Questions for Medicare EDI Services? If you are a vendor with questions, or a health care professional interested in becoming an electronic biller, feel free to drop us a note. One of our EDI Analysts will be glad to contact you, typically via telephone.

This is not a secured page so we encourage you not to use this form to ask claim specific questions or any other question that contains claim numbers, HIC numbers, provider numbers, or Social Security numbers. Please note that we are not able to use the internet/email to reply to inquiries in the event that Protected Health Information such as HICNs for example is required during the construction of the response per instructions from the Centers for Medicare and Medicaid Services (CMS).

Please keep in mind, this is not the place for vendors, physicians or health care professionals to send questions regarding Medicare claims. If you have questions regarding claims, call our Provider Services department. Thank You.

Please note: electronic mail is not necessarily secure against interception. If your communication is very sensitive, or includes personal information, you may want to send it by postal mail instead.
