Original Medicare Lacks Out-of-Pocket Maximum, Posing Financial Risks for Cancer Patients
Original Medicare does not have an annual out-of-pocket maximum, which can lead to significant financial burdens for beneficiaries, particularly those facing serious illnesses like cancer. After the 2026 Part B deductible of $283, Medicare generally covers 80% of approved costs for physician services and outpatient treatments, leaving beneficiaries responsible for the remaining 20%. This lack of a spending cap means that in a year with high medical expenses, such as cancer treatment, patients could face substantial out-of-pocket costs. For example, a cancer patient with $150,000 in Part B services could owe $30,000 in coinsurance alone.
