The subsidy is a symptom. Diagnose it before you fund it.
What was an exception a few years ago is becoming a standing operating expense for facilities that never budgeted for it. The scale of the shift is visible in the market data.
Subsidy requirements are now common and financially material.
What was an exception a few years ago is becoming a standing operating expense for facilities that never budgeted for it — driven by both labor cost and reimbursement.
Workforce scarcity is only one input. This is equally a reimbursement problem.
A subsidy is what remains when the market cost of maintaining coverage exceeds collectible professional revenue. Payer mix and contracted rates drive that revenue as much as wages drive the cost.
Diagnose the deficit before accepting it as permanent.
Workforce-, reimbursement-, payer-mix-, utilization-, coverage-model-, and contracting-driven deficits look identical on the invoice but call for entirely different responses.
Several levers can shrink the gap before a check is written.
Commercial contracting, payer-mix strategy, network positioning, carefully modeled No Surprises Act / IDR economics, and operating-model redesign can each move the number — in some cases substantially.
Some gap will remain — and that is a legitimate finding.
In genuinely constrained markets, the cost of capacity exceeds what any payer strategy can collect. The goal is not to eliminate every subsidy; it is to fund only the part that is truly unavoidable, and to structure it well.
A subsidy is not a diagnosis; it is the residual of one. When the cost of anesthesia capacity exceeds the professional revenue it can collect, the difference does not disappear — increasingly, the facility funds it. Before accepting that number as permanent, quantify the gap, diagnose why it exists, and test which levers — reimbursement, payer mix, contracting, network, operations — can actually change it.
Two curves that no longer meet
The economics of anesthesia coverage are breaking down in a specific, quantifiable way. The cost of securing a provider has risen sharply while the professional revenue that provider generates has been flat to declining. The facility sits in the middle of that widening gap because it cannot run an operating room without coverage.
Demand for anesthesia tracks surgical volume, which continues to grow with an aging population. Supply is constrained: a large share of anesthesiologists are within a decade of retirement, training pipelines are limited, and in some regions there is no local residency pipeline at all. The result is real wage pressure. Market participants describe per-diem stipends that have more than doubled in three years, with hospitals able to outbid ASCs because hospital margins can absorb costs that ASC margins cannot.
The reimbursement side has moved in the opposite direction. Average professional anesthesia reimbursement was reported to have fallen roughly 5.5% from 2019 to 2023 on a per-unit basis, even before accounting for wage inflation. When the cost of capacity rises while the revenue that capacity collects falls, the facility inherits the difference. That difference is the subsidy.
The anesthesia funding gap, in one picture
The subsidy is the residual after professional collections are applied against the required cost of maintaining coverage — not a standalone number.
Illustrative structure — proportions are conceptual, not benchmarks. Fulcrum Health Partners analysis. Every term on the left and the right is a lever; the residual in the middle is only as fixed as the organization allows it to be.
Characterized as a labor shortage, the only visible response is to pay more. Characterized as a gap between cost and collectible revenue, a wider set of levers comes into view — and several of them sit with the anesthesia group, not the facility.
Five forces, one invoice
A subsidy request rarely has a single cause. Five distinct forces push on the gap simultaneously; the invoice that lands on the facility's desk sums them into one number and hides which is doing the work.
Workforce
Constrained supply, aging cohort, and thin training pipelines raise the compensation required to secure coverage.
Reimbursement
Flat-to-declining unit reimbursement means the same clinical work collects less over time.
Payer Mix
Medicare and Medicaid pay a fraction of commercial rates; mix determines revenue per case.
Utilization
Providers paid to staff rooms that run light or start late convert capacity into idle cost.
Coverage Model
Room count, hours, call burden, and MD/CRNA structure set the fixed cost of being open.
The Medicare anesthesia formula — and why it is structurally different
Anesthesia is not paid like most physician services. Rather than a single relative-value calculation, Medicare pays anesthesia on a units × conversion factor basis, and it uses a separate, much lower anesthesia conversion factor than the standard Physician Fee Schedule. Confusing the two is the most common error in these conversations.
National Medicare anesthesia conversion factor per unit (CMS CY2024–CY2026 PFS final rules). The standard PFS conversion factor — used for most other physician services — is a different, higher figure and should not be substituted here. Base units are fixed by procedure; time units generally accrue in 15-minute increments. Actual payment is adjusted for locality and applicable rules.
