Ohio Medicaid Managed Care Entity External Medical Review

Providers who disagree with the Ohio Medicaid Managed Care Entity’s determination on appeal to deny, limit, reduce, suspend, or terminate a covered service for lack of medical necessity may request an External Medical Review with Permedion. The request for External Medical Review must be submitted to Permedion within 30 calendar days of the written notification that the internal appeals process has been exhausted. Providers may also request an External Medical Review if the MCE has not met the required Provider Internal Appeal or Provider Claim Dispute resolution time frame for a denial based on medical necessity.

Providers must complete the "Ohio Medicaid MCE External Review Request"" form and submit to Permedion together with the required supporting documentation. Upload this request form and supporting documentation to Permedion’s provider portal at https://ecenter.hmsy.com/ (new users will send their documentation through secured email at IMR@gainwelltechnologies.com to establish portal access). Providers should attach to this request form only additional documents not originally provided to the MCE during their review process.

For more information about the External Medical Review process, please contact Permedion at 1-800-473-0802, Option 2.
