Sedation is the line item that turns a predictable dental quote into an unpredictable one, and the reason is buried in the billing codes. Nitrous oxide and oral sedation are flat fees. IV sedation and general anesthesia are not. They are billed by the clock, in 15-minute increments, which means the number you were quoted assumed a procedure length nobody can promise.
Understanding that one mechanic is worth more than any other piece of information on this page. Everything below is 2026 data from published fee schedules, and the figures are broken out by tier because your bill will be too.
What Does Sedation Dentistry Cost Without Insurance?
Each row below is the range across four published schedules: Alaska’s Medicaid dental fee schedule effective January 1, 2026, New York’s Official Workers’ Compensation Dental Fee Schedule effective November 13, 2025, Delta Dental of Washington’s published fee schedule (dated 2023), and published private-practice self-pay prices. The low and typical columns are regulated or negotiated allowables in most rows, so treat them as the floor a cash payer can point at rather than the price a private office will quote.
| Sedation type (CDT code) | Low | Typical | High |
|---|---|---|---|
| Nitrous oxide, per visit (D9230) | $57 | $100 | $140 |
| Oral conscious sedation, per visit (D9248) | $211 | n/a | $215 |
| IV moderate sedation, first 15 min (D9239) | $108 | $125 | $405 |
| IV moderate sedation, each added 15 min (D9243) | $108 | $125 | $385 |
| Deep sedation or general anesthesia, per 15 min (D9222/D9223) | $93 | $171 | $185 |
| One hour of IV moderate sedation (4 increments) | $432 | $500 | $1,560 |
| One hour of deep sedation or general anesthesia | $372 | $683 | $740 |
| Facility fee if done outside the dental office (G0330) | $1,319 | n/a | $3,071 |
Only two of the schedules reviewed here carry a fee for oral conscious sedation, and they land within four dollars of each other, at $211 in New York and $215 at Delta Dental of Washington. Both are allowables rather than retail cash quotes, so a private office setting its own fee is free to charge more.
The 15-minute math, spelled out
This is the part to internalize. D9239 pays for the first 15 minutes of IV moderate sedation and D9243 pays for each subsequent 15 minutes. D9222 and D9223 do the same job for deep sedation and general anesthesia.
On New York’s schedule, both IV increments are $125. So:
- 30 minutes of IV sedation: 2 increments, $250
- 60 minutes: 4 increments, $500
- 90 minutes: 6 increments, $750
At the Portland oral surgery practice’s published self-pay rate, the first increment is $405 and each subsequent one is $385. So:
- 30 minutes: $405 plus $385, or $790
- 60 minutes: $405 plus three at $385, or $1,560
- 90 minutes: $405 plus five at $385, or $2,330
General anesthesia works the same way. New York allows $185 for the first 15 minutes and $185 for every additional 15, and Alaska allows $170.76 flat for each. An hour is therefore $740 in New York and $683.04 in Alaska.
Two oddities in that data are worth flagging. First, every schedule reviewed here prices the subsequent increment at or near the first, so there is no volume discount as the case runs long. Second, on New York’s schedule, a 15-minute increment of general anesthesia ($185) costs less than the flat oral conscious sedation fee ($211). General anesthesia only becomes the expensive tier because it keeps billing.
What Drives the Price
Procedure length. For the IV and general anesthesia tiers this is the whole story. A case that runs 30 minutes longer than planned is two more increments, which is $250 to $770 more depending on the office.
Who is legally allowed to administer it. Permit levels are set state by state by the dental board, not nationally. Texas, for example, requires a separate permit for nitrous oxide and then four escalating levels: Level 1 minimal sedation, Level 2 moderate enteral sedation, Level 3 moderate parenteral sedation, and Level 4 deep sedation or general anesthesia. Texas also requires in-office inspection of Level 2, 3 and 4 permit holders who received their permit after March 1, 2018. Offices that hold only a nitrous permit have to refer you out for anything deeper, which adds a second provider’s fee.
