Monitor payer policy activity
Defines covered adult dental services and basic limits for Hawaii Medicaid adults age 21 and older, and explains referral resources and prior authorization applicability. Affects Medicaid providers, dentists, FQHCs, and related clinics in Hawaii.
Adult dental benefits (preventive, restorative and some denture benefits) were approved and take effect January 1, 2023 for Medicaid adults aged 21 and older.
Covered Services and Limits
Covered Services and Frequency Limits
Covered adult dental benefits (some limits and prior authorization may apply):
Coverage depends on medical necessity; limits may be exceeded with prior approval to determine medical necessity.
The memo notes that explicit cosmetic-only exclusions are not listed. Coverage for procedures that might be considered cosmetic is therefore contingent on medical necessity and subject to the stated frequency and prosthodontic limits (for example, denture replacement of 1 every 5 years). The memo also states that these limits may be exceeded only with prior approval to determine medical necessity, so any request outside the published limits requires documentation and prior authorization review.
Coverage of adult dental services is conditional: the memo specifies that, like any medical benefit, coverage will depend on the medical necessity of each case. Services determined to be not medically necessary for an individual patient are not covered. Requests for services beyond published limits must be supported by documentation demonstrating medical necessity and may require prior approval.

Prior Authorization, Documentation, and Billing Actions
Prior authorization may be required to exceed limits
Some limits in this policy require prior approval; services that exceed stated frequency limits may be covered only with prior authorization to determine medical necessity. Providers should request prior approval when they intend to exceed the limits listed for covered services.
- Policy: “These limits may be exceeded based upon prior approval to determine medical necessity.”
- Examples of limits that may require prior approval include frequency limits (e.g., comprehensive oral evaluation once every 5 years; prophylaxis 2 per year; dentures 1 every 5 years).
Referral and member assistance via CCMC
Refer patients or questions about adult dental benefits to Community Case Management Corporation (CCMC) for assistance with benefit explanation, locating a dentist, or coordinating transportation for travel from neighbor islands to Oahu.
- CCMC contact: 808-792-1070 or toll-free 1-888-792-1070 (available beginning January 2023).
Use Chapter 14 codes and keep medical necessity records
Follow Chapter 14 of the Provider Manual for dental procedure codes and retain documentation supporting medical necessity when requesting prior approval for services beyond stated limits.
- Provider Manual reference: https://medquest.hawaii.gov/en/plans-providers/fee-for-service/provider-manual.html
- Maintain clinical records that justify medical necessity for any request to exceed frequency or other limits.
Risk of denial when limits exceeded without prior approval
Services provided more frequently than the listed limits risk denial unless prior approval documents medical necessity; coverage is determined case-by-case based on medical necessity.
- Policy statement: “Like any medical benefit, coverage will depend on the medical necessity of each case.”
- Example limits subject to this rule: comprehensive oral evaluation once every 5 years; scaling and root planing one every 24 months; complete dentures one every 5 years.
