What Is a Health Maintenance Organization (HMO)?

If you're shopping for health insurance, you'll encounter various providers with distinct features. One common option is the health maintenance organization (HMO), which delivers coverage via a network of physicians.

There are notable differences between HMO plans and the more prevalent preferred provider organization (PPO) plans. In an HMO, your primary care physician refers you to specialists, and you must stick to the network for coverage. HMOs generally feature lower premiums than PPOs.

To sum up the essentials: An HMO is a network providing health insurance for a monthly or annual fee, limiting coverage to specific providers. These contracts enable lower premiums but impose restrictions on members. You must start with services from your designated primary care physician (PCP). Alternatives include PPOs and point-of-service (POS) plans.

How a Health Maintenance Organization (HMO) Works

HMOs offer health insurance for a monthly or annual fee, typically restricting coverage to care from in-network doctors, hospitals, and providers, except in emergencies or out-of-area urgent care.

Providers contract at discounted rates due to guaranteed patient volume, allowing HMOs to cut costs and provide lower premiums than other plans. This setup can limit your care options as an HMO member.

When choosing an HMO, consider the premium costs, out-of-pocket expenses, your needs for specialized care, and whether having your own PCP matters to you.

An HMO builds its network by contracting with PCPs, facilities, and specialists to offer basic and supplemental services. Beyond savings, these contracts ensure consistent care standards. The referral system between PCPs and specialists promotes integrated care focused on prevention and wellness.

The modern HMO originated from the Health Maintenance Organization Act of 1973, defining HMOs as entities providing health services for fixed premiums under a community rating system.

Rules for HMO Subscribers

As an HMO subscriber, you pay a monthly or annual premium for access to in-network services. You're generally limited to this network, but emergencies and certain urgent treatments like dialysis are covered out-of-network.

You might need to live or work in the plan's area for eligibility. For urgent care outside the area, HMOs often cover out-of-network providers if treatment is needed within 24 to 48 hours. Nonemergency out-of-network care, including routine urgent care, requires you to pay fully out of pocket.

HMOs feature low or no deductibles, charging co-pays for visits, tests, or prescriptions instead.

Role of the Primary Care Physician (PCP)

Under an HMO, you select a PCP from the network as your first contact for health issues. You can't see a specialist without a PCP referral.

Some services, like annual mammograms for women over 40, don't require referrals. Specialists are in-network, so services are covered after co-pays. If your PCP leaves, you're notified to choose another from the network.

HMO Regulation

Health insurance regulation, including HMOs, has historically been state-based, but the 2010 Patient Protection and Affordable Care Act (PPACA) increased federal involvement.

The McCarran-Ferguson Act of 1945 keeps states primary, preventing federal override unless specified. Laws like the 1973 HMO Act and 1974 ERISA bring some federal oversight.

The 2010 Dodd-Frank Act created the Federal Insurance Office, expanding federal insurance regulation, though not directly for health insurance. The ACA Marketplace offers various plans, including HMOs, for individuals and businesses.

HMO vs. Preferred Provider Organization (PPO)

PPOs are the most common employer-sponsored plans, covering 47% of workers per KFF data, compared to 13% in HMOs.

PPOs let you use any in-network provider freely, with out-of-network options at higher costs. HMOs mandate in-network care only. PPOs have deductibles; HMOs usually don't.

Both allow specialists, but HMOs require PCP referrals. PPOs offer flexibility but higher premiums. Over time, PPO advantages have diminished as networks shrink.

HMO vs. Point-of-Service (POS)

A POS plan requires an in-network PCP and referrals like an HMO, but covers out-of-network services at higher costs like a PPO.

POS may reduce out-of-network costs with referrals. Premiums are between HMO and PPO levels. POS has low in-network co-pays and no deductibles for in-network care, but high out-of-network deductibles.

POS suits frequent travelers with out-of-network options. If you don't travel much, an HMO's lower costs might be better.

Advantages and Disadvantages of HMOs

Weigh HMO pros and cons before deciding, as with any plan.

Pros

  • Lower out-of-pocket costs: Fixed low premiums, minimal deductibles, and lower co-pays simplify billing.
  • Primary care physician directing treatment: Your PCP manages care and refers specialists.
  • Higher quality of care: Emphasis on prevention encourages early treatment.

Cons

  • Must use network professionals: You're limited to in-network doctors for coverage.
  • No specialist visits without referral: PCP approval is needed, or you pay full costs.
  • Emergencies must meet conditions: Strict definitions apply for coverage.
