Contractors to Process Noncovered Ambulance Services for COB
The Centers for Medicare & Medicaid Services (CMS) has instructed contractors to revise their claims processing systems to allow HCPCS Level II codes identifying noncovered ambulance transportation and transportation-related services into their systems for adjudication. Although these codes (A0021-A0424 and A0998) remain noncovered, accepting these claims will allow providers and suppliers to obtain a Medicare denial so that they may then submit a claim for a patient with Medicare to his or her secondary insurance for coordination of benefits (COB) purposes.
Providers and suppliers should begin submitting ambulance transportation and transportation-related service claims beginning Jan. 1, 2012. Providers and suppliers billing for noncovered ambulance services for the purpose of a Medicare denial should append modifier GY to the appropriate HCPCS Level II code for the service.
