Bottom Line: A Medicare premium bill is not junk mail. If Medicare sends you a CMS-500 bill, it means Medicare expects direct payment. Most bills are due by the 25th of the month, and a bill marked Delinquent Bill can put coverage at risk if the full amount due is not paid by the deadline. The safest steps are to read the bill, pay the full amount due, keep proof, and call Medicare or Social Security right away if the amount looks wrong.
Emergency help now
- If the bill says Delinquent Bill: read the Total Amount Due and Due In Full By lines first. The sample CMS-500 bill explains that coverage can end if the full balance is not paid by that date.
- If you can pay today: use your secure Medicare account if you can use it safely. Medicare says this is the fastest payment path, and card payments process faster than checking or savings payments.
- If coverage already ended: call Social Security at 1-800-772-1213 and ask what reinstatement or good-cause option may apply. You can also use the SSA office locator to find a local office before you go in person.
- If the bill is too high: do not ignore it. Pay what you can only after asking what amount is required to stop termination. Then ask about Medicare Savings Programs, Medicaid, and SHIP counseling.
Quick help
- CMS-500: the official Medicare premium bill for people who pay Medicare directly.
- Part B billing: if Part B is billed directly, Medicare usually sends a bill every 3 months.
- Premium Part A and Part D IRMAA: these are usually billed monthly when direct-billed.
- 2026 standard Part B premium: $202.90 per month. It can be higher for people with higher income or late-enrollment penalties.
- Easy Pay: free automatic bank withdrawal, but it can take 6 to 8 weeks to start.
- Plan premium bills: a Medicare Advantage, Part D, or Medigap bill is not the same as a CMS-500 bill.
Quick-reference table
| If you received this | What it usually means | Best first move |
|---|---|---|
| CMS-500 Medicare Premium Bill | Medicare is billing you directly for Part A, Part B, Part B IRMAA, or Part D IRMAA. | Read the bill type, total due, and due date before paying. |
| Delinquent Bill | Your account is past due and coverage may be at risk. | Pay the full total due or call the same day if you cannot. |
| Medicare Easy Pay statement | Medicare plans to pull the premium from your bank account. | Make sure the amount and account balance are right. |
| Plan premium bill | Your Medicare Advantage, Part D, or Medigap company is billing you. | Call the plan. Do not assume Medicare’s CMS-500 covers it. |
| Social Security notice | It may explain premiums, IRMAA, benefits, or withholding. | Keep it, but wait for the bill or check your Medicare account. |

Know which bill you got
Start with the name of the paper. The Medicare premium bill page says CMS-500 is for people who pay Medicare directly for Part A, Part B, and/or Part D Income-Related Monthly Adjustment Amount (IRMAA). It is not the same as a private plan bill.
Read the top and the coupon. Look for Bill Type, Total Amount Due, Due In Full By, and any Coverage Termination Date. If you are helping a parent, take a photo or make a copy before the bill leaves the house.
Do not mix up Part D IRMAA and a Part D plan premium. Part D IRMAA is an extra income-based amount paid to the government. Your drug plan may still send its own premium bill. Paying one does not always pay the other.
Medigap is separate too. A Medigap company bills its own premium. Medicare says you must have Part B and keep paying the Part B premium to keep a Medigap policy. So a missed Part B bill can also create problems with a supplement policy.
Why seniors are billed
The most common reason is simple. If you are not getting Social Security or Railroad Retirement Board benefits yet, Medicare may not have a monthly benefit check to deduct from. The Social Security FAQ says CMS will mail a premium bill when the premium is not being taken from monthly Social Security benefits.
Federal retirees can be confused by this. Some people have a civil service or federal retirement payment instead of Social Security. If that is your situation, ask Social Security and your retirement system whether withholding can be set up. Until you have written proof that withholding has started, keep paying the CMS-500 bill.
Higher-income charges can create separate bills. Social Security decides whether a person owes IRMAA based on tax information. The higher-income premiums page explains that Part B and Part D IRMAA may apply when income is above the yearly limits.
First bills can look wrong. A first bill may include more than one month, a missed month, a premium change, IRMAA, or a late-enrollment penalty. Compare the coverage dates before assuming the amount is an error.
