Understanding Memorial Sloan Kettering and Medicare Coverage Basics

Memorial Sloan Kettering Cancer Center (MSK) is one of the largest and oldest private cancer hospitals in the United States, located in New York City. Founded in 1884, it has grown into a major medical institution with multiple locations across the Northeast. The hospital is known for its research programs, specialized cancer treatments, and clinical trials. Because MSK is a private hospital rather than a government-run facility, understanding how Medicare coverage works there requires learning about several key concepts.

Medicare is a federal health insurance program administered by the Centers for Medicare & Medicaid Services (CMS). It primarily serves people age 65 and older, though some younger individuals with disabilities or end-stage renal disease may also receive Medicare coverage. The program consists of different parts: Part A covers hospital services, Part B covers outpatient medical services, Part D covers prescription drugs, and supplemental coverage options exist through private insurers.

When you receive care at Memorial Sloan Kettering with Medicare coverage, the hospital must follow Medicare's rules about billing, payment rates, and coverage policies. Medicare does not "cover" individual hospitals—instead, it covers specific medical services and treatments based on medical necessity. This means that having Medicare does not guarantee coverage for every service MSK provides, but rather coverage depends on whether that particular service meets Medicare's criteria.

MSK participates in Medicare as an in-network provider, which means the hospital has agreed to accept Medicare's payment rates for covered services. This is different from out-of-network providers, where costs may be higher. Understanding this distinction matters because it affects your out-of-pocket costs.

Practical Takeaway: Before scheduling treatment at MSK, confirm with the hospital's billing department that your specific Medicare plan and the proposed treatment are compatible. Ask whether the hospital considers your treatment in-network under your plan, as this directly affects your costs.

How Medicare Part A and Part B Cover Hospital Services at MSK

Medicare Part A is hospital insurance that covers inpatient care, including stays at hospitals like Memorial Sloan Kettering. If you are admitted to MSK as an inpatient for cancer treatment, surgery, or other conditions, Part A generally covers the hospital facility, nursing care, meals, and standard room charges. In 2024, Medicare Part A beneficiaries pay a deductible of $1,632 for each benefit period (the amount changes yearly). After you meet the deductible, Medicare covers most of the hospital costs, though you may still have daily copayments depending on the length of your stay.

Medicare Part B covers outpatient services, which includes doctor visits, diagnostic tests, treatments, and procedures performed outside a hospital inpatient setting. Many cancer patients at MSK receive Part B-covered services such as chemotherapy infusions in outpatient clinics, radiation therapy, laboratory tests, imaging scans (CT, MRI, PET scans), and consultations with oncologists. The Part B deductible for 2024 is $240 per year. After meeting this deductible, you typically pay 20% of the Medicare-approved amount for covered services, with Medicare paying the remaining 80%.

It is important to understand the difference between inpatient and outpatient status, as this affects coverage. If you are admitted to MSK's hospital bed as a patient, Part A applies. If you visit an MSK outpatient clinic or surgical center for a procedure and are discharged the same day, Part B applies. Sometimes patients receive observation care, which is a middle ground—you may be in a hospital bed but not officially admitted as an inpatient. Observation status affects what Medicare covers and what you pay.

Specific services covered by Parts A and B at MSK may include tumor removal surgery, chemotherapy drugs administered in the hospital or clinic, radiation therapy planning and treatment, pathology services, oncology consultations, diagnostic imaging, laboratory work, and supportive care services. However, not every service is covered. For example, certain experimental treatments, some newer medications not yet approved by Medicare, or services deemed not medically necessary may not be covered.

Practical Takeaway: Before undergoing any major procedure or treatment at MSK, request a Medicare benefits review from the hospital's financial counselor. Ask specifically whether the treatment is covered under Part A or Part B and what your out-of-pocket costs will be. This prevents surprise bills later.

Understanding Medicare Supplement Plans and MSK Coverage

Many Medicare beneficiaries purchase Medigap (Medicare Supplement) insurance policies from private insurers. These plans work alongside Original Medicare (Parts A and B) to cover costs that Medicare does not pay, such as deductibles, copayments, and coinsurance. If you have a Medigap plan from carriers like UnitedHealth, Cigna, Aetna, or other insurers, that plan's coverage rules apply in addition to Medicare's rules when you receive care at MSK.

Different Medigap plans (labeled A through N) offer different levels of coverage. For example, Plan G covers Part B coinsurance, which means it pays the 20% that Medicare does not cover for outpatient services. Plan F (no longer sold to those newly Medicare-eligible after 2020) covered the Part B deductible as well. The specific plan you hold determines what additional costs the Medigap insurer will pay at MSK.

When you receive care at MSK with a Medigap plan, you should expect the following process: First, Medicare processes the claim and determines what it will pay based on its approved amount. Second, your Medigap plan processes the remaining balance and pays according to your plan's terms. You are responsible for any costs that neither Medicare nor Medigap covers. Most MSK providers are in-network for Medigap plans, though you should verify this before treatment.

It is important to note that Medigap plans have no network restrictions in most states—meaning you can use any provider that accepts Medicare and any Medigap plan. However, some Medigap insurers may have specific rules or requirements about prior authorization for certain treatments at MSK. Always contact your Medigap insurer before major procedures to understand your coverage and any authorization requirements.

Practical Takeaway: If you have a Medigap plan, review your policy documents before scheduling treatment at MSK, or call your Medigap insurer's customer service line to confirm coverage for your planned treatment. Ask whether any prior authorization is required and what your out-of-pocket costs will be after both Medicare and your Medigap plan pay.

Medicare Advantage Plans and Coverage at MSK

Some Medicare beneficiaries choose Medicare Advantage plans (Part C), also called MA plans, instead of Original Medicare. These are insurance policies sold by private companies like Humana, UnitedHealth, Anthem, and others. Medicare Advantage plans provide the same coverage as Original Medicare (Parts A and B) plus typically include prescription drug coverage (Part D) and often additional benefits like dental or vision care. However, MA plans use networks of healthcare providers, and coverage rules differ significantly from Original Medicare.

MSK's participation in Medicare Advantage networks varies by plan and region. Many major MA plans in the New York area include MSK as an in-network provider because of the hospital's prominence in cancer care. However, not all Medicare Advantage plans contract with MSK. Some plans may designate MSK as out-of-network, which results in much higher out-of-pocket costs for you. A few MA plans may not cover MSK at all except for emergency services.

If your Medicare Advantage plan covers MSK in-network, your costs are typically lower than out-of-network coverage. For example, you might pay a copay for an office visit or a percentage of the cost for a procedure. However, Medicare Advantage plans often require prior authorization before you receive treatment, especially for surgeries, expensive imaging studies, or chemotherapy. This means MSK must contact your MA plan before performing the service to receive approval. Without prior authorization, the service may not be covered, and you could owe the full cost.

Another important feature of MA plans is the out-of-pocket maximum. Once you reach this annual limit (often $6,700 to $7,000 in 2024), the plan pays 100% of covered services for the remainder of that year. For cancer patients receiving ongoing treatment, reaching the out-of-pocket maximum may happen relatively quickly, potentially saving you money later in the year.
