The HMO — Health Maintenance Organization — is the most common plan type on Florida's ACA marketplace and the one that most Florida residents will encounter when shopping for coverage. An HMO is built around two core principles: all care flows through a primary care physician, and all care must come from in-network providers. In exchange for these restrictions, HMOs offer lower premiums and simpler cost-sharing than other plan types.

How an HMO Works

When you enroll in an HMO, your healthcare experience follows a specific structure:

Choose a primary care physician (PCP): When you enroll, you select a PCP from the plan's network. This is your main doctor for all routine and preventive care. Your PCP is also your gateway to the rest of the healthcare system within the plan.
PCP coordinates your care: If you need to see a specialist, get imaging, or receive other non-routine services, your PCP evaluates your condition and determines whether a referral is appropriate.
Get referrals for specialists: Your PCP submits a referral to an in-network specialist. Without a referral, the specialist visit may not be covered — even if the specialist is in-network.
Stay in-network: All non-emergency care must come from providers within the HMO's network. Out-of-network care is not covered, period (except for emergencies, which are always covered regardless of network status under the ACA).

Advantages of HMO Plans

Lower premiums: HMOs consistently have the lowest premiums on the Florida marketplace. The narrow network and managed care structure allow insurers to negotiate lower rates with providers.
Lower out-of-pocket costs: HMOs tend to have lower copays, coinsurance, and sometimes lower deductibles compared to PPO plans at the same metal tier.
Coordinated care: Having a PCP who knows your full medical history and coordinates all referrals can lead to better-managed, more cohesive care — especially for patients with chronic conditions.
No surprise out-of-network bills: Since all care must be in-network (except emergencies), you're unlikely to receive unexpected out-of-network charges for planned care.
Predictable costs: The simpler cost structure — copays for visits, no out-of-network tier — makes it easier to estimate your annual costs.

Disadvantages of HMO Plans

Limited provider choice: You can only see providers within the HMO's network. If your preferred doctor or hospital isn't in-network, you'll need to switch or pay out of pocket entirely.
Referral requirement: Needing a PCP referral to see a specialist adds a step — and potentially a delay — to accessing care. Some patients find this frustrating, particularly if they already know they need specialist attention.
No out-of-network coverage: If you travel frequently or split time between Florida and another state, an HMO may not cover care outside your plan's service area (except emergencies).
Network disruptions: If a key provider leaves the network mid-year, you may need to find a new doctor. Transition-of-care provisions can help, but they are temporary.

HMO Plans on the Florida ACA Marketplace

HMOs are the dominant plan type on the Florida marketplace. Major carriers offering HMO plans in Florida include:

Carrier	HMO Plan Names	Network Characteristics
Florida Blue	BlueCare HMO	Largest Florida-based network; available statewide in most counties
Ambetter	Ambetter Essential Care, Balanced Care	Narrower network; competitive premiums; strong in South and Central FL
Molina Healthcare	Molina Marketplace	Narrow network; lowest premiums in many counties; limited provider options
Oscar Health	Oscar plans (HMO-style)	Tech-forward; moderate network; telehealth integration; select metro areas

Availability varies significantly by county. Urban counties (Miami-Dade, Broward, Hillsborough, Orange) typically have the most HMO options, while rural counties may have fewer carriers and network choices.

Who HMO Plans Work Best For

Budget-conscious individuals and families who want the lowest possible premiums
People who don't travel frequently and receive most of their care near home
People comfortable with a PCP coordinating their care — particularly those with chronic conditions who benefit from centralized management
People without strong existing specialist relationships — if you don't need to see a specific out-of-network specialist, the referral process is a minor inconvenience for significant savings
Healthy individuals who primarily need preventive care and occasional routine visits

HMO vs. PPO Quick Comparison The key tradeoff: HMOs offer lower costs but less flexibility. PPOs offer more provider choice (including out-of-network coverage) but higher premiums. If keeping costs low is your top priority and your preferred providers are in-network, an HMO is typically the better value. If flexibility and specialist access without referrals matter more, consider a PPO.

How to Check If Your Doctor Is in an HMO Network

Before enrolling in any HMO plan, verify that your current doctors (or doctors you want to see) are in the plan's network:

Search the carrier's online provider directory for the specific plan name (not just the carrier)
Call the carrier's member services and confirm by provider name and NPI
Call the provider's office and ask if they accept the specific HMO plan
Check during Open Enrollment — networks can change annually

Frequently Asked Questions

What is an HMO health insurance plan?

An HMO (Health Maintenance Organization) is a type of health insurance plan that requires you to use in-network providers and select a primary care physician (PCP) who coordinates your care. You need referrals from your PCP to see specialists. HMOs do not cover out-of-network care except in emergencies.

Do I need a referral to see a specialist with an HMO?

Yes. Most HMO plans require you to get a referral from your primary care physician before seeing a specialist. Your PCP evaluates your condition and, if specialist care is needed, submits a referral to the specialist within your plan's network. Without a referral, the specialist visit may not be covered.

Are HMO plans cheaper than PPO plans?

Generally yes. HMO plans typically have lower monthly premiums than PPO plans because they use narrower networks and the referral system helps control utilization. On the Florida ACA marketplace, HMO plans are often the most affordable option, especially at the Bronze and Silver tiers.

Most Florida ACA marketplace carriers offer HMO-style plans, including Florida Blue (BlueCare HMO), Ambetter, Molina Healthcare, and others. HMOs are the most common plan type on the Florida marketplace. Availability varies by county — check healthcare.gov for plans available in your area.
