ENT Billing Services for Otolaryngology Practices
In a few weeks, one ENT patient might have an office visit, a nasal endoscopy, a hearing test, allergy testing and sinus surgery. Each has its own coding rules, and they affect each other. The office scope may be bundled into the visit or billed on its own, the surgery may or may not start a global period, and Medicare may need an order before it pays for the audiologist’s tests. Our ENT billing services keep those pieces straight for otolaryngology practices, including those with in-house audiology and allergy.
ENT billing challenges
Office endoscopy and the same-day visit
Diagnostic nasal endoscopy (31231) and flexible laryngoscopy (31575) are common office procedures with zero-day globals. When a scope happens at the same visit as an evaluation, the E/M is billable only if it's significant and separately identifiable, with modifier 25. Payers that see 25 on most scoped visits tend to review them. Diagnostic endoscopy is also generally bundled into a surgical endoscopy of the same area in the same session.
Sinus surgery and laterality
Most endoscopic sinus surgery codes describe one side, so bilateral work needs modifier 50 or RT and LT, depending on the payer. Combined codes, like those covering maxillary and ethmoid work together, have to match exactly what was done on each side. Balloon sinus dilation has its own codes and coverage policies, and many payers want documented failed medical therapy and imaging first.
Global periods
ENT procedures range from zero-day to 90-day globals. Many endoscopic sinus surgery codes carry a zero-day global under Medicare, so later debridements may be billable separately. Tonsillectomy and septoplasty carry 90-day globals that bundle routine follow-up. Modifiers 24, 58, 78 and 79 have to be used correctly for unrelated visits, staged procedures, returns to the OR and new procedures.
Distinct procedure modifiers
Modifier 59 and the more specific XS, XE, XP and XU tell a payer that a service normally bundled under NCCI was distinct. In ENT, XS might fit procedures on different ears or separate sites, but only when the note supports it. Adding 59 or an X modifier just to get past an edit is a well-known audit target.
Audiology
Audiologic tests such as comprehensive audiometry and tympanometry have specific code descriptions, and some can't be billed together on the same day. Medicare generally requires a physician or NPP order for diagnostic audiology, with a limited direct-access exception that uses a specific modifier. Routine hearing exams and hearing aids aren't covered by Medicare, though some commercial and Medicare Advantage plans offer hearing aid benefits through vendors.
Allergy testing and immunotherapy
Skin tests are billed per test, so units have to match the number documented. Immunotherapy separates antigen preparation from injections, and payers define a billable dose differently. Medicare's dose definition doesn't always match how a practice mixes vials. Sinus surgery, balloon dilation, CT imaging and hearing implants also commonly need prior authorization.
Our Services
How Salyx RCM supports ENT practices
Eligibility and authorization
Benefits are checked and prior authorizations for surgery, imaging and other services are submitted and tracked as part of our intake and eligibility work.
Coding review
Endoscopy, surgical, audiology and allergy coding, along with units, laterality and modifiers, are checked against the operative and procedure notes by certified coders on our coding team.
Claim submission
NCCI, MUE and global period edits are scrubbed before any claim goes out.
Payment posting
We post by provider and service line and flag bilateral and multiple-procedure reductions that don't match payer rules.
Denials and appeals
Modifier, bundling, medical necessity and authorization denials are worked, and appeals prepared, by our denial management staff.
Credentialing
Otolaryngologists, audiologists and advanced practice providers are enrolled with your payers through our credentialing service.
Patient balances
Surgical deductibles and allergy treatment balances are explained on clear statements.
Reporting
Reports show denials by reason and service line, open authorizations and AR by payer.
Your EHR
We work in systems like ModMed, athenahealth, eClinicalWorks and NextGen, and others. Operative notes, audiograms and allergy records are reviewed in the EHR your practice already uses, so nothing has to be exported or entered twice.
How It Works
Our process
1. Discovery call
We review your procedure mix, audiology and allergy services, payers and software.
2. Claim sample review
Recent claims are checked for modifier, bundling and global period patterns.
3. Onboarding
A Business Associate Agreement and HIPAA-compliant access come first, then checklists for scopes, surgeries and allergy billing.
4. Daily operations
Verifications, authorizations, coding review, claims, posting and follow-up run on an agreed schedule.
5. Regular review
Denials, AR and authorization turnaround are reviewed with your team.

Frequently Asked Questions
Questions we hear from otolaryngology practices.
1. When can we bill an E/M visit with a nasal endoscopy?
When the visit is significant and separately identifiable from the decision to scope and the scope itself. A new problem with a full workup may qualify, while a brief exam that leads straight to the scope usually doesn’t. We check the note before adding modifier 25.
2. Do you bill bilateral sinus procedures correctly?
Yes. Bilateral procedures are reported with modifier 50 or RT and LT, according to each payer’s rules, and payments are checked against bilateral payment rules.
3. Can you bill audiology services?
Yes. Audiology tests are billed under the audiologist or supervising provider as each payer requires, and Medicare claims are checked for an order or direct-access eligibility.
4. How do you handle allergy immunotherapy billing?
Antigen preparation and injections are billed separately, using each payer’s dose definition, with units matched to the mixing and administration records.
5. Do you track global periods after ENT surgery?
Yes. Each procedure’s global period is tracked, and visits and procedures during that time are reviewed for the correct modifier or bundling, so included care isn’t billed and separate services aren’t missed.
