Our Methodology
Private insurance refers to any kind of healthcare coverage that isn't from the state or federal government. This includes individual and family plans offered by an employer or purchased from the Insurance Marketplace. Every plan will have different requirements and out of pocket costs so be sure to get the full details before you start treatment.
Self-pay involves paying for treatment out of your own pocket. You can use savings or credit, get a personal loan, or receive help from family and friends to fund your treatment. If you don't have insurance or your insurance plan doesn't cover a specific program, self-pay can help ensure you still get the care you need.
Financial aid can take many forms. Centers may have grants or scholarships available to clients who meet eligibility requirements. Programs that receive SAMHSA grants may have financial aid available for those who need treatment as well. Grants and scholarships can help you pai for treatment without having to repay.
Medicaid is a state based program that helps lower-income individuals and families pay for healthcare. Medicaid covers addiction treatment so those enrolled can use their coverage to pay for rehab. When a program accepts Medicaid the client often pays very little or nothing out of their own pocket.
