How the Sliding Fee Scale Works at Free Clinics
No insurance? Low income? Here's exactly how FQHCs calculate what you pay — and how to prepare for your first visit.
If you're uninsured or underinsured, the sliding fee scale at a Federally Qualified Health Center (FQHC) can make the difference between getting care and going without. Here's exactly how it works.
What Is the Sliding Fee Scale?
The sliding fee scale is a federally required discount program at FQHCs. It adjusts what you pay based on your household income relative to the federal poverty level (FPL). The lower your income, the less you pay — down to $0 for the lowest-income patients.
FQHCs are legally required to have this program. If a clinic doesn't offer a sliding fee scale, it's not an FQHC.
How Is the Fee Calculated?
Your fee is based on two factors: household income and family size.
| Income Level | Typical Fee |
|---|---|
| ≤100% FPL | $0–$20 per visit (nominal fee) |
| 101–150% FPL | ~$20–$40 per visit |
| 151–200% FPL | ~$40–$80 per visit |
| >200% FPL | Full cost or insurance billed |
For reference, 100% FPL in 2025 is approximately $15,650 for a single person and $32,150 for a family of four.
These are general ranges — each FQHC sets its own fee schedule within federal guidelines. Always confirm the specific fees when you call.
What Counts as Proof of Income?
Most FQHCs accept any of the following:
- Recent pay stubs (last 30–60 days)
- Most recent federal tax return
- Social Security, disability, or pension award letters
- Unemployment benefit statements
- **Self-attestation** — a written statement of your income
That last one is key. If you have no formal documentation, you can write a brief statement saying so. Most FQHCs will accept this and charge the nominal fee or $0.
What If I Have No Income at All?
Tell the clinic. FQHCs are not allowed to turn away patients for inability to pay the sliding fee. They can waive the fee, defer payment, or set up a payment plan. You will not be sent to collections over a $20 visit fee.
What About Dental and Mental Health?
The same sliding fee scale applies to dental and mental health services at FQHCs — not just primary care visits. A dental cleaning that costs $150–$200 at a private dentist may cost $20 at an FQHC on the sliding scale.
Do I Need to Reapply Every Visit?
No — most FQHCs set your income level at enrollment and update it annually. You'll recertify roughly once a year, or if your income changes significantly.
Bottom Line
The sliding fee scale exists specifically for people who can't afford regular healthcare. Don't let uncertainty about paperwork stop you from going. Show up, tell them your situation, and let the clinic's financial counselor walk you through it.
