Colorado seniors looking into their health coverage options or seeking a change from their current Medicare plans may have the option of enrolling in Medicare Advantage, also known as Part C. Unlike traditional Medicare that’s provided through the federal government, Medicare Advantage is offered by private insurance companies. Plans are required to offer the same coverage as Original Medicare but are often enhanced with additional benefits to compete with other insurance companies. For example, prescription coverage through traditional Medicare requires enrollment in Part D with additional costs. Many Medicare Advantage Plans already include prescriptions, keeping this important benefit under the same premium. Other possible coverage options include vision, dental and sometimes less common benefits, such as fitness and medical transportation.

There are some important details to consider when comparing Medicare Advantage to original Medicare. Like many traditional health insurance plans, most Medicare Advantage Plans use a network of providers and physicians. Seeing someone outside of this network will incur additional costs. Seniors who travel frequently within the U.S. may be limited on finding in-network care outside of Colorado and could get more from a standard plan that covers care from any provider in the country that accepts traditional Medicare. Also, while having healthcare options bundled can reduce premium costs for many seniors, some plans could cost them more depending on the coverage included.

Regardless of these potential drawbacks, the number of Colorado seniors who choose Medicare Advantage has grown over the last year. Enrollment reached 48% of all eligible enrollees in 2022 but has increased to 51% in 2023, despite the number of eligible residents also increasing by 3.14%. That comes out to just over 500,000 seniors who get their benefits from Medicare Advantage in Colorado as of July of this year.

This guide is a must-read for Colorado seniors considering Medicare Advantage. It delves into Part C coverage, showcases state plans, explains eligibility, and provides application insights for a well-informed decision.

The Top 10 Medicare Advantage Plans in Colorado

Medicare Advantage offers seniors options when it comes to their healthcare, allowing them the same freedom of choice to shop for the best plan to fit their situation.

The table below lists the top 10 Colorado Medicare Advantage Plans, ranked by the number of people enrolled. Costs are provided as a range to cover differing plan options and the Medicare rating comes from actual enrollee experiences. The information provided is accurate as of July of 2023.

How Medicare Advantage Plans Work in Colorado

The graphic below provides details about the four most common types of Medicare Advantage Plans in Colorado.

What Medicare Advantage Plans Cover in Colorado

With exceptions for hospice care, clinical trials and new benefits that are introduced via legislation, Medicare Advantage must cover the same medically necessary services as Original Medicare. This means enrollees have access to all other services covered under Medicare Part A and Part B. Most Medicare Advantage plans also include prescription coverage, eliminating the need for enrollees to purchase a Part D drug supplement. Many providers even offer extra benefits, such as coverage for hearing aids or over-the-counter medications.

Eligibility for Medicare Advantage in Colorado

Medicare Advantage isn’t available to every resident of Colorado. To enroll, an individual must have Medicare Part A and Part B, choose a Medicare Advantage plan that’s available in their service area and meet other eligibility requirements. Enrollees must be at least 65 or have amyotrophic lateral sclerosis, end-stage renal failure or a disability that qualifies them for 24 consecutive Social Security or Railroad Retirement Board disability payments. To qualify for Medicare, an applicant must also be a U.S. citizen or lawful permanent resident.

Medicare doesn’t offer year-round enrollment, so it’s important for seniors to understand when they can sign up for the first time, switch Medicare Advantage Plans or switch from Medicare Advantage back to Original Medicare. The list below provides details on Medicare’s enrollment periods.

  • Initial Coverage Election Period: This is the initial 7-month period, coinciding with one’s 65th birthday, during which everyone is eligible to enroll in a Medicare Advantage plan.
  • Annual Election Period (AEP): Also referred to as the Open Enrollment Period, this the time of year when anyone over 65 can enroll in Medicare Advantage for the first time or change to a new plan.
  • Medicare Advantage Open Enrollment Period: During this period, those who are already enrolled in Medicare Advantage can switch to a different plan or switch back to Original Medicare.
