Does Medicaid Cover Dentures in Washington State?

Yes. In Washington state, Medicaid — known locally as Apple Health — covers complete dentures and resin partial dentures for enrolled adults 21 and older when a dentist documents them as medically necessary.¹ Coverage includes the extractions and surgical preparation needed to get you ready, plus later relines, rebases, and repairs to keep the dentures working. The limits around replacements, materials, and prior authorization are tighter than most people expect, and knowing them up front changes how you plan the whole process.

What Apple Health Pays For

The covered denture services for adults are:

One initial upper and one initial lower complete denture per person.²
Resin partial dentures when you still have natural teeth, with prior authorization required.³
Extractions and alveoloplasty (reshaping the jawbone) before dentures are placed.¹
One laboratory reline or rebase every three years, allowed starting six months after the denture was placed.²
One repair per arch every twelve months, as long as the repair would cost less than a replacement.²
Adjustments, covered starting three months after delivery.

The Washington State Health Care Authority (HCA) administers these benefits, and you use your ProviderOne services card at participating dental offices.

What Apple Health Will Not Cover

Several denture types people commonly ask about fall outside the program entirely. Under WAC 182-535-1100, Apple Health does not pay for:⁴

Immediate dentures (placed the same day teeth are extracted)
Cast-metal framework partial dentures
Flexible base partial dentures, sometimes sold under names like Valplast
Interim or temporary dentures
Permanent soft relines (standard hard relines are covered)
Precision and semi-precision attachments and their replacement parts
Unilateral partial dentures (designed for only one side of the mouth)
Replacement of second or third molars on any removable prosthesis

The immediate denture exclusion catches people most often. If teeth are being pulled in preparation for dentures, expect a healing period before conventional dentures are fabricated and placed.

Replacement Limits You Need to Know

The replacement rules are strict, and the lifetime cap on complete dentures is the single most important thing to plan around.

Complete dentures. One replacement per arch, per lifetime. The replacement cannot happen until at least five years after the original was placed, must be medically necessary, and requires prior authorization.²
Partial dentures. A new resin partial can replace an existing one after at least three years, if medically necessary.²
Switching from a partial to a complete denture. Covered after at least three years from when the partial was placed, if you’ve lost enough teeth to need a full denture.²

Once you’ve used your initial complete denture and the one lifetime replacement, Apple Health will not pay for another. That is why the covered relines, rebases, and repairs matter so much: use them to extend the life of the dentures you have before reaching for a replacement.

Who Qualifies

You need to be enrolled in Apple Health first. Most non-disabled, non-elderly adults qualify under the New Adult category when modified adjusted gross income is at or below 138% of the federal poverty level — $1,835 a month for one person, $3,795 a month for a household of four.⁵

Enrollment alone does not guarantee dentures. Your dentist must determine and document medical necessity, meaning the missing teeth significantly affect your ability to chew, speak, or maintain your health. For services that require prior authorization, HCA reviews that documentation before coverage is approved.

Prior Authorization

Your initial complete dentures — the first upper and lower set — do not need prior authorization.³ Almost everything else does, including:

All resin partial dentures
Replacement complete dentures
Upgrading from a partial to a complete within three years of the partial’s placement
Any additional reline or rebase beyond the one-per-three-years limit

Your dentist handles the paperwork, but you should know what HCA requires in the packet:³

Diagnostic X-rays of all remaining teeth
A completed Tooth Chart form (HCA 13-863)
A treatment plan covering restorative and periodontal needs
Chart notes showing a cleaning or periodontal treatment within the past twelve months and that other restorative work has been completed
Photos of the current appliance when the request is for a wear-or-breakage replacement, labeled with your name, date of birth, the date taken, and the provider’s name
Documentation of medical necessity

The cleaning requirement is the one that stalls requests. HCA wants evidence that your remaining teeth are stable before approving a partial or a replacement. If you haven’t had a cleaning in the last year, schedule that first.

If Your Request Is Denied

You can appeal, and the route depends on how you receive your benefits.

If you’re enrolled through a managed care organization such as Molina Healthcare, Coordinated Care, or UnitedHealthcare, you have to use that plan’s internal grievance and appeal process before you can ask the state for a hearing.⁶ The denial letter from the plan explains how to start.

If you’re on fee-for-service Apple Health, or you’ve already exhausted the managed care appeal, you can request an administrative hearing. You generally have 90 days from the denial date to file.⁷ Requests go through the Office of Administrative Hearings online or at 800-583-8271. An administrative law judge hears the case by phone or in person, and if that decision goes against you, HCA’s Board of Appeals can review it.⁶

Finding a Dentist Who Takes Apple Health

Not every dentist accepts Apple Health, and among those who do, not all take new patients for denture work. HCA’s Find a Provider tool lets you search participating dentists by location.⁸ DentistLink, a free referral service run by the Arcora Foundation for Washington residents, connects you with a participating dentist by phone or text at 844-888-5465. Call the office directly before scheduling to confirm they’re currently accepting new Apple Health patients for denture services; online directories lag behind actual availability.
