Illinois Medicaid home health billing — statistical anomalies in provider data.
Every entity in this report was identified through statistical anomaly detection on billing data alone. No demographic, geographic, or name-based criteria were used in selection. The names, owners, and addresses of flagged entities were retrieved after identification — not before.
How we found them:
Data sources: Illinois Medicaid Billing Data — Released by DOGE/HHS, February 2025. Cross-referenced with NPPES NPI Registry, OIG LEIE. All figures represent Medicaid allowed amounts.
Illinois Medicaid paid $1.9 billion to 1,788 home health providers. Six billing codes account for the bulk of it. Each code represents a nurse or aide showing up at someone's home.
T1000 = LPN/RN home health visit (~$80M+ from Verbeck alone). T1002 = RN services, up to 15 min. T1003 = LPN/LVN services, up to 15 min. S5130 = Homemaker services ($139M total, 70 providers). G0299 = Skilled nursing home health ($111M). T1021 = Home health aide per visit ($63M). Each claim represents a person supposedly traveling to a patient's home.
Some operators don't run one home health company — they run six. By fragmenting across multiple NPIs, they spread billing across entities while controlling everything from the top.
Each NPI (National Provider Identifier) bills Medicaid independently. If one NPI gets flagged for high volume, the others keep billing. It also makes the total billing harder to see — you'd need to connect the dots across entities to find the $109 million.
6 NPIs · Advantage Nursing Services · Primary code: T1000 (LPN/RN per visit)
236,069 claims of T1000 from the main NPI alone. That's LPN/RN home visits. At $79.2M billed, that averages $335 per visit. The satellite NPIs are growing at 4,000-9,000% — new entities spinning up fast while the main one keeps billing.

Growth rates that defy physics. Here are the providers with anomalous billing patterns.
$20.3M in T1002/T1003 = approximately 39,000 fifteen-minute visit units. Peak month: $1.13M = ~2,100 visits. At 20 working days, that's 70 visits/day. Each visit requires a licensed nurse to physically travel to a patient's home, provide care for 15 minutes, document it, and drive to the next one. Seventy times. Every day.
Peak month: $323K = ~600 fifteen-minute visits = 30 visits/day. Starting from zero in 2020.
Every number in this report comes from Illinois Medicaid's own billing records. The addresses are public. The growth rates are in their database. The math doesn't work — and it's been sitting there for years.
1,788 providers. $1.9 billion. Zero sanctions.
The data is in the public record. The growth rates are in the billing records. Nobody's looking.
