ASC Anesthesia Stipend: Should Your Surgery Center Pay One?

Pay an ASC anesthesia stipend only after the anesthesia group has shown, with its own case and collections data, that a gap remains once you have fixed scheduling, room count and staffing. Any payment should be fair market value, set in advance in writing, and not tied to referrals. Some surgery centers pay one and many do not: in the Ambulatory Surgery Center Association's 2026 survey, 31% offered anesthesia providers financial assistance.

The pressure is real. A VMG Health survey reported by Becker's ASC found that the share of ASCs expecting to pay anesthesia stipends rose from 28% in 2024 to 44% in 2025, and that 60% of ASC leaders ranked anesthesia coverage among their top three financial challenges for 2026. The ASCA third-quarter 2026 survey of 307 centers in 44 states measured something different: what centers already offer. In it, 31% offered financial assistance to anesthesia providers, against 30% in 2024, and 76% reported adequate access to anesthesia providers, the highest share in ASCA's four anesthesia surveys. A stipend is common, but it is not inevitable.

Why anesthesia groups ask surgery centers for money

An anesthesia group earns most of its income from professional fees billed for each case. Its costs are mostly fixed. A CRNA or anesthesiologist assigned to your room is paid for the day whether the room runs eight cases or three. When collections per staffed room-day fall below the cost of staffing that room, the group asks the facility to cover the difference. The usual causes are:

• Payer mix. Low reimbursement from a high share of government payers is one of the barriers ASC leaders named in ASCA's 2026 survey. A center whose Medicaid share has grown can see collections per case fall even if case counts hold steady.
• Low volume per room. A room with four short cases and long gaps costs the group the same as a full room.
• Late starts and cancellations. A 45-minute late first case, or two same-day cancellations, turns paid anesthesia time into unbilled time.
• Clinician pay. Becker's, citing Bureau of Labor Statistics data, reports that CRNA pay has risen sharply since 2019 (Becker's ASC, August 2026). The group's cost per staffed day rises with it, while payer rates do not move as fast.
• Coverage expectations. Requests for late rooms, call coverage or a dedicated block anesthesiologist add hours without adding billable cases.

Each cause has a different fix. Some are the facility's to solve, some are the group's, and some can only be paid for.

How an ASC anesthesia stipend is usually structured

Support for anesthesia at a surgery center tends to take one of five shapes:

ASCA's survey shows how centers that offer assistance split across the main forms.

ASCA also found that centers owned only by physicians were less likely to offer financial assistance (23%), and that large centers, with five or more rooms, were more likely to (43%).

What to ask for before you agree to an ASC anesthesia stipend

A stipend request is a claim that costs exceed collections at your center. It is reasonable to ask for the evidence. Ask for at least the last 12 months of:

• Case logs by room and day, with anesthesia start and end times, so you can see billable time against staffed time.
• Collections per case, broken out by payer class. Use collections, not charges. Charges say little about what the group receives.
• Payer mix by case count and by collections, with the trend over two or three years.
• The staffing model. How many anesthesiologists and CRNAs cover how many rooms, the care-team ratio, and whether CRNAs are employed or contracted.
• Cost per staffed day, with the main components named: clinician pay, benefits, malpractice, billing and overhead.
• Lost time: late starts, cancellations, and gaps between cases, by surgeon and by room.

A group that wants support should be willing to share this under a confidentiality agreement. If the data cannot be produced, the size of the gap cannot be checked. For a fuller list, see AOC's checklist for reading an anesthesia stipend request. It is written for hospitals, but the same questions apply to a surgery center.

What to try before you pay

Part of many stipend requests is a scheduling problem. Anesthesia and ASC leaders quoted by Becker's ASC say groups long absorbed late starts, underused rooms, cancellations and add-ons. The same report expects centers with empty rooms and late starts to pay more for the same coverage. Before you agree to a number, test these levers:

• On-time first-case starts and shorter turnovers, measured and reported each week.
• Block release rules that free unused surgeon time early enough to fill it.
• Room count. Running fewer, fuller rooms on light days.
• Care-team ratio. Where state law, payer rules and the federal ASC supervision rule (42 CFR 416.42) allow, a different ratio of anesthesiologists to CRNAs changes the cost per room. AOC has set out what 1:2, 1:3 and 1:4 cost.
• Cancellation control. Pre-operative screening that catches cases likely to cancel on the day.

Worked example (modelled)

The figures below are modelled, not benchmarks. Assumptions: 3 operating rooms, 250 operating days a year, 4,500 cases a year, average group collections of $450 per case, and a group cost of $3,200 to staff one room for one day. Replace each figure with your own data.

In scenario A the group's request works out to about $83 per case ($375,000 across 4,500 cases). Scenario B assumes surgeons bring enough extra cases to fill the time that on-time starts free up. Scenario C assumes surgeon schedules can fit two rooms. Neither assumption holds everywhere. The point is that the gap depends on how the rooms run, not only on what payers pay. A stipend that pays for scenario A every year also pays for the inefficiency behind it.

Fair market value and the anti-kickback question

Money that moves between a surgery center and an anesthesia group, including an ASC anesthesia stipend, raises federal and state fraud-and-abuse questions, starting with the federal Anti-Kickback Statute. In a physician-owned ASC, the owners are often the surgeons who bring the cases, so the structure of any payment matters. The safe harbor for personal services and management contracts (42 CFR 1001.952(d)) protects only arrangements that meet all of its conditions, and those conditions are the usual test. In general terms:

• The agreement is in writing and signed, covers all the services the group provides to the center, and runs for at least one year.
• The method for setting the payment is fixed in advance, is consistent with fair market value in an arm's-length deal, and does not take into account the volume or value of referrals or other business between the parties.
• The services paid for, such as coverage hours, call or administrative duties, do not exceed what is reasonably necessary for a commercially reasonable purpose.
• The amount is backed by a documented fair market value analysis. AOC has described what an anesthesia fair market value opinion should contain.
• It is reviewed when the facts change, such as room count, payer mix or staffing model.

Watch for money flowing the other way as well. In Advisory Opinion 12-06 (2012), the HHS Office of Inspector General reviewed a proposal in which an anesthesia group would pay surgery centers per-patient fees for "management services" that the facility fee already covered. It concluded that the proposal could potentially generate prohibited remuneration, even with federal health care program patients carved out, because the centers "would be paid twice for the same services."

This is not legal advice. Have healthcare counsel review the structure and the agreement before anything is signed or renewed.

What to check

• You have 12 months of case logs with anesthesia times, by room and day.
• You have collections per case by payer class, not charges.
• You know the payer mix trend, including the Medicaid share.
• The group has named its staffing model, care-team ratio and cost per staffed day.
• You have measured first-case delays, turnovers and same-day cancellations.
• You have tested block release rules and whether fewer rooms could carry the volume.
• The proposed structure fits the cost driver: per room-day for coverage gaps, a collections guarantee for payer-mix gaps.
• The payment method is set in advance, in writing, at fair market value with a written analysis, and does not vary with referrals.
• The agreement has measurable duties, a term of at least a year, and a date to review the numbers.
• Healthcare counsel has reviewed the arrangement.

If an anesthesia group has asked your center for a stipend, or for a larger one at renewal, AOC can check the request against your own case, time and collections data. AOC works for a fixed fee. It places no clinicians, does no billing and takes no share of savings, and it shows its workings so the center and the group can both check them. Our stipend and contract review covers the agreement itself. Book 15 minutes with Andrew Woodmancey, or request a benchmark review.
