This blog post is part of a series that addresses ambulance billing best practices. Our ambulance billing blog series highlights tips and insights to help you improve ambulance billing efficiency, lower ambulance claim rejections, and get reimbursed faster. Why is the Physician Certification Statement (PCS) for non-emergency ambulance services so challenging for EMS billing? The challenge is real because you have to rely on the facility requesting the non-emergency ambulance services to make sure the PCS is filled out properly by the right person and on-time. It helps when your EMS Dispatch/Intake staff have a good relationship with the facilities and can collect the PCS before the crew leaves the station, but even then, there can be obstacles when individuals coordinating the non-emergency ambulance transport don’t have a clear understanding of why or when a PCS is required.
