Welcome to ​Quartz

Thank you for choosing ​Quartz! We want to make it as easy as possible for you to use your health plan. To help you, we've created this member kit to walk you through important details.

Your monthly premium is due on the first of each month to the company underwriting your policy – Unity Health Plans Insurance Corporation. To avoid having your coverage termed or canceled and risk not having insurance until the next open enrollment period, be sure to pay the full premium amount on time each month. To avoid losing your insurance and having payment of a claim denied, make sure you pay the full premium payment before the end of your applicable grace period. If you apply for a new policy with Quartz, you may be required to pay any outstanding premiums you owe on this or other past due accounts before the new coverage can begin.

Grace Periods and Pending Claims

A grace period is the amount of time you have to pay your Premium Invoice. The duration is dependent on whether you get subsidies or not.

  • If the government helps you pay your premium – If you are getting advanced premium tax credits (APTC), by law, you have 90 days to bring your payments up to date. This is called a “grace period”. If you don’t pay any premiums at all after you enroll in the plan, your policy will be cancelled. If you enrolled and paid one premium, you have 90 days to pay all premiums owed. If not, your policy will be terminated. ​Quartz will pay claims during the first 30 days of the 90-day grace period. After that, Quartz will not pay claims, and you are responsible for those costs unless you catch up on your premium payments by the end of the grace period. If you terminate your policy after one month, or if your coverage is terminated due to failure to pay within the 90-day grace period, you are still responsible for paying the first month’s Premium Invoice.
  • You don’t get help paying your premium – You have 10 days to pay your Premium Invoice after the due date. Otherwise, Quartz will not pay claims and your policy will be terminated.

Retro-active denials

Claims may be denied retro-actively if your policy is cancelled for non-payment. You will be responsible for paying all claims incurred after the termination date of your policy. In order to avoid your claims being retro-actively denied for payment, make sure to pay your premium on time each month.

A variety of ways to pay your premium invoice are available. Choose the one that works best for you. ​
