Medicare Premium Bills: How Seniors Avoid Losing Coverage
Last updated: April 8, 2026
Bottom Line: If Medicare sends a paper premium bill instead of taking the money from Social Security, that bill has real deadlines. Medicare says premium bills are due on the 25th of the month, and a bill marked “Delinquent Bill” can lead to coverage termination if the full amount due is not paid by the deadline. Medicare Easy Pay, online payment through a secure Medicare account, and fast action on warning notices can prevent most avoidable coverage loss.
Emergency help now
- Read the top of the bill first: If it says “Delinquent Bill” or shows a coverage termination date, treat it as urgent. Medicare says a Delinquent Bill can lead to loss of coverage if the full amount due is not paid by the due date.
- Pay the full amount due using the fastest safe method you can: payment through a secure Medicare account is the fastest option. If that is not possible, send payment right away by bank bill pay or mail with the coupon from the bill.
- Call for help the same day if the amount looks wrong or coverage already ended: call 1-800-MEDICARE (1-800-633-4227) for billing questions, and call Social Security at 1-800-772-1213 or use the local Social Security office locator if the bill says coverage was canceled or is about to be canceled.
Quick help
- CMS-500 is the official Medicare premium bill for people who pay Medicare directly.
- Most direct-billed Part B accounts are billed every 3 months, while premium Part A and Part D Income-Related Monthly Adjustment Amount (IRMAA) are billed monthly.
- Bills usually arrive around the 10th and are due by the 25th of that month.
- Easy Pay is free, but it can take 6 to 8 weeks to start, and deductions usually happen on the 20th of the month or the next business day.
- Your Part D plan premium is not the same as Part D IRMAA. CMS-500 can include Part D IRMAA, but your drug plan bills its own premium separately.
- If a bill says “THIS IS NOT A BILL,” that usually means Medicare Easy Pay has been set up and automatic deductions should begin.
What this really means for seniors
Open every Medicare envelope right away. Direct-billed Medicare is easy to miss because there is no automatic deduction to remind a person that a premium is due. One missed paper bill can turn into a past-due bill, then a Delinquent Bill, then a termination notice.
Know the difference between “I have Medicare” and “my premiums are being handled.” Many older adults assume Medicare will work like Social Security withholding, but Medicare only deducts premiums automatically if a person is getting Social Security or Railroad Retirement Board benefits. If those benefits have not started yet, or if the person owes certain other Medicare amounts, Medicare expects a direct payment.
Do not wait for a second notice. Medicare’s direct-billing system is notice-driven. That means the safest move is to act on the first bill, not the last warning. It also means caregivers need a paper trail: the bill, the payment method, the confirmation number, and notes from any phone calls.
If the real problem is affordability, ask for cost help before coverage is lost. Medicaid and Medicare Savings Programs can pay some Medicare premiums for eligible low-income people. Waiting until coverage has already terminated can make the fix much harder.
Quick facts
- Most people never get a CMS-500 bill: Part B is usually deducted from Social Security or Railroad Retirement benefits.
- Direct-billed frequency: Part B only is usually billed every 3 months, premium Part A monthly, and Part D IRMAA monthly.
- 2026 premium amounts vary: the standard Part B premium is $202.90 in 2026, and premium Part A is $311 or $565 per month depending on work history. Bills can be higher if a late-enrollment penalty or Income-Related Monthly Adjustment Amount applies.
- First bills can be higher than expected: a CMS-500 can include past months, a missed payment, or a premium change.
- Award notices are not bills: Social Security policy says the award notice is not the bill, and the first CMS-500 should usually arrive within 30 days after the award notice.
