- Records needed.
- Medicaid dollars per patient on code 99203 ($217 per patient-month) sit in the top 5% of every provider billing that code.

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.
