Which of the following is true regarding Medicare's coverage of screening services?

Medicare provides coverage for a variety of screening services, and one of the key features of this coverage is that many of these services are provided at no cost to the beneficiary. This means that eligible individuals can receive preventive screenings without having to pay out-of-pocket, which supports the program's goal of promoting preventive healthcare.

For example, services like mammograms, colonoscopies, and certain cardiovascular screenings are included under this provision. Beneficiaries can take advantage of these screenings to detect potential health issues early without incurring cost barriers, which can help in timely diagnosis and treatment.

While there are age-related criteria for some screening services, such as certain tests being more commonly recommended for older adults, the essential aspect of coverage at no cost holds true for many preventive services that Medicare covers.
