Allergy & Immunology billing · Portland, Oregon, OR
Allergy and immunology billing services in Portland have to master buy-and-bill before anything else, because the city's largest allergy and immunology revenue increasingly rides on high-cost biologics for severe asthma and chronic urticaria rather than on the office visit. 247 Medical Billing Services has run allergy revenue cycles since 2005, and in Portland — an academic hub anchored by OHSU with a broad commercial, Oregon Health Plan, and Medicare-retiree mix across Multnomah County — we build every biologic episode around the three things that decide whether a $30,000-a-year drug pays.
For a severe-asthma or biologic program, the money is won or lost before the drug is ever drawn. Three checks decide the outcome: the HCPCS unit math has to be exact, the discarded-drug modifier has to be on any single-dose vial, and prior authorization has to be confirmed in advance. Miss any one and a single dose can strand tens of thousands of dollars in a denial or a recoupment.
Portland's payer breadth makes benefit routing the first decision. A biologic may run through the medical benefit under one commercial plan and the pharmacy benefit under another, and Oregon Health Plan routes it differently again. We run verification of benefits on every biologic episode, determine the correct medical-versus-pharmacy path, and lock the authorization before administration. The medical billing for allergy and immunology in Portland that we deliver treats the authorization workflow as clinical infrastructure, not paperwork — because in a biologic-heavy practice it is the difference between a solvent program and one carrying six figures in aged receivables.
Biologics are only part of the book. Skin testing pays per individual test within each payer's annual cap, antigen preparation is billed from the mixing log at one cc per dose, and the prep and administration codes are always separate lines. The injection line is billed once regardless of how many injections a patient receives that day.
| Allergy service (Portland) | Code family | What drives correct payment |
|---|---|---|
| Biologic administration | 96372 / J-code | JW/JZ on single-dose vials; prior auth before administration |
| Percutaneous skin testing | 95004 | Units = number of individual tests, within annual cap |
| Intradermal testing | 95024 | Per-test units; document each site, respect MUE limits |
| Antigen prep, single antigen | 95165 | One cc = one dose; ten billable doses per vial (Medicare) |
| Venom immunotherapy prep | 95145–95149 | Coded by number of venoms, not by vial |
| Immunotherapy injection | 95115 / 95117 | 95117 billed once for two-or-more injections |
| Same-day office visit | 99214 + modifier 25 | Only for a separate, documented E/M service |
Codes live in the claim, not the marketing — but exact unit and drug math is the entire job. The prep-versus-administration split is where generalist billers most often stumble: they merge the antigen line with the injection line, or they multiply the injection code by the number of shots given, and both mistakes produce denials. Venom immunotherapy adds a further trap, since it is coded by the number of venoms rather than by vial, and a wrong count changes the payment outright. Our coders reconcile every one of these elements against the clinical note and the mixing log before a claim is released, so the practice collects the full, defensible value of each encounter rather than a diminished or denied version of it.
Practices choose to outsource allergy billing when biologic authorization volume, benefit-routing complexity, and testing-cap tracking outgrow what in-house staff can manage without costly errors. Outsourcing allergy and immunology billing to a specialty team puts the discarded-drug math, the authorization workflow, and the mixing-log audit with people who do only this work. As a billing company and full-service billing services company with AAPC- and AHIMA-certified coders, HBMA membership, and HIPAA and SOC 2 Type II compliance, we bring 20-plus years of allergy revenue-cycle experience and 98% client retention.
A professional partner should tighten your grip on your numbers, not loosen it. Every Portland practice gets a dedicated account manager and a free 360-degree dashboard showing clean-claim rate, days in A/R under 25, and denial recovery in real time, with claims submitted within 24 hours. As a medical billing services company, we run eligibility, coding, and denial management as one connected pipeline. For a biologic-heavy Portland program, the decision to outsource allergy and immunology billing in Portland usually turns on whether clinical staff should be spending their days chasing payer authorizations or treating patients. Allergy and immunology billing services outsourcing in Portland frees that clinical time while tightening the revenue cycle. It also gives a growing program the reporting it needs to plan: when the dashboard shows clean-claim rate, A/R days, and denial recovery in real time, a practice can see the effect of adding a biologic or a second infusion day before the quarter closes rather than after.