Pay without wasting time
Pick one payment method and keep proof. Switching between mail, bank bill pay, and unfinished Easy Pay setup can lead to missed payments. Use the method you can use correctly every time.
| Payment method | Best for | How it works | Reality check |
|---|---|---|---|
| Medicare account | Fast one-time payment | Log in, choose “Pay my premium,” and pay by card, HSA card, checking, or savings. | Use Medicare’s path only. Do not create a separate Pay.gov account. |
| Medicare Easy Pay | Future automatic payments | Medicare pulls the premium from checking or savings each month. | It is not a same-day fix because setup can take 6 to 8 weeks. |
| Bank bill pay | People who use their bank for bills | Set up CMS Medicare Insurance as the payee and use your Medicare number as the account number. | Schedule early. Bank processing time can cause late posting. |
| Paper-based households | Mail the coupon and payment to the Medicare Premium Collection Center. | Do not send cash. Include the coupon and do not write notes on it. |
If mailing, be exact. Make the payment payable to CMS Medicare Insurance. Write the Medicare number on the check or money order. Send one payment and one coupon in the envelope. Keep a copy of the coupon and proof of mailing if the bill is late.
If you use a card by mail, sign the coupon. Medicare says unsigned card coupons may be returned. That can cost time when a deadline is close.
How Medicare Easy Pay works
Use Easy Pay to prevent the next problem. Medicare Easy Pay is free and can pull monthly premiums from a checking or savings account. It can help seniors who forget paper bills.
Do not assume it has started. Medicare says Easy Pay may take 6 to 8 weeks to begin. Until then, pay the bill another way. If a bill still asks for payment, treat it as real unless Medicare confirms otherwise.
Watch for the monthly statement. Once Easy Pay starts, Medicare sends a statement and usually deducts the premium on the 20th of the month or the next business day. Keep enough money in the account before that date.
If the bank rejects payment, act fast. Medicare says it will send a letter and then a bill the next month. Pay the full amount due another way before counting on Easy Pay again.
Use the form only if needed. Seniors who prefer paper can use the SF-5510 form for Easy Pay, but online setup may be easier for someone who already has a secure Medicare account.
Missed payment timeline
One missed bill can grow quickly. A person may miss a quarterly Part B bill, then receive a bill with past-due charges, then receive a delinquent notice. Do not wait for another warning if you already see a past-due amount.
| Stage | What it means | Best action |
|---|---|---|
| Initial bill | Medicare is asking for payment for the listed coverage period. | Pay by the due date and keep proof. |
| Past-due amount | A prior payment may be missing or late. | Pay the full amount due, not just the new premium. |
| Delinquent Bill | The account is seriously late and coverage may terminate. | Use the fastest safe payment method and call Medicare. |
| Termination notice | Coverage may already show as ended or close to ending. | Call Social Security the same day and ask about reinstatement. |
Partial payments can fail. If the bill says the full balance is due, paying only the current month may not stop termination. Ask Medicare what exact amount must post by the deadline.
Good cause may help in some cases. Social Security policy allows an extra 90-day extension of the grace period, up to 180 days total, when there is good cause and overdue premiums are paid. The good-cause rule is narrow, so ask directly and keep records.
Poverty alone may not be enough. Social Security policy says low income by itself is not usually a reason to excuse a missed premium. If the real problem is affordability, apply for cost help before the account becomes delinquent.
Premium too high
Ask for cost help before coverage is lost. Medicare Savings Programs can help pay Part A and Part B premiums for people who meet state rules. Some programs may also help with deductibles, coinsurance, and copays.
Check both Medicare and drug help. Our Medicare Savings Programs guide explains the national QMB, SLMB, QI, and QDWI paths in plain English. The Medicare help checker can also help you decide what to ask about first.
| Need | Program to ask about | Where to start | Reality check |
|---|---|---|---|
| Part B premium is hard to afford | QMB, SLMB, or QI | State Medicaid office | Income and resource rules vary by state. |
| Prescription costs are too high | Extra Help | Social Security or Medicare | Drug plan costs may still vary. |
| Part D bills feel confusing | Plan help or SHIP counseling | Call the plan and SHIP | Part D IRMAA is separate from the plan premium. |
| Several bills are overdue | Local emergency help | Area agency, charity, or benefits office | Funds may be limited and not instant. |
Prescription help can lower pressure. Read our Extra Help guide if drug costs are part of the problem. Our prescription cost help guide may also help when plan copays or uncovered drugs are the issue.
Medicaid may help beyond premiums. Our Medicaid for seniors guide explains how Medicaid can help some older adults with health costs, long-term care, and Medicare-related costs.
Caregiver help and paper systems
A helper can pay, but permission still matters. A friend, spouse, adult child, or other helper may help pay a bill. But Medicare may not discuss account details unless the older adult has given permission.
Set up one folder. Keep the current CMS-500, Easy Pay letters, bank notices, proof of payment, Social Security letters, and call notes in one place. If two relatives are helping, use one payment log so nobody pays twice or assumes someone else paid.
Use two monthly reminder dates. Around the 10th, check for the bill or Easy Pay statement. Before the 20th or 25th, confirm that the bank account has enough money or that payment was sent.
