WA HB2522

Requires dental-only health plans to cover preventive dental services as determined by the treating dentist, without imposing age restrictions or frequency limitations

Mandates that when carriers require an adjunctive service for reimbursement of a separate preventive service, they must reimburse providers for both services

Defines covered preventive dental services to include prophylaxis, fluoride varnish, sealants, oral hygiene instruction, silver diamine fluoride, nano-hydroxyapatite, preventive resin restoration, and oral cancer screenings

Applies to health carriers, health care service contractors, limited health care service contractors, and disability insurers offering dental-only coverage

Responds to federal actions proposing restrictions on fluoride access and private insurers limiting preventive care coverage despite available patient benefits
