Ambulance Rate Changes Update – Second Batch


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.

Resolution for Impacted Claims:

Approximately 300K claims with dates of service on or after July 1, 2013 will be adjusted as a result of the rate increase. The department is processing the adjustments in batches as some of the claims require additional review. The first batch of adjustments was submitted June 23, 2014.

The second batch of adjustments includes approximately 10K claims that were submitted on July 11, 2014. The second batch of adjustments includes the remaining claims billed under category of service 50 with procedure codes A0422, A0425, A0427, A0428, A0429, A0431, A0433, A0434.

The department continues to work through remaining claims with category of service 51. All providers should verify their mileage. Please continue to access this site for updated announcements.
