Hours billed per day
Medicaid billing converted into hours of hands-on care per day. The lower bound counts one unit per claim line and needs no price; the other two divide dollars by a unit price, the conservative one at 1.5 times the price. The clinician on the claim may be a supervisor under state rules, so billing organizations are counted too.

Procedures billed
The specific codes behind the dollars. Medicaid figures come from T-MSIS (2018 to 2024) and are compared with every other provider billing the same code; Medicare figures come from the 2024 physician and supplier file and compare this provider's submitted charge with what Medicare allowed, against the usual ratio for that code.
