Premium Payments for Individual and Family Plans

​Quartz offers a variety of ways to pay your premium invoice. Choose the one that works best for you. 

Pay by Mail

If you prefer to mail your payment, detach the payment stub from your billing statement. Put it in the return envelope provided with your Premium Invoice, along with a check made out to Unity Health Plans Insurance Corporation. This option is available for all Unity Health Insurance Plans.


If you are mailing a payment without a stub, please write your account or policy number in the memo line of your check. Mail the check to –
