What DC QMB Covers — Copays, Deductibles, and Cost-Sharing Explained

Most people think QMB just pays the Part B premium. It does — but that's the beginning, not the full picture. QMB is the only Medicare Savings Program tier that covers the entire range of Medicare cost-sharing, and in DC's expanded version, it reaches seniors that most states would never qualify.

Every Cost QMB Covers

Here's what the District pays once QMB is approved, using 2026 CMS rates:

Part B premium: $202.90/month — deducted directly from Social Security in most cases. QMB stops the deduction and reimburses any months taken between the QMB start date and when SSA processes the change.

Part A premium: Up to $565/month for seniors without 40 quarters of work history ($311/month with 30–39 quarters). DC's Part A buy-in covers this in full, year-round, with no late enrollment penalty.

Part B annual deductible: $283 in 2026. With QMB, this is $0.

Part A hospital deductible: $1,736 per benefit period. With QMB, $0.

Part A hospital coinsurance (days 61–90): $434/day. With QMB, $0.

Skilled nursing facility coinsurance (days 21–100): $217/day. With QMB, $0.

Part B coinsurance: Normally 20% of the Medicare-approved amount for most outpatient services. With QMB, $0.

Automatic Full Extra Help: QMB triggers deemed eligibility for the Part D Low-Income Subsidy. Drug deductible drops to $0, premiums on benchmark plans are $0, and copays cap at $5.10 generic / $12.65 brand-name.

The Balance Billing Protection

This is the part most people don't know about until they need it. Under Section 1902(n)(3)(B) of the Social Security Act (42 U.S.C. § 1396a(n)(3)(B)), every Medicare-enrolled provider is prohibited from billing QMB enrollees for any Part A or Part B deductibles, coinsurance, or copayments. This applies to:

• Original Medicare (Fee-for-Service) providers
• Medicare Advantage (Part C) plans
• Providers who don't participate in DC Medicaid
• Providers outside DC's Medicaid network

Even when DC Medicaid pays the provider $0 on the cost-sharing claim (because the Medicaid rate is lower than the Medicare allowed amount), the provider cannot bill the QMB enrollee for the balance. That's the "lesser-of" payment rule — and it's legally binding regardless of what the provider's billing office tells you.

If a provider sends a bill for Medicare cost-sharing, don't pay it. Present the QMB approval letter, cite 42 U.S.C. § 1396a(n)(3)(B), and demand a zero-balance statement. If they refuse, escalate to the DC Health Care Ombudsman at 1-877-685-6391 or report to 1-800-MEDICARE.

What QMB Does Not Cover

QMB covers Medicare costs. It doesn't provide full Medicaid benefits. Specifically, QMB alone does not include:

• Adult dental care
• Vision services
• Personal care aides or home health beyond what Medicare covers
• Non-emergency medical transportation
• Long-term care services

Those require full Medicaid (ABD — Aged, Blind, or Disabled) or the EPD waiver, both of which have lower income limits and an asset test. A senior can have both QMB and full Medicaid simultaneously if they meet both sets of eligibility rules.

QMB also doesn't cover Part D drug copays beyond Extra Help levels. Those $5.10/$12.65 copays are the QMB/Extra Help copay — not $0 (except once annual out-of-pocket spending hits $2,100, at which point copays drop to $0 for the rest of the year).

The Numbers for a Typical DC Senior

A 70-year-old DC resident with $2,800/month in Social Security and a small pension, no hospital stays this year, one ER visit, and five monthly prescriptions:

Without QMB:

• Part B premium: $2,434.80/year
• Part B deductible: $283/year
• 20% coinsurance on outpatient services: varies, but easily $500–$1,000/year
• Part D drug costs: $615 deductible + full copays
• Total exposure: $4,000–$5,000+/year

With QMB:

• Part B premium: $0
• Part B deductible: $0
• Coinsurance: $0
• Part D deductible: $0, copays capped at $5.10 generic / $12.65 brand-name
• Total exposure: up to $759/year for five monthly brand-name prescriptions; lower for generics

DC's income threshold for QMB is $4,010/month for an individual. No asset test. At $2,800/month, this senior qualifies with wide clearance.
