Which document primarily drives reimbursement decisions in OT services?

• A. Plan of Care (POC).
• B. Referral letter.
• C. Initial intake form.
• D. Discharge summary.

Answer: (A)

In OT reimbursement, the essential driver is a plan that clearly justifies ongoing services and outlines exactly how care will be delivered. The Plan of Care is the document that does this: it summarizes the initial evaluation findings, states specific, measurable goals, and describes the chosen interventions, along with the anticipated frequency and duration of therapy. It ties directly to medical necessity and provides the framework used for service delivery, coding, and billing. Payers review and rely on this plan to authorize continued services and to determine whether care should continue, be modified, or stop.

Other documents play important roles at different points, but they don’t steadily justify ongoing reimbursement. A referral letter simply requests services and doesn’t provide the detailed justification or a long-term course of care. An initial intake form collects background information but doesn’t lay out a formal, billable plan. A discharge summary shows what was accomplished and the outcomes after services are done, not the ongoing justification for ongoing visits. The Plan of Care is the living, central document that guides and sustains reimbursement.
