Medicare Advantage, or Medicare Part C, is an alternative to Original Medicare’s Part A and B hospital and medical insurance. In contrast to Original Medicare that provides the same services to all beneficiaries for a set monthly premium, Medicare Advantage plans are offered by private insurance companies. Most Part C plans provide extra benefits beyond the basic Part A and B services required by Medicare and have varying monthly costs. The additional benefits often included in Medicare Advantage plans are vision, hearing and dental care and prescription drug coverage. 

In 2020, approximately 39% of Medicare beneficiaries in the U.S. were enrolled in a Medicare Advantage plan, which was up by 8% from 2018. Nationwide enrollment is expected to reach 50% by 2029, according to research from the Kaiser Family Foundation, but enrollment rates vary from state to state. In Colorado, 43% of Medicare beneficiaries have Medicare Advantage, while the neighboring state of Utah has 39% and Wyoming just 3% enrollment. Alaska has the lowest number of enrollees at 1%, and Hawaii has the highest rate of enrollment at 47%.  

There are several types of Medicare Advantage plans, and their availability depends on the insurer and location. In Colorado, seniors can have a choice of HMO, PPO, PFFS or SNP plans. This guide describes each of these Medicare Advantage plans, and provides information about when an individual can enroll and prescription drug coverage. We’ve also included a list of resources that can help Colorado seniors understand their coverage options and how to choose the right plan for their needs.

About Medicare Advantage Plans in Colorado

Types of Medicare Advantage Plans

There are four main types of Medicare Advantage plans available in Colorado, depending on the county: Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), Private Fee-for-Service (PFFS) and Special Needs Plans (SNPs).

Health Maintenance Organizations (HMOs)

Health Maintenance Organizations, or HMOs, give plan members access to a network of doctors and medical facilities for their health care services. Enrollees must choose a primary care physician from within the network, and visits to specialists require PCP referrals. These restrictions keep HMO premiums low, and the plans usually have a low or zero deductible. Members who receive services from outside their plan’s provider network may be responsible for the entire cost of care, although out-of-network emergency services may be covered.

Preferred Provider Organizations (PPOs)

PPOs are similar to HMOs in that they have a contract with a network of doctors, hospitals and health care providers who agree on a set fee schedule for the services they provide to members. The main differences with PPOs are that members may choose to see a physician or facility outside of their network at a higher cost, and referrals often aren’t needed to see a specialist. This greater flexibility typically translates to higher premiums, and most PPO plans require that members meet a higher deductible before receiving coverage for their health care costs.

Special Needs Plans (SNPs)

SNPs provide health care coverage for groups of individuals who have specific medical needs. There are three types of SNPs offered in Colorado: Chronic condition SNPs (C-SNP), dual-eligible SNPs (D-SNP) and institutional SNPs (I-SNP). By law, SNPs must include prescription drug coverage so enrollees have consistent access to the medications used to control their conditions. To enroll in an SNP, an individual must qualify for the group the plan serves, be enrolled in Medicare Parts A and B and live in the plan’s service area. 

Private Fee-for-Service Plans (PFFS)

Unlike a PPO or HMO, PFFS plans don’t limit enrollees to receiving services from providers within a certain network. Instead, a PFFS plan pays a set amount to individual health care providers for services received by its members. Plan members may choose any physician or medical facility, as long as the provider agrees to accept the plan’s payments terms. There are no requirements to choose a primary care physician, and members may visit specialists without a referral. Not all providers are willing to accept the terms of a PFFS, and premiums are usually higher for these plans.

Enrollment and Eligibility for Medicare Advantage in Colorado

Prior to enrolling in Medicare Advantage, seniors must first be enrolled in Original Medicare. Anyone who is eligible for Medicare Parts A and B is also eligible to enroll in Medicare Advantage. However, certain Medicare Advantage plans, such as SNPs, may have additional eligibility requirements.

Medicare Advantage has specific enrollment periods. One can only join a Medicare Advantage plan during the following periods:

  • Initial Coverage Election Period: This is the 7-month period during which everyone is eligible to enroll in a Medicare Advantage plan. The period spans from 3 months before the month of one’s 65th birthday to 3 months after one’s birthday month.
  • Annual Election Period (AEP): Also referred to as the Open Enrollment Period, the AEP runs from October 15-December 7 each year. During this period, anyone can enroll in Medicare Advantage for the first time or change to a new plan.
  • Medicare Advantage Open Enrollment Period: From January 1-March 31 each year, anyone who is already enrolled in Medicare Advantage can switch to a different plan, or disenroll and switch back to Original Medicare. This period is not open to anyone who is not currently enrolled in Medicare Advantage.
  • General Enrollment Period: In some circumstances, one can join Medicare Advantage between April 1-June 30. This enrollment period only applies to those who enrolled in Medicare Part B for the first time during Medicare’s Open Enrollment Period (January 1-March 31).

Additionally, Medicare Advantage plan participants can change their plan outside of these enrollment periods under certain qualifying circumstances, such as moving to a new state.

Prescription Drug Coverage

In Colorado, Medicare Advantage plans that include the cost of prescription medications are called Medicare Advantage prescription drug plans or MA-PDs. To be eligible for enrollment in an MA-PD, an individual must be enrolled in a Medicare Advantage program. These prescription drug plans cover most commonly prescribed medications but don’t cover over-the-counter medications, vitamins or drugs not included on the plan’s formulary list. Some Medicare Advantage plans bundle health and prescription coverage and only charge one monthly premium payment. Other plans require two separate premium payments. 

Seniors with Medicare Advantage plans that don’t include prescription coverage may be able to enroll in a stand-alone Medicare Part D plan. Colorado residents can’t enroll in a stand-alone Part D plan while enrolled in an MA-PD plan. Anyone who does risks being dropped from their Medicare Advantage plan and placed back on Original Medicare.
