Additionally, the comment letter from the American Medical Association (AMA) detailed the potential complications of incorporating UDIs into insurance claims, including the fact that patients frequently switch health plans, the possibility that linking a device UDI to a payer could make it hard for clinicians to access that information, the potential for negative impacts on timely payments, and the significant time and expense burden associated. The AMA instead wants to see efforts directed toward adding UDIs to patient EHRs.
