Person-Centered Planning: ISP, Plan of Care, and What They Require

Person-centered planning is the process of building a service plan around the individual’s own goals, preferences, and choices — not around what’s convenient for the system. It’s the foundation of Medicaid home and community-based services, required by federal rule, and the document it produces — usually called an Individual Support Plan (ISP) or Plan of Care (POC) — is the single most important record in a person’s file.

For providers, the plan isn’t paperwork you file and forget. It’s the authorization for what you deliver, the standard you’re audited against, and the thing every claim ultimately traces back to.

What is person-centered planning?

Person-centered planning is a required approach under the CMS HCBS rules. It means the planning process is directed by the individual (with the people they choose to involve), reflects their goals and preferences, offers real choices among services and providers, and documents the individual’s strengths and needs. It’s the practical expression of the rights guaranteed by the HCBS Settings Rule.

ISP vs. Plan of Care vs. IPC — what’s the difference?

These terms cause a lot of confusion because states use them differently for essentially the same idea: the written plan that results from person-centered planning.

• Individual Support Plan (ISP) — common in IDD waiver programs; emphasizes supports, goals, and outcomes.
• Plan of Care (POC) — common across HCBS and home health; emphasizes authorized services and clinical needs.
• Individual Plan of Care (IPC) — used in some states/waivers as the specific authorizing document.

The label varies; the function is the same. It defines who the person is, what they need, what services are authorized, in what amount, and toward what goals.

What must the plan contain?

Under federal person-centered planning requirements, the plan generally must:

• Reflect the individual’s goals and preferences and be directed by them.
• Identify the services and supports authorized, including amount, frequency, and duration.
• Document assessed needs and how services address them.
• Include the individual’s choice of providers and settings.
• Address health and safety risks and any rights modifications (which must be justified, time-limited, and reviewed).
• Be reviewed and updated at least annually, or when needs change.

Why the plan drives everything downstream

The plan is the hub the whole operation runs on:

• Services — you deliver what the plan authorizes, no more and no less.
• Documentation — service notes and logs must map back to the plan’s goals and authorized services.
• Billing — every unit billed has to trace to an authorized service in the plan. Bill outside it and the claim denies or is clawed back.
• Audits — reviewers compare what you documented and billed to what the plan authorized.

How the right system keeps the plan at the center

When the plan lives in one system and service delivery lives in another, drift is inevitable — notes that don’t match goals, services delivered beyond authorization, plans that lapse past their review date. That drift is exactly what audits catch.

Statewise keeps the person-centered plan connected to everything: documentation, authorizations, and billing all reference the same plan, with review dates tracked and records kept audit-ready against each state’s rules. See the IDD platform or the platform overview.

Frequently asked questions

What is person-centered planning in HCBS?

A federally required process that builds a person’s service plan around their own goals, preferences, and choices, directed by the individual and the people they choose to involve.

What’s the difference between an ISP and a Plan of Care?

They’re largely the same document under different names. An Individual Support Plan (ISP) is common in IDD programs and emphasizes supports and outcomes; a Plan of Care (POC) is common in HCBS/home health and emphasizes authorized services. States use the terms differently.

How often must a person-centered plan be reviewed?

Federal requirements call for review at least annually, and whenever the individual’s needs or circumstances change.

Why does the plan matter for billing?

Because every billed service must be authorized in the plan. Claims for services that aren’t in the plan — or exceed authorized amounts — are denied or recovered on audit.
