Michigan Medicaid adult dental changes on January 1, 2027. From that date, dental services for adults in a Medicaid Health Plan will be provided through the Healthy Kids Dental contract, which Delta Dental of Michigan services. The Michigan Department of Health and Human Services told dental providers in a letter dated September 30, 2026 and posted October 1. The covered services do not change. Who pays the claim does, and so does which dentists a patient can see. A practice that is not in Delta Dental's network by January will have its adult Medicaid Health Plan patients reassigned to one that is.
In short
- The change takes effect January 1, 2027, under Section 1627 of Public Act 21 of 2026 (MDHHS, 2026).
- The state budget counts the carve-out as $45.8 million Gross, $11.3 million general fund, in savings (Senate Fiscal Agency, 2026).
- The new plan must honor prior authorizations for 90 days; patients can request continuity of care for up to 6 months (MDHHS, 2026).
- Delta Dental's adult network contract sets urgent care within 48 hours and routine care within 21 business days (Delta Dental of Michigan, 2026).
What MDHHS announced for Michigan Medicaid adult dental in 2027
The letter, Numbered Letter L 26-63, is short. Its key sentences: "Effective January 1, 2027, dental services for adults in a Medicaid Health Plan (MHP) will be provided through the Healthy Kids Dental (HKD) contract. The HKD contract is serviced by Delta Dental of Michigan." And: "This change does not impact dental services currently covered."
It is a budget decision. The Senate Fiscal Agency's summary of the 2026-27 health budget lists new section 1627 as "Dental Carveout" and books "the carving out of the Medicaid adult dental program ($45.8 million Gross and $11.3 million GF/GP)" under Medicaid efficiencies. In plain terms, adult dental comes out of the health plans' contracts and goes to the dental contract the state already uses for children.
MDHHS says a "forthcoming Medicaid policy" will give providers more detail. Health plans, or the dental benefits managers they subcontract, will also contact providers about existing contracts. Patients will hear from MDHHS, from their health plan and from Delta Dental before January.
Why the network question comes first
The letter's operational sentence is this one: "Providers who do not enroll in the Delta Dental of Michigan provider network will have their impacted patients reassigned to a participating network provider beginning January 1, 2027."
Today, according to Delta Dental's April 2026 Medicaid Dental Handbook, health plan adults are seen through its Michigan TriState Advantage network, and "services will not be covered unless your dentist participates" in it. Delta Dental has also published a contract amendment, dated August 25, 2026, for a "Healthy Adults Dental ('HAD') network" covering "adult Michigan Medicaid enrollees and MI Coordinated Health Plan enrollees." Which network name a given contract carries in January is for Delta Dental to confirm. The point for the front desk is simpler: find out, in writing, whether your dentists will be in network for these patients on January 1.
What a dental practice should do before January 1
- Count your affected patients. Pull every adult on a Michigan Medicaid Health Plan. Healthy Michigan Plan adults are covered from age 19 and other Medicaid adults from 21, per Delta Dental's handbook. That list is the revenue at stake.
- Confirm your network status with Delta Dental. The letter points to deltadentalmi.com/join-our-networks. Check each dentist, not just the practice.
- Check CHAMPS enrollment. Delta Dental's adult network amendment says a dentist "will not be permitted to participate in the HAD Network unless he or she is enrolled in CHAMPS," the state's Medicaid system.
- Read the access standards before you sign. The amendment commits the dentist to "urgent care within 48 hours, routine care within 21 business days, preventive service within 6 weeks and initial appointments within 8 weeks" from a request. Look at your schedule honestly.
- List in-progress treatment. Crowns, dentures and root canals that will straddle January need their prior authorizations tracked against the 90-day window, and the continuity of care request route noted for anything longer.
- Tell your patients before the state does. A short call or text explaining that their dentist is staying in network, or what happens if not, prevents a patient from assuming they have to leave.
The mistake most practices make at step 5
They assume a prior authorization approved by the old plan is good until the work is done. MDHHS's protection is narrower: "Prior authorizations must be honored by the new plan for 90 days following enrollment into the new plan." A denture case that started in November and finishes in April can run past it. For treatment where stopping would harm the patient, the letter allows a request for "continuity of care" for up to six months. That request is the patient's, so the practice has to tell them it exists.
What does not change for patients
Covered services stay the same. Delta Dental's current handbook lists exams and cleanings every six months, fillings, root canals, crowns, extractions, and complete and partial dentures every five years, and says "there are no copayments for covered services." Implants, bridges and cosmetic work are excluded. Under the adult network amendment, a non-covered service can be billed only if the dentist tells the patient the cost and gets "a signed private pay form on the date of service," and "Enrollees cannot be charged for a missed appointment."
Where we fit
Practices that already lived through the children's version of this, covered in our post on Healthy Kids Dental 2026, know the pattern: the letters go to patients, and the questions come to the front desk. Our healthcare work runs recall that stops when the patient replies, reminders that fill cancelled slots, and an assistant that answers "is my dentist still covered?" at any hour. For the other Medicaid change adult patients are asking about, read Healthy Michigan Plan work requirements.
Check the network now. January is when patients find out.
