Program overview

New Mexico Medicaid, administered through the state's Centennial Care program, provides comprehensive health coverage for eligible residents including medical, dental, behavioral health, and long-term care services. The program serves over 800,000 New Mexicans and is managed through four health plans: Blue Cross Blue Shield, Molina Health Care, Presbyterian Health Care, and UnitedHealthcare Community Plan.

To qualify for New Mexico Medicaid, adults under 65 can have household incomes up to 138% of the federal poverty level thanks to Medicaid expansion. Pregnant women qualify with incomes up to 255% of poverty, while children aged 0-5 can qualify with household incomes up to 305% of poverty and children aged 6-18 with incomes up to 245% of poverty. Seniors 65 and older, individuals who are blind, or those with disabilities may also qualify with both income and asset limits.

The program covers essential medical services, prescription drugs, hospital care, preventive care, mental health and substance abuse treatment, and long-term care services including nursing home care and home and community-based waiver services. Native American members have additional options including traditional healing practices and the choice to remain in fee-for-service rather than selecting a managed care organization.

When applying, gather all required documentation including citizenship verification, Social Security cards, income proof, and asset information. Applications are processed within 30-45 days, and you'll receive notification about your eligibility status and managed care plan selection. Contact the Consolidated Customer Service Center at 1-800-283-4465 with questions about your application or benefits.
