Insurance at Latitude: the two-part answer

Per Latitude's own FAQ, the list runs by region. Northern California: Aetna, Anthem Blue Cross, Blue Shield, Cigna, Health Net, UnitedHealthcare, and select HMOs. Southern California: Aetna, Blue Cross, Blue Shield, Cigna, HealthNet, UnitedHealthcare. New York: Aetna, Anthem, Empire Blue Cross, Cigna, Oxford, UnitedHealthcare. Diagnostics and visits are described as "typically covered" when you are in-network. Lists change without notice, so confirm your specific plan with the clinic and your insurer before relying on this page.

Latitude describes the one-time OIT program fee as a non-covered service but does not publish the amount on its website. Patient reports fill the gap: one Bay Area family wrote they had to pay "over $4,000 for a so-called program fee which they say is definitely not covered by insurance," adding it was "shocking given I did plenty of research"; a New York reviewer put it at over $5,000. Treat the honest figure as a range — $4,000 to $5,000-plus depending on region and year — and get the exact number for your case in writing before enrolling. Payment plans are offered, and the fee is FSA/HSA eligible.

US insurers reimburse discrete billable services — office visits, procedures, lab tests — and a proprietary program fee is none of those. There is also no approved product left to bill against: Palforzia, the only FDA-approved oral immunotherapy, was withdrawn from the US market on July 31, 2026, so all food immunotherapy is now prescribed off-label, at clinics and at-home programs alike. Off-label does not mean unsafe — it is how this entire field operates — but it does mean the core of every program lands on the family. The useful response is not frustration at one clinic but arithmetic at all of them: what exactly is billable, what is not, and what your plan leaves you of the billable part.

Food challenges fall under testing and diagnostics, which Latitude's FAQ describes as typically covered when you are in-network — a genuinely different category from the program fee. They are also one of the strongest things Latitude does: oral food challenges are the gold standard of food allergy diagnosis, and parents on Park Slope Parents specifically praised Latitude's challenges for removing false-positive allergy labels, calling the experience "life-changing." Note that food challenges happen in clinic on every protocol in this market, including for Curex patients. Still run the billing codes past your insurer first, since "typically covered" is not a guarantee for your plan.

Yes to both, per Latitude's FAQ: the program fee is FSA/HSA eligible and payment plans are available. That matters because FSA/HSA dollars are pre-tax, which effectively discounts the fee by your marginal tax rate. If you are planning enrollment for next year, it may be worth timing FSA elections to the fee. Ask for the payment-plan terms in writing alongside the fee itself, so both numbers arrive before you sign rather than after.

Latitude's active treatment runs 6–12 months to maintenance, averaging about 8.4 months, and is followed by lifelong maintenance dosing with long-term care offered. Maintenance visit billing should follow the same in-network logic as other visits, but Latitude does not publish what ongoing care costs, so ask upfront. The question matters across the market: at Food Allergy Institute, families report an annual fee of roughly $4,000 after reaching remission that they describe as not disclosed until they asked very specific questions. Ask every provider — including us — what year three costs, not just year one.

The one FDA-approved food allergy medication is Xolair (omalizumab), approved in February 2024 for ages 1 and up — and being FDA-approved, it is the option insurers are most likely to reimburse. But it does a different job: Xolair reduces reaction severity on accidental exposure and does not desensitize; avoidance continues. In the OUtMATCH trial, 68% of treated patients tolerated at least 600mg of peanut protein versus 6% on placebo, while 17% saw no significant change. Immunotherapy — the only disease-modifying approach, in clinical use for 100+ years — is off-label everywhere since Palforzia's withdrawal. See [the full treatment landscape](/learn/food-allergy-treatment-options) for how these pieces fit together.

Same split, smaller uncovered core. Testing and consultations are often billable to insurance; the compounded sublingual treatment itself is out-of-pocket, because insurers do not reimburse compounded preparations — which are made per-patient from the same FDA-approved allergenic extracts used in allergy shots, though the compounded drops themselves are not an FDA-approved product. Curex's food allergy plan is $199 per month, with environmental allergy plans from $79 per month, and patients can generally save more than $10,000 over the course of treatment versus in-person programs. It is the only fully at-home program — every state, from age 2, video or text visits — and the first choice for families outside the coastal metros, families who move or travel, working parents, adults, and children in sport.

Allergy Associates of La Crosse in Onalaska, Wisconsin — the clinic that has treated food allergy with drops since 1970 and wrote the La Crosse Method protocol — publishes its prices: a first visit in person at a typical $750–850 ($1,000–1,400 for complex cases), rechecks every 3–6 months in person or virtual at about half that, and food allergy drops at about $2.20 a day, patient-pay, over 3–5 years. The drops are compounded, so the same out-of-pocket rule applies as at home; ask the clinic what your plan covers of the visits. It treats infants through adults, explicitly including patients with a history of anaphylaxis or uncontrolled asthma, in person. It is the same kind of treatment as the at-home route, entered through a clinic.
