A cardiologist gets an email inviting her to a paid consultation about a device. Forty-five minutes on the phone with an investor who wants to understand implant trends.
She has no idea what to charge. So she does what essentially every physician does: she asks a colleague, who guesses, and she names a number.
She says $400. The call happens. It is professional and useful and she is paid promptly.
What she does not know is that the firm arranging the call billed its client somewhere between $1,000 and $1,400 for that same hour.
She is not being defrauded. This is how expert networks work, it is disclosed in the industry's own published materials, and the intermediary does real work arranging, screening, and compliance-checking the engagement.
The point is narrower and more interesting than outrage about margins.
She had no way to know. And that is true across every channel in which a clinician sells professional judgment.
Six markets, one brain, a twenty-fold spread
A physician's expertise is sold into at least six distinct markets, and the prices differ by more than an order of magnitude for the same hour of the same person.
Micro-surveys. Physician survey work pays roughly $1 to $6 per minute of survey time, according to physician-facing community resources that track it. At the low end, that is $60 an hour for work that requires a medical degree.
Expert network calls. Networks pay their experts roughly $200 to $500 per hour, while clients typically pay $1,000 to $1,400 for the same hour, with only high-demand healthcare key opinion leaders and C-suite experts exceeding $1,000 on the expert side.
Expert witness work. Community-maintained databases indicate most physicians set rates between $300 and $800 per hour, with outliers in both directions.
Advisory boards. Frequently compensated in equity rather than cash, at grants commonly in the 0.1 to 0.5 percent range vesting over two years, with no published cash equivalent anywhere.
Speaking and teaching. Honoraria set by convention, by institution, and by whatever the organizer offered last year.
Chart review and utilization work. Priced per case or per hour depending on the buyer, with essentially no public benchmark.
Set those side by side. The bottom of a clinician's own price distribution is around $1 a minute. The top, for the same person selling the same underlying judgment, can be $800 an hour or more.
That is a 10 to 20 times spread, and it is not explained by expertise. It is explained by which channel someone happened to find.
Price information is destroyed at every hop
This is not an accident of an immature market. The structure actively destroys the information.
Expert networks tell the expert their rate and never the client's. From inside the transaction, the physician sees one number. The spread is invisible by design, and there is no reason for the intermediary to reveal it.
Survey panels quote per-survey amounts that obscure the hourly rate. "$45 for this survey" does not tell you whether that is $90 an hour or $180 an hour until you have done it, and the length estimate is frequently optimistic.
Advisory equity has no published cash equivalent. A 0.25 percent grant in a seed-stage company is worth an amount that nobody, including the company, can state honestly.
And the one public database that might have served as a rate card does not. CMS Open Payments records what industry paid, after the fact, comprehensively. It records no hours, no scope, and no deliverable. A $12,000 payment could be forty hours of substantive work or a single speaking engagement. As a price signal it is close to useless.
Meanwhile, professional norms actively discourage the obvious fix. Physicians do not, as a rule, compare fees with each other. There is a residual sense that discussing what you charge is unseemly, which is a norm that costs the profession an enormous amount of money and benefits every buyer.
The result: nobody records what anyone was actually paid, so the next clinician starts from zero, and the least informed sellers subsidize the most sophisticated buyers.
Who this hurts most
The distribution of harm is predictable, and it lands on exactly the people you would expect.
Early-career physicians take $1-a-minute survey work because it is the only channel that finds them. Survey panels market aggressively to new physicians precisely because they are reachable and have no benchmark.
Retired and semi-retired clinicians have the deepest expertise and the weakest commercial networks. Their institutional email has stopped working, their affiliation has lapsed, and the recruitment emails have stopped arriving. They are frequently the most qualified and least findable participants in the market.
Nurses, pharmacists, and physician assistants face all of the same opacity with even less published benchmark data, in markets that are smaller and more relationship-dependent.
Community clinicians without academic affiliations are underpriced relative to academics with equivalent or lesser operational knowledge, because prestige is a legible signal and operational depth is not.
And, less obviously, buyers are harmed too. A buyer who cannot distinguish price from quality is paying a premium for a proxy. Firms routinely pay top rates for the most published expert and receive advice that is less useful than what a high-volume community operator would have given them at a third of the cost.
