How Much Are Allergy Shots? Medicare, Commercial & Cash Prices

Per-visit cost depends entirely on your payer and your clinic's billing classification. The 2025 CMS Physician Fee Schedule sets Medicare-allowed amounts at $11.97 for CPT 95117 (multi-allergen injection) and $13.91 per dose for CPT 95165 (vial preparation) — meaning a 10-dose vial day allows $139.10 Medicare total. Commercial PPO patients typically pay a $15–$40 specialist copay per visit once their deductible is met. Medicare Part B patients owe 20% coinsurance, roughly $3–$32 per visit after the $257 annual deductible. At hospital outpatient departments, the same visit can generate a bill of $200–$2,400+ due to facility fees layered on top of the professional fee. Cash-retail at a freestanding clinic typically runs $40–$150 per shot visit.

Year 1 costs roughly double maintenance years because of the build-up phase. Per the Cox 2011 Practice Parameter Third Update (J Allergy Clin Immunol 2011;127[1 Suppl]:S1-S55), the conventional build-up protocol involves approximately 24–28 weekly injections over 3–6 months before transitioning to maintenance every 2–4 weeks. Year 1 typically totals about 39 visits (26 build-up plus 13 early-maintenance) versus approximately 14–20 maintenance visits in Years 2–5. Vial-preparation (CPT 95165) costs also concentrate in Year 1 because extract dilutions require more frequent replacement during dose escalation per FDA-licensed extract stability requirements. At $42 average specialist copay (KFF 2024 Employer Health Benefits Survey), 39 Year-1 visits alone generate $1,638 in stacked copays before any vial charges.

Yes — virtually all major US insurance plans cover subcutaneous allergy immunotherapy (SCIT) when prescribed by a board-certified allergist for a medically necessary indication such as allergic rhinitis, asthma, or venom hypersensitivity. Coverage spans BCBS, Aetna, UnitedHealthcare, Cigna, Kaiser, Humana, Anthem, Medicare Part B, Medicaid (with state-specific exceptions), and Tricare. The key variables that determine your actual out-of-pocket cost are: (1) whether your clinic is a hospital outpatient department — HOPD billing can multiply patient costs 10–40×; (2) your deductible status — HDHP enrollees may owe the full allowed amount until the deductible is met; and (3) whether your plan uses a flat specialist copay or a percentage coinsurance model. California Medi-Cal is a notable exception: it explicitly excludes antigen-prep codes 95145–95165 per the DHCS Allergy Manual.

CPT 95115 covers a single-antigen injection; CPT 95117 covers two or more antigens in a single visit and is the dominant code for patients receiving multi-component vials. The 2025 Medicare-allowed amounts differ slightly: 95115 allows $10.35 vs 95117 at $11.97. Most maintenance SCIT patients should see CPT 95117 on their EOB, not 95115. If you see 95115 but are receiving injections from multiple vials, ask your billing department to verify the coding — some practices default to 95115 when 95117 would be the more accurate and slightly higher-reimbursed code. The distinction matters more on the provider's revenue side than on the patient-owed side, since copay and coinsurance structures usually apply the same way to both codes.

A hospital outpatient department (HOPD) is a clinic that is owned by and legally part of a hospital system, even when it physically looks like and operates as a standard allergist's office. When a clinic is HOPD-classified, it can bill a facility fee in addition to the professional fee — a cost structure that applies the Outpatient Prospective Payment System (OPPS) rate schedule rather than the Physician Fee Schedule. This is why the 2025 Medicare-allowed amount of $11.97 for CPT 95117 can expand to hundreds or thousands of dollars in billed charges at the same visit. A documented example: Kaitlin Johnson's 40-allergen skin test at M Health Fairview in Minneapolis generated a $24,400 bill in 2024 (PBS NewsHour Weekend), versus $800–$1,827 at nearby freestanding clinics for the same panel. Before scheduling at any new clinic, ask in writing: 'Is this location a hospital outpatient department?'

Medicare Part B covers SCIT under the physician office benefit. The 2025 CMS Physician Fee Schedule sets $11.97 allowed for CPT 95117 and $13.91/dose for CPT 95165. After the $257 (2025) or $283 (2026) Part B annual deductible, Medicare pays 80% of the allowed amount and the patient owes 20% coinsurance. A typical maintenance visit — 95117 plus a 10-dose vial of 95165 — allows $158.82 and generates a patient obligation of approximately $31.76 in coinsurance. A Medigap supplement policy eliminates that 20% entirely, making maintenance SCIT one of the most affordable services in Original Medicare. Without Medigap, a 14-visit maintenance year generates approximately $445 in annual coinsurance costs — more than offset by savings on antihistamines, nasal steroids, and acute-care visits that effective immunotherapy may reduce.

Yes. Allergy shots are a qualified medical expense under IRS Publication 502 and are eligible for reimbursement from Health Savings Accounts (HSAs), Flexible Spending Accounts (FSAs), and Health Reimbursement Arrangements (HRAs). This means you pay with pre-tax dollars, effectively reducing the after-tax cost by your marginal tax rate — typically 22–32% for middle-income earners. Keep itemized receipts showing the service date, provider, and CPT codes for recordkeeping. The CARES Act of 2020 also confirmed that FDA-approved sublingual allergen tablets and prescribed compounded sublingual immunotherapy are eligible as IRC Section 213(d) medical expenses, so both SCIT and sublingual immunotherapy treatment costs qualify for HSA/FSA reimbursement.
