2. Medicare Coverage & Hospital Access

- Out‑of‑pocket obligation: Generally, 20% of Part B services plus hospital deductibles.

b) Medicare Advantage (Part C)
- Private insurers manage MA plans and determine network providers and preauthorization requirements.
- Some top cancer centers may not accept particular MA plans, particularly if those plans prioritize cost containment.

One Redditor shared:
“All those places [Mayo, MD Anderson, MSK, Dana‑Farber] do not take Part C or Medicare Advantage plans… With Medigap it would most likely come out cheaper”
Having a Medigap (Medicare Supplement) plan alongside Original Medicare can significantly reduce out-of-pocket costs—something especially beneficial in cancer care.

3. Private Insurance Challenges
- Many top cancer hospitals do not accept ACA Marketplace (individual) plans due to high treatment costs and narrow network design.
Houston Chronicle - Company-sponsored PPO plans (especially from large insurers like Blue Cross Blue Shield) may provide broader national network access and better cancer center acceptance—but details vary by employer and plan.

- If using MA plans, opt for large PPOs with wide provider networks and call hospitals to verify current acceptance.
- Avoid ACA Marketplace plans for highly specialized care; they often exclude such providers.

Conclusion
For cancer patients in 2025, the U.S. maintains some of the world’s top facilities—MD Anderson, Memorial Sloan Kettering, Mayo Clinic, and others. While these centers offer outstanding care, insurance type decisively affects access. Original Medicare with Medigap ensures maximum coverage flexibility and minimum cost barriers. Medicare Advantage and private ACA plans may restrict choices or slow authorization.
