Attention all Ohio Medicaid providers

February 2023 update: Please be aware that some Humana Healthy Horizons® in Ohio Medicaid member ID cards were sent out with values mismatched under Member ID Number and Plan ID Number fields. Learn what this means for you and what we’re doing for our affected members, PDF.

Exciting changes to Ohio’s Medicaid program as of Feb. 1, 2023

The Next Generation managed care plans, new Electronic Data Interchange (EDI) module, and Fiscal Intermediary (FI) have been implemented. With the launch of the new EDI and FI, there are some activities for providers that have stayed the same and some that have changed.

Claims and prior authorization (PA) submitted through a trading partner

Key changes effective Feb. 1

  • ODM’s new EDI begins accepting trading partner fee‐for‐service (FFS) and managed care claims.
  • Provider claims submitted to trading partners must include the Medicaid member ID (MMIS).
    • Medicaid ID should be obtained with each encounter.
    • Member eligibility can be verified using the ID through the Provider Network Management (PNM) module, which redirects to MITS.
  • For professional claims, only one rendering provider is allowed per claim. Individual claims must be submitted for services rendered by different providers. (See exceptions for Federally Qualified Health Centers and Rural Health Clinics in “Rendering Provider on Claims Submissions.”)

What did not change on Feb. 1

  • FFS prior authorizations will continue to be submitted through the PNM module link to MITS.
  • Managed care prior authorizations will continue to be submitted to each plan using their existing processes.
  • The new EDI will not accept prior authorizations of any kind.

Portal submitted claims and all prior authorizations

Key changes effective Feb. 1

  • All Next Generation plans will have portals for direct data entry and providers should consult their provider handbook for instructions on how to bill using the portal.
  • FFS claims will continue to be submitted through the PNM module link to MITS.
    • MMIS ID will be the identifying number used for FFS claims processing.

What did not change on Feb. 1

  • Continue using managed care plan portals to direct data enter claims and prior authorizations.
  • Plan eligibility will continue to be accessed through MCO portals.
  • Continue using the PNM module, which redirects to MITS, as you do today to submit, adjust, and search FFS claim and prior authorization information. 

The Next Generation managed care plans changes do not apply to MyCare Ohio plans, which will continue to provide benefits to Ohioans who receive Medicaid and Medicare benefits, with enhanced coordination of medical, behavioral, and long-term care services.
