Allergy shots are one of the few treatments in American healthcare where no single number tells you anything useful. One shot visit can cost less than a sandwich. The catch is that you go back roughly forty times in the first year, and the extract being injected is billed as a completely separate service.

That two-part structure is why quotes swing so wildly. This guide takes the bill apart into the three billing codes that actually show up on it, shows what Medicare pays versus what allergy practices charge cash patients, adds the whole multi-year course up, and prices the sublingual alternative that is sold almost entirely as a cash subscription.

What Do Allergy Shots Cost Without Insurance?

Three codes carry almost the entire cost of subcutaneous immunotherapy:

  • CPT 95165 is the allergenic extract preparation, billed per dose. CMS defines a dose as a 1 cc aliquot drawn from a multi-dose vial and caps Medicare billing at 10 doses per vial.
  • CPT 95115 is a single injection at one visit.
  • CPT 95117 is two or more injections at the same visit, which is common because allergists often split incompatible allergens (mold and pollen, for example) into separate vials.

Here is what each one costs across the sources we checked in September 2026. The “low” column leans on 2026 Medicare rates and the cheapest published clinic self-pay price, the “average” column uses the average charge providers actually submitted to Medicare in the most recent national claims data, and the “high” column uses the highest published clinic self-pay price.

Service/TypeLowAverageHigh
Single injection visit (CPT 95115)$10$27$30
Two or more injections, one visit (CPT 95117)$12$36$40
Extract preparation, per billable dose (CPT 95165)$16$29$40
One 10-dose vial of extract (95165 x 10)$160$290$400
First year: weekly build-up plus early maintenance$800$1,700$2,800
Full three-to-five-year course$2,000$4,500$9,000
Sublingual allergy drops, cash subscription, per month$39$79$99

The Medicare anchors come from the 2026 Physician Fee Schedule relative value file released for the July 2026 quarter. CPT 95115 carries 0.31 total RVUs, 95117 carries 0.37, and 95165 carries 0.52 in the office setting. At the 2026 conversion factors of $33.4009 and $33.5675, that works out to $10.35 to $10.41 for a single injection, $12.36 to $12.42 for a multi-injection visit, and $17.37 to $17.45 per extract dose, or about $174 for a full 10-dose vial.

CMS national claims data for the 2024 data year, released in 2026, shows what providers actually put on the bill before any discount. The average submitted charge was $27.35 for 95115, $36.33 for 95117, and $29.46 per dose for 95165 in the office setting. Medicare allowed $9.51, $11.63 and $13.87 respectively, so the billed-to-allowed gap is roughly two to three times.

Published clinic self-pay lists bracket the same range. Midwest Allergy & Asthma Clinic posts $30 for a single injection, $40 for multiple injections and $40 per unit of serum preparation. Allergy and Asthma Clinic, PC in Roanoke posts $17 for a single injection, $26 for multiple, $16 per 95165 unit, and $160 for a 10-unit maintenance vial.

The first-year and full-course totals in the table are our arithmetic on top of those unit prices, not a figure any single source publishes. ACAAI describes shots roughly weekly for about seven months, then every two weeks, then eventually every four weeks, for a total of three to five years. That is about 40 visits in year one and 13 to 26 a year after that, with one to three vials mixed per year.

What Drives the Price

How many vials your extract needs

This is the single biggest swing factor and it is set by your test results, not by the clinic’s price list. Some allergens cannot be mixed together, so a patient allergic to molds and pollens may need two or three separate vials where another patient needs one. Every extra vial is another 5 to 10 units of CPT 95165. At $40 a unit, a third vial adds roughly $400 to the year.

Build-up versus maintenance

Build-up is the expensive phase. Weekly visits for about seven months front-load both the injection fees and the vial turnover. Once you reach maintenance, the same treatment costs a fraction as much per year because you go every two to four weeks and the vial lasts longer.

Whether the clinic bills 95115 or 95117

If your allergens are split across two vials, you get two injections at one visit and the practice bills 95117 instead of 95115. That is a real clinical decision, but it is worth knowing that it raises the per-visit price by $9 to $10 at every clinic we checked, times roughly 40 visits in year one.

