How Much Do Dog Allergy Shots Cost? Every Payer Scenario

This page is about subcutaneous immunotherapy (SCIT) — allergy shots injected into a HUMAN patient who is sensitized to dog allergens like Can f 1 or Can f 5. It has nothing to do with CYTOPOINT (lokivetmab) or Apoquel (oclacitinib), which are veterinary biologics or oral medications injected into or given to the dog to treat the dog's own atopic dermatitis. Those veterinary products cost $40–$90 per month per dog and are billed to pet insurance or paid directly. Human SCIT for dog allergy is billed to the human patient's health insurance under CPT codes 95117, 95165, and 95004. If you are looking for information about treating your dog's skin allergies, this is not the right resource.

Year 1 is the most expensive year for HDHP enrollees because the deductible has not yet been met. An initial skin-test workup (CPT 95004 × 40 allergens plus an E/M code) alone may run $400–$1,200 in allowed amounts, all applied to the deductible. The first vial preparation (CPT 95165 × 10 doses at commercial allowed $30–$50/dose) can add $300–$600 before deductible is reached. Once the deductible is satisfied, the patient owes only 10–20% coinsurance per visit. Strategic timing matters: starting build-up in January lets you burn through the deductible in the first 2–3 visits, making the rest of the year cheaper. Total Year 1 HDHP estimate: $1,500–$3,000 depending on plan and allergen panel size. Year 2+ maintenance is typically $300–$700 annually post-deductible.

Yes. Allergy shots (SCIT) administered to a human patient qualify as a medical expense under IRS Publication 502 and Section 213(d) of the Internal Revenue Code. HSA and FSA funds can be used to pay for copays, coinsurance, deductible amounts, and any out-of-pocket costs associated with SCIT. Veterinary expenses — including CYTOPOINT, Apoquel, or vet allergen-specific immunotherapy for your dog — do not qualify as IRC §213(d) medical expenses for your human HSA or FSA (the narrow exception is qualified service animal expenses). Mileage to and from your allergist's office may also be deductible at the IRS medical mileage rate of $0.21/mi in 2025 (IRS Notice 2025-5) if you itemize medical expenses on Schedule A.

Approximately 16.5% of dog-sensitized adults are monosensitized to Can f 5 — prostatic kallikrein produced exclusively in the prostate glands of intact male dogs, absent in females and neutered males (Ozuygur Ermis et al., Allergy 2023). In a randomized double-blind placebo-controlled challenge, Schoos et al. (JACI Pract 2020) found that all 7 Can f 5-monosensitized children had no reaction to female dog extract. For these patients, the most cost-effective solution is adopting a female or neutered male dog — the SCIT cost is literally zero. Component-resolved IgE testing (distinguishing Can f 1 lipocalin from Can f 5 prostatic kallikrein from Can f 3 serum albumin) is the prerequisite diagnostic step before committing to any SCIT protocol.

Medicare Part B covers SCIT after the annual Part B deductible ($257 in 2025; $283 in 2026 per CMS announcement November 14, 2025). After the deductible, Medicare pays 80% of the allowed amount and the patient owes 20% coinsurance. At 2025 allowed rates: CPT 95117 (injection) = $11.97 × 20% = $2.39/visit; CPT 95165 × 10 doses = $139.10 × 20% = $27.82. A combined maintenance visit (shot plus vial) costs the patient approximately $31.76 in coinsurance. Over a maintenance year of 14 visits with 1 vial prep, the patient owes roughly $400–$450 in coinsurance before Medigap. A Medigap supplemental policy (Plan G, Plan F) zeroes out the 20% coinsurance, making SCIT effectively free after the deductible. Original Medicare has no network restrictions for SCIT.

The primary driver of dramatic price differences between allergist offices is whether the practice is classified as a freestanding office or a hospital outpatient department (HOPD). Freestanding offices bill only the professional fee under the Medicare Physician Fee Schedule — typically $40–$200 per visit billed. HOPD-classified practices add a separate facility fee under the hospital Outpatient Prospective Payment System, which can multiply the total bill 4–40×. The Kaitlin Johnson case at M Health Fairview in Minneapolis (PBS NewsHour Weekend, 2024) illustrates this: a 40-allergen panel was billed $24,400 at the HOPD, while nearby freestanding clinics quoted $800–$1,827. Secondary drivers include geographic cost-of-living (GPCI) differentials and how aggressively a practice codes E/M visits alongside injection codes. Before your first appointment, ask whether the practice is 'provider-based' and request an expected cost estimate in writing.

California Medi-Cal covers the injection codes (CPT 95115/95117) but explicitly excludes vial preparation as a non-benefit. Per the DHCS Medi-Cal Allergy Manual, Part 2 — Allergy Testing and Desensitization: 'CPT codes 95120 thru 95134 and 95145 thru 95165 for allergen immunotherapy services are non-benefits.' This means the antigen preparation (CPT 95165) is not reimbursed by Medi-Cal. Practices may absorb the preparation cost, require patients to supply antigen from an external source, or decline to offer SCIT to Medi-Cal patients. A Medi-Cal beneficiary who locates a practice willing to absorb the antigen-prep cost can receive injections at $0 patient cost-share for the administration code. This gap disproportionately affects dog-allergic patients who require multi-allergen vials.
