SMART Act Ambulance Services

Problem:

As a result of an administrative rule change, the reimbursement rates to ambulance providers were changed effective with dates of service 07/01/13. In addition, the SMART Act 2.7% reimbursement rate reduction no longer applies to ambulance services. Since the rule affected reimbursements already made to providers for dates of service back to 07/01/13, HFS has underpaid providers.
