Your move to Medical Mutual on January 1, 2027.

Received a letter about your 2027 health plan?

Beginning the week of September 28, 2026, 90-day discontinuation notice letters are being mailed to participating employer groups and their employees, as required by the Ohio Department of Insurance. The letter is titled “Important Information About Your 2027 Health Plan Transition.” It’s expected, and here’s what it means.

For employers: what to do

The steps Medical Mutual has laid out for moving your group, in order. As your broker, OCIA handles the paperwork with you.

1. 1

   Choose your 2027 plan and accept your rate offer.

   To confirm acceptance and begin implementation, Medical Mutual needs the completed employer application, an updated Medical Mutual membership census, and the signed rate offering — plus a COBRA waiver, if applicable. Signing the employer application also serves as acknowledgement of the participation agreement, plan documents and underwriting regulations.

2. 2

   Allow 5–10 business days for setup.

   That’s how long Medical Mutual needs after complete and accurate materials are received for your group and enrollment to be available in its systems.

3. 3

   Use the Medical Mutual Employer Dashboard (MED).

   MED is the employer’s administrative resource — where you sign up for EFT and access ID cards, claims, benefits and plan resources. Between setup and January 1, make any enrollment updates in MED so employees who need access are enrolled and terminated employees are removed. Enrollment exceptions can only be processed retroactively for up to 60 days.

4. 4

   Audit your enrollment before paying your first invoice.

   Prior to paying the first invoice — and preferably prior to Jan. 1, 2027 — all groups should audit their enrollment in MED to ensure it is complete and correct.

5. 5

   Identify employees in active treatment early.

   Employees or dependents with ongoing treatment, scheduled procedures, pregnancy-related care, behavioral health care, oncology care, complex specialty care or other time-sensitive services may be candidates for a transitional care waiver. Requests should be submitted with or shortly after implementation. Waivers cannot be approved until implementation is complete, and approval is not automatic — it is subject to Medical Mutual review, plan provisions, clinical criteria and applicable regulatory requirements.

6. 6

   Review COBRA and continuation coverage.

   Beginning Jan. 1, 2027, the Ohio Chamber Health Benefit Program will follow the plan documents and federal guidelines for COBRA and state continuation eligibility, based on group size. Medical Mutual will grandfather participants who have already elected COBRA, regardless of group size: if an employer not subject to COBRA (fewer than 20 employees) currently has a COBRA beneficiary, that person may remain on the plan until the continuation period ends. Groups with fewer than 20 employees must self-administer COBRA beginning Jan. 1, 2027, or can stay with their current COBRA vendor (may incur fees).

7. 7

   On an HSA plan? Decide on banking.

   Banking fees are included in premium when the group uses Medical Mutual’s authorized banking solution. Maintaining an outside banking solution may cause the group to incur additional fees.

Find your 2027 plan

Medical Mutual has identified the 2027 plan option that most closely aligns with each current plan. Find your current plan ID below — it’s the “Med Plan Code” on the 2026 plan grid, and your OCIA advisor can look it up for you. Four additional plan options are also available if you’d like to explore other coverage choices during enrollment.

No match for that ID. If your current plan ID is not listed, Medical Mutual may not have received sufficient plan information from your previous carrier to provide a recommended match — all available plan options remain open to you, and we can help identify the closest fit.