A market with no price transparency misallocates in both directions.
Why this matters more now than it did five years ago
Three developments have converged.
The side-income economy went mainstream. Clinicians are hedging against employment instability, consolidation, and burnout. What was once a niche activity for a small number of academics is now a routine part of professional income for a broad population, and the participants are largely new to it.
The expert market is growing quickly. The expert network industry reached roughly $3 billion in 2025, with client firm counts up about 150 percent since 2022. The B2B and healthcare survey sampling industry reached about $1.1 billion in 2023. Demand for clinician judgment is rising sharply.
And AI has changed what is scarce. As machine systems commoditize generic knowledge work, the premium shifts to verified, specific, accountable human judgment on hard questions. Clinician expertise is appreciating as an asset at precisely the moment its owners have the least idea what it is worth.
The reframe: this is not a disclosure problem
Every conversation about physicians and money in the last decade has been about disclosure. Open Payments exists. Sunshine rules exist. Conflict-of-interest policies exist.
That entire apparatus answers the question "who paid this physician?" It is a reasonable question and it is comprehensively answered: a JAMA analysis found 57.1 percent of US physicians received industry payments over a decade, at a median of $48, with the top 0.1 percent averaging nearly $2 million.
Nothing anywhere answers the question "what should this hour cost?"
Those are different questions serving different purposes. Disclosure protects patients from undisclosed influence, which matters. Price transparency protects professionals from being systematically underpaid, which also matters, and which nobody has ever built for.
The striking asymmetry is that the profession has an elaborate public infrastructure recording payments to physicians, and no infrastructure at all recording what physicians should reasonably expect to receive.
The professionals are the only participants in this market without a price list.
What would actually fix it
Publish realized rates, contributed by clinicians. Not advertised rates, not what someone thinks they should charge, but what was actually paid: channel, specialty, setting, hours, rate, and whether the client-side price was disclosed. Median and interquartile range by specialty and channel.
Require verified identity. This is what makes the difference between a useful benchmark and a forum thread. Anonymous rate reports are unverifiable, inflate over time, and are worth nothing to the person trying to set a rate. Every contributor being a verified clinician in a stated specialty and setting is the entire basis of credibility.
Report the spread where it is knowable. In channels where the client-side price is discoverable, publishing both numbers changes negotiating positions immediately.
Give contributors the benefit. The natural design is reciprocal: you see the distribution because you contributed to it. That is also the only incentive structure that produces honest data at scale, since nobody has any other reason to disclose what they were paid.
And treat it as an index, published annually. Realized median and interquartile hourly compensation by channel, crossed with specialty, setting, career stage, and region, with a spread statistic showing intermediary margin where it can be established. That artifact does not exist for any health profession, and the first credible version of it would be cited for years.
A note on the channels that pay least and market hardest
There is an inverse relationship in this market that is worth stating explicitly, because it catches almost every clinician at some point.
The channels that pay the least market the most aggressively. Survey panels send recruitment emails continuously. They are easy to join, they onboard in minutes, they pay reliably, and they require no negotiation. Everything about them is frictionless, which is exactly why they are the first paid channel most clinicians encounter.
The channels that pay ten times more do essentially no marketing to clinicians at all. Expert witness work arrives through attorneys who found you some other way. Advisory roles arrive through a founder who was given your name. High-value consulting arrives because someone recommended you.
The high-paying channels are relationship-routed and therefore invisible to anyone without the relationship. The low-paying channels are advertised and therefore visible to everyone.
Which means a clinician's realized rate is substantially determined by their professional network rather than by their expertise, and the clinicians with the weakest networks, the early-career, the community-based, the recently retired, are systematically routed to the bottom of the price distribution.
This is worth naming because it reframes the individual advice. Knowing your worth is necessary and insufficient. The binding constraint for most clinicians is not that they price badly. It is that only one channel ever found them.
What you can do now
If you sell your expertise
Find out what your buyer pays. For expert network calls in particular, the industry's own published pricing indicates clients typically pay $1,000 to $1,400 an hour. Knowing that does not entitle you to it and it does change how you evaluate an offer.
