Dual-eligible (Medicare + AHCCCS) dental questions in Arizona

If you have both Medicare and AHCCCS in Arizona, your dental coverage is split between two programs with different rules. Learn how to coordinate your benefits and find care.

Understanding your dual coverage

If you have both Medicare and AHCCCS in Arizona, you are “dual-eligible.” Each program has its own dental rules, and they do not automatically coordinate. Understanding what each covers (and doesn’t) helps you plan care and avoid surprise bills.

Medicare and dental

Original Medicare does not include routine dental services such as cleanings, fillings, crowns, or extractions. If you are enrolled in a Medicare Advantage plan, that plan may offer some dental benefits. Coverage varies widely—some plans include preventive care only; others cover more extensive work.

To learn what your Medicare plan covers:

• Call the phone number on your Medicare card.
• Ask specifically about dental coverage (cleanings, exams, fillings, major work).
• Ask for a summary of benefits and coverage (it will list what’s included and any limits).

See our guide Does Medicare Cover Dental Care? for more detail.

AHCCCS and dental

AHCCCS (Arizona’s Medicaid program) does provide dental benefits to eligible members. Coverage includes preventive care and, depending on your plan, may also include restorative or major services.

To learn what your AHCCCS plan covers:

• Visit www.azahcccs.gov or call your AHCCCS plan directly.
• Ask which dentists or dental networks participate in your plan.
• Request a list of covered services (preventive, restorative, orthodontia, dentures, etc.).
• Ask about any waiting periods, annual maximums, or referral requirements.

See our guide AHCCCS Dental Coverage in Arizona for details specific to Arizona’s Medicaid programs.

Coordination of benefits

When you have both programs, the rules for “coordination of benefits” determine which plan pays first and whether the second plan pays anything. These rules are technical and vary based on your specific plan types, age, and whether you are in an institution.

Do not guess. Before scheduling a dental procedure:

1. Tell your dentist’s office that you have both Medicare and AHCCCS.
2. Call your Medicare plan and ask: “If I have a dental procedure, who should file the claim first—you or my AHCCCS plan?”
3. Call your AHCCCS plan and ask the same question.
4. Ask both plans whether any out-of-pocket costs (copays, coinsurance) apply.
5. Ask your dentist to verify coverage with both plans before treatment begins.

Misaligned claims can delay payment and create confusion. Clearing this up in advance protects you.

Finding dental care

Not all dentists accept both Medicare and AHCCCS. Some accept only one program; others accept neither and operate on a cash-pay basis.

When searching for a dentist:

• Call your AHCCCS plan and request a list of participating dentists.
• If you are on a Medicare Advantage plan with dental benefits, get that plan’s dental network list as well.
• Ask the dentist’s office directly: “Do you accept both my Medicare plan and my AHCCCS plan?”
• Ask if the office verifies coverage with both plans before scheduling.

Questions to ask your plans

• Which dentists do you cover in my area?
• What specific services are covered at no cost (preventive)?
• What services require a copay or coinsurance?
• Is there an annual maximum benefit dollar amount?
• Do I need a referral from a primary-care provider?
• How do you coordinate benefits if I have another insurance plan?
• What is your appeals process if a claim is denied?
