Original Medicare's Missing Cap Can Crush You During Cancer Treatment
Original Medicare has no out-of-pocket maximum, leaving cancer patients exposed to unlimited 20% cost-sharing that can spiral fast.
Most people assume Medicare means covered. It doesn't mean *protected*. Original Medicare — Parts A and B — has no out-of-pocket maximum, and that single missing feature can turn a cancer diagnosis into a financial catastrophe on top of a medical one.
Here's the math that matters: Medicare typically covers 80% of approved costs, and you're on the hook for the remaining 20%. No cap. No ceiling. If your cancer treatment runs $500,000 in a year — and modern oncology bills can absolutely reach that — you're personally exposed to $100,000 or more. The 20% doesn't shrink just because the total gets enormous.

This is the tradeable insight most pre-retirees miss when they're planning their healthcare budget. You can model Social Security income, sequence-of-returns risk, even long-term care — but an uncapped medical liability is the variable that can zero out a portfolio in a single bad year. Cancer is one of the highest-cost diagnoses in the system, and it hits without scheduling an appointment.
The standard workaround is a Medicare Supplement plan, also called Medigap. These private policies layer on top of Original Medicare and can cap or eliminate that 20% exposure entirely. The tradeoff is a monthly premium you pay whether you're healthy or not. Medicare Advantage plans, the all-in-one alternative, do carry out-of-pocket maximums — but network restrictions and prior authorization requirements come with that deal.
The bottom line: if you or someone you care about is on Original Medicare with no supplement, the exposure is real, unlimited, and worth fixing before a diagnosis forces the conversation. Continue reading at Yahoo Finance.
