PCS procedure codes.

ICD-9 codes will be replaced with ICD-10-CM diagnosis codes (used on all claims) and ICD-10-PCS procedure codes (used for inpatient facility claims only). This change does not affect Current Procedural Terminology (CPT®) coding for outpatient procedures. HHS issued a final rule mandating compliance with the new, ICD-10 code set by Oct. 1, 2014. For details, view the news release  on the HHS website.
