CMS Reinstates Ban on Adult Dental Services as an Essential Health Benefit

Edited by Dentaltown staff

Federal regulators have reinstated a prohibition on treating routine adult dental services as an essential health benefit in Affordable Care Act Marketplace plans, reversing a 2024 policy that would have let states add the coverage starting in 2027.

The Centers for Medicare and Medicaid Services finalized the change in its 2027 Notice of Benefit and Payment Parameters, the annual rule that sets standards for qualified health plans and issuers on the ACA exchanges. The rule takes effect July 20.

CMS said the reversal better aligns with the ACA, which directs that the scope of essential health benefits match a typical employer plan. The statute explicitly includes pediatric oral health services but not routine adult dental care. The agency said adult dental services are not generally covered in employer-sponsored major medical plans and warned that embedding them as an essential benefit could create “illusory” coverage and reduce demand for stand-alone dental plans that currently serve millions of enrollees.

The decision undoes a provision finalized in the 2025 Payment Notice that had allowed states to include adult dental benefits in their essential health benefit benchmark plans beginning in 2027.

The Organized Dentistry Coalition, which includes the American Dental Association, opposed the change in a March comment letter. The coalition argued that the rationale does not reflect current coverage, noting that qualified health plans in 36 states already embed adult dental benefits and that Medicare Advantage plans show insurers have the infrastructure to administer dental coverage. It said continuing to bar adult dental as an essential benefit no longer serves its original purpose and could undermine access to care.

The final rule was not uniformly unfavorable to organized dentistry. CMS declined to finalize a proposal to lower the essential community provider participation threshold from 35% to 20%, a change provider groups had warned could weaken access to safety-net providers such as federally qualified health centers. The agency also left medical loss ratio reporting requirements unchanged after the coalition argued that such transparency helps ensure plans invest in patient care.
