Medicare Part A and Part B Costs on SSDI

Medicare Part A is premium-free for nearly all SSDI recipients, while Medicare Part B requires a standard monthly premium of $185.00 in 2026 that is automatically deducted from your SSDI benefit check. In addition to monthly premiums, beneficiaries are responsible for annual deductibles, copayments, and coinsurance under 42 CFR Part 409 and Part 410.

When you transition onto Medicare through Social Security Disability Insurance, understanding your out-of-pocket healthcare expenses is vital for managing your monthly household budget. While Original Medicare provides robust national coverage for inpatient hospital stays, outpatient medical appointments, and diagnostic procedures, it is not free healthcare. Being aware of the specific cost structures, statutory deductibles, and available financial relief programs allows you to avoid unexpected medical debts while receiving required care.

Medicare Part A Costs: Hospital Insurance

Medicare Part A covers inpatient hospital stays, care in skilled nursing facilities, hospice care, and some home health services.

Premium-Free Part A Eligibility

Under Title II of the Social Security Act and federal regulation 42 CFR 406.10, individuals entitled to SSDI receive premium-free Medicare Part A. Because SSDI eligibility requires a verified work history with Social Security tax contributions, disabled workers who accumulated at least 40 quarters of coverage (10 years of work in covered employment) pay $0 per month for Part A in 2026.

In the rare event that a disabled adult child or widow qualifies for SSDI without personal quarters of coverage, their entitlement is based on the earnings record of an insured parent or deceased spouse, which also grants premium-free Part A under POMS HI 00801.001.

Inpatient Hospital Deductible and Coinsurance

Although Part A carries no monthly premium, beneficiaries must pay cost-sharing charges for hospitalizations under 42 CFR Part 409.

Under CMS determinations for 2026, the Part A inpatient hospital deductible is $1,712 per benefit period. A benefit period begins the day you enter a hospital or skilled nursing facility and ends after you have been out of inpatient care for 60 consecutive days under 2026 guidelines.

If a hospital stay extends beyond 60 days in a single benefit period, beneficiaries must pay daily coinsurance under 2026 CMS rates:

• Days 1 through 60: $0 coinsurance per day after meeting the $1,712 deductible in 2026.
• Days 61 through 90: $428 coinsurance per day in 2026.
• Days 91 through 150: $856 coinsurance per day for each lifetime reserve day used in 2026.
• Beyond 150 days in 2026: The beneficiary pays all hospital costs.

For skilled nursing facility stays following a qualifying hospital admission, days 1 through 20 require $0 coinsurance, while days 21 through 100 require a daily coinsurance payment of $214 in 2026.

Medicare Part B Costs: Medical Insurance

Medicare Part B covers medically necessary outpatient physician services, outpatient hospital care, physical therapy, durable medical equipment, mental health treatment, and preventative visits.

Standard Monthly Part B Premium

Under Section 1839 of the Social Security Act (42 U.S.C. 1395r) and 42 CFR 408.20, Medicare Part B requires a monthly premium from all enrollees. For the 2026 calendar year, the standard monthly Part B premium is $185.00 per month, reflecting an increase from the $174.70 monthly premium established in 2025.

Under 20 CFR 404.1805 and POMS HI 01001.010, the Social Security Administration automatically deducts this $185.00 premium from your monthly SSDI payment in 2026. For example, if your gross monthly disability benefit is $1,600 in 2026, your net direct deposit will be $1,415.00 after the 2026 Part B premium is withheld.

Part B Deductible and Coinsurance

In addition to the monthly premium, Part B beneficiaries encounter deductibles and coinsurance under 42 CFR Part 410:

• Annual Part B Deductible: In 2026, the annual deductible for Medicare Part B is $257, compared to $240 in 2025. You must pay this initial amount out of pocket each calendar year before Medicare begins paying for outpatient services.
• Standard 20% Coinsurance: Once you satisfy your $257 deductible in 2026, you generally pay 20% of the Medicare-approved amount for most doctor services, outpatient therapy, and durable medical equipment, with Medicare paying the remaining 80%.