Who this is for
- Older adults with Original Medicare who pay Part A or Part B premiums directly
- People whose Social Security retirement benefits have not started yet
- People who owe Part D IRMAA and are confused about what Medicare bills directly versus what a plan bills separately
- Caregivers, spouses, and adult children helping a parent avoid missed Medicare bills
- Federal retirees who may want to ask whether Part B premiums can be withheld from an Office of Personnel Management annuity
Know which paper you got before paying anything
| Document | Who sends it | What it means | What to do first |
|---|---|---|---|
| CMS-500 Medicare Premium Bill | Medicare | The official bill for people who pay Medicare directly for Part A, Part B, and/or Part D IRMAA | Read the Bill Type, Total Amount Due, and Due In Full By lines first. |
| CMS-20143 Medicare Easy Pay Premium Statement | Medicare | A monthly statement showing what Medicare will automatically deduct from a bank account | Make sure the amount looks right and the bank account has enough money. |
| Plan premium bill | Your Medicare Advantage or Part D plan | The plan’s own premium bill. This is separate from CMS-500. CMS guidance says plans must give at least two whole calendar months of grace period before disenrollment for nonpayment. | Pay the plan bill or call the plan right away. Do not assume Medicare’s CMS-500 covers it. |
| Social Security or Medicare award notice | Social Security or Medicare | Important coverage or premium information, but not the actual bill | Wait for the CMS-500, or check your Medicare account if you are comfortable online. |
| Medigap premium bill | Private Medigap insurer | A separate private insurance bill that is not part of CMS-500 | Pay the insurer separately. Keep Part B active, because you must have Part B to keep Medigap. |
Why some seniors get billed directly instead of having premiums deducted
Assume Medicare expects direct payment if there is no benefit check to deduct from. The most common reason for a CMS-500 bill is simple: the person is not receiving Social Security benefits yet. Medicare then sends a direct bill instead of taking the premium out of a monthly retirement payment.
Know which premium creates which bill. According to Medicare’s premium payment page, people billed directly may receive:
- Part B only: usually every 3 months
- Premium Part A: monthly
- Part D IRMAA: monthly
Do not confuse Part D IRMAA with the actual Part D plan premium. Medicare explains that CMS-500 may include Part D IRMAA, but the actual Part D plan premium is billed by the drug plan.
If the bill seems larger than expected, check the coverage dates before assuming it is wrong. Medicare says the bill can include past months if it is the first bill, if a payment was missed, or if the premium changed. The bill may also include a late-enrollment penalty or an income-related charge.
Federal retirees have one extra option in some cases. If a person is not receiving Social Security but does receive a federal annuity, the Office of Personnel Management says Part B premiums may be withheld from the annuity after the request is started through Social Security. That can reduce the risk of future paper-bill problems.
How to do this without wasting time
Pick one reliable payment method and stick with it. Switching back and forth between paper checks, bank bill pay, and unfinished Easy Pay setup is one of the easiest ways to create confusion.
| Payment method | Best for | How it works | Main warning |
|---|---|---|---|
| Secure Medicare account | Fast one-time payments | Pay online by credit card, debit card, Health Savings Account card, or checking/savings account. Checking or savings payments usually take about 5 business days. Card payments process faster. | Use only the Medicare account path. Medicare says not to create or use a separate Pay.gov account for Medicare premium payments. |
| Medicare Easy Pay | Recurring payments from a bank account | Free automatic monthly deduction from checking or savings. Sign up online or by mailing the SF-5510 Easy Pay form. | It can take 6 to 8 weeks to start, so it is not a same-day fix for a delinquent bill. |
| Bank bill pay | People who already pay household bills through a bank | Use the payee name CMS Medicare Insurance, the Medicare Premium Collection Center, PO Box 790355, St. Louis, MO 63179-0355, and the person’s Medicare number without dashes as the account number, based on Medicare & You. | Some banks charge fees, and the first payment should be scheduled early enough to arrive before the due date. |
| Paper-based households | Mail the coupon and payment to the Medicare Premium Collection Center. Medicare accepts check, money order, and mail-in card payments using the coupon. | Do not send letters with the payment, do not write notes on the coupon, send only one payment and one coupon per envelope, and sign the coupon for card payments. |
If mailing, always include the coupon. Medicare warns that payments can be delayed if the coupon is not included. If the coupon is missing, write the Medicare number on the check or money order.
