Allergy and Immunology Billing Services in Boulder, Colorado

The dose code is the most-audited service in the entire specialty, and Boulder's commercial payers are as aggressive on recoupment as Medicare. When a practice doses by clinical judgment instead of the mixing log, every claim carries recoupment and False Claims Act exposure. We remove that risk first, because it is the single largest source of takebacks for immunotherapy practices.

The second-largest leak is quieter: skin panels billed as one unit instead of per test. It never triggers a denial — the claim simply pays less than it should — so it goes unnoticed for months while a high-volume testing clinic quietly loses thousands. We audit for that underpayment pattern on day one, recount to the payer cap, and where the window allows, rework the affected claims. Denials you can see; underpayments you have to hunt for, and hunting for them is exactly what a specialty billing partner is for.

Allergists are not paid on the office visit — they are paid on unit counting and buy-and-bill, and Boulder's payer mix makes both unforgiving. Skin and intradermal testing is reported per individual test, with units tied to the number of tests and held inside each payer's annual cap and MUE. Bill a large aeroallergen panel as one unit and you underpay yourself across an entire allergy season; exceed a commercial plan's cap and the overage is denied outright. Medical billing for allergy and immunology in Boulder is the discipline of counting each test correctly and proving it.

Buy-and-bill is where the largest dollars ride. Biologics for severe asthma and chronic urticaria can run past $30,000 a year per patient, and three things decide whether they pay: exact HCPCS unit math, the JW or JZ discarded-drug modifier on single-dose vials, and a prior authorization confirmed before the drug is administered. Miss the auth or fumble the unit math and a single denial can erase a month of clinic margin. We also keep prep and administration properly split — the antigen line billed only when your practice prepared the vial, the administration code billed once for two or more injections and never multiplied — and we screen non-covered testing such as large IgG food-sensitivity panels to ABN or patient-pay before they ever post as a claim. Modifier 25 goes on a distinct, documented same-day E/M and nowhere else.

We support solo and group allergists across Boulder County, pediatric and adult allergy practices near Foothills Hospital, immunology clinics serving the CU Boulder population, and high-volume skin-testing and shot clinics that bill immunotherapy incident-to. We also work with severe-asthma and biologic infusion programs and food-allergy and oral immunotherapy (OIT) programs whose non-covered testing must be screened before it hits a claim. Each of these fails differently without specialty billing: a shot clinic loses money on under-counted panels, a biologic program loses far more on one denied drug, and an OIT practice bleeds on food testing billed to the wrong party. We tune the workflow to the failure mode that actually threatens your revenue rather than running one template across every allergist in the county.

Practice size does not change the discipline, only the scale. A single-provider allergist in Boulder needs the same mixing-log reconciliation, the same per-test counting, and the same biologic auth checks as a multi-site group reaching into Longmont and Louisville — the difference is volume, and our process scales cleanly across both. We also coordinate the overlapping asthma and buy-and-bill work that Boulder allergists share with pulmonology and immunology colleagues, so a patient's biologic does not fall between two billing systems. The result is a single, accountable revenue-cycle partner rather than a patchwork of point fixes.
