Medical Billing for Allergy & Immunology Practices

Allergy & Immunology Billing That Pays What You Earn

Allergy and immunology billing requires specialty expertise in skin testing coding, allergen immunotherapy preparation billing, subcutaneous and sublingual immunotherapy injection billing, and the prior authorization process for biologic agents like dupilumab and omalizumab. Skin testing codes are billed per test with payer-specific unit limits, and immunotherapy vial preparation (95165) must be documented by antigen count. 360Solutions provides allergy billing specialists who maximize testing revenue, manage immunotherapy program billing, and navigate biologic auth with precision.

Where Allergy & Immunology Practices Lose Revenue

These are the coding and billing pitfalls that cost allergy & immunology practices the most — and where our specialised billers add the most value.

Allergy Skin Testing Coding

Percutaneous (95004) and intracutaneous (95024/95044) skin testing codes are billed per test. Most payers allow up to 70 or more tests per encounter, but unit limits vary. Undercounting tests billed — or exceeding payer limits — both cost the practice money.

Immunotherapy Vial Preparation

Allergen preparation (95165) is billed per dose for multi-dose vials, not per vial. Many practices bill one unit per vial instead of per dose, significantly undercoding their preparation revenue. Accurate antigen count documentation is required for audit defense.

SCIT & SLIT Injection Billing

Subcutaneous immunotherapy injections (95115 for single antigen; 95117 for multiple antigens) and sublingual drops/tablets each have specific codes. Practices frequently mismatch the injection code to the vial type or miss the supervision requirement documentation.

Biologic Prior Auth

Dupilumab (Dupixent) for asthma, eczema, and CRSwNP, and omalizumab (Xolair) for allergic asthma and urticaria, require prior auth with IgE levels, skin test results, and failed conventional therapy documentation. We manage the full auth lifecycle for every biologic.

95004 / 95024
Allergy skin testing — percutaneous / intracutaneous — per test

Allergen immunotherapy vial preparation — per dose / single-dose vials
95115 / 95117
Allergy injection — single antigen / multiple antigens — office visit

Food/drug/insect challenge testing — initial and additional 1-hour periods

Allergen-specific IgE antibody testing — per allergen — serum RAST
Denial Intelligence

Common Denial Patterns

Knowing these before submission is the difference between a 60% and a 96% first-pass rate.

Skin testing units exceed payer maximum per date of service

Immunotherapy vial preparation billed per vial rather than per dose (95165)

Injection code mismatch — single antigen code used for multi-antigen vial

Biologic auth obtained for wrong indication (asthma vs. CRSwNP vs. atopic dermatitis)

Scratch testing and intradermal testing billed on same date beyond payer limits

Allergy & Immunology Billing FAQ

Questions From Allergy & Immunology Practices

We document the number of doses in each custom vial and bill one unit of 95165 per dose, not per vial. For a 10-dose vial, we bill 10 units. This is consistent with CPT coding guidelines and maximizes legitimate preparation revenue.
Yes. Injection codes (95115/95117) require physician or qualified practitioner supervision. We bill under the correct supervising provider NPI, document the supervision level, and manage any separate billing for the nurse visit component where applicable.
Each covered indication (moderate-to-severe atopic dermatitis, asthma, CRSwNP, prurigo nodularis) has distinct auth criteria. We maintain separate auth templates per indication and submit the correct diagnostic evidence and failed therapy documentation for each.
Yes. Food challenge (95076/95079) and drug/insect challenge testing are billed per hour of testing with documentation of patient monitoring and physician presence. These extended testing codes require specific documentation — we build the billing workflow around the clinical protocol.
