Clients described in WAC 182-535-1060 are eligible to receive the prosthodontics (removable) and related services, subject to the coverage limitations, restrictions, and client-age requirements identified for a specific service.

(1) Prosthodontics. The medicaid agency requires prior authorization for removable prosthodontic and prosthodontic-related procedures, except as otherwise noted in this section. Prior authorization requests must meet the criteria in WAC 182-535-1220. In addition, the agency requires the dental provider to submit:

(a) Appropriate and diagnostic radiographs of all remaining teeth.

(b) A dental record which identifies:

(i) All missing teeth for both arches;

(ii) Teeth that are to be extracted; and

(iii) Dental restorative and periodontal services completed on all remaining teeth in the arch(es) being requested.

(2) Complete dentures. The agency covers complete dentures, including overdentures, when prior authorized, except as otherwise noted in this section.

The agency considers three-month post-delivery care (e.g., adjustments, soft relines, and repairs) from the delivery (placement) date of the complete denture as part of the complete denture procedure and does not pay separately for this care.

(a) The agency covers complete dentures only as follows:

(i) One initial maxillary complete denture and one initial mandibular complete denture per client.

(ii) Replacement of a partial denture with a complete denture only when the replacement occurs three or more years after the delivery (placement) date of the last resin partial denture.

(iii) One replacement maxillary complete denture and one replacement mandibular complete denture per client, per client's lifetime. The replacement must occur at least five years after the delivery (placement) date of the initial complete denture or overdenture and the replacement is medically necessary. Prior authorization is required for all replacement dentures with evidence of medical necessity.

(b) The agency reviews requests for replacement that exceed the limits in this subsection (2) under WAC 182-501-0050(7).

(c) The provider must obtain a current signed Denture Agreement of Acceptance (HCA 13-809) form from the client at the conclusion of the final denture try-in and at the time of delivery for an agency-authorized complete denture. If the client abandons the complete denture after signing the agreement of acceptance, the agency will deny subsequent requests for the same type of dental prosthesis if the request occurs prior to the dates specified in this section. A copy of the signed agreement must be kept in the provider's files and be available upon request by the agency. Failure to submit the completed, signed Denture Agreement of Acceptance form when requested may result in recoupment of the agency's payment.

(3) Resin partial dentures. The agency covers resin partial dentures only as follows:

(a) For anterior and posterior teeth only when the following criteria are met:

(i) The remaining teeth in the arch must be periodontally stable and have a reasonable periodontal prognosis.

(ii) The client has established caries control.

(iii) The client has one or more missing anterior teeth or four or more missing posterior teeth (excluding teeth one, two, fifteen, and sixteen) on the upper arch to qualify for a maxillary partial denture. Pontics on an existing fixed bridge do not count as missing teeth. The agency does not consider closed spaces of missing teeth to qualify as a missing tooth.

(iv) The client has one or more missing anterior teeth or four or more missing posterior teeth (excluding teeth seventeen, eighteen, thirty-one, and thirty-two) on the lower arch to qualify for a mandibular partial denture. Pontics on an existing fixed bridge do not count as missing teeth. The agency does not consider closed spaces of missing teeth to qualify as a missing tooth.

(v) There is a minimum of four functional, stable teeth remaining per arch.

(vi) There is a three-year prognosis for retention of the remaining teeth.

(b) Prior authorization is required.

(c) The agency considers three-month post-delivery care (e.g., adjustments, soft relines, and repairs) from the delivery (placement) date of the resin partial denture as part of the resin partial denture procedure and does not pay separately for this care.

(d) Replacement of a resin-based partial denture with a new resin partial denture or a complete denture if it occurs at least three years after the delivery (placement) date of the resin-based partial denture and is medically necessary. Prior authorization is required for all replacement dentures with evidence of medical necessity and meet agency coverage criteria in (a) of this subsection.

(e) The agency reviews requests for replacement that exceed the limits in this subsection (3) under WAC 182-501-0050(7).

(f) The provider must obtain a signed Partial Denture Agreement of Acceptance (HCA 13-965) form from the client at the time of delivery for an agency-authorized partial denture. A copy of the signed agreement must be kept in the provider's files and be available upon request by the agency. Failure to submit the completed, signed Partial Denture Agreement of Acceptance form when requested may result in recoupment of the agency's payment.

(4) Provider requirements.

(a) The agency requires a provider to bill for a removable partial or complete denture only after the delivery of the prosthesis, not at the impression date. Refer to subsection (5)(e) of this section for what the agency may pay if the removable partial or complete denture is not delivered and inserted.

(b) The agency requires a provider to submit the following with a prior authorization request for a removable resin partial or complete denture for a client residing in an alternate living facility or nursing facility:

(i) The client's medical diagnosis or prognosis;

(ii) The attending physician's request for prosthetic services;

(iii) The attending dentist's or denturist's statement documenting medical necessity;

(v) A completed copy of the Denture/Partial Appliance Request for Skilled Nursing Facility Client (HCA 13-788) form available from the agency's published billing instructions which can be downloaded from the agency's website.

(c) The agency limits removable partial dentures to resin-based partial dentures for all clients residing in one of the facilities listed in (b) of this subsection.

(d) The agency requires a provider to deliver services and procedures that are of acceptable quality to the agency. The agency may recoup payment for services that are determined to be below the standard of care or of an unacceptable product quality.

(5) Other services for removable prosthodontics. The agency covers:

(a) Adjustments to complete and partial dentures three months after the date of delivery.

An additional reline or rebase may be covered for complete or partial dentures on a case-by-case basis when prior authorized.

(d) Laboratory fees, subject to the following:

(i) The agency does not pay separately for laboratory or professional fees for complete and partial dentures; and

(ii) The agency may pay part of billed laboratory fees when the provider obtains prior authorization, and the client:
