Michigan is changing how adult dental benefits are administered for Medicaid managed-care members. Effective January 1, 2027, adult dental services for members enrolled in a Medicaid Health Plan will move under the Healthy Kids Dental (HKD) contract, which is serviced by Delta Dental of Michigan.
For dental practices and DSOs treating Michigan Medicaid patients, this is not just a contracting announcement. It creates immediate questions around network participation, prior authorizations, treatment already in progress, patient reassignment, and front-office eligibility workflows.
What is changing
The Michigan Department of Health and Human Services (MDHHS) announced on October 1, 2026 that, beginning January 1, 2027, adult dental services for Medicaid Health Plan members will be provided through the Healthy Kids Dental contract serviced by Delta Dental of Michigan.
MDHHS says the change does not alter dental services currently covered. The administrative pathway is changing, and additional Medicaid policy guidance is expected.
Providers should also expect communications from their Medicaid Health Plan or its dental benefits manager explaining how the transition affects existing provider contracts.
The most important operational issue: network participation
Practices that already participate with Delta Dental of Michigan should still verify how their locations, clinicians, Medicaid enrollment records, and effective dates map into the new arrangement.
Practices that do not accept HKD through Delta Dental of Michigan have a more consequential decision.
MDHHS states that providers may choose to join the Delta Dental of Michigan network. If a provider does not enroll, affected patients will be reassigned to a participating network provider beginning January 1, 2027.
That makes network status a revenue-cycle issue, not simply a credentialing task.
What dental organizations should verify now
- Identify every Michigan location currently treating adult Medicaid Health Plan members.
- Confirm whether each rendering provider and location participates in the relevant Delta Dental of Michigan network.
- Do not assume an existing commercial Delta Dental relationship automatically establishes participation for this Medicaid arrangement; verify the applicable network and effective date.
- Inventory active treatment plans and open prior authorizations for affected patients.
- Build a list of patients whose treatment could extend beyond December 31, 2026.
- Prepare front-desk and billing teams for eligibility and payer-routing changes on January 1.
Existing prior authorizations have a 90-day protection
One of the most important details in the MDHHS notice is the transition protection for existing authorizations.
MDHHS requires the plans involved in the transition to honor prior authorizations for 90 days following enrollment into the new plan.
Operationally, teams should not treat that protection as a reason to ignore the transition. Create an authorization inventory before January 1 that includes the patient, procedure, authorization number, approval dates, remaining treatment, supporting documentation, and expected date of service.
If a service occurs during the transition window, retain evidence of the original authorization and verify how the receiving plan wants it referenced on the claim or in its portal.
Continuity of care may extend to six months
MDHHS also states that beneficiaries may request continuity of care for up to six months for ongoing treatment when discontinuing treatment would cause serious detriment to the beneficiary's health.
That distinction matters.
The 90-day prior-authorization protection and the potential six-month continuity-of-care period are related transition protections, but they are not the same thing. Do not operationalize them as a blanket six-month authorization extension.
For complex or staged treatment already underway, practices should identify potentially affected patients early and document the clinical circumstances supporting continuity when appropriate.
A practical 90-day readiness plan
Now through November
Map exposure. Quantify adult Michigan Medicaid patients by location, provider, plan, active treatment and open authorization.
Verify network status. Confirm the applicable Delta Dental of Michigan participation status for every relevant provider and location.
Resolve credentialing gaps early. If participation is desired and enrollment is required, begin before the year-end rush. Do not assume an application submission date equals an effective participation date.
December
Reverify active treatment. Produce a transition worklist of patients with treatment expected to cross January 1.
Capture authorization evidence. Store authorization numbers, approval notices, relevant clinical records and dates in a place the billing team can retrieve quickly.
Update workflows. Train eligibility, scheduling and billing teams on the January 1 routing change and establish an escalation path for unclear eligibility or network responses.
January 1 and after
Verify eligibility at the point of service. Do not rely solely on payer information captured before the transition.
Watch first claims closely. Track rejection and denial patterns separately for the transitioned population so configuration problems can be distinguished from true coverage issues.
Escalate continuity cases. For ongoing treatment where interruption could create serious detriment, follow the plan's continuity-of-care process and preserve the supporting record.
What Axlow users should watch
This transition is a good example of why payer policy intelligence needs to be tied to effective dates and operational consequences.
The next important documents are the forthcoming Michigan Medicaid policy guidance and plan/provider communications that clarify implementation details. Those materials may add instructions for claims submission, credentialing, authorization handling, or provider contracting.
Axlow will continue tracking payer-policy evidence as new source material becomes available.
Source and limitations
Primary source: Michigan Department of Health and Human Services, “October 1 2026 Adult Dental Letter,” published October 1, 2026: https://www.michigan.gov/mdhhs/assistance-programs/medicaid/portalhome/medicaid-providers/medicaid-provider-alerts/all-alerts-and-updates/october-1-2026-adult-dental-letter
The MDHHS letter states that a forthcoming Medicaid policy will provide additional information. Teams should therefore treat the October 1 letter as the current transition framework and verify subsequent guidance before making payer-specific billing or coverage determinations.
Ask Axlow: Use Axlow to research payer policies, compare documented requirements, and trace answers back to source evidence. Axlow provides policy intelligence and is not a payment determination; providers remain responsible for verifying member-specific benefits, network status, and current payer requirements.
