Federally Qualified Health Centers: Sliding-Scale Care, and How Imaging Really Works

FQHCs are the backbone of low-cost primary care in the US. If you need an MRI on a low income, understanding what a health center can and cannot do saves you weeks of wrong turns. Here is the system, from the federal rules down to the referral desk.

What an FQHC is

Health centers are local clinics treating “medical, dental, mental health, substance use, and other health care needs”, in HRSA's own definition. To receive federal funding they must be community-based and led in part by patients (a majority of the governing board must be patients), serve everyone even if they cannot pay, and adjust fees based on income and family size. HRSA reports that about 90 percent of health center patients have incomes below 200 percent of the federal poverty level.

The legal foundation is Section 330 of the Public Health Service Act (42 USC 254b), which defines a health center as an entity serving a medically underserved population and lists the required primary health services every center must provide, a list that includes “diagnostic laboratory and radiologic services”. That phrase matters for imaging, and we come back to it below.

How the sliding fee scale works

The sliding fee discount program is a compliance requirement, not a courtesy. Chapter 9 of HRSA's Health Center Program Compliance Manual requires that no patient be denied service due to inability to pay, and that eligibility for discounts be assessed “based only on income and family size” against the current federal poverty guidelines (FPG).

Each health center builds its own schedule inside those federal rails, so the exact fee for a visit varies by center. Eligibility paperwork is typically proof of income and household size; centers must have board-approved policies defining both.

What imaging FQHCs actually provide

Section 330 puts “diagnostic laboratory and radiologic services” on the required services list, but Chapter 4 of the HRSA Compliance Manual allows every required service to be delivered one of three ways: directly by the center's own staff, through a formal contract with a third party, or through a formal written referral arrangement. A service being “required” does not mean there is a machine on site.

In practice, health centers are primary care clinics. Basic diagnostics are often in-house or contracted nearby; an MRI machine is a multi-million-dollar installation that sits at hospitals and dedicated imaging centres, so MRI is almost always the formal-referral column. HRSA's rules require those referral arrangements to be managed ones: the center must track the referral and get results back for your follow-up care.

How to use an FQHC when you need an MRI

1. Find a center and register

   Use findahealthcenter.hrsa.gov, enter your ZIP code, and call the nearest site. Ask how to register as a new patient and what documents the sliding fee assessment needs (proof of income and household size are standard).

2. Book the sliding-fee visit

   A clinician examines you and decides whether MRI is warranted. If it is, they write the imaging order. This visit is what the sliding fee discount applies to.

3. Ask where they refer, and what it costs there

   Ask which imaging providers the center refers to, whether any offer discounted rates for referred health-center patients, and whether the receiving hospital has a financial assistance policy. Centers make managed referrals, so the desk usually knows the local landscape.

4. Price the scan before you book it

   Compare the referred facility's self-pay quote against RadiologyAssist (from $265 all-inclusive, retrieved August 2026) and local cash rates. The order is portable: you can take it to whichever accredited facility you choose.

5. Route the results back

   Make sure the imaging facility sends the report to your health center, which is required to follow up with you on the results as part of the referral arrangement.