Connect this to Social Security. If address, phone, direct deposit, or benefit status changes are part of the problem, our guide to manage Social Security can help families avoid missed mail and account confusion.
Phone scripts to use
For a Delinquent Bill: “I received a Medicare Premium Bill marked Delinquent Bill. The total amount due is ____. The due date is ____. What exact amount must be paid to keep coverage from ending, and which payment method will post fastest?”
For Easy Pay not starting: “I signed up for Medicare Easy Pay, but I still received a bill. Has Easy Pay started on my account? Should I pay this bill another way while I wait?”
For a wrong or high amount: “The bill is higher than expected. Can you explain each charge by coverage period, including Part B, Part A, IRMAA, penalties, or past-due amounts?”
For good cause or coverage ended: “Coverage may have ended because of nonpayment. The missed payment happened because ____. Can I request good-cause review or reinstatement? What proof do I need, and what amount must be paid?”
Document checklist

- Easy Pay approval, rejection, or bank-change letters
- Social Security letters about premiums, IRMAA, or benefit changes
- Plan premium bills from Medicare Advantage, Part D, or Medigap companies
- Call log with date, time, agency, person spoken to, and reference number
- Permission paperwork if a caregiver will speak for the older adult
Printable help: Our document checklist tool can help seniors and caregivers make one benefits folder before calling agencies.
Mistakes and reality checks
- Mistake: paying only one month when the bill asks for the full past-due total.
- Mistake: assuming Easy Pay has started before Medicare confirms it.
- Mistake: mailing a payment without the coupon or Medicare number.
- Mistake: confusing CMS-500 with a Part D plan, Medicare Advantage, or Medigap bill.
- Mistake: ignoring a Social Security address problem after moving.
- Reality check: banks, mail, and online payments can all take processing time.
- Reality check: phone representatives can explain the bill, but you still need written proof and payment records.
- Reality check: cost-help programs can take time, so apply before the bill becomes urgent.
Coverage ended or a plan dropped you
Call Social Security first for Original Medicare premium termination. If Part B or premium Part A ended because the CMS-500 was not paid, ask Social Security about reinstatement, good cause, and whether any payment can still fix the record.
Ask about enrollment dates if reinstatement is not available. Medicare says the General Enrollment Period runs from January 1 through March 31 each year, and coverage starts the month after a person signs up. A penalty may apply if no Special Enrollment Period is available.
Plan bills have different rules. A CMS document on the plan grace period says Medicare health and drug plans must give at least 2 calendar months before disenrolling someone for not paying a plan premium. Part D IRMAA is different and may lead to plan disenrollment after a 3-month grace period.
Open Enrollment may be the backup. Medicare Open Enrollment runs from October 15 through December 7 for many plan changes. This may not fix an immediate gap, so call SHIP if you are unsure what to do next.
If several bills are overdue: our emergency help guide may help you find local bill, food, housing, or utility help while you work on the Medicare problem. For drug plan payment issues, the Prescription Payment Plan may help spread some Part D out-of-pocket drug costs, but it does not pay a CMS-500 premium bill.

FAQ
What is a CMS-500 Medicare premium bill?
It is the official Medicare bill for people who pay Medicare directly for Part A, Part B, Part B IRMAA, or Part D IRMAA. Most people do not get this bill because their Part B premium is taken from Social Security or Railroad Retirement benefits.
Why did I get a Medicare bill instead of a Social Security deduction?
You may not be receiving Social Security benefits yet, or Medicare may be billing you for another amount that is not being withheld. Call Medicare or Social Security if you expected automatic deduction.
Does Medicare Easy Pay start right away?
No. It can take 6 to 8 weeks to start. Until Medicare confirms Easy Pay is active, pay any bill that asks for payment another way.
Can I pay only the current month on a Delinquent Bill?
Not safely. A Delinquent Bill may require the full total due by the listed deadline. Paying only part of the balance may not stop termination.
Is Part D IRMAA the same as my drug plan premium?
No. Part D IRMAA is an income-based amount paid to the government. Your Part D plan may bill its own premium separately.
Can a caregiver pay a parent’s Medicare premium bill?
Yes, a helper can pay. But Medicare may need permission before it will discuss the account with that helper.
What if Medicare coverage already ended for nonpayment?
Call Social Security right away. Ask about reinstatement, good cause, the amount due, and what proof is needed. If reinstatement is not possible, ask when reenrollment can happen.
Where can I get free help understanding the bill?
Call 1-800-MEDICARE for billing questions and contact SHIP for free local Medicare counseling. If the bill is tied to Social Security, call Social Security too.