Whether a dental anesthesiologist is brought in. When a general dentist does not hold a deep sedation or general anesthesia permit, a separately licensed dental anesthesiologist or CRNA may come to the office. That person bills their own fee, on their own claim, on top of the dentist’s fee for the dental work.
Where the case is done. Doing general anesthesia in a hospital or ambulatory surgery center adds a facility charge that has nothing to do with your teeth. Under the CMS rules effective January 1, 2024, the hospital outpatient facility payment for dental rehabilitation under code G0330 is $3,070.81 and the ASC rate is $1,318.93, per the AAPD. The AAPD notes explicitly that dentists’ professional fees are separately billable and not affected by those facility rates, so a hospital-based case produces at least three bills.
The patient’s age and health status. Pediatric general anesthesia is priced as its own service. The Portland practice publishes a range of $800 to $1,300 for it rather than a per-increment fee.
Cash Price vs. Insurance
Dental plans treat sedation inconsistently. Nitrous oxide is often excluded outright as a comfort service. Oral conscious sedation and IV sedation are frequently covered only when the plan agrees the sedation was medically necessary, which usually means an oral surgery procedure rather than a filling done on an anxious patient.
The more useful thing to know is that general anesthesia for dental treatment is not always a dental claim at all. The AAPD’s policy on third-party reimbursement asks payors to include sedation, general anesthesia and related facility services as health insurance benefits “without discrimination between the medical or dental nature of the procedure,” and for very young children and patients with special health care needs, those services are commonly processed under medical benefits rather than dental. The AAPD also encourages states to pass laws requiring payors to cover facility and anesthesia costs tied to children’s oral health care, and a number of states have.
For a cash payer, this matters in a different way: if the case is medically indicated and would be billed to medical insurance for an insured patient, it is fair to ask the office and the facility for their medical self-pay rate rather than their dental fee schedule. Those are often two different numbers for the same service.
How to Pay Less
1. Ask what tier is clinically on the table before you assume the deepest one. If nitrous is offered as an appropriate option for your procedure, it is $57 to $140 instead of $500 to $1,560 for an hour of IV. Which tier is appropriate is a clinical judgment made by your dentist, so the move is to ask what your options are, not to talk anyone out of one.
2. Bundle procedures into a single sedation appointment. Because the time-based charge starts over every visit, three separate sedated appointments means paying the first-increment fee three times. At the Portland practice’s rates, that is $405 charged three times instead of once. Ask whether the treatment can be staged into one longer session.
3. Get the sedation quoted as its own written line, with an assumed duration. A quote that says “IV sedation, $405” is not a quote, it is a starting price. Ask for the first-increment fee, the subsequent-increment fee, and the estimated number of increments. Then ask what happens if the case runs long. Our guide to negotiating medical bills covers the language that works when the final bill exceeds the estimate.
4. Ask whether the case can be done in the dental office instead of a hospital. The facility fee alone is $1,319 to $3,071. If the office and the anesthesia provider can do the case in-office under the dentist’s permit level, that entire charge disappears.
5. If a hospital is unavoidable, apply for charity care before the appointment, not after. Nonprofit hospitals are required to have financial assistance policies, and the facility bill is the one they apply to. Our guides to hospital charity care and getting an itemized bill cover how to request both, and the fair price tool will tell you whether a quoted figure is in a normal range.
6. Ask the facility and the anesthesia provider separately. Three bills means three negotiations. The anesthesia provider is usually a separate business from both the dentist and the hospital, and its self-pay rate is separately negotiable.
The Bottom Line
The sedation tier and the clock decide the price. Nitrous oxide is a flat $57 to $140. Oral conscious sedation is a flat $211 to $215 on the two published schedules that carry it. IV sedation and general anesthesia are metered in 15-minute increments that do not get cheaper as the case runs, which is why an hour ranges from $432 to $1,560 depending on whose fee schedule you are standing in front of.
Get all three numbers in writing before the appointment: the first increment, each additional increment, and the expected duration. If a hospital or surgery center is involved, get its facility estimate separately. And price the surrounding work as its own quote too, whether that is wisdom teeth removal, a frenectomy, gum surgery, or the dental X-rays that come before any of it.