Convert everything to an hourly rate before accepting. A per-survey or per-case fee is not a rate until you divide by the time it actually takes, including the screening questions you did not get paid for.
Ask three colleagues in your specialty what they charge. Yes, it feels awkward. The awkwardness is worth several thousand dollars a year, and the norm against it exists for no defensible reason.
Keep your own record. Channel, client type, hours, rate, and how it went. After ten engagements you will have a better personal benchmark than anything published.
Price the scarce thing, not the generic thing. Your value is highest where a machine cannot substitute: specific operational experience, unusual case exposure, judgment on the atypical. Generic literature summary is now worth close to nothing, and pricing it as though it were 2015 is leaving money on the table in one direction and misrepresenting your value in the other.
Do not let the first channel that finds you set your price for a decade. Many physicians anchor on the rate from their first paid engagement and never revisit it.
If you buy clinical expertise
Understand what your intermediary is charging. If you are paying $1,200 an hour and your expert is receiving $300, you are paying $900 for matching and compliance. That may be entirely worth it. It should be a decision rather than an assumption.
Recognize that prestige is a weak proxy for usefulness. The most published expert is frequently the most committed and least available, and community operators with directly relevant experience are systematically underpriced.
If you represent a profession
Publish a rate benchmark. Specialty societies publish compensation surveys for employment and almost nothing about expertise sales, despite having exactly the membership needed to produce it. This is a straightforward member service that no society currently provides.
Frequently asked questions
How much should a physician charge for consulting? It depends heavily on the channel, and the spread is enormous. Published industry sources indicate expert networks pay experts roughly $200 to $500 an hour while charging clients $1,000 to $1,400, physician expert witness rates cluster between $300 and $800 an hour, and survey work pays roughly $1 to $6 per minute. The most useful step is to convert any offer to an hourly equivalent and compare against colleagues in the same specialty.
How much do medical surveys pay physicians? Physician-facing community resources report roughly $1 to $6 per minute of survey time, which translates to between about $60 and $360 an hour before accounting for unpaid screening questions. It is generally the lowest-paying channel for clinical expertise.
What do expert networks pay physicians? Industry sources indicate experts are typically paid $200 to $500 per hour while clients are charged $1,000 to $1,400 for the same call, with only high-demand key opinion leaders exceeding $1,000 on the expert side.
What do physician expert witnesses charge? Community-maintained databases indicate most physicians set rates between $300 and $800 per hour, with meaningful variation by specialty, by activity type such as record review versus deposition versus testimony, and by market.
Does Open Payments show what physicians are paid per hour? No. Open Payments records the fact and amount of industry payments comprehensively, with no hours, scope, or deliverable attached. A given payment could represent forty hours of substantive work or a single engagement, which is why it cannot function as a rate benchmark.
Why is there no published rate card for clinical expertise? Because price information is destroyed at every step: intermediaries disclose one side of the transaction, per-item fees obscure hourly equivalents, equity compensation has no stated cash value, and professional norms discourage clinicians from comparing fees. Nobody records what was actually paid, so each clinician sets rates from scratch.
The bottom line
Clinical judgment is sold into at least six markets at prices differing by a factor of ten to twenty for the same hour of the same person, and the variable that determines where a clinician lands in that range is not their expertise. It is whether they happened to find the right channel and knew what to ask for.
Every intermediary in the market can see the full distribution. The professionals selling into it can see one number, their own, on one engagement, with no context.
Healthcare has spent a decade building an elaborate public record of what industry pays physicians. It has built nothing recording what physicians should expect to receive, which is the number that would actually help them.
The cardiologist who charged $400 for a call billed at $1,200 did nothing wrong and got no bad deal by the standards she had available. She simply had no standards available.
That is not a market failure that regulation solves. It is one that a few thousand verified clinicians telling each other the truth would solve in about a year.

Evidence note: expert network pricing and market size figures come from Inex One industry analyses (2024 and 2026). Survey and expert witness rate ranges come from Physician Side Gigs, a physician community resource that maintains rate databases, and represent community-reported ranges rather than audited data. Industry payment distribution figures come from JAMA analysis of CMS Open Payments (2024). Rate figures throughout are typical ranges and vary substantially by specialty, market, and engagement type. Nothing here is tax, legal, or financial advice.
