Allergy & Immunology billing · Hillsboro, Oregon, OR
Allergy and immunology billing services in Hillsboro operate in one of Oregon's most commercially insured markets — the Washington County tech corridor known as the Silicon Forest, where large employers like Intel anchor a younger, PPO-heavy workforce alongside a growing Oregon Health Plan population. 247 Medical Billing Services has managed allergy revenue cycles since 2005, and in Hillsboro we tune every workflow to a payer mix that leans commercial, where testing caps, prior-authorization rules, and biologic benefit routing vary sharply from plan to plan.
We support the full range of allergy and immunology practices across Hillsboro and Washington County: 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.
Each of those bills differently. A pediatric allergy clinic serving families near the Orenco Station and Tanasbourne neighborhoods runs high skin-testing and environmental-allergy volume against a mix of commercial and OHP coverage. An adult immunology group treating the tech workforce carries more employer-PPO biologic starts, where prior authorization and specialty-pharmacy routing decide payment. A dedicated shot clinic billing incident-to needs airtight supervision and unit documentation, while an oral-immunotherapy program for food allergy has to route non-covered components correctly. As an allergy and immunology billing services provider in Hillsboro, we configure each practice's setup around its own case mix rather than forcing one template onto all of them.
That configuration is not cosmetic. The fee schedules, the authorization pathways, and the documentation triggers differ enough between a high-volume pediatric skin-testing clinic and an adult biologic infusion program that a single generic setup would leave money on the table for both. We map each payer's testing caps and prior-auth rules into the workflow so the front desk and the clinical team are never guessing whether a service is covered before it is delivered. For a practice adding a new biologic to its formulary or opening a second immunotherapy day, that mapping is what lets billing scale on day one instead of lagging a quarter behind.
The office visit is rarely where the revenue is. Skin testing pays per individual test — units set to the number of tests inside each payer's annual cap — and antigen preparation is billed from the mixing log at one cc per dose. The prep code and the administration code are separate services, and the injection line is billed once no matter how many injections are given. Biologics for severe asthma or chronic urticaria pay only when the HCPCS unit math is exact and prior authorization is confirmed before the drug is drawn.
| Allergy service (Hillsboro) | Code family | What drives correct payment |
|---|---|---|
| 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 |
| Biologic administration | 96372 / J-code | JW/JZ on single-dose vials; prior auth before administration |
| Same-day office visit | 99214 + modifier 25 | Only for a separate, documented E/M service |
Codes belong in the claim, never in the sales copy — but counting them correctly is the whole job of allergy billing. The most common way a generalist biller loses money here is by collapsing a multi-test skin panel into a single unit; the claim pays, but at a fraction of what the practice earned, and the shortfall rarely surfaces until someone runs a revenue analysis. The mirror-image error is multiplying the injection administration code by the number of shots given, which produces an outright denial. Our coders set testing units to the exact number of individual tests, bill the injection line once for two-or-more injections, and keep the antigen-prep line separate from the administration line every time.
Hillsboro's commercial skew changes the shape of the work. Where a Medicaid-heavy market lives and dies on eligibility, a PPO-heavy market like Washington County lives and dies on prior authorization and benefit routing — especially for high-cost biologics. The medical billing for allergy and immunology in Hillsboro that we run puts verification of benefits and prior authorization at the front of every biologic and immunotherapy episode, confirming whether a drug routes through the medical or the pharmacy benefit before it is ever administered.
The local Oregon Health Plan population still matters. OHP members here are enrolled through a Coordinated Care Organization (CCO) — Health Share of Oregon in the tri-county region — with the Oregon Health Authority (OHA) setting the prioritized list that governs coverage, and Medicare routed through Noridian (Jurisdiction F). We verify each of those payers against its own testing caps and antigen-prep policies. A biologic that pays cleanly under a commercial PPO may need an entirely different authorization path under OHP, and treating them the same is how revenue leaks. Working with an allergy and immunology billing company in Hillsboro that reads these distinctions keeps both sides of the payer mix clean.

The single antigen-preparation unit is the most-audited line in the specialty, and clinical-judgment dosing that ignores the mixing log invites recoupment and False Claims Act exposure. In a commercial market, the bigger recurring loss is often a biologic denied for a missing authorization or discarded-drug modifier — a single dose can strand tens of thousands of dollars.

Modifier 25 deserves particular care in a commercial market. It belongs only on a distinct, documented same-day evaluation and management service, never on a routine shot visit, and commercial payers deny or claw back unsupported use aggressively. We review the clinical note before the modifier is applied, so a legitimate separate E/M is paid and an unsupported one is never billed in the first place. Non-covered testing, such as large IgG food-sensitivity panels, is screened to an advance beneficiary notice and patient-pay before it can become a payer rejection.
That front-end discipline is why our practices hold 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 the appeals we work. In a PPO-heavy market where a single biologic denial dwarfs a month of visit revenue, that prevention-first posture is worth far more than any after-the-fact appeals volume.
Practices choose to outsource allergy billing when prior-authorization volume, plan-by-plan testing caps, and biologic benefit routing outgrow what in-house staff can track without errors. Outsourcing allergy and immunology billing to a specialty team means the mixing-log audit, the authorization workflow, and the discarded-drug math sit with people who do only this. 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 work and 98% client retention.
A professional partner should make you closer to your numbers, not further from them. Every Hillsboro practice gets a dedicated account manager and a free 360-degree dashboard showing clean-claim rate, A/R days, and denial recovery in real time, with claims out the door within 24 hours. As a medical billing services company, we run eligibility, coding, and denial management as one connected workflow. For a growing tech-corridor practice, the decision to outsource allergy and immunology billing in Hillsboro usually comes down to whether staff time is better spent on payer authorizations or on patients.

Medical Billing for Allergy & Immunology — the codes, unit rules and denials nationally, without the local layer.

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 is why our first-pass clean-claim rate holds at 99%.
Yes. We verify OHP eligibility and CCO assignment through Health Share of Oregon, confirm prioritized-list coverage, and manage commercial and Medicare claims in parallel, each against its own testing caps and authorization rules.

Yes. Large IgG food-sensitivity panels and similar non-covered tests are flagged and moved to an advance beneficiary notice and patient-pay before submission, so they never come back as an avoidable payer denial that has to be reworked or written off later.
