Allergy & Immunology billing · Pasadena, CA
Allergy and immunology billing services in Pasadena serve a San Gabriel Valley market that is older, more commercially insured, and more biologic-heavy than most of Los Angeles County — which changes where the money leaks.
247 Medical Billing Services has run this specialty since 2005, and in a Pasadena practice the revenue turns on exact unit counting and clean buy-and-bill routing far more than on the office visit itself. This page lays out how we bill a Pasadena allergy practice so that testing, immunotherapy, and biologics all pay the first time.
We bill for the full range of foothill allergy practices: solo and group allergists and immunologists, pediatric and adult allergy clinics, high-volume skin-testing and shot rooms, immunotherapy clinics billing incident-to, and — more common in Pasadena than in outlying markets — severe-asthma and biologic infusion programs and food-allergy and oral-immunotherapy programs. Whether you run a single office off Lake Avenue or a multi-provider group taking foothill referrals, our credentialed coders and a dedicated account manager handle the coding your revenue depends on. As an allergy and immunology billing services provider in Pasadena, we scale the team to your test and infusion volume rather than forcing your practice onto a generic template.
The lines below drive the money, and each carries a rule that keeps it clean across commercial payers, Noridian Medicare, L.A. Care, Health Net, and Medi-Cal.
| Service line | Code | What has to be right in Pasadena |
|---|---|---|
| Percutaneous skin testing | 95004 | Units = number of tests; hold to annual cap/MUE |
| Intradermal testing | 95024 | Per-test units; document each site separately |
| Antigen prep, single | 95165 | One cc per dose; 10 doses per multidose vial for Medicare |
| Venom prep | 95145–95149 | Units set by venom count, not by vial |
| Injection, one/two+ | 95115 / 95117 | 95117 once for two or more injections |
| Same-day E/M | 99213–99214, mod 25 | Only on a distinct, documented service |
| Biologic administration | J-code + admin | JW/JZ on single-dose vials; prior auth first |
Allergy is a unit-counting specialty. Skin and intradermal testing is reported per individual test, with the unit count matching the number of tests and staying inside each payer's annual cap and MUE ceiling — never collapsed into a single panel unit, which is the fastest way to underbill a workup by half. Antigen preparation is billed from the mixing log at one cc per dose, with ten billable doses per multidose vial for Medicare, and venom is coded by venom count. Preparation and administration are separate services: the antigen line is billed only when your practice prepared the vial, and administration is reported once for two or more injections rather than multiplied per shot.
Because Pasadena carries a larger biologic caseload, the buy-and-bill discipline matters even more here. For the severe-asthma and chronic-urticaria drugs a foothill practice administers, the HCPCS unit math has to be exact, the discarded-drug modifier has to sit on single-dose vials, and prior authorization has to be confirmed before the dose goes in — with the drug routed through the correct medical-versus-pharmacy benefit for the specific commercial plan or L.A. Care. Modifier 25 belongs only on a distinct, documented same-day evaluation, never on a routine shot, and non-covered testing such as large IgG food-sensitivity panels is screened to an ABN and patient-pay before it is ever submitted. That is the real content of medical billing for allergy and immunology in Pasadena.

The antigen-preparation unit is the line California's Medicare Administrative Contractor, Noridian Healthcare Solutions (Jurisdiction E), scrutinizes most, and dosing from clinical judgment instead of the mixing log is precisely what invites recoupment and False Claims Act exposure — so we tie every unit to the log.
Pasadena's higher commercial share adds a second layer of denial risk that a Medicaid-heavy market does not face as often: commercial carriers apply their own biologic prior-authorization rules, step-therapy requirements, and site-of-care policies that change from plan to plan and quarter to quarter. Verification of benefits on every biologic patient, done before the first dose, is what keeps a five-figure drug from sitting unpaid, and it is the discipline that separates an infusion program that funds itself from one that quietly builds a receivable it may never collect.
A biologic-heavy Pasadena practice rarely has the in-house depth to keep unit-counting, modifier discipline, and buy-and-bill authorizations clean while running a full clinic and infusion schedule. When you outsource allergy and immunology billing in Pasadena to us, a professional team that has coded 95165 and biologic claims for twenty years owns your revenue cycle. We are a HIPAA-compliant, SOC 2 Type II billing services company and an HBMA member, and the numbers behind outsourcing allergy and immunology billing services in Pasadena are concrete: a 99% first-pass clean-claim rate, roughly 99% net collection, days in A/R under 25, up to 40% fewer denials, and up to 90% recovery on denials we appeal. Claims go out within 24 hours, client retention runs 98%, and a free 360° dashboard keeps your revenue transparent.
Choosing an allergy and immunology billing company in Pasadena should come down to specialty depth and transparency, which is what our medical billing services company was built to provide — and why allergy and immunology billing services outsourcing in Pasadena is a sound move for a practice whose margin lives in correctly counted units and correctly routed drugs.
Medical billing for allergy and immunology in Pasadena rewards a team that reads this foothill market correctly: commercial and Medicare-retiree panels around Huntington Hospital and Kaiser's Pasadena footprint, a biologic caseload heavier than most of the county, and a Medi-Cal slice flowing through L.A. Care and Health Net. We verify benefits on every biologic patient before the first dose, tie each antigen unit to the mixing log, and route buy-and-bill drugs to the correct commercial or managed-care benefit under each plan's own step-therapy and site-of-care rules. The payoff for a San Gabriel Valley practice is near 99% net collection, days in A/R under 25, and five-figure infusions that fund themselves. Request a revenue review.
