Does it matter where protocol services are performed and how the place of service is reported on a claim?Yes. When scheduling a study protocol visit encounter in CareConnect, it is critical to select the location where the services will actually be performed. Otherwise, claims may report an incorrect place of service code. Claims for billable study protocol items/services, just as any other claim, must accurately reflect the service location. Reimbursement may differ depending on the place of service (e.g., 11=doctor’s office vs. 22=hospital out-patient). Reporting an incorrect place of service code can result in an overpayment or underpayment.