How Medicare Easy Pay really works
Use Easy Pay to prevent future missed bills, not to solve today’s delinquent bill. Medicare Easy Pay is a free recurring-payment option, but it can take 6 to 8 weeks before deductions begin. Until then, Medicare expects the premium to be paid another way.
Watch the timeline closely. After Easy Pay starts, the Medicare Easy Pay statement usually arrives on or about the 10th of the month, and the deduction usually happens on the 20th or the next business day.
Expect the first withdrawal to be larger than one month in some cases. CMS says the first Easy Pay deduction can be up to 3 months of premiums. After that, the usual limit is one month’s premium plus $10. This is important for older adults on a tight fixed income, because a small checking account cushion may not be enough.
Look for the “THIS IS NOT A BILL” message. CMS says successful Easy Pay setup will change the CMS-500 to show “THIS IS NOT A BILL” in the upper right corner. That is a strong sign that automatic deductions should begin.
If the bank rejects the deduction, do not assume it will fix itself next month. Medicare says it will send a letter explaining why, then send a bill the next month. Once the full amount due is paid another way, Easy Pay can start back up again.
What happens after one missed payment
Pay the first missed bill as soon as you notice it. Waiting for the next statement only makes the balance harder to fix.
| Stage | Usual timing for a quarterly-billed Part B account | What it means in real life | Best action now |
|---|---|---|---|
| Initial CMS-500 bill | Usually arrives around the 10th of the month | The bill covers upcoming coverage and may cover 3 months if it is Part B only. | Pay by the 25th of the month. |
| Past-due amount appears | After a missed or late payment | The next bill includes the past-due amount. | Pay everything due, not just the current month. |
| Second Notice | About 60 days after the initial quarterly bill | This is a formal reminder that the premium is still overdue. | Do not wait for another notice. Pay now. |
| Delinquent Bill | About 90 days after the initial quarterly bill | Coverage termination date appears when the account is 90 days past due. | Pay the full Total Amount Due by the Due In Full By date. |
| Termination notice | Generally mailed about 30 days after the grace period ends | Coverage may already be shown as terminated in the record if no payment has posted. | Call Medicare and Social Security the same day. Keep proof of payment. |
Important: Social Security policy says a partial payment may still lead to termination if the past-due balance remains more than $10. A small catch-up payment may not be enough.
Also important: a payment mailed on or before the last day of the grace period is considered timely, and if a payment is processed during the due-process period, the termination date can be removed. That is why dated proof matters.
How to fix a late or missed payment before coverage is lost
Start by paying the full delinquent total, not the current month only. That single step solves many cases that turn into avoidable termination.
- Read the three lines that matter most. Look for Bill Type, Total Amount Due, and Due In Full By. On a Delinquent Bill, the coverage termination date and full amount due are printed clearly on the bill.
- Pay the full amount due using the fastest method you can use correctly. Online payment through a secure Medicare account is fastest. If mailing, include the coupon and send it right away.
- Keep proof. Save the online confirmation number, bank screenshot, copy of the front of the check, or money-order receipt. If mailing, keep a copy of the coupon and the envelope date if possible.
- Call 1-800-MEDICARE after paying. Ask whether the payment is posted or pending and ask the representative to note the account. Use Medicare’s official contact information.
- If the missed payment happened because of circumstances outside the person’s control, contact Social Security immediately. Social Security policy allows an additional 90-day extension of the grace period, for a total of up to 180 days, when good cause exists and all overdue premiums are paid by the end of the extended period.
Good-cause examples matter. Social Security says good cause can exist when the person was mentally or physically unable to pay on time and no one was protecting their interests, reasonably believed the payment had been made, or did not receive the bill because of administrative error such as a misaddressed notice. The same policy also says poverty alone is not good cause.
