What the words on these cards mean4
- SAMHSA’s National Directory
- SAMHSA’s yearly list of treatment facilities, from each facility’s own answers to SAMHSA’s survey. In SAMHSA’s words: “SAMHSA does not regulate substance use or mental health treatment programs or facilities.” A listing isn’t an inspection, a licence or a rating; a facility’s state keeps those. Source: SAMHSA, National Directories 2025.
- Sliding fee scale
- SAMHSA’s definition: “Variable prices for services based on a person’s ability to pay.” SAMHSA’s name for it: “Sliding fee scale (fee is based on income and other factors)”. Source: SAMHSA, National Directories 2025, code reference.
- Payment assistance
- SAMHSA’s definition: “A program which helps low-income, uninsured, or underinsured patients who need help paying for all or part of their medical bills.” SAMHSA adds: check with the facility for details. Source: SAMHSA, National Directories 2025, code reference.
- Not listed
- The directory doesn’t list this for the place: the facility didn’t report it. It isn’t a no: call the place to ask. Source: How this site reads each directory.
