The U.S. Department of Health and Human Services confirmed in a final rule that October 1, 2015, was the deadline for the implementation of the International Classification of Diseases, 10th Revision (ICD-10). The final rule required 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 for information about ICD-10.

What has changed

  • Diagnosis codes (ICD-10-CM) and procedure codes (ICD-10-PCS) now have more digits than ICD-9 codes; CPT® and HCPCS codes were not affected.
  • The number of codes increased 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 results in more accurate coding, which improves 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.
