The U.S. Department of Health and Human Services has confirmed in a final rule that October 1, 2015, will be the deadline for the implementation of the International Classification of Diseases, 10th Revision (ICD-10). The final rule requires the use of ICD-9 through September 30, 2015.

We will continue to communicate information to our provider network as it becomes available. Go to www.cms.gov/icd10 for information about ICD-10.

What Will Change

  • Diagnosis codes (ICD-10-CM) and procedure codes (ICD-10-PCS) will have more digits than ICD-9 codes; CPT® and HCPCS codes will not be affected.
  • The number of codes will increase significantly from roughly 14,000 codes to 170,000 codes.
  • The new ICD-10 codes:
    • use updated and more precise medical terminology;
    • enable laterality;
    • allow for the ability to add new codes;
    • include greater specificity (including a greater number of digits);
    • provide more detailed clinical information about conditions, diseases, and injuries.

The implementation of ICD-10 will result in more accurate coding, which will improve the ability to measure health care services, enhance the ability to monitor public health, improve data reporting, and reduce the need for supporting documentation when submitting claims.
