The Ins and Outs of HMO Plans for Medicare Beneficiaries

As a Medicare beneficiary, you have a variety of health insurance options to choose from, including Medicare Advantage HMO plans. HMO (Health Maintenance Organization) plans are a popular choice for many people due to their lower out-of-pocket costs and emphasis on preventive care. However, understanding how HMO plans work can be confusing, especially if you're new to Medicare or health insurance in general. In this article, we'll take a closer look at HMO plans, including their structure, benefits, drawbacks, and how to choose the right plan for your needs. This guide will provide you with the knowledge and insights you need to make an informed decision.

How HMO Plans Work

Medicare Advantage plans come in several forms. The two most common forms are PPOs (Preferred Provider Organizations) and HMOs. Both are managed care health insurance plans, though HMOs have more structured or strict rules. HMOs typically require members to select a primary care physician (PCP) who serves as their primary point of contact and coordinator for all their medical care and treatment.

Under an HMO plan, you'll need to visit your PCP for routine care, such as checkups and basic health screenings. If you need to see a specialist, your PCP will provide you with a referral to an in-network specialist. Without a referral, the HMO may not cover the specialist's services, even if they’re in the plan’s network.

HMO plans often have a limited network of healthcare providers, which means that you may need to switch providers if your current provider is not part of the HMO's network. In almost all cases, HMO plans do not cover out-of-network care at all, except in emergency situations.

HMO plans also often require prior authorization for certain services, such as surgeries or diagnostic tests. This means that you'll need to get approval from your HMO before you can receive those services.

One of the benefits of an HMO plan is that they often have lower out-of-pocket costs than other types of plans, like PPOs. Lower costs are the advantage of having a plan with more restrictions, such as the requirement to see a PCP before seeing a specialist.

In the next section, we'll take a closer look at the pros and cons of HMO plans to help you decide if an HMO plan is right for you.

Pros and Cons of HMO Plans

Like any type of health insurance plan, HMOs have pros and cons. Here are some of the benefits and drawbacks to consider when deciding if an HMO plan is right for you:


  • Lower out-of-pocket costs than other types of plans

  • Comprehensive coverage, including preventive care services

  • Emphasis on preventive care and disease management, which may lead to less evasive and expensive treatment

  • Coordination of care by a primary care physician

  • Predictable costs and copayments


  • Limited provider networks

  • Potential need to switch providers to stay in-network

  • Requirement to obtain referrals for specialist care

  • Prior authorization requirements for certain services

  • Limited coverage for out-of-network care, if any

While an HMO plan may be a good fit for some people, it may not be the best choice for everyone, especially if you enjoy more freedom when choosing providers. In the next section, we'll discuss how to choose the right HMO plan for you.

How to Choose an HMO Plan

When choosing an HMO plan, there are several factors to consider. Here are some tips to help you find the right plan for your needs:

  1. Research provider networks. Make sure the plan you're considering has a network of providers that includes the doctors and specialists you prefer.

  2. Compare costs and benefits. Look at the plan's monthly premiums, copayments, deductibles, and other out-of-pocket costs to determine if it fits your budget.

  3. Consider personal health needs. Consider your current health status and any conditions you may have, as well as any treatments or services you anticipate needing in the future.

  4. Look at prescription drug coverage. If you take prescription drugs, make sure the plan you choose covers your medications and has a reasonable copayment.

  5. Evaluate vision and dental coverage. Consider whether the plan covers routine vision and dental care. Medicare Advantage plans often have many extra benefits not found in Traditional Medicare. Compare the extra benefits to other Medicare Advantage plans in your area.

  6. Assess travel coverage. If you travel frequently or spend part of the year in another state, make sure the plan provides coverage outside of your home state. While most plans now have national reciprocity, not all plans enjoy this benefit.

  7. Check star ratings. Look at the plan's star ratings from The Centers for Medicare and Medicaid Services (CMS) to get an idea of its overall performance.

By considering these factors and doing your research, you can find an HMO plan that meets your needs and provides the coverage you need at a price you can afford. You can also review these steps in further detail by reading our six tips on how to choose a Medicare Advantage plan in Arizona.
