Allergy & Immunology billing · Daly City, CA
Allergy and Immunology Billing Services in Daly City, California
Allergy and immunology billing in Daly City starts with the line most likely to cost you money: antigen preparation.
At 247 Medical Billing Services, we treat the antigen-prep unit as the audit target it is, because in this specialty a single mis-billed preparation code does more damage than a dozen denied office visits. Daly City allergists sit just south of San Francisco in northern San Mateo County — a dense, diverse, heavily insured market where a large share of patients carry Health Plan of San Mateo Medi-Cal managed care alongside Bay Area commercial plans. Getting the drug and testing math right across that payer mix is the whole job.

Denials in allergy and immunology are not random — they repeat. We lead with them because preventing this short list is where almost all of your recoverable revenue lives, and the antigen-preparation error at the top is the one that can turn into a recoupment demand.

Antigen preparation is billed from a documented mixing log — one cc per dose, ten billable doses per multidose vial for Medicare — and it is the single most-audited line in the specialty. Bill it from clinical judgment and you carry recoupment and False Claims Act exposure; under-report it and you give away margin you earned. Our certified coders reconcile every preparation unit to your log before the claim goes out.

Best Allergy and Immunology Billing Services in Daly City
Skin and intradermal testing is the flip side of the antigen problem. Percutaneous and intradermal tests are reported per individual test, with units matching the number of tests performed and capped at each payer's annual limit and MUE. Practices that arrive from a generalist biller are almost always billing these as one panel unit, and the underpayment goes unnoticed because the claim pays — just for far less than it should. As a medical billing services company built around this specialty, we set your charge capture so units track the antigens actually tested at every visit.
The prep-versus-administration split matters just as much in a busy Daly City shot clinic. The antigen-preparation code and the injection-administration code are separate services; the administration code for two or more injections is billed once per visit, never multiplied by the number of shots; and the antigen line is billed only when your practice prepared the vial. Repeated across a five-day immunotherapy schedule, a small error here compounds into a serious annual leak.

Medical Billing for Allergy and Immunology in Daly City
Buy-and-bill biologics for severe asthma and chronic urticaria carry the highest dollars and the least forgiving denials. Three things decide whether a drug costing tens of thousands per year pays: exact HCPCS unit math, the correct discarded-drug modifier on single-dose vials, and prior authorization confirmed before administration. Miss one and the claim is a full write-off, not a slow payment. We run verification of benefits and prior-auth on every biologic and route each through the correct medical-versus-pharmacy benefit before your clinical staff draws it up — critical in a market where Health Plan of San Mateo, Medicare, and commercial plans each handle the benefit differently.
Modifier 25 is applied only to a genuinely distinct, documented same-day evaluation and management service — never to a routine allergy shot. That discipline keeps your E/M revenue defensible instead of inviting the exact audit that indiscriminate modifier 25 use provokes.

Who We Serve on the Peninsula
