How Medicare Premiums Affect SSDI Payments

Published:

If you get Social Security Disability Insurance (SSDI) or are applying for it, Medicare coverage can change your monthly payment.

This Medicare premiums SSDI guide explains when federal health insurance starts, which premiums are automatically deducted, and what to check if your deposit drops.

Medicare Premiums SSDI: Why Your Payment Drops 

When Medicare begins, the Medicare premium deduction for Part B is typically taken from your SSDI payment. Other parts of the insurance may be deducted from your payment by request.

If you get a Medicare bill instead of a deduction, it’s likely because your benefits don’t cover the Medicare payment.

When Medicare Starts

When you get SSDI, Medicare automatically starts 24 months after your entitlement date (except in a few cases). Your entitlement date is when you start getting benefits, not when you’re diagnosed. If you are unsure about your entitlement date, check your award notice.

Three months before Medicare starts, you will get a “Get Ready for Medicare” package. It includes a letter, booklet, and your Medicare card. Read this booklet to pick your insurance options before coverage starts. If you don’t get your packet, download one or call 1-800-633-4227) to request one (1-877-486-2048 for TTY users).

ALS and ESRD Exceptions

Medicare coverage starts earlier in cases of amyotrophic lateral sclerosis (ALS) and end-stage renal disease (ESRD). ALS cases have no waiting period. When coverage starts in ESRD cases depends on the treatment.

If you (or a family member) are having a kidney transplant or undergoing dialysis for ESRD, contact the SSA to enroll in Medicare. You will need both Part A and Part B to get the full benefits for dialysis or a kidney transplant.

Medicare Parts That Can Affect SSDI Payments 

Medicare has four parts: A, B, C, and D.

  • Part A is hospital coverage. It covers inpatient hospital and hospice care and some home health services. It may also pay for care in a nursing facility after a qualifying hospitalization.
  • Part B is medical insurance. It covers doctor visits, preventative care, outpatient treatment, and medical equipment. Part B also covers specialists, labs, x-rays, tests, and medical equipment.
  • Part C is an all-in-one alternative to original Medicare. Private insurance companies approved by Medicare offer Part C, called Medicare Advantage. Medicare Advantage bundles Part A, Part B, and usually Part D into one plan. Plans may offer extra coverage like dental, hearing, vision, and health and wellness programs.
  • Part D is prescription drug coverage. It’s also provided by private companies that are required to follow Medicare rules. This coverage is optional, but there’s a late enrollment penalty if you go 63 days without prescription insurance.
  • Medigap is optional coverage that helps pay copayments, coinsurance, and deductibles. It’s not available in every state for people younger than 65. You must be covered by Part A and Part B to get Medigap. 

Which Medicare Premiums Are Deducted from SSDI 

Part A 

You don’t pay for Medicare Part A when you get SSDI or when your spouse of at least one year gets SSDI. You also get Part A without charge if your ex-spouse gets SSDI and you were married for at least 10 years or if they got SSDI, you were married for nine months, and now you’re widowed.

Part B

When Medicare starts, the Part B premium is usually automatically deducted from SSDI. The premium changes almost every year, so your deduction changes too.

Part C

Since Part C is through private insurance companies, your Medicare Advantage premium can only be deducted if your specific plan allows it and you set it up with the company. 

Part D

Part D can be deducted from your SSDI payment by request or billed to you. You typically cannot get Part D in addition to Medicare Advantage (Part C) so make sure your plan includes prescription coverage if you need it.

When Deductions Start

Deductions start when you get Medicare but can be delayed a month when coverage begins. You should get a notice from the SSA explaining the Medicare premium deduction amount to be taken from your payment. 

When you reach full retirement age and your SSDI converts to retirement benefits, deductions come from retirement. 

One-Time Adjustments or Deductions

If your premium deduction is delayed or you have a late enrollment penalty, you may have a larger one-time deduction from your monthly payment. If you have a deduction that doesn’t make sense, contact the SSA for more information.

If You Get a Medicare Bill Instead of a Deduction

Medicare bills you when there’s not enough SSDI benefit for withholding. This may happen when you’re repaying an overpayment or SSDI benefits are paused.

Typically, Medicare bills for Part B quarterly (every three months) and monthly for Part A and Part D. You can pay Medicare premiums online, send checks, or set up automatic withdrawals.

Net Payment Examples

Example 1: Part B Deducted from SSDI

Your SSDI benefit is $1,600. Your Part B premium is $203. Your net SSDI payment is $1,397. 

Example 2: Part B Plus Part D Premiums Withheld

Your SSDI benefit is $1,600. Your Part B premium is $203. Your Part D plan premium is $34. Your net SSDI payment is $1,363. 

Income-Related Premium Surcharge

Your Medicare premiums may be higher than the standard fee if you or your family report high income on taxes, which can trigger an income-related monthly adjustment amount (IRMAA) surcharge. See current income brackets and surcharges. It’s based on tax returns from the prior two years.

Help Paying Premiums

While this article is written mostly about SSDI, you also get Medicare benefits when you receive Supplemental Security Income (SSI). SSI is for people with disabilities and limited income and resources.

Programs That Help with Medicare Costs

There are federal and state programs, including the Medicare Savings Program, that can help you pay insurance costs. These include Medicaid, the Medicare Savings Program, and your State Health Insurance Assistance Program (SHIP). 

Apply for extra help here. You won’t have to pay an enrollment penalty for a delay of Part D coverage if you’re applying for help.

Troubleshooting if the Deduction Looks Wrong

Step 1: Identify What Changed

Start with the first month your deposit changed. Then gather the documents that explain what was taken out, including your:

  • SSA notice about Medicare withholding
  • Medicare bill, if you received one
  • Premiums for Part C or Part D
  • Bank deposits or a copy of SSDI checks for the months in question

Step 2: Contact the Right Place

SSA handles questions about Medicare withholding from your benefit and income-based premium decisions. Medicare handles questions about your plan(s) and withholding or billing options. For questions about a Medicare Advantage premium, Part D coverage, or plan billing, contact your plan’s provider.

FAQs

Is Part B always deducted from SSDI?

The Part B premium is usually deducted automatically from SSDI once Medicare begins. You may be billed instead if there’s not enough SSDI to cover withholdings.

Can Part C or Part D be deducted too?

Yes, but only if you arrange it through your plan. If you did not request Medicare withholding for that plan, the plan may bill you instead. 

Why did I get a bill if I expected it to be deducted?

You may be billed when there’s not enough SSDI or SSI benefit to cover the premium. This happens when your benefit amount is low or you’re repaying an overpayment.

Why was my deduction bigger this month?

A larger one-time deduction can happen if your deduction was delayed or you have a penalty fee. Find the SSA notice explaining the larger deduction or contact the SSA for details.

Who do I contact if I think the deduction amount is wrong?

Contact SSA for Part B withholding questions and notices about income-based premiums. Contact Medicare or your plan for questions about bills and payments.
