Otolaryngology billing and accounts receivable

Otolaryngology runs office endoscopy, audiology and operating-room work off one schedule — nasal endoscopy, laryngoscopy and tympanostomy tubes alongside sinus surgery, septoplasty and tonsillectomy. Most of that sits inside payer medical policy, so payment turns less on the operation itself than on what the chart proves about failed treatment, imaging and laterality.

Where the money leaks in otolaryngology

These are the recurring denial reasons in this specialty. They are not exotic. They are the ordinary ones that go unworked because the person who could fix them is at the front desk answering a phone.

• Endoscopic sinus surgery denied because the chart never pulls the failed medical management together — the drug trials, their dates and imaging findings sit in separate notes or nowhere.
• Septoplasty denied as not medically necessary because the note records the deviated septum but never ties it to the obstruction it causes or the conservative treatment tried first.
• The operative note does not state which sinuses were entered on which side, so the sinus surgery lines are bundled together or only one side is allowed.
• Office nasal endoscopy or flexible laryngoscopy billed with a visit the same day, where the note does not separately support the scope findings and the evaluation that prompted it.
• Tonsillectomy or adenoidectomy denied because the recurrent infection episodes, or the obstructive sleep-disordered breathing findings, are not documented the way the policy asks.
• Audiometric testing denied as a routine screen because the order carries no medical reason, and hearing aid balances left sitting because the benefit was never checked before dispensing.

What a seat does about it

One trained person works your queue from the difficult end. Every call is logged with the payer reference number and the outcome, so an appeal can quote what was said rather than start again. Denials are categorised, which is how the same reason stops coming back next month. On Friday you get it in writing.

The roles that matter most in this specialty are AR calling and denials at $1,700, prior authorization at $1,900, and certified coding at $2,500.

The codes those turn into

Each of these is a denial code you are likely to meet working otolaryngology, matched to the problem above it in your own words. The route back to payment differs by code, so a queue sorted by recovery route clears faster than one sorted by date.

• CO-50 — Not deemed medically necessary
  The payer does not accept that the documentation supports the service. This is a clinical argument, not a clerical one.
  Recovered by being appealed with clinical documentation. Matched from: “Endoscopic sinus surgery denied because the chart never pulls the failed medical management together — the drug trials, their dates and imaging findings sit in separate notes or nowhere.”
• CO-252 — Additional documentation required
  The payer will not decide until it sees paperwork. Nothing happens until it arrives.
  Recovered by being answered with the document the payer names. Matched from: “Endoscopic sinus surgery denied because the chart never pulls the failed medical management together — the drug trials, their dates and imaging findings sit in separate notes or nowhere.”
• CO-198 — Authorization limit exceeded
  An authorization exists. The problem is that you went past what it allowed — more units, more visits, or a longer date range than was approved.
  Recovered by being answered with the document the payer names. Matched from: “Septoplasty denied as not medically necessary because the note records the deviated septum but never ties it to the obstruction it causes or the conservative treatment tried first.”
• CO-45 — Charge exceeds the fee schedule
  A contractual write-off rather than a denial. It only becomes a problem when the allowed amount is wrong.
  Recovered by being checked against the contract before any work is done. Matched from: “The operative note does not state which sinuses were entered on which side, so the sinus surgery lines are bundled together or only one side is allowed.”
• CO-226 — Requested information not supplied
  The payer asked you for something, and either nothing arrived or what arrived did not answer the question.
  Recovered by being answered with the document the payer names. Matched from: “The operative note does not state which sinuses were entered on which side, so the sinus surgery lines are bundled together or only one side is allowed.”
• CO-227 — Patient did not supply information
  The payer asked the patient for something — very often about other insurance or an accident — and did not get it.
  Recovered by being answered with the document the payer names. Matched from: “Office nasal endoscopy or flexible laryngoscopy billed with a visit the same day, where the note does not separately support the scope findings and the evaluation that prompted it.”

Working a denied claim costs $57.23 per denied claim in administrative time (source), and about about 90% of initially denied claims are eventually paid. Most of what sits in a otolaryngology AR bucket is not lost money. It is money waiting for somebody with the hours to make the call.
