Medicare doesn't publicly score plans on prior authorization burden, so there's no official ranking. However, prior authorization requirements vary by plan and change yearly. Checking a plan's Evidence of Coverage document is the most reliable way to understand how often authorizations are required.
Prior authorization means a plan requires your doctor to get approval before a service, procedure, or medication is covered. It's one of the most common frustrations people have with Medicare Advantage plans. Some plans require authorization for a long list of services. Others apply it more narrowly. Unfortunately, Medicare doesn't publish a simple comparison showing which plans use prior authorization most or least often. What you can do is read the Evidence of Coverage document for any plan you're considering. It's a detailed document, but it spells out which services need approval before you receive them. You can also ask your doctor's office which plans create the most administrative friction. Physicians and their billing staff deal with prior authorization daily and often have strong opinions about which plans are harder to work with. It's also worth noting that CMS, which is the federal agency that oversees Medicare, has been tightening rules around prior authorization in recent years, requiring faster response times and greater transparency. That means the landscape is shifting, and a plan's track record from a few years ago may not reflect how it operates today. Verify current details directly with the plan before enrolling.




Your doctors at Intermountain Health or University of Utah Health may have informal knowledge about which plans create the most delays for their patients. That's a genuinely useful signal. Utah's ADRC counselors, who provide free Medicare guidance through the SHIP program, can also help you read through plan documents if the details feel overwhelming.
For you, this means asking your specialist or primary care doctor which insurance plans cause them the fewest headaches, because that ground-level experience is often the most honest data available.
