An individual support plan is the document that says what Medicaid will pay for. It names goals, the services, the amount and frequency, and the provider or the self-directed worker. States abbreviate it ISP. They also say individual service plan, individualized service plan, or person-centered service plan. The initials travel better than the exact words. If a family says "the plan," this is usually the one.
The plan is the product person-centered planning is supposed to produce, written by or with a supports coordinator. Billing is supposed to match it. An agency that delivers a service the plan does not authorize, or more units than it lists, has a documentation problem even when the support was what the person wanted that day. The correction is an updated plan, not a richer progress note.
A behavior support plan may be attached when behavior is part of the support. It does not replace the ISP. Neither does a medical plan of care from a physician. Those documents can constrain the week. The waiver plan is what opens the units on the fee schedule.
Readers should treat the amount column as the story. "Receives day habilitation" is not the same fact as "receives day habilitation for six hours, four days a week, from this agency." Rate cuts and hour cuts show up in that column, sometimes while the goal statement stays cheerful and unchanged.
Names vary, and so does who signs. The person, a guardian, the coordinator, and the provider may all have a signature line. A signature is not the same as agreement about staffing. The plan can be fully signed and still have no one to work the shift.
Review dates matter. Waivers require the plan to be revisited on a cycle, often annually, and sooner when life changes. A plan that is current on paper and a year out of date in the house is a coordination failure, not a vocabulary problem.
