Most Medicare Part B enrollees never receive a separate premium bill: the premium is withheld from their Social Security or Railroad Retirement Board (RRB) benefit. If you do not receive either benefit, or the benefit is too small to cover the full premium, Medicare generally sends a CMS-500 Medicare Premium Bill. A Part B-only bill is usually issued every three months, and Medicare must receive your payment by the 25th of the month shown on the bill.
This guide explains what the bill covers, how much Part B costs in 2026, every payment method, processing times, and what to do when a payment is late or fails.

Who receives a Medicare Part B premium bill?
Your billing method depends mainly on whether a federal benefit is available from which Medicare can withhold the premium.
People whose premiums are withheld automatically
Most beneficiaries have their Part B premium deducted from a monthly Social Security or RRB benefit. The deduction is automatic, so these beneficiaries generally do not receive a separate CMS-500 for the same premium. The amount withheld reflects the premium Medicare has assigned to the beneficiary, including any income-related adjustment that applies.

People who pay Medicare directly
Medicare generally sends a bill when you are enrolled in Part B but do not receive Social Security or RRB benefit payments. You may also receive a bill if your benefit is not large enough to cover the full premium. In those situations, the CMS-500 tells you the amount due, the months covered, and the payment deadline.
RRB-specific billing
Some Railroad Retirement beneficiaries receive a bill directly from the Railroad Retirement Board rather than from Medicare. Follow the instructions on that RRB bill. Medicare’s general CMS-500 payment directions apply to bills sent by Medicare, not necessarily to an RRB-issued notice.
What the CMS-500 bill covers
A Part B-only bill is generally quarterly. It normally includes the next month and, when the bill is quarterly, the following future months as well. The monthly premium and the total amount due are therefore different figures: direct payers may owe several months at once even though Part B is priced monthly.

Medicare bills usually arrive around the 10th of the month. Read the bill itself for the controlling amount, months covered, and exact due date. A first bill, a missed payment, or a premium change can cause the CMS-500 to include past months in addition to upcoming months. That can make the total substantially higher than one month’s premium without indicating a penalty by itself.
How to read the important lines
- Amount due: The total Medicare expects for the billing period, which can cover one month, a quarter, or past and future months together.
- Months covered: The specific months for which the payment applies. Confirm these before paying, particularly after a change in coverage or premium.
- Due date: Medicare must receive the payment by this date, not merely have it mailed or scheduled by then.
- Past-due amount: Any unpaid balance carried forward from an earlier bill.
How much is Part B in 2026?
The standard Medicare Part B premium for 2026 is $202.90 per month, according to the Centers for Medicare & Medicaid Services. This is a standard administrative rate, not a guarantee of what every beneficiary owes. Some people pay more because of an income-related adjustment, and a direct payer’s quarterly bill will show multiple monthly premiums together.

Use your own CMS-500 to determine the amount you must pay. Do not multiply $202.90 by the number of months and assume that is the bill total; your notice may include a different premium, past months, or another adjustment.
Every way to pay a Medicare Part B bill
Medicare offers several payment routes. The best choice depends on whether you need a one-time payment, automatic recurring deductions, or a method that does not require online access.
| Method | How it works | Convenience and adjustment | Important caution |
|---|---|---|---|
| Medicare account, one-time payment | Sign in to your secure Medicare account and pay with a credit card, debit card, HSA card, or checking or savings account. | Medicare describes this as the fastest option. You choose the amount each time. | Check the bill before every payment. Bank-account payments generally take about five business days. |
| Medicare Easy Pay | Authorize a free recurring electronic debit from a bank account. | The deduction amount updates when your premium changes, so you do not need to recalculate each month. | Initial setup can take six to eight weeks. Use another payment method until deductions actually begin. |
| Bank bill pay | Set up a one-time or recurring payment through your bank’s bill-pay service. | Useful if you already manage bills through your bank. | Some banks charge a fee. The bank may mail a check, which requires extra delivery time. |
| Send a check or money order with the payment coupon from the CMS-500. | Does not require an online account. | It takes longer than electronic methods. A card payment by mail requires the coupon to be completed and signed. |
How to pay online through your Medicare account
For a one-time electronic payment, use the secure Medicare account payment feature rather than creating a separate Pay.gov account independently. The account lets you enter the amount shown on your bill and select an eligible payment source.
- Review the CMS-500 and identify the total amount due, months covered, and due date.
- Sign in to your secure Medicare account.
- Open the premium payment area and choose a one-time payment.
- Select a credit card, debit card, HSA card, or checking or savings account.
- Enter the amount due and verify the payment date and account details.
- Submit the payment and save the confirmation for your records.
A checking or savings payment generally takes about five business days to process. Initiate it at least five business days before the 25th, and earlier if the due date falls near a holiday or weekend.
How Medicare Easy Pay works
Medicare Easy Pay is a free recurring bank debit. After enrollment is active, Medicare generally deducts the premium on the 20th of the month or the next business day. When your premium changes, the recurring deduction updates automatically.
Allow time for enrollment
Easy Pay setup can take six to eight weeks. Continue paying by another method until you see that the automatic deductions have started. Stopping other payments immediately after submitting an Easy Pay request can leave a bill unpaid during the setup period.

