For Part C, Part D, and Medigap, you can pay with your Thatch Card. Most insurance companies let you set up autopay in their own member portal — find your card in the Cards section of your dashboard, and activate it before your first payment. Your health budget lands at the start of each month, so scheduling autopay for the first few days of the month is the safest timing.
Part B usually won't go through on a card. For Parts A and B, pay from your own account or via social security deductions, and request a reimbursement. You can also set up Medicare Easy Pay to utilize your Thatch card for these premiums.
