How To Switch From Hmo To Ppo What To Expect? Key Facts

Switching from an HMO to a PPO means you are moving from a plan that requires you to pick a primary care doctor and get referrals to see specialists, to a plan that lets you see any doctor or specialist without a referral. The key fact is that PPOs offer more flexibility and a wider choice of doctors, but they usually come with higher monthly premiums and out-of-pocket costs. You can only switch during the annual Open Enrollment Period or if you have a qualifying life event, like getting married or losing other coverage.

What Is the Main Difference Between an HMO and a PPO?

An HMO, or Health Maintenance Organization, works like a network. You choose one primary care doctor from a list of approved providers. That doctor manages your care and must write a referral before you can see a specialist. If you go outside the network for non-emergency care, you pay the full cost yourself. The trade-off is that HMOs typically have lower monthly premiums and lower copays.

A PPO, or Preferred Provider Organization, gives you more freedom. You do not need a primary care doctor to manage your care. You can make an appointment with a specialist directly. You can also see doctors outside the network, though you will pay more for it. The trade-off is that PPOs have higher monthly premiums and you usually have a deductible to meet before full coverage kicks in. According to the Kaiser Family Foundation, average annual premiums for PPOs are often several hundred dollars higher than for HMOs.

When Can You Switch From HMO to PPO?

You cannot switch plans anytime you want. The law sets specific windows. The main one is Open Enrollment Period, which runs from November 1 to January 15 in most states. Any plan you pick during this time starts on January 1. If you miss this window, you typically wait a full year.

There are exceptions called qualifying life events. These include losing job-based coverage, getting married or divorced, having a baby, or moving to a new area that your current plan does not cover. If one of these happens, you get a Special Enrollment Period. You usually have 60 days from the event to choose a new plan. The federal Health Insurance Marketplace website clearly lists all qualifying events.

How To Switch From HMO to PPO: What To Expect Step by Step

First, check when you can switch. Look at your current plan’s end date and the Open Enrollment dates for your state. If you have a qualifying life event, gather the documentation — a marriage certificate, a birth certificate, or a letter from your employer proving loss of coverage.

Second, shop for plans. Do not just look at the monthly premium. Look at the deductible, the copay for a specialist visit, and the out-of-pocket maximum. A PPO with a low premium often has a high deductible. Use the Marketplace website or your state’s insurance exchange to compare plans side by side. The Centers for Medicare & Medicaid Services requires all plans to show a standard Summary of Benefits and Coverage, which makes comparison easier.

Third, check your doctors. Call your primary care doctor and any specialists you see. Ask if they are in-network for the PPO plan you are considering. Many PPO networks are smaller than HMO networks in some regions. A 2023 study in Health Affairs found that narrow networks are becoming more common in PPO plans, so do not assume every doctor will be covered.

Fourth, enroll. You can do this online through the Marketplace, by phone, or with a licensed insurance broker. After enrollment, you will get a new insurance card and a welcome packet. Your new coverage starts on the date specified in the plan, usually the first of the month after enrollment.

What Are the Costs You Should Expect?

PPOs generally cost more per month. According to data from the Kaiser Family Foundation, the average monthly premium for a PPO in 2024 was about $620 for an individual, compared to roughly $480 for an HMO. These numbers vary by state and by plan tier.

You will also face a deductible. This is the amount you pay out of pocket before the insurance company starts paying its share. For a PPO, the average individual deductible is around $1,500 to $2,500. Some plans have separate deductibles for in-network and out-of-network care. After you meet the deductible, you usually pay a coinsurance, which is a percentage of the bill — often 20% for in-network care and 40% for out-of-network care.

There is also an out-of-pocket maximum. This is the most you will pay in a year for covered services. For 2024, the federal limit is $9,450 for an individual plan. Once you hit this number, the plan pays 100% for covered care. This cap protects you from catastrophic costs, but it is higher than most HMO out-of-pocket maximums.

Comparison: HMO vs. PPO at a Glance

What Happens to Your Current Care During the Switch?

When you switch from an HMO to a PPO, your old plan ends on the date specified. Any care you received before that date is covered by the old plan. Any care after that date is covered by the new PPO. This means you might have to change doctors if your current doctor is not in the new PPO network.

If you are in the middle of a treatment plan — like physical therapy or a series of injections — check with your new insurance first. Some PPO plans require prior authorization for certain treatments, even if the doctor is in-network. A 2022 report from the American Medical Association found that prior authorization rates are rising across all plan types, including PPOs. Do not assume your new plan will automatically cover ongoing care. Call the insurance company and ask about your specific situation.

If you take prescription medications, check the new plan’s formulary. This is the list of drugs the plan covers. A drug covered by your HMO might not be covered by your PPO, or it might be in a higher tier with a larger copay. You can ask your doctor for a formulary exception if the drug is medically necessary, but this takes time and paperwork.

Common Misconceptions About Switching to a PPO

One common myth is that a PPO always covers every doctor. This is false. PPO networks can be just as narrow as HMO networks, especially in rural areas. Always verify network participation before enrolling.

Another myth is that you can switch plans whenever you want. As covered above, you cannot. The only times are Open Enrollment or a qualifying life event. Do not cancel your HMO expecting to join a PPO later in the year — you could end up uninsured.

Some people also believe that a PPO will save them money because they can see any doctor. This is not always true. The higher premiums and deductibles can outweigh the savings from lower copays. A 2021 analysis from the Commonwealth Fund found that people with PPOs were more likely to report problems paying medical bills than people with HMOs, largely because of higher out-of-pocket costs.

What to Avoid When Switching

Avoid choosing a PPO based only on the monthly premium. Look at the total cost picture, including deductible, copays, and out-of-pocket maximum. A low premium can hide a high deductible that leaves you paying thousands before coverage kicks in.

Avoid assuming that out-of-network coverage means you can go anywhere and pay a little extra. Out-of-network care on a PPO often means you pay a much higher coinsurance — sometimes 40% or 50% of the bill. You also may be balance-billed, meaning the doctor charges you the difference between their fee and what the insurance pays. This can lead to unexpected, large bills.

Avoid switching without checking your prescription drug coverage. A PPO might cover your daily medication at a lower tier, or it might not cover it at all. A 2023 survey from the Kaiser Family Foundation found that 1 in 4 people with a PPO reported a problem getting a prescription filled because of cost or coverage limits. Check the formulary before you enroll.
