Pricing off Medicare: the multiple and its blind spots
Summary
Pricing fees as a multiple of Medicare — for example, setting a self-pay or target rate at some percentage above the Medicare-allowed amount — works because Medicare's rate is public, code-specific, and updated on a known schedule. It breaks down in three places: the rate isn't one number but varies by locality and by facility versus non-facility setting, and a Medicare-participating clinician's actual received rate can move after MIPS payment adjustments apply, so the raw fee-schedule figure isn't always what lands in the bank.

Why Medicare is the common anchor
Medicare is the anchor most solo practices reach for because it's the one rate that's actually public: CMS's fee schedule sets a code-specific, locality-adjusted payment amount for clinician services, republished every year through formal rulemaking 1Ref 1Centers for Medicare & Medicaid Services (2026).Physician Fee Schedule.That the Medicare Physician Fee Schedule is published and updated annually through formal rulemaking, which is why a multiple calculated off it needs to be refreshed., and any practice can look up the exact figure for any CPT or HCPCS code through the MPFS lookup tool CMS publishes for that purpose 2Ref 2Centers for Medicare & Medicaid Services (2026).Physician Fee Schedule Search.That the public lookup tool returns a locality-adjusted payment amount per code, meaning the Medicare rate for a code is not one national figure.. No commercial payer publishes anything comparable without being asked.
The method itself is simple — pick a target percentage above the Medicare rate (150%, 200%, whatever the practice decides its self-pay or negotiation target is), and multiply. The problem isn't the arithmetic; it's that "the Medicare rate" for a given code isn't actually one fixed number.
What actually sets the number you're multiplying
The Medicare rate behind the multiple isn't a single negotiated figure; it's the product of a formula — relative value units for the work, the practice expense, and malpractice risk behind a code, adjusted for geography, multiplied by a single conversion factor CMS sets and can revise through the same annual rulemaking that updates the rest of the schedule 1Ref 1Centers for Medicare & Medicaid Services (2026).Physician Fee Schedule.That the Medicare Physician Fee Schedule is published and updated annually through formal rulemaking, which is why a multiple calculated off it needs to be refreshed.. Any one of those pieces moving between one year and the next moves the base number a multiple is built on, even if the target percentage itself never changes.
That's a different kind of drift than a locality or setting mismatch — it's not that the wrong number was pulled, it's that the right number from last year is no longer the right number this year. A multiple recalculated once and then left alone quietly loses accuracy every rulemaking cycle it isn't refreshed against.
Blind spot: the rate isn't one number
The figure that shows up in the fee schedule lookup already reflects a locality adjustment — GPCIs and localities mean the same code pays a different amount in different parts of the country, sometimes by a meaningful margin, because of how CMS weights each area's practice costs 2Ref 2Centers for Medicare & Medicaid Services (2026).Physician Fee Schedule Search.That the public lookup tool returns a locality-adjusted payment amount per code, meaning the Medicare rate for a code is not one national figure.. A multiple calculated off one region's rate and applied everywhere a practice operates, or copied from a colleague in a different state, is anchored to the wrong base before the multiplication even starts.
Pull the locality-specific figure for the ZIP code the service was actually rendered in, not a national average or a remembered number from a different year.
Blind spot: facility versus non-facility
The same code can carry two different Medicare rates depending on where the service happened, because the place-of-service code on the claim determines whether facility or non-facility pricing applies 3Ref 3Centers for Medicare & Medicaid Services (2026).Place of Service Code Set.That the place-of-service code determines whether facility or non-facility pricing applies, meaning the same code can carry two different Medicare rates.. A multiple built off the non-facility rate and then used to price a service delivered in a facility setting — or the reverse — compounds a pricing error every time that code is billed in the other setting.
A practice that works in more than one setting needs the multiple applied per place of service, not a single number carried across both.
Blind spot: the multiple isn't the whole story for Medicare-participating clinicians
For a clinician who actually bills Medicare, the published fee schedule amount isn't necessarily the final number that lands. MIPS — the program that scores eligible clinicians on quality, cost, and related categories — adjusts Medicare Part B payment up or down from that base rate, though clinicians under the program's low-volume threshold are excluded from it entirely 4Ref 4Centers for Medicare & Medicaid Services (2026).MIPS Overview.That MIPS adjusts a Medicare-participating clinician's Part B payment up or down from the base fee-schedule rate, and that low-volume-threshold clinicians are excluded.. A multiple built purely off the raw fee-schedule figure ignores that a Medicare-participating practice's real received rate may already differ from the number it's anchoring against.
This blind spot doesn't affect a purely self-pay or non-participating practice using Medicare only as a reference point — it matters specifically for a clinician whose own Medicare payments are subject to the adjustment.
What commercial payers actually do with their own rates
Some commercial contracts are literally written as a percentage of the current Medicare fee schedule, which makes the multiple method directly useful for reading that contract. Others set a flat dollar rate with no reference to Medicare at all, in which case a Medicare-based multiple is only a planning tool for comparison, not a prediction of what that specific payer will actually pay — your contract, not the general pattern, controls the real number.
Check which kind of contract you're actually looking at before assuming a Medicare multiple predicts a commercial payer's behavior.
Reading the compensation section of the actual signed agreement, rather than relying on what a credentialing representative described verbally at the time of signing, is the only reliable way to know which category a specific payer falls into — a contract can also mix the two approaches, indexing some code families to Medicare while pricing others as flat, independently set rates.
Using the multiple to set a self-pay rate
For services with no insurance rate to anchor against at all, a Medicare multiple gives a defensible, explainable starting point — a number a patient or a payer reviewing the charge can trace back to a public source, rather than one that looks arbitrary. Pick the locality- and setting-correct Medicare figure first, apply the target percentage, and document the method so the same logic reproduces the same price consistently across your fee schedule rather than being decided code by code from memory.
What has no Medicare code to price against
Some services a solo practice bills have no real Medicare analogue at all — a cosmetic add-on, a wellness offering Medicare doesn't cover, or a service coded with a specialty-specific code Medicare rarely pays. For those, the multiple method runs out of a base to multiply, and the practice is setting a market rate directly rather than deriving one.
A common convention when that happens: price the uncovered service against a comparable code's Medicare rate where one loosely exists, or against what local self-pay patients and cash-pay competitors are actually charging, and document the reasoning the same way as any other line on the fee schedule — so the number is defensible even without a public anchor behind it.
