Reference-Based Pricing, Explained for Self-Funded Employers

The Question Network Discounts Can't Answer

Ask your carrier what a knee MRI costs under your plan and you'll get a discount: "We have a 55% discount off billed charges at that facility." Ask what the facility bills, and the answer is whatever the facility decided to bill. A 55% discount off a $4,000 charge is more expensive than no discount off a $1,500 charge — and hospital chargemasters are set with exactly that math in mind.

That's the problem reference-based pricing exists to solve. Instead of negotiating a percentage off an arbitrary number, RBP prices each claim from a benchmark that is published, audited, and the same for everyone: what Medicare pays for that service, in that setting, in that geography.

How RBP Actually Prices a Claim

Medicare's fee schedules assign a price to essentially every billable service — physician work, facility costs, geography adjustments, all of it published by CMS and updated quarterly. An RBP plan takes that number and pays a defined multiple of it. The multiple varies by plan design and service type; paying somewhere between 120% and 200% of Medicare is typical across the industry, with facility claims usually anchored higher than Medicare but far below chargemaster rates.

Three things follow from that design:

• The price is defensible. When a plan pays 150% of what Medicare pays, it isn't lowballing — it's paying half again more than the largest payer in the country, from the same public data the hospital's own reimbursement team uses.
• There is no network. Because the price comes from the benchmark rather than a contract, members can see any provider. No narrow-network surprises, no out-of-network penalty tier.
• The savings are structural. Hospital billed charges commonly run 300–600% of Medicare. Even generous RBP multiples remove a large share of that markup without touching how much care members use.

The Balance-Billing Question (Ask It First)

RBP's honest weak point: a provider that wants more than the reference-based payment can bill the member for the difference. Any RBP administrator that doesn't lead with how it handles balance bills is hiding the most important part of the design.

A properly run RBP program treats member protection as part of the plan, not an add-on:

• Advocacy on every balance bill. The member hands the bill over and advocates engage the provider directly — most balance bills resolve through negotiation once the provider understands the plan's payment basis.
• Defense when it escalates. For the minority of disputes that harden, the program provides legal defense of the member. The member is coached from day one: don't ignore the bill, don't pay it — send it in.
• Provider engagement before care. Good programs work provider relations proactively — scheduled procedures get pre-service outreach so the facility knows how payment works before the member is on the table.

When you evaluate an RBP offering, ask: who employs the advocates, what's the average resolution time on a balance bill, and does the member ever pay out of pocket while a dispute is open?

What RBP Does to Stop-Loss

Stop-loss underwriters price to expected claims. A plan that pays a disciplined multiple of Medicare has lower and more predictable large-claim exposure than a plan paying discounted chargemaster rates, and carriers commonly quote RBP plans meaningfully lower on specific premiums. For employers whose stop-loss renewal has been climbing double digits, the RBP conversation and the stop-loss conversation are the same conversation.

When RBP Is the Wrong Fit

RBP is a plan design, not a religion. It fits badly when:

• Your workforce is concentrated around a dominant health system that refuses RBP payment and has no meaningful competitor. Advocacy works, but daily friction with the only hospital in town wears on employees.
• Leadership won't invest in member communication. RBP shifts how members experience billing. Without a real education effort at enrollment — what a balance bill is, what to do with it — confusion erodes trust in the benefit.
• You want zero noise more than you want savings. RBP produces some provider pushback. A well-run program absorbs it, but "absorbs" is not "eliminates."

An administrator that pitches RBP to every group regardless of geography and culture is selling a product, not designing a plan. Hybrid approaches — RBP on facility claims with a physician network, or RBP as an option alongside a traditional network design — exist precisely because one size doesn't fit all.

Questions to Ask Any RBP Administrator

1. What benchmark and what multiple, by service type — and will you show the math on a real claim?
2. Who handles balance bills, what does resolution look like, and what does the member experience during it?
3. What percentage of claims generate provider disputes, and how many escalate past negotiation?
4. How do you handle scheduled, high-dollar procedures before the member arrives?
5. How do stop-loss carriers you work with price the design?
6. What does member education look like at enrollment and at first use?

How SmartTPA Runs RBP

We offer reference-based pricing as a plan design option, delivered with an established RBP partner whose entire business is benchmark repricing, provider engagement, and member advocacy — including balance-bill defense. Claims price from published Medicare-anchored benchmarks; members keep full provider choice; and our platform gives the employer claim-level visibility into what was billed, what the benchmark said, and what was paid.

We'll also tell you if RBP is the wrong fit for your group — geography and workforce matter, and we model traditional network designs alongside RBP so you can compare real numbers, not philosophies. If you want to see what your last plan year would have looked like under a reference-based design, request a proposal and we'll run the comparison.