Document checklist
- ☐ The current CMS-500 bill, especially if it says Delinquent Bill
- ☐ The person’s red, white, and blue Medicare card
- ☐ Proof of payment: confirmation number, canceled check image, bank statement, or money-order receipt
- ☐ Any Easy Pay letters or the SF-5510 form if Easy Pay was requested
- ☐ Any bank rejection notice or returned-payment letter
- ☐ Any Social Security notice about premium changes or income-related charges
- ☐ A written call log with dates, names, and reference numbers from Medicare or Social Security
- ☐ If a helper will speak to Medicare, the older adult’s permission through Medicare’s Authorization to Disclose Personal Health Information process
Reality checks
- A Delinquent Bill is not a routine reminder. It means coverage is in danger.
- Easy Pay is not instant. It usually takes 6 to 8 weeks to begin.
- Partial payments can fail. A small payment may not stop termination if the old balance is still too high.
- You may have more than one Medicare-related premium bill. CMS-500, a plan premium bill, and a Medigap bill are not the same thing.
Common mistakes to avoid
- Paying only the current month when the bill says the full delinquent amount is due
- Assuming Easy Pay has started before the bill changes to “THIS IS NOT A BILL”
- Using the wrong bill to decide what is owed, especially confusing CMS-500 with a plan premium bill
- Mailing payment without the coupon or forgetting to sign the coupon for a card payment
- Sending notes or extra letters in the payment envelope, which Medicare says can delay payment
- Ignoring an address problem after a move instead of updating Social Security
- Assuming a caregiver can call and get account details without permission
- Waiting for another notice when a bill already says Delinquent
Best options by need
| If this is the problem | Best next move | Why it usually works best |
|---|---|---|
| Forgetting monthly or quarterly bills | Set up Medicare Easy Pay | It reduces paper-bill risk, but still requires checking the monthly statement and bank balance. |
| A delinquent bill that must be fixed today | Make a one-time payment through the secure Medicare account | It is the fastest official payment method. |
| No computer or no comfort with online accounts | Use bank bill pay or mail with the coupon | It keeps the process paper-based and familiar. |
| A caregiver is helping a parent | Set reminders, keep one paper folder, and use Medicare’s authorization-to-disclose process | That reduces missed mail and makes phone calls more productive. |
| The bill is too high to afford | Check Medicaid and Medicare Savings Programs, and get free counseling from SHIP | These programs can pay premiums for eligible low-income people. |
| A federal retiree wants automatic withholding | Ask about withholding from the annuity through OPM and Social Security | That can remove the direct-bill problem for some Part B cases. |
Troubleshooting: denial, delay, wrong billing, wrong notice, or missing paperwork
The bill looks wrong or much higher than expected
Compare the dates on the bill before arguing with the amount. Medicare says a CMS-500 can include past months, a first billing period, a missed payment, or a premium change. It can also include late-enrollment penalty amounts and IRMAA amounts. If the problem seems tied to Income-Related Monthly Adjustment Amount, call Social Security because Social Security determines IRMAA.
I paid, but Medicare still says I owe money
Use proof, not memory. Pull the confirmation number, bank image, or money-order receipt and call 1-800-MEDICARE. Social Security policy says a payment mailed on or before the last day of the grace period is timely, and the termination date can be removed if payment is processed during the due-process period.
I never got the bill, or the bill went to the wrong address
Update the address right away through Social Security. Medicare & You says address changes on the bill go through Social Security. After a move, do not assume the Post Office will fix everything. If needed, ask for large print, Braille, audio, or other accessible formats.
Easy Pay failed, or the bank account changed
Pay the current bill another way first. Medicare says bank-account changes can take 6 to 8 weeks, and rejected deductions trigger a letter and then a new bill. If Easy Pay needs to be updated by mail, use the SF-5510 form instructions.
Coverage already terminated for nonpayment
Call Social Security the same day. The sample CMS-500 says people whose Medicare coverage is canceled should contact the local Social Security field office or call 1-800-772-1213. If the nonpayment happened because of illness, administrative error, or another situation outside the person’s control, ask about good-cause relief and reinstatement rules. Be ready to show proof and to pay overdue premiums.
