Allergy and Immunology Medical Billing Services

Testing, antigen preparation and immunotherapy billing with unit-level accuracy for allergy practices and immunology clinics.

Allergy billing turns on units and preparation records: a practice can test carefully, prepare antigen correctly and deliver immunotherapy for years — and still lose money if the doses prepared, the doses administered and the doses billed drift apart. Elite Bill Care's allergy and immunology medical billing services are built around reconciling those three things, so the revenue from a long-term immunotherapy panel is as reliable as the care itself.

Allergy and immunology billing specifics

Testing vs. preparation separation — allergy testing and antigen preparation are distinct services with distinct coding logic. We bill each for what it is: the testing performed on the patient, and the preparation and supply of antigen by the practice, without conflating the two or double-reporting either.
Antigen preparation unit accuracy — preparation is billed in doses, and the unit count is where allergy claims succeed or fail audits. We calculate units from your preparation records — vial sizes, dilutions and doses prepared — and verify them before submission, so a math error is not multiplied across a patient's entire course of therapy.
Build-up and maintenance phase billing — immunotherapy administration is reported differently during build-up and maintenance, and by the number of injections given at each visit. Phase changes are tracked per patient so administration coding follows the treatment plan, not a default.
Supervision and documentation rules — preparation and administration are billed in line with the supervision and documentation expectations payers apply to allergy services: who prepared the antigen, who administered it, and the direct supervision in place are documented in the record that supports the claim.
Wastage and vial tracking — single-dose and multi-dose vial handling, expired antigen and wasted doses are reconciled against preparation logs, so units billed never exceed doses actually prepared and available to administer.
Visit and testing integration — evaluation and management visits, pulmonary function testing and challenge testing performed alongside immunotherapy are reviewed for correct bundling and modifier use, so legitimate separate services are paid and bundled ones are not billed twice.

Common allergy and immunology billing challenges

The signature allergy denial is a unit dispute: preparation billed in units the payer recalculates differently, or units that exceed what the preparation record supports, which can turn into a refund demand across hundreds of claims at once. Close behind are administration codes that do not reflect the number of injections given, build-up visits still billed at maintenance logic months after the phase changed, and documentation gaps between the mixing log, the injection record and the claim. Because immunotherapy patients stay on therapy for years, even a small per-claim error compounds into the practice's largest single audit exposure.

How we run it

Preparation logs, injection records and charges are reconciled on a regular cycle for every active immunotherapy patient, so units billed track doses prepared and administered. Phase changes are flagged from the treatment record, testing claims are matched to the documented results that support them, and denials are worked by cause — units, documentation, bundling and medical necessity — with payer-specific unit calculations documented in your file so the same dispute is not re-argued claim by claim. Practices see held or adjusted charges with the reason, the same way they see paid ones.

Benefits of specialized allergy and immunology billing

Immunotherapy is long-cycle revenue: patients build up over months and maintain for years, and billing accuracy compounds the same way errors do — in your favor. Elite Bill Care brings more than 10 years of billing experience, a 98% first-pass clean claim rate and denial management that has reduced denials by up to 30% for the practices we serve. Because our allergy and immunology medical billing services reconcile preparation, administration and claims continuously, unit errors, phase mistakes and unworked denials are found and closed. The result is dependable therapy revenue and a clean audit trail, in all 50 U.S. states.

Software and systems we work with

Our team works inside the major EHR and practice management platforms used by allergy practices — including athenahealth, eClinicalWorks, AdvancedMD, Tebra, DrChrono, Office Ally, CollaborateMD, NextGen, Practice Fusion and TherapyNotes — and takes preparation and injection data from your practice's own logs and systems. All work runs on HIPAA-compliant processes with role-based access to your systems.

Frequently asked questions

How do you calculate antigen preparation units?

Units are calculated from your preparation records: the number of doses prepared, based on vial configuration and dilution, following the payer's definition of a dose. We verify the calculation before claims go out and document it per payer, because payers do not all define a billable dose identically — and the preparation log is the record an auditor will ask for.

Do you bill both allergy testing and immunotherapy?

Yes. We bill the full service line: percutaneous and intracutaneous testing, antigen preparation and supply, build-up and maintenance administration, and related services such as challenge testing. Testing, preparation and administration are kept distinct in coding, which is where generalist billing most often creates denials and audit risk in this specialty.

Can you reconcile our preparation logs with what was billed?

Yes — that reconciliation is a standard part of the service. We compare doses prepared, doses administered and doses billed for each patient panel, correct drift before it becomes a pattern, and report discrepancies to your team. It is the single most effective control against both underbilling and the refund exposure of overbilled units.

Do you work with hospital-based immunology clinics as well as private practices?

Yes. We bill for independent allergy practices, multi-physician groups and hospital-affiliated immunology clinics. The workflow — preparation records, phase tracking, unit verification — is configured for how each setting documents and stores its mixing and administration records.