Unlike commercial health plans, Original Medicare in 2026 does not have an annual out-of-pocket maximum on 20% coinsurance expenses, making supplementary coverage important for claimants with extensive medical needs.

Income-Related Monthly Adjustment Amount (IRMAA)

Claimants with higher household incomes prior to becoming disabled may be subject to an additional surcharge known as the Income-Related Monthly Adjustment Amount (IRMAA).

Under Section 1839(i) of the Social Security Act (42 U.S.C. 1395r(i)) and federal regulation 20 CFR 418.1101, the Social Security Administration evaluates your modified adjusted gross income (MAGI) from two years prior to determine your current Part B premium. For 2026 premium calculations, SSA examines tax returns filed for the 2024 tax year.

Under 2026 IRMAA brackets:

• Individuals with a 2024 tax income over $109,000, or married couples filing jointly with an income over $218,000, pay an additional monthly surcharge in 2026 ranging from $74.00 to $444.00 on top of the standard $185.00 Part B premium.
• Higher-income beneficiaries also pay an additional monthly surcharge for Medicare Part D prescription drug coverage under 20 CFR 418.2101.

Appealing an IRMAA Surcharge with Form SSA-44

Because IRMAA relies on tax information from two years earlier, SSDI recipients frequently receive an unfair high-income determination based on earnings from when they were still working full-time.

Under 20 CFR 418.1205, you have the legal right to request a new initial determination using Form SSA-44 (Medicare Income-Related Monthly Adjustment Amount for Life-Changing Events). Recognized life-changing events include:

• Work stoppage or work reduction due to disability
• Marriage, divorce, or annulment
• Death of a spouse
• Loss of income-producing property due to disaster

By submitting Form SSA-44 along with documentation of your work stoppage and an estimate of your current, reduced income, Social Security can recalculate your 2026 Part B premium based on your present financial circumstances, eliminating the high-income surcharge.

Managing Prescription Drug Costs and Coverage Gaps

Original Medicare (Parts A and B) does not cover retail prescription drugs. To obtain medication coverage, beneficiaries must enroll in a Medicare Part D plan or choose a Medicare Advantage plan (Part C) that includes drug benefits under 42 CFR Part 423.

In 2026, Part D prescription plans feature an annual out-of-pocket spending cap of $2,000 enacted under the Inflation Reduction Act, protecting beneficiaries from catastrophic medication bills once they reach that threshold. Monthly plan premiums for Part D vary by private insurer, generally averaging between $30 and $50 per month in 2026.

Beneficiaries under age 65 who want to cover Original Medicare deductibles and the 20% Part B coinsurance in 2026 may explore Medicare Supplement Insurance (Medigap). However, federal law does not require private insurers to sell Medigap policies to individuals under age 65 who receive SSDI. Access and pricing for under-65 Medigap policies are governed by state law, with some states requiring insurers to offer at least one plan, while others permit underwriting denials or substantial rate markups.

Programs That Lower Medicare Costs for SSDI Claimants

SSDI recipients experiencing financial hardship have access to federal and state assistance programs that cover Medicare premiums and cost-sharing obligations:

1. Medicare Savings Programs (MSPs): Administered by state Medicaid agencies under 42 U.S.C. 1396a(a)(10)(E), programs like the Qualified Medicare Beneficiary (QMB) program pay your full $185.00 monthly Part B premium, along with Part A and Part B deductibles and coinsurance in 2026. Other programs, such as SLMB and QI, pay the $185.00 Part B premium for qualifying low-income individuals in 2026.
2. Extra Help (Low-Income Subsidy): Under 42 CFR 423.773, low-income SSDI beneficiaries qualify for federal assistance that eliminates Part D deductibles and caps generic drug copayments at $4.90 and brand-name drugs at $12.15 per prescription in 2026.

Beneficiaries can apply for Medicare Savings Programs through their state Medicaid agency or submit Form SSA-1020 directly to the Social Security Administration to request Extra Help.
