About Our Allergy & Immunology Billing Services

Allergy and immunology practices face unique billing challenges that many general billers can’t handle.

Why Allergy & Immunology Billing is Complex

Running an allergy practice means juggling diagnostics, ongoing immunotherapy, and high-cost medications.

Here’s where most practices struggle:

Testing Codes Overlap: CPT codes for allergy testing (95004–95078) are highly detailed and specific, providing a comprehensive overview of the procedure. Incorrect billing for skin prick, patch tests, and intradermal tests can lead to denials.

Immunotherapy Documentation: Insurance carriers require precise logs for vial preparation, dosage, and administration. Missing documentation often triggers audits.

Biologic Medications: Drugs such as Xolair, Dupixent, and Nucala require prior authorizations and accurate J-code billing. Mistakes can result in thousands of dollars in lost reimbursements.

Frequent Denials: Mismatches in modifiers, units, and diagnosis codes cause some practices to face denial rates as high as 30–40%.
