Is a CT scan worth it?

CT scans provide valuable medical information, but can also increase the risk for cancer. Computed tomography (CT) is a valuable medical imaging technique that uses x-rays and a computer to generate a 3D image of a person's insides. CT can improve health outcomes by aiding diagnosis in a variety of situations.

What won't Medicare pay for?

Key exclusions also include most personal care (bathing, dressing), acupuncture (except for chronic lower back pain), and services from non-participating providers. 

What are the biggest mistakes people make with Medicare?

The biggest Medicare mistakes involve missing enrollment deadlines, leading to lifelong penalties; failing to compare plans annually, causing overspending; assuming coverage includes everything (like long-term care); not getting a Part D drug plan or Medigap policy when needed; and ignoring the Annual Notice of Change (ANOC) for Medicare Advantage plans, says AARP, UnitedHealthcare, and the National Council on Aging (NCOA). People also err by not understanding the difference between Original Medicare and Medicare Advantage, delaying enrollment to avoid paying premiums, or assuming their spouse is automatically covered. 

Is it better to go on Medicare or stay on private insurance?

Neither Medicare nor private insurance is universally "better"; the best choice depends on individual needs, but Medicare often offers lower admin costs, standardized coverage, and potentially lower premiums for individuals (especially Part A), while private plans excel at covering dependents and often have out-of-pocket caps, though sometimes with higher overall costs and network restrictions. Original Medicare (Parts A & B) has no spending limit, while private plans and Medicare Advantage (Part C) (run by private companies) typically do, making them potentially safer for high-need users.

The most common reasons for a CT scan are to quickly diagnose injuries from trauma (like car accidents), find tumors, infections, or blood clots, and to investigate abdominal pain or issues with the brain/spine, often to guide urgent care, surgery, or cancer treatment. Doctors use CT scans for fast, detailed views of bones, soft tissues, and blood vessels to pinpoint the source of pain, bleeding, or other problems when time is critical.
