You are an “Existing Client” if you have a MBA or HSA account number.  The 6-digit account number may be found on your bill or online through the hsainsurance.com website.

You are a “New Client” if you do not have a MBA or HSA Account number.  

For questions on the amount of your payment please contact MBA/HSA’s Customer Service: (781) 228-2222 or customerservice@hsainsurance.com

Electronic Check: 
It is free to pay by electronic check.  You will need one of your checks with you when you pay your bill online in order to get your account number and the bank’s routing number from it.  You will be shown where this information is on your check.

Important: Allow two (2) business days for your payment to be posted to your MBA/HSA account. Payments made after the due date will be subject to a late fee.  Please be advised that making an online payment does not guarantee immediate coverage. We reserve the right to decline an online payment if your account is in default for any reason.
