What it means
A preferred provider organisation, or PPO, is built around a contract between the insurer and a group of healthcare providers. The providers accept lower negotiated fees in return for a steady flow of patients.
Members who use those providers pay less out of pocket than if they go elsewhere. Unlike plans that require a member to choose a single primary doctor and get referrals, a PPO generally lets members see specialists directly.
Out-of-network care is usually still covered, but at a lower percentage, and the member may also be billed for the gap between the provider's charge and the amount the insurer recognises. That flexibility is the main reason PPOs tend to carry higher premiums than more restricted plans.
For a business, the choice of plan is a major cost and recruitment decision. Employers typically pay a large share of each employee's premium, so the plan design affects the benefits line in the budget and the competitiveness of job offers.
Finance teams compare premiums, deductibles (the amount a member pays before the insurer contributes), coinsurance (the percentage split of costs after the deductible) and annual out-of-pocket limits. The real cost to a member depends on how the plan's pieces interact.
A low premium with a high deductible can leave a family with large bills after a hospital stay, while a higher premium with a low deductible gives more predictable costs. Looking at total expected spend across premiums and likely claims is more informative than looking at premiums alone.
One nuance is that networks change. A provider may leave the network between plan years, and members who assumed their doctor was covered can face higher bills.
HR and finance teams should remind employees to confirm network status before planned treatment. Employers can also run a PPO alongside a health savings or reimbursement arrangement.
This lets staff set money aside to cover deductibles, which softens the impact of a large bill and makes the plan easier to sell internally.
In practice
Real-world examples.
Example
A marketing agency with 60 employees offers a PPO so staff can see specialists without referrals. The finance manager budgets $620 per employee per month as the employer contribution. The plan is popular and helps the agency compete for new hires.
Example
A travelling sales director lives in two cities and wants coverage in both. A PPO with a national network lets him use in-network doctors in either place. He avoids paying out-of-network rates on routine care.
Example
A manufacturer reviews its plans at renewal and finds the PPO premium has risen 9%. The finance team models the extra cost against moving to a narrower network plan, then keeps the PPO but raises the employee deductible to hold the budget steady.
Formula
Calculation
Member cost = deductible + coinsurance rate x (allowed charge - deductible), capped at the out-of-pocket limit
Suppose a member has a $1,000 deductible and 20% coinsurance, and has an in-network procedure with an allowed charge of $5,000. After the deductible, the remaining amount is 5,000 - 1,000 = $4,000. Coinsurance is 20% x 4,000 = $800. The member pays 1,000 + 800 = $1,800 and the insurer pays the remaining $3,200. The out-of-pocket limit would only matter if the member's total for the year exceeded it.Case study
Seen in the real world.
Cedarpoint Engineering is an illustrative, fictional firm with 120 employees. The owner wanted to cut benefit costs and was considering a plan with a smaller network and lower premiums. The finance lead surveyed staff and found many had long-standing relationships with specialists who were not in the smaller network.
She built a comparison showing the PPO would cost about $90,000 more per year in premiums, but that the cheaper plan would likely push staff towards out-of-network bills and push some to leave. Replacing even three skilled engineers would cost more than the premium difference. The owner kept the PPO, and the illustrative lesson was that the cheapest premium is not always the cheapest decision.
A year later the finance lead reported the result to the owner. Staff turnover in the engineering team had stayed low, and the company had avoided a costly recruitment drive. The illustrative result was that the plan paid for part of itself through retention.
Watch out
Common mistakes.
- Comparing plans on premium alone, without adding the deductible, coinsurance and out-of-pocket limit.
- Assuming a doctor stays in the network all year, when providers can join or leave at any time.
- Believing out-of-network care is not covered at all, when a PPO normally covers some of it at a lower rate.
Questions
People also ask.
How is a PPO different from an HMO?
A PPO lets members see specialists and out-of-network providers without a referral, whereas an HMO typically restricts members to its network and requires referrals.
Why are PPO premiums often higher?
The flexibility to choose any provider and to skip referrals raises the expected cost of claims, and the premium reflects it.
What is an out-of-pocket maximum?
It is the most a member can pay in a plan year for covered in-network care, after which the insurer pays the full allowed amount.