Where the shot is given

CMS pays 95115 and 95117 only in an office setting, so hospital-owned allergy clinics have to route the injection differently, and hospital outpatient departments layer a facility fee on top of the professional charge. An independent allergy practice is almost always the cheaper place to get the same shot. Our guide to hospital price transparency explains how to pull a hospital’s posted rate for a specific code before you commit.

The testing that comes first

You cannot start immunotherapy without knowing what to put in the vial, and skin or blood testing is billed separately from everything above. See allergy testing cost without insurance for what that step runs, plus the doctor visit cost without insurance for the consult itself.

Cash Price vs. Insurance

Allergy immunotherapy is one of the clearer cases where a cash payer can land close to an insured patient’s total, and occasionally beat it.

The reason is the copay structure. Insured patients frequently owe a per-visit copay of $20 to $40 for a service Medicare values at $10 to $12. Over 40 visits in year one and three to five years of treatment, a copay can exceed what a self-pay patient negotiates. A cash patient who asks the practice for the self-pay rate up front is often quoted something in the $17 to $40 per-visit band, which is not far off the copay and comes with no deductible to burn through first.

Where insurance clearly wins is the extract. A patient needing three vials a year is looking at $480 to $1,200 in 95165 charges annually at self-pay list rates, and most plans cover that once the deductible is met. If you have a plan with a low deductible, use it for the vials.

The important move for a cash payer is to get the whole thing priced as a package before the first vial is mixed. Ask for the per-unit 95165 charge, how many units per vial, how many vials the allergist expects, and the per-visit injection charge. That is four numbers, and together they let you multiply out the year yourself.

How to Pay Less

Get a written self-pay quote for the full first year, not per shot. Clinics that publish self-pay charges (like the two we cite above) generally honor them, but the quote you want is 40 visits plus expected vials. Practices rarely volunteer that math.

Ask whether the extract can be prepared by the allergist and injected somewhere cheaper. CMS billing guidance explicitly contemplates this: the allergist provides the extract and a primary care office administers the shot, with each billing its own code. If your allergist’s per-visit charge is high, a nearby primary care office or an employer clinic may inject the same vial for less.

Push back on hospital facility fees. If your shots are given in a hospital-affiliated clinic, ask for the itemized bill and check whether a facility charge appears alongside the injection code. Facility fees are often the difference between a $25 shot and a $120 shot, and they are negotiable.

Negotiate the balance, and ask about financial assistance. Immunotherapy bills arrive in small pieces, which makes them easy to ignore until they add up. Our medical bill negotiation guide covers the scripts, and hospital-owned allergy clinics are usually covered by the parent system’s charity care policy.

Check community clinics. Federally qualified health centers and other sliding-scale providers set fees against your income, and some run allergy services. See free and sliding-scale clinics for how to find one and what documentation to bring.

Price sublingual immunotherapy as an alternative. Telehealth allergy-drop companies sell immunotherapy as a flat monthly subscription. Curex publishes a $39 per month plan and a $99 per month self-pay plan with no copays, plus a $199 cash price on lab testing. Wyndly publishes $99 a month billed quarterly. At $470 to $1,190 a year, drops can undercut a shot schedule for a cash payer. The trade-off is regulatory: ACAAI notes the only FDA-approved sublingual immunotherapy products in the U.S. are tablets for ragweed, grass pollen and dust mite, so custom liquid drops are prescribed off-label and are essentially never covered by insurance.

The Bottom Line

Budget $800 to $2,800 for the first year of allergy shots as a cash payer, and $2,000 to $9,000 for the full course, depending mostly on how many extract vials your allergen profile requires and whether you are treated in an independent office or a hospital-owned one.

Before you start, get four numbers in writing: the per-unit 95165 charge, units per vial, expected number of vials, and the per-visit injection charge. Then compare that total against a sublingual subscription at $39 to $99 a month. If the shots are for asthma control rather than hay fever, it is also worth pricing the medication side, including inhaler costs, montelukast and biologics like Xolair, before committing to a multi-year schedule.
