ICD-10 Transition

 Countdown to ICD-10

ICD-10 is HERE!

 About ICD-10


ICD-10 references the International Classification of Diseases, Tenth Revision, Clinical Modification (CM) and Procedure Coding System (PCS) codes. On October 1, 2015, the ICD-9 code sets used to report medical diagnoses and inpatient procedures will be replaced by ICD-10 code sets. Specifically:

Medicare Fee-For-Service (FFS) Claims Processing Guidance for Implementing ICD-10
  • ICD-10-CM codes, for diagnosis coding in all U.S. health care settings, replace ICD-9-CM Volumes I and II.
  • ICD-10-PCS codes, for inpatient procedure coding, replace ICD-9-CM Volume III.

    As of October 1, 2015, ICD-10 codes will be required for all HIPAA transactions as follows:
  • ICD-10-CM codes must be used for all ambulatory and physician claims with dates of service on or after October 1, 2015, and for all inpatient claims with dates of discharge on or after October 1, 2015.
  • ICD-10-PCS codes must be used for all inpatient claims with dates of discharge on or after October 1, 2015.

    Claims billed with ICD-9 codes for services provided outside of the compliance deadline above will be denied.

 West Virginia Medicaid Transition to ICD-10

West Virginia Medicaid is working to transition to ICD-10 and is on track to meet the CMS compliance date of October 1, 2015. Preparations include the following:
  • The MMIS has been updated to the HIPAA X12 transaction standard Version 5010, which allows the system to accommodate the use of ICD-10 codes.
  • Impact assessments are being conducted to identify all potential technical and business impacts of the ICD-10 transition.
  • The MMIS and other technical systems are being updated to process ICD-10 codes according to the CMS compliance guidelines.
  • The Bureau for Medical Services (BMS) is translating ICD-9 to ICD-10 codes based on the current policy. Changes to current policy are not anticipated at this time.
  • Processes and documentation are being updated to reflect the change from ICD-9 to ICD-10 codes.
  • BMS and Molina staff, including the Provider Relations Group, are being trained on ICD-10
