Comparing Health Insurance: HMOs vs. PPOs vs. High Deductible Plans


Selecting the right health insurance plan is an important decision that balances cost, coverage, and convenience. The three main types of plans each have their pros and cons – Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), and High Deductible Health Plans (HDHPs) paired with Health Savings Accounts (HSAs). This article will compare the key features of HMO vs. PPO vs. HDHP plans to help consumers choose the best option.

How HMOs Work

HMOs offer lower premiums in exchange for restricted provider choice and healthcare management:

Limited Provider Network

Members must pick a primary care physician (PCP) within the HMO’s network who coordinates care and referrals. Out-of-network providers are generally not covered except emergencies.

Primary Care Focus

PCP referrals are required for specialists. No referrals means no coverage. This acts as care gatekeeper.


Many services like tests, procedures, surgeries require pre-approval from the HMO even if your PCP recommends them.

No Out-of-Pocket Expenses

Once copays are met, HMOs cover all in-network care. But copays still apply for drugs and services.


HMOs offer lower monthly premiums on average compared to PPO plans.

How PPOs Work

PPOs offer greater choice of providers with less oversight at a higher cost:

Nationwide Provider Network

Members are not restricted to select providers. Visits to any doctor or hospital in the PPO network is covered nationwide.

No Referrals Needed

Members can directly access specialists without referrals from a PCP, which provides greater flexibility.

Out-of-Network Coverage

PPOs pay a portion of the cost for visiting providers outside of their network, unlike HMOs. But out-of-network providers bill you the balance amount above what the PPO pays.

No Pre-Authorization Required

No approval needed from insurer for medical services if network providers are used.


Average monthly premiums for PPO plans are higher than comparable HMO plans.

How High Deductible Health Plans Work

HDHPs have higher deductibles but lower premiums and can be paired with tax-advantaged HSAs:

High Deductibles

Deductibles typically range from $1500 to $7000 annually per person before coverage kicks in. Families have higher deductibles.


Can be paired with HSAs that allow tax-deductible contributions to pay the high deductibles and other medical expenses. Unused HSA balances carry over.

Low Premiums

HDHPs offer lower monthly premiums – 25% to 40% lower on average than traditional plans since deductibles absorb costs upfront.

Unlimited Provider Choice

Members have freedom to access any healthcare providers without restrictions.

Post-Deductible Coverage

After deductible is met, coverage functions like a traditional plan and pays a percentage of additional costs based on coinsurance.

Choosing the Right Plan

Factors to consider when selecting an insurance plan:

Provider Network

Do the doctors you want to see participate in the plan’s network? Check provider directories.


Weigh monthly premiums vs. annual deductibles and copays based on expected healthcare usage and budget.

Health Conditions

Account for any chronic conditions and specialty care needed when considering networks and costs.

Tax Savings

The HSA component of HDHPs provides unique tax advantages that can offset higher deductibles for some.

Prescription Needs

Compare drug formularies. HMOs and HDHPs have more restrictions.

Travel Frequency

Those traveling often will benefit from PPO nationwide networks. HMOs have limited coverage outside service areas.

Life Stage

Younger healthy individuals may opt for lower cost HDHPs, while families may prefer HMOs or PPOs despite higher premiums.


There are trade-offs between affordability, flexibility, and coverage with HMO, PPO and HDHP health plans. Examining expected healthcare needs, finances, provider preferences, and tax considerations can help consumers identify the optimal health insurance plan type for their situation. Most importantly, reading plans details carefully rather than simply comparing monthly costs provides the full picture.
