A farmworker mobile program needs a funding plan that accounts for uninsured visits. In 2022, 53% of hired crop workers were uninsured, about five times the rate for all nonelderly adults. Billing alone may not cover the program's costs.
Farmworker mobile programs are funded by braiding several sources: Section 330(g) Migrant Health Center grants or other health center funds, Medicaid and CHIP billing for patients who have coverage, sliding fee collections, state farmworker health programs, foundation grants, and in-kind or cash support from agricultural partners. The work is in matching each source to the costs it can cover and documenting the result well enough to renew.
Start with the payer mix you will have
Before choosing grants, estimate who the patients will be and how they will pay. The 2022 National Agricultural Workers Survey analysis found 53% of hired crop workers uninsured. That survey does not describe the exact payer mix of your route, which may also serve children and other family members. Use local data to set the budget.
Coverage can differ between workers and family members, including children. Do not assume eligibility from age, citizenship, or work setting alone. Estimate the mix of eligible patients and uninsured visits using local enrollment data and current state rules.
Medicaid eligibility narrowed on October 1, 2026
The 2025 federal reconciliation law changed coverage for some immigrant patients. Starting October 1, 2026, federally funded Medicaid and CHIP are limited to lawful permanent residents (green card holders), Cuban and Haitian entrants, people living in the U.S. under Compacts of Free Association, and, in states that elect the option, lawfully residing children and pregnant people. Refugees and asylees without green cards, among other groups, lose eligibility. Undocumented immigrants were already ineligible for federally funded coverage, apart from Emergency Medicaid.
Subsidized ACA Marketplace coverage narrows to the same core groups on January 1, 2027. Other lawfully present immigrants, a category that includes H-2A guest workers, will be able to buy Marketplace plans only at full price.
For a farmworker program, these changes may increase uninsured visits and demand for sliding-fee discounts, but the effect depends on the state and patient mix. Model scenarios and keep enrollment assistance available for patients who remain eligible. Check current rules when updating registration practices.
Section 330(g) is the anchor for health centers that have it
Migrant Health Center funding under Section 330(g) is the federal stream built for this population. These grants support care and enabling services such as outreach and interpretation, subject to each award's terms. Health centers can use HRSA's current program data when preparing a budget or application.
Health centers without 330(g) funding can still serve agricultural workers with community health center (330(e)) funds and report them in the Uniform Data System. HRSA awards 330(g) funding through periodic service area competitions, so a health center building a farmworker track record today is better positioned when its area next opens. Our explainer on what a Migrant Health Center is covers the definitions and scope rules.
A health center should review HRSA's Form 5B site instructions and obtain required scope approval for a mobile clinic before service begins. Federal Tort Claims Act coverage depends on more than site listing; confirm coverage with the health center's compliance and legal teams.
Billing still matters
Bill eligible visits under the applicable payer rules. Medicaid payment for health centers may use a prospective payment system or an approved alternative, but rates vary by state, service, and contract. Medicare, CHIP, and private insurance may cover some patients.
Eligible health centers may use the 340B Drug Pricing Program for qualifying prescriptions. The pharmacy team should confirm patient eligibility, dispensing arrangements, and payer rules before planning medication supplies for patients who move.
State programs, foundations, and local grants fill gaps
Several states fund farmworker health directly or through state offices of rural health and primary care associations. Some state-funded coverage programs also cover immigrants who lose federal Medicaid eligibility, though KFF notes several states have recently scaled back or capped those programs because of budget pressure. Check your state's current status.
Foundations with health equity, rural health, or food system missions may fund farmworker outreach, startup costs, clinic equipment, or a pilot season. USDA Rural Development's Community Facilities program may help eligible rural organizations finance facilities and equipment. Check the current program rules for your project.
Agricultural partners can contribute more than access
Growers and grower associations benefit from a healthy workforce, and many will contribute. Common forms include a host site with power and restrooms, sponsorship of a clinic night, help announcing clinics to crews, and funding for a seasonal program. These arrangements range from formal sponsorships to informal understandings. Workers trust the clinic more when clinical operations and patient information stay with the health center. Our post on earning trust in farmworker communities covers that separation.
Budget for the costs that make the program work
Grantwriters sometimes budget a farmworker program like a weekday mobile clinic. The costs differ. Include:
- Evening and weekend staffing for a dedicated mobile crew, including differentials
- Indigenous-language interpretation in addition to bilingual staff
- Promotores for outreach and follow-up
- Occupational health supplies for heat illness and pesticide exposure
- Bridge medication supplies and care coordination for patients who move
- Seasonal route changes, including fuel and longer drive times at peak

Quick answers
What federal funding exists for farmworker health care?
Section 330(g) of the Public Health Service Act funds Migrant Health Centers. Health centers may also use other eligible Health Center Program funds for agricultural worker care.
How did Medicaid eligibility change for immigrants in October 2026?
Starting October 1, 2026, federally funded Medicaid and CHIP are limited to green card holders, Cuban and Haitian entrants, COFA migrants, and, at state option, lawfully residing children and pregnant people. Refugees and asylees without green cards are among those losing eligibility.
Can growers fund a farmworker clinic?
Yes. Growers often provide host sites, sponsor clinic nights, or help fund a season. Clinical operations and patient information stay with the health center.
