What Employers Actually Pay for Imaging: Self-Funded Plan Edition

If your company self-funds its health plan, every MRI your employees get is paid with plan money, and the same scan can settle at wildly different prices depending on where it happens. This page is for benefits managers, CFOs and brokers: the documented size of the spread, the two contracting models that attack it, and what to ask your TPA on Monday.

Why imaging is a cost hotspot: the spread, documented

Advanced imaging combines three things a plan sponsor should care about: high volume, a genuinely commoditised product (the scan is defined by CPT code and magnet strength, not by the building it happens in), and a hospital-vs-freestanding price gap larger than almost any other outpatient service. We have verified that gap in one city end to end. The figures below are hospital cash list prices for the same brain MRI, CPT 70551, parsed from CMS-mandated hospital price transparency filings, as published on our Houston MRI cost page (retrieved 3 August 2026):

Your plan does not pay list prices; it pays negotiated rates. But negotiated rates are anchored to the facility's pricing posture, and the pattern in every transparency dataset is the same: hospital outpatient departments settle several times above freestanding centres for the same code. A plan whose members default to hospital campuses for scheduled outpatient MRI is paying that difference on every scan, silently, through claims.

The employee sees it too. Until their deductible is met, the member pays the negotiated rate out of pocket, so hospital-default imaging inflates both plan spend and employee cost-sharing; the member-side mechanics are on our MRI cost with insurance page.

Reference-based pricing and direct imaging contracts

Reference-based pricing (RBP) replaces network-negotiated rates with a payment rule: the plan sets a fixed limit on what it will pay for a service, most commonly a percentage or multiplier of the Medicare rate. SHRM's explainer (retrieved 3 August 2026) describes employers setting “a fixed limit on the amount a plan will pay for certain health care services”, with the limit “often based on a percentage or multiplier of what Medicare would pay the provider”, and illustrates with a procedure paid at 200 percent of Medicare against a much higher billed charge.

The honest trade-off, flagged in the same SHRM piece, is balance billing: a provider that never agreed to the reference price can pursue the patient for the difference between the plan's payment and its charge. RBP programmes therefore live or die on member support, provider negotiation and dispute handling, not on the pricing formula. Imaging is nonetheless one of RBP's natural fits: the service is scheduled (so members can be steered before the fact), the Medicare benchmark is unambiguous per CPT code, and the transparency-file spread means egregious claims are easy to document.

Direct imaging contracts are the narrower version of the same idea: rather than repricing all claims, the plan (or its TPA) contracts directly with specific freestanding imaging providers at agreed rates, then steers members there through plan design, lower or waived cost-sharing for using the contracted facilities. No repricing fight, no balance-billing exposure at the contracted sites; the constraint is geographic coverage and member adoption.

Bundled cash-pay imaging networks

A third route skips claims entirely: bundled cash-pay imaging networks quote one all-in price per imaging order, facility fee and radiologist read included, paid upfront with no bill afterwards. For a self-funded plan they function as an imaging carve-out: the plan or member sends the physician's order, the network quotes the bundled price at partner facilities near the member, and the scan is settled at that price.

We publish no dollar figure for what employers save through bundled networks, because no reliable public number exists; quotes are per order and per market. The verifiable baseline is the published cash market itself: freestanding programmes publishing $263 to $280 for an MRI in a metro where hospital claims settle in the four figures is the arbitrage a carve-out captures.

The do-it-Monday checklist

1. Pull imaging claims by CPT code and place of service

   Ask your TPA for 24 months of claims on the high-volume imaging codes (70551/70553, 72148/72158, 73721, plus CT equivalents) with allowed amounts and place of service. This is your data; a self-funded sponsor is entitled to it.

2. Measure your own hospital-vs-freestanding spread

   For each code, compare median allowed amount at hospital outpatient departments against freestanding centres. The gap, multiplied by your hospital-setting volume, is the annual addressable number that funds everything else on this list.

3. Check what steering, if any, your plan already does

   Does the plan design make a freestanding scan cheaper for the member than a hospital scan? If cost-sharing is identical in both settings, your plan is paying members nothing to choose the cheaper site, and they won't.

4. Ask your TPA about imaging carve-outs and RBP for imaging

   Specific questions: can the plan contract directly with freestanding imaging providers or a bundled network? Can imaging be repriced against a Medicare benchmark, and who handles balance-billing support if so? What have they implemented for other clients?

5. Sanity-check outliers against public transparency files

   Hospitals must publish machine-readable price files under the federal transparency rule. If a claim settled far above the hospital's own published negotiated rate for that code, ask the TPA why.