The point for executives is not the coding mechanics. It is that the Medicare anesthesia rate has been essentially flat in nominal terms for more than a decade — and therefore materially lower in real terms after inflation — while the wage required to staff a room has climbed. For any facility with meaningful Medicare or Medicaid volume, a portion of the funding gap is structural: government reimbursement was never designed to cover today's market cost of capacity, and no amount of contracting changes a government fee schedule.
Commercial reimbursement is where the leverage lives
Commercial anesthesia reimbursement varies widely — by payer, market, contract vintage, negotiated conversion factor, network status, product, and the group's own leverage. Two groups doing identical clinical work can collect very different amounts. That variability is precisely why a subsidy request should not be accepted as purely a labor-cost problem: the group's commercial contracts may be an equal or larger part of the economics, and unlike the Medicare CF, they can be renegotiated.
Not all subsidies are the same
Six deficits produce an identical line item and demand opposite responses. Paying more solves a workforce deficit but merely subsidizes a reimbursement or utilization deficit indefinitely.
| Deficit type | What is actually driving the gap | The response it calls for |
|---|---|---|
| Workforce-driven | A difficult recruiting market; the compensation required to secure coverage genuinely exceeds sustainable professional collections. | Redesign coverage; fund the residual. Some of this gap is real. |
| Reimbursement-driven | Commercial or government rates are inadequate relative to the required staffing cost — a revenue problem wearing a cost mask. | Renegotiate commercial contracts before funding permanently. |
| Payer-mix-driven | A high Medicare/Medicaid or otherwise unfavorable mix caps professional revenue regardless of rates. | Model and manage mix; quantify the government-pay share. |
| Utilization-driven | Providers are paid to cover rooms that are underused, run light, start late, or turn over slowly. | Optimize scheduling and block before adding dollars. |
| Coverage-model | Room count, hours, call, and MD/CRNA/CAA structure create cost beyond economically productive capacity. | Redesign the staffing model and hours to demand. |
| Contracting-strategy | The group's payer contracts are stale or were never renegotiated to current market economics. | Exhaust contracting leverage — including network options. |
Before negotiating the size of the subsidy, diagnose the reason it exists. A subsidy can reflect several of these deficits at once — the value is in decomposing one number into its causes, because each has a different owner and a different fix.
The Anesthesia Subsidy Diagnostic
Seven questions that convert a lump-sum request into an addressable problem. Fulcrum Health Partners framework.
| Ask | What to measure | If it's the driver |
|---|---|---|
| Is reimbursement adequate? | Effective conversion factor & collections by payer | Renegotiate |
| Is payer mix creating the deficit? | Revenue by payer per case; government-pay share | Model & manage mix |
| Is OR capacity underused? | Cases per room per provider day; block utilization | Optimize scheduling |
| Are staffing costs above market? | Compensation, locums spend, call structure | Redesign coverage |
| Are specific payers uneconomic? | Contribution margin by payer | Evaluate network strategy |
| Is out-of-network viable here? | Contracted vs. modeled NSA/IDR economics, net of cost | Evaluate selectively |
| Does a gap remain after all of the above? | Sustainable cost vs. optimized revenue | Structure the subsidy |
The levers that move the gap
A subsidy is the last lever, not the first. Five others should be tested in sequence, and the residual funded only after they are exhausted. No single lever is sufficient — reimbursement strategy cannot fix an inefficient operating model, and efficiency cannot solve genuinely inadequate reimbursement.
Commercial payer renegotiation
The first question is whether the group has exhausted its contracting leverage before asking the facility to fund the deficit permanently. Contract vintage, effective conversion factors, rate variation across payers, provider scarcity, surgical volume, facility relationships, and termination provisions all bear on what is achievable. Leverage is real but not universal — not every group can command large increases, and the analysis should be honest about which can.
Has the group exhausted payer contracting leverage before the facility funds the gap forever?
Payer mix
The identical staffing model produces very different economics at a commercially weighted ASC versus a facility with heavy government volume. Mix is partly a function of case selection, service-line strategy, and facility relationships — and it is measurable. See the illustrative comparison below.
Network strategy
Continued in-network participation with every commercial payer is not automatically rational. Targeted renegotiation from a credible termination position, selective non-participation, and narrowing participation are all options — but each must weigh patient access, referral and facility relationships, state law, No Surprises Act implications, network adequacy, operational burden, and reputation. This is a scalpel, not a hammer; indiscriminate termination is not the recommendation.