If an Easy Pay payment fails, Medicare sends a letter and a bill. Pay the amount due using another method and check that the bank-account information is correct. Do not assume a failed debit will be retried in time to satisfy the bill’s deadline.
Using bank bill pay
Your bank may allow one-time or recurring payments to Medicare. Enter the payee information exactly as shown in your bill-pay system and use the account or identification details Medicare requests. Ask the bank whether it sends an electronic payment or mails a check. A mailed check needs additional time, and some banks charge for the service.
Schedule recurring bill pay only after confirming how the bank handles a changed premium. You remain responsible for ensuring that Medicare receives the correct amount, even if a bank’s recurring instruction continues using an old amount.
Paying by mail
Use the payment coupon attached to the CMS-500. Enclose the payment requested for the months listed on the bill and mail it according to the address and instructions printed on that notice. If you pay by card through the mail, complete and sign the coupon as required.

Mail takes longer than online payment. Send it well before the due date and retain a copy of the coupon, payment instrument, and mailing record. Medicare must receive the payment by the deadline, so the postmark alone does not establish timely receipt.
Deadlines and processing time
The CMS-500 is due on the 25th of the month shown. Medicare must receive the payment by that date. A practical rule is to submit any payment at least five business days early; mailed payments may need more time.
| Payment route | Timing information | Planning rule |
|---|---|---|
| Medicare account, checking or savings | Generally about five business days to process. | Submit at least five business days before the 25th. |
| Medicare account, card or HSA card | Medicare identifies the account payment option as the fastest, but the bill is not paid until the transaction is accepted. | Do not wait until the due date; confirm the online receipt. |
| Medicare Easy Pay | Usually debits on the 20th or next business day once active; setup takes six to eight weeks. | Use another method until the first automatic deduction appears. |
| Bank bill pay | Timing depends on whether the bank sends an electronic payment or a check. | Schedule early and ask the bank about delivery and fees. |
| Longer and less predictable than electronic processing. | Mail before the due date with the coupon and keep proof of payment. |
What happens if you miss or underpay?
A missed or late payment can appear as past due on your next bill. A delinquent notice warns that failure to pay the total by the stated deadline can lead to loss of Medicare coverage. Treat that warning as urgent: review the full balance, pay by an available method, and retain confirmation.
If your payment covered only one month when the bill required a quarter or included past months, the remaining balance can still show as past due. Compare your confirmation with the bill’s months-covered section before assuming Medicare applied the payment incorrectly.

The amount changed
A premium change can alter the amount due, and an income-related adjustment can make your premium higher than the standard 2026 rate. Use the current bill rather than an earlier amount. Easy Pay is designed to update its deduction when the premium changes; manual payments require you to review the new total.
You are waiting for Easy Pay to start
Continue making payments another way during the six- to-eight-week setup period. If a bill reaches its due date before the first debit, the bill remains your responsibility.
Your bank payment is still pending
Online checking or savings payments generally take about five business days. If the due date is close and the payment has not posted, check your account confirmation and consider contacting Medicare before submitting a duplicate payment. Keep all transaction details available.
You received an RRB bill
Use the instructions, payment address, and contact information on the RRB notice. Medicare’s general CMS-500 process is for bills sent by Medicare.
Keeping records and getting help
Save each bill, payment confirmation, bank record, and mailed-payment proof. These documents show the amount you intended to pay, the months covered, and when you submitted it.
For questions about a Medicare bill or payment, call 1-800-MEDICARE (1-800-633-4227). TTY users can call 1-877-486-2048. Have your Medicare number, the CMS-500, and any payment confirmation available so the representative can locate the correct billing period.