If reinstatement is not available, ask when reenrollment can happen. The General Enrollment Period runs from January 1 through March 31 each year, and coverage starts the month after sign-up. A late-enrollment penalty may apply for Part B and, in some cases, for premium Part A.
Check other coverage right away after a Part B loss. Medicare says you must have Part B and keep paying the Part B premium to keep a Medigap policy. That means a Part B termination can create a second insurance problem fast.
This is a Medicare Advantage or drug plan premium, not a CMS-500
Do not apply CMS-500 rules to a plan bill. CMS requires Medicare Advantage and Part D plans to give at least two whole calendar months of grace period before disenrollment for nonpayment. If a plan says a premium was not paid, keep proof of any Social Security premium withholding or other payment arrangement. The same CMS guidance says plans may not disenroll people for nonpayment when the person is still in valid premium-withhold status.
How caregivers can safely help manage premium payments
Start with permission and a simple system. Social Security policy says a friend or relative may make Medicare premium payments on a beneficiary’s behalf. That makes caregiver help lawful and practical, but it does not solve communication problems by itself.
- Have the older adult authorize Medicare communication: use Medicare’s Authorization to Disclose Personal Health Information process so 1-800-MEDICARE can speak with the helper.
- Create one paper folder: keep every CMS-500, every payment confirmation, and every bank notice in one place.
- Use two reminder dates every month: around the 10th to watch for the bill or Easy Pay statement, and before the 20th or 25th to make sure the money is actually available or paid.
- Review every “high” bill line by line: older adults often panic over a three-month Part B bill or an IRMAA line that is not the same as a plan premium.
- Do not let more than one person mail payments without a log: duplicate or mismatched payments create new problems.

FAQ
What is a CMS-500 Medicare premium bill?
It is the official Medicare bill for people who pay Medicare directly. Medicare says CMS-500 is used for direct payment of Part A, Part B, and/or Part D IRMAA.
Why does a senior get a Medicare bill instead of having the premium deducted?
The most common reason is that Social Security benefits have not started yet. Social Security explains that if a person is not receiving monthly benefits, CMS mails a premium bill with payment instructions.
Does Medicare Easy Pay start right away?
No. Medicare says Easy Pay can take 6 to 8 weeks to start, so premiums still must be paid another way until the bank deductions begin.
If the bill says “Delinquent Bill,” can the person pay only the current month?
No, not safely. A Delinquent Bill means the past-due balance matters. Medicare says the full amount due must be paid by the due date to avoid losing coverage.
Is the Medicare drug plan premium on the CMS-500?
Can a caregiver pay the bill for a parent?
Yes. Social Security policy says a friend or relative may make the premium payment on the beneficiary’s behalf. It is still smart to set up Medicare disclosure permission so the helper can also discuss the account.
What if coverage already ended because of nonpayment?
Call Social Security right away. Ask about any reinstatement or good-cause option, and be ready to pay overdue amounts. If reinstatement is not available, the person may need to reenroll during the General Enrollment Period.
Can a senior still use paper-based payment methods?
Yes. Medicare still allows payment by mail and through bank bill pay. For many households, that is easier than managing another online login.
Resumen en español
Revise la factura el mismo día que llegue. La factura CMS-500 es la factura oficial de Medicare para personas que pagan sus primas directamente. Medicare indica que estas facturas normalmente vencen el día 25 del mes.
Si la factura dice “Delinquent Bill,” actúe de inmediato. Eso significa que la cobertura está en riesgo si no se paga el monto total adeudado antes de la fecha límite. La forma más rápida de pagar suele ser por medio de una cuenta segura de Medicare, pero también se puede pagar por correo o con el servicio de pago de facturas del banco.
Si ya hubo cancelación o la factura parece incorrecta, llame el mismo día. Comuníquese con 1-800-MEDICARE para preguntas de facturación y con el Seguro Social al 1-800-772-1213 si la cobertura terminó o está por terminar. Si el problema ocurrió por enfermedad, error administrativo u otra causa fuera del control de la persona, podría existir alivio por “good cause.”
