Does OHP Cover Dentures? Eligibility, Process, and Denials

Yes, the Oregon Health Plan does cover dentures. OHP pays for full dentures once every ten years and partial dentures once every five years, for members of any age, as long as a dentist documents that the dentures are medically necessary and dentally appropriate.¹ There are no copays or deductibles for the benefit.² The catch is prior authorization, eligibility rules that turn on how many teeth are missing, and, in much of the state, finding a dentist who will take the case.

What OHP Pays For

OHP’s prosthodontic benefit covers three categories of removable dentures. Each requires prior authorization through the member’s dental plan.

Complete upper or lower dentures, including immediate full dentures placed right after extractions, once every ten years.³
Resin-base or cast-metal partial dentures, including immediate partials, once every five years.³
Interim partial dentures (flippers), once every five years, but only when the member is missing one or more front teeth.³

Replacing an existing partial with a full denture is payable five years after the partial was originally placed. The replacement clocks follow the member, not the plan, so switching Coordinated Care Organizations does not reset them.⁴

Who Qualifies for a Partial Denture

The tooth-count thresholds differ by age. Members under 21 qualify when at least one front tooth or four or more back teeth are missing in a single arch. Adults 21 and older need one or more missing front teeth or six or more missing back teeth per arch, and the missing teeth must be causing difficulty chewing.³

What OHP Will Not Cover

Implants and implant-supported dentures are not covered. The administrative rules only pay for implant-related work when a failed implant body has to be removed because of severe peri-implantitis, fracture, or abscess. Placing implants, or fabricating dentures that attach to them, is not a benefit.³ Dentures made purely for cosmetic reasons are also excluded.⁴

How To Get Dentures Through OHP

Most OHP members are enrolled in a Coordinated Care Organization, which contracts with one or more dental networks. Which networks are available depends on the county you live in.⁵ The path to a finished denture generally runs like this:

Call your CCO or dental plan to find a dentist who provides dentures. Fee-for-service members can search the state’s provider directory or call OHP Care Coordination at 800-562-4620.¹
Get an evaluation. Before prosthodontic treatment can move forward, the rules require that active decay be controlled and oral hygiene be adequate.⁶
The dentist submits a prior authorization request to your dental plan. Some networks, such as CareOregon Dental, use a referral process instead of a formal prior authorization, but the effect is the same.⁷⁸
Once approved, the dentist takes impressions and fabricates the dentures. The finished dentures must be delivered within 45 days of the final impression, and you must have active OHP coverage on the date of that impression.³

Adjustments, Repairs, and Early Replacement

Between replacements, OHP covers routine upkeep. Adjustments are covered up to four per year per arch, starting six months after delivery; anything sooner is built into the original denture fee.³⁹

Getting a new denture before the ten- or five-year mark is possible, but narrow. The existing denture has to be beyond repair, and the need has to come from acute trauma, a natural disaster, or a catastrophic illness that caused additional tooth loss, such as cancer treatment or medication side effects leading to severe periodontal disease. Dentures lost or damaged through neglect or intentional misuse generally will not be replaced early.⁴

If Your Denture Request Is Denied

A dental plan that denies a denture request has to send a written Notice of Action explaining why. If you are in a CCO, you appeal to the CCO first, and it has 16 days to send a written resolution.¹⁰ If the CCO upholds the denial, you have 120 days from that resolution to request a contested case hearing through the Oregon Health Authority.¹¹ You can also ask that existing benefits continue during the appeal, though the plan can recover the cost of interim services if the denial is upheld. Free legal help is available through the Oregon Law Center and Legal Aid Services at the Public Benefits Hotline, 1-800-520-5292.

Finding a Provider Can Be the Hardest Part

The benefit reads cleanly on paper. In practice, less than half of Oregon’s dentists accept Medicaid patients, and 32 of the state’s 36 counties do not have enough Medicaid dental providers to meet demand.¹² Dentures are among the more labor-intensive services a dentist provides, and providers surveyed by the state have specifically flagged the ten-year replacement limit as a source of frustration with the program.¹³ If the first office you contact cannot take you, ask your dental plan directly for a list of network dentists currently accepting new prosthodontic cases, and be prepared to travel if you live outside the Portland or Willamette Valley metro areas.