The single antigen-preparation unit is the most-audited line in the specialty, and dosing by clinical judgment instead of the mixing log invites recoupment and False Claims Act exposure. In a biologic-heavy market like Portland, the largest recurring loss is usually a high-cost drug denied for a missing authorization or discarded-drug modifier.

Each denial carries a different financial signature: an antigen over-unit error can open a retrospective audit reaching back months, a biologic denial can cost more than a month of visits, and an underpaid skin panel bleeds quietly until a revenue review catches it. We prioritize the front-end review around that risk, which is why our practices hold a 99% first-pass clean-claim rate, roughly 99% net collection, up to 40% fewer denials, and up to 90% recovery on the appeals we work.
Portland's academic and metro character gives it one of the most varied payer landscapes in the state. OHSU and its affiliated programs draw complex immunology and severe-asthma referrals; commercial employer plans cover much of the downtown and westside workforce; Oregon Health Plan members are enrolled through a Coordinated Care Organization (CCO), primarily Health Share of Oregon in Multnomah County, with the Oregon Health Authority (OHA) prioritized list governing coverage; and a large Medicare-retiree population routes through Noridian (Jurisdiction F). Each of those carries its own testing caps, authorization rules, and biologic policies.
That breadth is exactly why a single generic setup fails here. A biologic that pays cleanly under one commercial PPO may need a different authorization path under OHP and a different one again under Medicare. Working with an allergy and immunology billing services provider in Portland that reads these distinctions — and reconciles antigen units, injection lines, and modifier 25 against each payer's rules — keeps a diverse book clean rather than leaking revenue across the seams between plans.
We support solo and group allergists and immunologists, pediatric and adult allergy practices, high-volume skin-testing and shot clinics, immunotherapy clinics billing incident-to, severe-asthma and biologic infusion programs, and food-allergy and oral immunotherapy programs across Portland and Multnomah County. Whether you run a downtown immunology group heavy on biologic starts, a pediatric allergy practice fielding environmental and food-allergy volume, or a shot clinic billing incident-to, your claims are handled by coders who know allergy rules rather than a generalist pool.
Each of these practice types carries its own documentation and supervision requirements. Incident-to shot clinics need airtight supervision records and unit documentation to survive an audit; oral-immunotherapy and food-allergy programs have to route non-covered components to patient-pay correctly; biologic infusion programs live on pre-service authorization and exact HCPCS math. We build the onboarding around whichever of these describes your practice, integrate with your EHR and clearinghouse so nothing is re-keyed, and keep the same specialty coders on your account so the institutional knowledge does not reset every time your staff turns over.
A Portland allergy practice keeps more of what it earns when every claim is coded, scrubbed, and filed within 24 hours across one of the state's most varied payer books. Our medical billing for allergy and immunology in Portland runs the full cycle for OHSU-referred commercial plans, Oregon Health Plan members enrolled through Health Share of Oregon, and the Medicare-retiree population routing through Noridian Jurisdiction F — reconciling antigen units, injection lines, and biologic authorizations against each payer's own rules before a claim is released. The result is a 99% first-pass clean-claim rate and days in A/R held under 25, so a biologic-heavy Multnomah County program does not carry six figures in aged receivables. If revenue is leaking across the seams between plans, request a revenue review and we will show you where.

Outsourcing Allergy & Immunology Billing Services — the codes, unit rules and denials nationally, without the local layer.
We confirm prior authorization before administration, determine whether the drug routes through the medical or pharmacy benefit, and apply JW or JZ discarded-drug modifiers on single-dose vials. Those three checks are what separate a paid biologic claim from a five-figure denial.
We reconcile every antigen line to the mixing log, apply the one-cc-per-dose and ten-dose-per-vial rules, code venom immunotherapy by venom count, and never bill by clinical judgment. That discipline holds our first-pass clean-claim rate at 99%.
