Specialty Billing
Allergy and Immunology Billing Services
Billing for allergy practices — where revenue is counted in test units and vial doses, and accuracy compounds across thousands of small billable increments.
Allergy billing is unit arithmetic at scale: skin testing billed per test with documented counts, immunotherapy billed across preparation (per vial/dose) and administration (per injection), and multi-year treatment courses whose billing must stay consistent through dose escalations, vial changes, and payer transitions. Biologics for asthma and urticaria add authorization-managed drug billing on top.
Our allergy billing keeps the arithmetic exact: test counts reconciled to documentation, vial preparation billing captured when serum is mixed (not forgotten until injections), administration claims flowing at visit volume, and biologic programs run with per-cycle authorization discipline.
Why Allergy and Immunology Billing Is Complex
Every allergy revenue line is a countable unit that payers can audit against documentation: number of percutaneous and intradermal tests, number of vial-doses prepared, injections given per visit. Undercounting is silent revenue loss; overcounting is audit exposure. Immunotherapy courses spanning years cross plan changes and deductible resets, making eligibility re-verification and patient-cost communication a permanent workflow rather than an intake step.
Common Service Categories We Bill
- Percutaneous and intradermal allergy testing
- Subcutaneous immunotherapy (build-up and maintenance)
- Biologic therapy for asthma and chronic urticaria
- Drug and food challenge procedures
- Pulmonary function testing for asthma management
Common Denial Causes in Allergy and Immunology
- Unit-count edits on testing claims
- Preparation-versus-administration construction errors
- Biologic authorization lapses
- Frequency edits on repeat testing
Documentation Risks to Watch
- Test counts in notes not matching billed units
- Vial preparation records not supporting billed doses
- Challenge procedure time and monitoring documentation thin
Coding Considerations
- Testing codes bill per test with documented counts — the encounter note is the audit defense
- Preparation codes bill per dose-vial under payer-specific unit definitions that genuinely differ
Educational note: Coding and payer information on this page is general educational content, not definitive coding, legal, or reimbursement advice. CPT/ICD-10 rules and payer policies change frequently — verify specifics against current official sources and qualified professionals.
Typical Payer Challenges
- Unit-definition differences between payers on immunotherapy preparation
- Step-therapy on biologics requiring documented conventional-therapy failure
Allergy and Immunology Billing FAQs
How do payers define immunotherapy “doses” differently?
Some payers count a dose as a defined volume increment from the vial; others apply their own maximums per preparation billing. The same mixing session can be worth different billable units under different contracts — so we maintain per-payer unit rules and bill preparation to each payer’s definition, which protects both revenue and audit posture.
Patients quit immunotherapy over surprise bills — can billing help retention?
Significantly. Most “surprise” is January: deductibles reset and the weekly injection suddenly costs money. Re-verifying benefits each plan year, telling patients their new expected cost before the first January visit, and offering payment plans keeps courses — and their clinical benefit — intact.
