Many seniors do not receive recommended preventive and primary care, leading to less effective and more expensive treatments. For example, 20 percent of women aged 50 and over did not receive a mammogram in the past two years, and 38 percent of adults aged 50 and over have never had a colonoscopy or sigmoidoscopy. Seniors in Medicare must pay 20 percent of the cost of many preventive services on their own. For a colonoscopy that costs $700, this means that a senior must pay $140 — a price that can be prohibitively expensive. Under health insurance reform, a senior would not pay anything for a screening colonoscopy or other preventive services. Reform will eliminate any deductibles, copayments, or other cost-sharing for obtaining preventive services, making them affordable and accessible.
