Completing the Transition to ICD-10

Oct. 12, 2015

In accordance with the U.S. Department of Health and Human Services (HHS) mandate, valid ICD-10 codes are required on claims submitted to Blue Cross and Blue Shield of Montana (BCBSMT) for dates of service or inpatient discharge dates on or after Oct. 1, 2015. ICD-10 codes also are required for benefit preauthorization requests submitted on or after Oct. 1, 2015. Use of other codes, such as Current Procedural Terminology (CPT®), HCPCS and Revenue Codes, is not affected by the transition to ICD-10.

Here are some key points to keep in mind:

  • Use of ICD-10 is federally mandated. All Health Insurance Portability and Accountability Act (HIPAA) covered entities must comply, regardless of each patient’s type of health insurance.
  • Coding directly in ICD-10 is encouraged. Coding in ICD-9 and mapping to ICD-10 may be seen as an interim solution, but is not recommended as a best practice.
  • ICD-10 is date of service/discharge date driven. Resubmission or adjustments of previously filed claims must be submitted with the code set used on the original claim.
  • Only one code set per claim is allowed (all ICD-9 or all ICD-10). Claims that contain both ICD-9 and ICD-10 codes will not be accepted.
  • Non-compliant claims may be rejected by your clearinghouse before reaching BCBSMT. You will need to watch electronic reports and work with your clearinghouse to correct and submit affected claims.
