Blue Cross Medicare Advantage Enrollment Process

Annual Enrollment is when most people make their changes. If your current plan suits you, no action is needed, since it renews on its own. Even so, review your Annual Notice of Change, as networks, drug lists, copays and premiums may all change on January 1.

A non-renewal notice should have reached you in early October if your plan will not be available in your county for 2027. You are not cut off immediately: coverage runs through December 31, 2026, giving you time to make a choice.

By September 30, plans have to send the Annual Notice of Change. Because it spells out exactly how your plan changes on January 1, it is the most useful document you receive each fall.

Changing plans outside the fall and early-year windows generally requires a Special Enrollment Period. Typical reasons include:

Every Special Enrollment Period has its own deadline, so move quickly once the event occurs.

Prior authorization is required by most Medicare Advantage plans for certain services, including some surgeries, advanced imaging, skilled nursing stays and certain drugs. The request usually comes from your doctor, but check whether a planned service needs approval so you are not caught off guard by a denial.

You or your doctor may appeal a denied request. Plans must decide within deadlines set by Medicare rules, and those deadlines are shorter when a delay could seriously harm your health.

Emergency and urgent care are covered by every Medicare Advantage plan anywhere in the U.S., whether in or out of network, and emergencies need no prior approval. Routine care while traveling is another matter: HMOs generally won’t cover it, and PPOs cover out-of-network care but charge more.

Do you spend several months a year away from home? Ask every plan how it covers care at your second location, since this is among the most frequent reasons people change plans mid-year.

You have the right to appeal when your plan denies a drug, a service or payment for care. Instructions are in the plan’s denial notice. Appeals go through several levels, beginning with the plan and moving on to independent reviewers.

Issues that are not about coverage, like wait times or customer service, can be raised by filing a grievance with the plan. For help, you can also reach 1-800-MEDICARE or your State Health Insurance Assistance Program.

Unlike the plan details, the Part B premium has not been released. It is normally announced by CMS in November. For 2027, the 2026 Medicare Trustees Report projects a standard premium of about $209.50 a month and a deductible of about $292, compared with $202.90 and $283 in 2026. Medicare Advantage members still pay it.

Missing the Annual Enrollment deadline means your current plan automatically renews for 2027, including the changes listed in your Annual Notice of Change. Medicare Advantage members get another opportunity from January 1 to March 31, 2027, to move to a different Medicare Advantage plan or go back to Original Medicare and add a Part D plan.

Telehealth visits for some services may be covered by many Medicare Advantage plans, in some cases with a lower copay than an in-person visit. It is handy for follow-ups and small problems, but you still need to confirm your regular doctors are in network.

Special Needs Plans (SNPs) are Medicare Advantage plans designed for particular groups. Their benefits, networks and drug lists are shaped around their members, and many provide care coordinators. Even as large insurers cut PPOs for 2027, Special Needs Plans are among the few places they are adding plans.
