Specialty Billing
ENT / Otolaryngology Billing Services
Specialized billing for the full range of otolaryngology — from in-office nasal endoscopy and audiological testing to sinus surgery and head and neck procedures.
ENT Billing Overview
ENT billing combines a high volume of in-office diagnostic and procedural services with complex surgical coding — and navigating the intersection of these two categories requires specialty-specific expertise. Nasal endoscopy performed in the office has its own coding rules that differ from diagnostic nasal endoscopy performed as a standalone procedure. Audiological testing has technical and professional component distinctions. Allergy testing and immunotherapy involve multiple billable components per visit. And functional endoscopic sinus surgery (FESS) requires careful code selection based on which sinuses were addressed and whether the procedure was diagnostic or surgical. At 2 Lee's Billing, we handle ENT billing in all its complexity — ensuring complete capture of office-based procedures, correct surgical coding, and compliant billing for the full scope of otolaryngology practice.

Common ENT Billing Challenges
Nasal Endoscopy Bundling Rules
When a diagnostic nasal endoscopy is performed and finds pathology requiring a surgical intervention during the same session, the diagnostic component may be bundled into the surgical code. Understanding when to bill both vs. only the surgical code requires code-level bundling knowledge.
Audiological Testing TC vs. PC
Hearing testing has a technical component (equipment and administration) and a professional component (interpretation and report). If your practice employs an audiologist and owns the equipment, you bill the global service. If you interpret tests performed by a hospital or outside clinic, you bill only the professional component.
Allergy Testing Component Billing
Allergy skin testing and immunotherapy involve multiple separately billable components — testing codes, antigen preparation, injection codes, and physician supervision. Missing any component or incorrectly bundling them results in underpayment.
Prior Authorization for Sinus Surgery
FESS and related sinus procedures almost universally require prior authorization from commercial payers, with conservative treatment documentation often required as a prerequisite. Missing or incomplete authorization results in high-value claim denials.
FESS Code Selection Complexity
FESS coding requires identification of exactly which sinuses were addressed — maxillary, ethmoid (anterior vs. posterior), frontal, sphenoid — with separate codes for each. Undercoding multi-sinus procedures significantly reduces reimbursement.
ASC vs. Office-Based Procedure Billing
Many ENT procedures can be performed in both office and ASC settings. The billing rules, expected reimbursement, and payer coverage policies differ significantly between settings — and errors in setting designation result in incorrect payment.
How 2 Lee's Billing Supports ENT Practices
Nasal Endoscopy Coding
We review procedure documentation and apply the correct diagnostic or surgical nasal endoscopy codes — including the site-specific and extent-specific distinctions that determine which codes apply.
Audiological Test Billing
We correctly determine whether to bill the global, technical, or professional component for each audiological study based on your practice's ownership of equipment and employment of testing personnel.
Allergy Testing and Immunotherapy Capture
We capture all billable components of allergy testing and immunotherapy visits — testing procedure codes, antigen preparation codes, and injection administration codes — ensuring complete reimbursement for allergy services.
FESS Surgical Coding
We review operative reports for FESS procedures and apply the correct site-specific codes for each sinus addressed — recovering the full value of multi-sinus procedures without undercoding.
Prior Authorization for ENT Procedures
We identify and obtain prior authorizations for scheduled sinus surgery and other ENT procedures — including gathering the conservative treatment documentation that payers frequently require.
Office Procedure Capture
In-office ENT procedures — cerumen removal, nasal cautery, flexible laryngoscopy, ear irrigation — are separately billable and frequently undercaptured. We identify and bill all separately billable office-based services.
