Start with your local Social Security office or 1-800-772-1213
Your first call should be to Social Security directly. The phone line 1-800-772-1213 is open Monday through Friday, 7 a.m. to 7 p.m. Eastern time. A representative can answer questions about your Social Security benefits, when you can claim, how much you might receive, and how Medicare connects to your benefits. They can also schedule an in-person appointment at your local Social Security office if you prefer to talk face-to-face.
If you call during busy times, wait times can be long. Early morning or mid-week calls tend to move faster. You can also create an account at ssa.gov and message Social Security through your online account — responses usually come within three to five business days, which is slower than a phone call but lets you avoid hold times.
Key Takeaways
- Social Security handles both your benefits and the Medicare enrollment important date tied to claiming, so they are your first stop for questions about timing and amounts.
- Medicare.gov has a phone line (1-800-MEDICARE) separate from Social Security, and it answers questions about coverage, plans, and what Medicare will and will not pay for.
- Your State Health Insurance information Program (SHIP) offers free, one-on-one help comparing Medicare plans and understanding your coverage — find yours at shiptalk.org.
- Your doctor's office, hospital billing department, or insurance company can clarify whether a specific service or medication is covered under your plan.
- If you disagree with a Medicare decision or Social Security benefit amount, you have the right to appeal — ask the agency that made the decision how to file.
Call Medicare directly for coverage and plan questions
Medicare.gov runs a separate phone line: 1-800-MEDICARE (1-800-633-4227). This line answers questions about what Medicare covers, which plans are available in your area, how much you will pay out of pocket, and whether a specific doctor or hospital is in your plan's network. They can also help if you are confused about the difference between Original Medicare and Medicare Advantage, or between Part A, Part B, Part D, and Medigap.
The Medicare line is open 24 hours a day, seven days a week. Calls are usually shorter than Social Security calls because the questions are more straightforward. If you are calling during Medicare's annual open enrollment period (October 15 through December 7 each year), expect longer waits — that is when millions of people are comparing plans.
Get free one-on-one help from your State Health Insurance information Program
Every state runs a State Health Insurance information Program (SHIP) that offers free counseling about Medicare. A SHIP counselor can sit down with you (in person or by phone) and walk through your specific situation: which plan might cost you less, whether you may have access to for programs that help pay premiums, and what to do if you disagree with a coverage decision. They work for your state, not for Medicare or any insurance company, so they have no reason to steer you toward one plan over another.
Find your state's SHIP at shiptalk.org, or call 1-877-839-2675 and they will connect you to the right office. Many SHIPs also offer group workshops in your community — these are especially helpful if you are newly may be able to access for Medicare and want to understand the basics before making choices.
Talk to your doctor about what your plan covers
Your doctor's office knows which insurance plans they accept and can tell you whether you will need a referral to see a specialist, whether a test or procedure requires pre-approval, and whether a medication is on your plan's formulary (the list of drugs the plan will pay for). Call your doctor's billing department with your Medicare plan name and member ID number — they can answer most coverage questions in minutes.
If your doctor prescribes a medication and your pharmacy says it is not covered, ask the pharmacy to contact your doctor's office. Sometimes the doctor can request a prior authorization or suggest a different medication that your plan does cover. Do not skip the medication while this is being sorted out — tell your doctor and pharmacist what is happening so they can help you find a solution quickly.
Contact your insurance company if you have a Medigap or Medicare Advantage plan
If you have chosen a Medicare Advantage plan or a Medigap policy, your insurance company's customer service number is on your insurance card. Call them with questions about your specific coverage, your out-of-pocket costs, which doctors are in your network, and how to file a claim. They can also tell you whether you need a referral to see a specialist or pre-approval for a procedure.
Keep your insurance card with you and have it ready when you call. Customer service representatives can pull up your account and answer questions much faster when they have your member ID number in front of them.
Appeal a decision you disagree with
If Medicare denies a claim, Social Security calculates your benefit amount in a way you think is wrong, or your insurance company refuses to cover something you believe should be covered, you have the right to appeal. The process is different depending on which agency or company made the decision.
For Medicare coverage decisions, call 1-800-MEDICARE and ask how to file an appeal. For Social Security benefit decisions, contact your local Social Security office or call 1-800-772-1213 and ask about the appeals process. For insurance company decisions, look at your denial letter — it will explain how to appeal and the important date for filing. You do not need a lawyer to appeal, though you can hire one if you choose.
Find help in your community
Many senior centers, libraries, and Area Agencies on Aging offer free help understanding Medicare and Social Security. Call your local Area Agency on Aging to ask whether they have counselors available, or search for yours at eldercare.acl.gov. Some communities also have volunteer tax preparation sites (like VITA programs) that help seniors understand their benefits and how they affect their taxes.
If you are having trouble affording Medicare premiums or out-of-pocket costs, ask your Social Security office or SHIP counselor about Medicare Savings Programs and Extra Help — these are programs that help people with lower incomes pay for Medicare costs. You may may have access to even if you do not think you do.
Frequently Asked Questions
What should I have ready before I call?
Have your Social Security number, Medicare number (on your red, white, and blue Medicare card), and any insurance policy numbers ready. If you are calling about a specific claim or benefit decision, have that letter or document in front of you. Knowing your date of birth and current address also speeds things up.
Can I get help if I do not speak English well?
Yes. Both Social Security (1-800-772-1213) and Medicare (1-800-MEDICARE) offer free interpretation services in dozens of languages. Tell the representative your language when you call, and they will connect you to an interpreter at no cost to you.
What if I disagree with what a representative told me?
Ask the representative for their name and the date and time of your call, then call back and speak to someone else. You can also request a written explanation of the decision. If you still disagree, ask about the appeals process — every agency and insurance company has one.
Is there a charge for calling these numbers?
No. Calls to Social Security (1-800-772-1213), Medicare (1-800-MEDICARE), and your state's SHIP are free. Your insurance company's customer service line is also free — the number is on your insurance card.
When should I call — before I turn 65 or after?
Call Social Security about three months before you turn 65, even if you do not plan to claim benefits right away. They can explain how waiting affects your benefit amount and how Medicare enrollment important date work. If you miss a important date, calling right away to ask about your options is important — some missed important date carry penalties that last for years.
