Tier flag ≠ dollar rank
MACPAC adult-dental tier is not the uncovered-basket rank. Hawaii (limited) models $54,042 of uncovered work (#1 of 51), higher than Delaware none-tier at $51,300, because the join prices uncovered codes at that state's private level. Iowa (extensive) is the floor at $12,065 (4.5x).

Jurisdictions by adult Medicaid dental tier

Adult dental services are an optional Medicaid benefit. Pediatric dental coverage is federally required (under EPSDT), so every state covers comprehensive dental services for Medicaid-enrolled children and teens. For adults (age 21+), each state chooses what, if anything, to cover.
The MACPAC coverage tiers
The Medicaid and CHIP Payment and Access Commission (MACPAC) categorizes each state's adult Medicaid dental coverage into one of four tiers:
- Extensive coverage (19 in this file). Broad adult dental services - diagnostic, preventive, restorative, endodontics, oral surgery, periodontics, and prosthodontics. Some extensive states still apply an annual dollar cap.
- Limited coverage (21 in this file). Typically diagnostic, preventive, and basic restorative. Crowns, molar root canals, and dentures may need prior authorization or sit outside the benefit.
- Emergency only (10 in this file). Extraction for acute pain or infection, and little else for adults.
- No adult coverage (1 in this file: Delaware). No adult dental benefit beyond medically necessary hospital settings.
Why the same state can change tiers
State Medicaid budgets are negotiated each year, and adult dental is a common expansion or cut lever. Always check your state's current Medicaid handbook for the operative coverage policy when planning treatment.
The "covered" trap: finding a Medicaid dentist
Coverage on paper isn't the same as access in practice. State Medicaid programs often reimburse dentists well below private-market fees for the same CDT, so networks can be thin.