No Surprises Act & federal IDR
Anesthesia is squarely within surprise-billing protections: a patient at an in-network facility rarely chooses their anesthesiologist, so eligible out-of-network claims can proceed to Independent Dispute Resolution, where an arbitrator weighs each side's offer against the Qualifying Payment Amount. Through mid-2024, providers prevailed in roughly 80% of federal determinations, and the median anesthesia determination ran about twice the QPA. Meaningful — but not free money. A rational out-of-network position nets expected IDR reimbursement against administrative cost, collection friction, payment delay, legal risk, and payer/network consequences, then compares that to expected in-network reimbursement. IDR is a modeled strategy for certain groups and markets — not guaranteed arbitrage — and eligibility, QPA methodology, and the process itself remain contested and operationally heavy.
Operating model
OR and block utilization, first-case starts, room turnover, staffed-room count, coverage hours, call structure, staffing ratios, MD/CRNA/CAA configuration where clinically and legally appropriate, and locums dependence all determine how much productive work each paid provider-day yields. Efficiency will not cure inadequate reimbursement, but it routinely shrinks a gap that looks purely like a labor-cost problem.
Subsidy structure
If support remains necessary, structure is a lever in itself: fixed vs. variable support, collections or income guarantees, per-diem or per-room coverage, performance and productivity expectations, expense transparency, reconciliation mechanisms, and periodic rebasing. Arrangements should be structured and reviewed for fair-market-value, commercial-reasonableness, and applicable fraud-and-abuse considerations — issues to work through with counsel, not addressed here as legal advice.
Same staffing model, different economics
The figures below are illustrative — constructed to show the mechanics of payer mix, not benchmarks. They demonstrate how two facilities with the identical cost of coverage can face very different subsidy requirements based on mix and contracted rates alone.
Facility A · Strong commercial mix
Facility B · Government-weighted mix
Illustrative only. Assumes identical $2.4M cost of coverage and hypothetical per-case rates; not a market benchmark. The purpose is to show that a six-fold difference in subsidy can arise from mix and rates alone, with no difference in labor cost — which is why "the group needs another $X" is the wrong first question.

Each lever is tested before the next dollar of subsidy is committed. The residual that survives this sequence is the part of the gap that is genuinely unavoidable — and the only part that should become a permanent line item.
Before writing the subsidy check
An eight-step sequence that turns a reactive funding request into a disciplined decision. Each step narrows the gap and clarifies who owns the remainder.
Quantify the gap
How large is the true anesthesia operating deficit, on transparent assumptions?
Diagnose the cause
Workforce, reimbursement, payer mix, utilization, staffing model, or contracting — and in what proportion?
Benchmark payer economics
What is each payer actually contributing to, or detracting from, sustainability?
Evaluate contracting leverage
Where can commercial reimbursement realistically improve, and by how much?
Model network alternatives
What are the economics and risks of termination, non-participation, and applicable NSA/IDR pathways?
Optimize the operating model
Can staffing, hours, call, and OR utilization improve the productive yield per provider-day?
Determine the residual subsidy
After realistic improvements, what funding gap actually remains?
Structure the subsidy
If support is still required, structure it transparently and intentionally — with expectations, reconciliation, and rebasing.
Anesthesia group levers vs. facility levers
The better question is not "how much does the group need?" but "why does the gap exist, and which party is best positioned to address each component?"
The anesthesia group controls
- Payer contracts and negotiated rates
- Provider compensation and staffing model
- Billing, coding, and collections performance
- Network participation decisions
- Locums dependence and call structure
The facility influences
- OR and block utilization
- Surgical scheduling and first-case starts
- Payer mix and case selection
- Coverage requirements, rooms, and hours
- Strategic payer relationships and volume
Quantifying the gap, agreeing the diagnosis, and structuring any residual support are joint work. The facility that funds a deficit it did not diagnose is paying for problems the group is better positioned to fix — and vice versa.
Fund the gap you can't close — not the one you haven't tried to
The anesthesia subsidy is not going away as a topic; in constrained markets, the cost of maintaining capacity genuinely exceeds collectible professional revenue, and a real residual will remain no matter how well an organization executes. This analysis does not claim otherwise.
What it argues is narrower and more useful: a subsidy request is the end of an analysis, not the beginning of one. Before it becomes a permanent operating expense, an organization should know how much of the gap is structural — driven by government reimbursement and genuine scarcity — and how much is addressable through reimbursement, contracting, network, and operating strategy.
That distinction is worth real money. A facility that funds an undiagnosed gap pays twice: once through the economics of the surgical facility itself, and again through support the group might have closed through its own contracts, collections, or coverage design. The discipline of decomposing one number into its causes — and assigning each cause to the party best positioned to fix it — is where the leverage sits.
