CMS states that Medicare beneficiaries enrolled in the Qualified Medicare Beneficiary (QMB) group have no legal obligation to pay Medicare Part A or Part B deductibles, coinsurance or copayments for Medicare-covered items and services. Medicare providers and suppliers are prohibited from billing QMB patients for that cost sharing.
This protection is especially important for expensive Part B infusions and injections, where 20% coinsurance can otherwise look enormous.
- Confirmed QMB enrollment
- Medicare Summary Notice or EOB
- Whether the medicine/service was Medicare-covered
- Provider bill amount
- Which line is deductible/coinsurance/copay
- Provider billing-office correction request
- Escalation to Medicare/SHIP if improper billing continues
Make sure the billing office knows the patient is QMB
Providers can miss or misunderstand QMB status. If a bill arrives for Medicare cost sharing, contact the provider and identify the QMB protection rather than simply setting up a payment plan.
Keep the Medicare Summary Notice, Medicaid/QMB information and provider bill together so the account can be corrected.
The provider’s Medicaid payment is not the patient’s balance
States have different rules for how much Medicaid pays toward Medicare cost sharing, and sometimes Medicaid pays little or nothing beyond Medicare. CMS is clear that the provider still cannot shift the unpaid Medicare cost sharing to the QMB beneficiary.
The billing dispute is therefore not solved by telling the patient Medicaid did not pay the full coinsurance.
Separate QMB protection from coverage of a non-covered service
QMB protection applies to Medicare cost sharing for Medicare-covered items and services. If the underlying service is not covered by Medicare, a different notice/liability question may arise.
For a denied Part B medicine, resolve the coverage decision first; for an allowed Medicare claim with prohibited QMB balance billing, resolve the billing protection.
Use the source that actually controls your case
MedicineCostHelp can organize the problem, but the member-specific plan, Medicare program, provider billing record or assistance program makes the actual decision. Save written determinations and reference numbers so the next person does not have to reconstruct the case from scratch.
