Medicaid Pays for the School Nurse. Two-Thirds of Schools Still Don't Have One Full Time.

Medicaid is best known as health insurance.▸ Inside public schools it also functions as a payroll line: districts bill the program for the nurses, counselors, and therapists they already employ, and use the reimbursement to keep the positions staffed. Until 2014, that billing was narrow — limited to services written into a student's individualized education program. That year CMS clarified the rule so states could bill for medically necessary care delivered to any Medicaid-enrolled student, not just those with a disability plan — and school Medicaid claiming has grown since. It is now, by Healthy Schools Campaign's reading of federal spending data, an estimated $8 billion-a-year stream — and still an undercount, since the federal reporting it draws on only tracks services tied to a disability plan. None of that has closed the gap in who is actually on staff.

School Medicaid billing is optional, LEA by LEA, and participation varies enormously.▸ The share of local education agencies that bill Medicaid for direct services ranges from 10% in Wyoming to 100% in states such as Florida, Hawaii, Illinois, and Vermont, per the Medicaid and CHIP Payment and Access Commission (MACPAC), the nonpartisan federal body that advises Congress on the program. A district that doesn't bill isn't necessarily a district without health needs — it's often one without the administrative capacity to run a Medicaid claiming operation on top of running a school.

One-time pandemic relief papered over some of that gap for a few years.▸ CMS's own accounting, comparing March 2023 staffing to the pre-pandemic baseline, found school social worker counts up 48%, school nurse counts up 42%, and counselor and psychologist counts each up 10% — funded substantially by temporary COVID relief money. That money is gone: the $122 billion ARP ESSER fund that helped pay for it had to be obligated by September 2024, with final liquidation deadlines running out through early 2026. What's left to fund these positions going forward is the recurring stream: Medicaid.

That recurring stream is not insulated from what happens to Medicaid overall.▸ Congress's 2025 reconciliation law restricts several of the financing tools states use to fund their share of the program — including a moratorium on new or increased provider taxes, one of the mechanisms states lean on to cover the non-federal match behind their Medicaid budgets, school claiming included. School-based Medicaid doesn't have its own protected line item; it rides on the same state budgets that financing squeeze reaches first.

Even with billions flowing and staffing up double digits during the ESSER years, the baseline school nursing workforce remains thin.▸ A National Association of School Nurses-led study published in the Journal of School Nursing — the National School Nurse Workforce Study 2.0 — estimated 78,869 full-time equivalent school nurses working in U.S. public schools in 2024: 65,052 registered nurses and 13,817 licensed practical or vocational nurses. Measured against the 49.5 million students enrolled in U.S. public schools in fall 2023, per the National Center for Education Statistics, that works out to roughly one FTE nurse for every 628 students nationwide — a BlackLeaf calculation combining the two federal and academic counts, not a figure either source states directly.

Nationally, only an estimated 65% of public schools employ a full-time nurse, per NASN data reported by Education Week — and that average masks a wide regional spread.

The West trails every other region by a wide margin — 33.3% full-time coverage against 88.2% in the Northeast — and the same reporting found rural schools well behind urban ones, 56.2% to 70.3%.▸ Money that flows through a state's general Medicaid claiming apparatus doesn't correct for that unevenly by itself; it flows fastest to the districts that already have the staff and billing infrastructure to draw it down.

Dollar and staffing figures describe distinct data collections spanning 2023–2024 and are not directly additive; the $8 billion Medicaid figure is Healthy Schools Campaign's estimate from federal spending data and is described by that organization itself as an undercount.
