TL;DR: Aetna, a CVS Health company, modified CPB 0418 governing myringotomy and tympanostomy tube insertion, effective September 26, 2025. Here's what billing teams need to know before submitting claims under CPT 69420, 69421, 69433, 69436, and related codes.
The update to this Aetna myringotomy and tympanostomy tube coverage policy tightens and clarifies medical necessity criteria across several indications—including explicit thresholds for otitis media with effusion, recurrent acute otitis media, and balloon dilation of the Eustachian tube (BDET). If your practice bills CPT 69705 or 69706 for BDET, or CPT 69433 and 69436 for tympanostomy tube insertion, this policy directly affects your prior authorization requirements and claim denial risk.

Aetna Myringotomy and Tympanostomy Tube Coverage Criteria and Medical Necessity Requirements 2025
The real issue with CPB 0418 is precision. Aetna's updated coverage policy does not give you wiggle room—each indication has a specific threshold, and falling short of that threshold means a denial.
Tympanostomy tube insertion (CPT 69433, 69436) is covered for otitis media with effusion when the effusion has lasted three months or longer AND the patient has bilateral hearing impairment of 20 dB hearing threshold level or worse in both ears. Both conditions must be present. One without the other won't clear the medical necessity bar.
For recurrent acute otitis media, the threshold is more than three episodes in six months, or more than four episodes in 12 months. Document those episode dates in the chart. Aetna will look for them.
Myringotomy (CPT 69420, 69421) for severe otalgia in acute otitis media is covered—but only the myringotomy, not tube insertion. Know the difference at charge capture.
For diagnostic tympanocentesis and myringotomy to obtain middle ear cultures, the indication must be clear: antimicrobial therapy failure, immunocompromised status, or neonatal presentation. These cases support the medical necessity threshold, but they require documentation of the failed therapy or compromised immune status before you bill.
Balloon dilation of the Eustachian tube (BDET, CPT 69705 and 69706) has a two-track coverage policy—one for ages 8–17, one for adults 18 and older. The pediatric criteria require both chronic otitis media with effusion from inflammatory pathology AND documented failure of at least one prior surgical intervention for obstructive Eustachian tube dysfunction. Both criteria. No exceptions.
Adult BDET criteria require a diagnosis of chronic Eustachian tube dysfunction with symptoms lasting three months or longer that significantly affect quality of life or functional health status. On top of that, Aetna requires a tympanogram type B or C—or, if the patient has had prior tympanostomy tubes, documented symptom improvement while those tubes were patent. And the patient must have none of the listed contraindications: carotid abnormalities in the skull base, nasopharyngeal or skull base neoplasm, patulous Eustachian tube, or untreated allergic rhinitis, rhinosinusitis, or laryngopharyngeal reflux.
That contraindication list is where claims will fall apart. If you don't document the absence of those conditions, Aetna has grounds to deny on medical necessity alone.
Shim placement for patulous Eustachian tube management is covered. So is BDET for autophony due to patulous Eustachian tube under the tympanostomy criteria—but BDET specifically is excluded for patulous Eustachian tube (that's a contraindication for BDET, not for tube insertion). Don't mix those up.
Reimbursement under this policy is contingent on meeting every applicable criterion. Partial documentation is the same as no documentation when Aetna's utilization review team is looking at a claim.
Aetna Myringotomy and Tympanostomy Tube Exclusions and Non-Covered Indications
Two explicit non-covered indications appear in CPB 0418. Both apply specifically to children.
Tympanostomy tube insertion is not covered for children with a single episode of otitis media with effusion lasting less than three months. A single short-duration OME episode doesn't meet the bar—full stop.
Tympanostomy tube insertion is also not covered for children with recurrent acute otitis media who don't have middle ear effusion in either ear at the time of assessment. Timing matters. If you assess the child on a day when there's no active effusion, the criteria aren't met that day. Document accordingly.
The automated tube delivery system covered by code 0583T is listed as related to EarPopper and trans-tympanic balloon dilation. Verify Aetna plan-level coverage for 0583T separately—it carries a non-standard code designation and coverage may vary by plan.

Aetna Myringotomy and Tympanostomy Tube Billing Guidelines and Action Items 2025
These are the steps your billing and clinical teams need to take before the September 26, 2025 effective date.
| # | Action Item |
|---|---|
| 1 | Audit all pending BDET authorizations before September 26, 2025. Check every open prior authorization for CPT 69705 and 69706. Confirm the supporting documentation meets the updated two-track criteria—pediatric cases need documented prior surgical failure, and adult cases need a tympanogram type B or C on file plus explicit exclusion of all four contraindication categories. |
| 2 | Update intake templates for recurrent AOM cases. Your clinical documentation needs to capture episode dates precisely. "Multiple ear infections" won't cut it. You need a dated list showing more than three episodes in six months or more than four in 12 months for tympanostomy tube billing to hold up. |
| 3 | Separate myringotomy from tube insertion in charge capture. When the indication is severe otalgia in acute otitis media, bill CPT 69420 or 69421—not 69433 or 69436. Mixing these codes on the same claim without a separate indication for tube insertion invites a denial. |
| 4 | Document bilateral audiogram results for OME cases. Aetna's coverage policy for tympanostomy tubes in OME requires bilateral hearing impairment at 20 dB or worse in both ears. A chart note saying "hearing affected" is not sufficient. You need the audiogram on file before you submit the claim. |
| 5 | Flag 0583T claims for manual review. CPT 0583T for automated tube delivery is grouped separately in CPB 0418. Coverage may not follow the same path as 69433 or 69436. Verify plan-level coverage before submitting 0583T claims to avoid a claim denial on a procedural basis rather than a medical necessity basis. |
| 6 | Train your prior authorization team on the BDET contraindication checklist. The four contraindications for BDET—carotid abnormalities, nasopharyngeal or skull base neoplasm, patulous Eustachian tube, and untreated allergic rhinitis/rhinosinusitis/laryngopharyngeal reflux—must be explicitly addressed in the authorization request. Omitting any one of them gives Aetna a clean reason to deny. If you're not sure how to structure that documentation, talk to your compliance officer before the effective date. |
| 7 | Confirm ICD-10 code pairing for each indication. The policy covers 320 ICD-10-CM codes. Your diagnosis code on the claim must map directly to a supported indication. A mismatch between the procedure code and the diagnosis code is a fast path to a denial, even when the clinical case is solid. |

Other CPT Codes Referenced in CPB 0418
CPB 0418 also references CPT codes 31000–31070 (incision and excision of accessory sinuses) as related codes. These are not primary tympanostomy tube billing codes—they appear in the broader policy context. Verify specific coverage indications for any sinus-related procedures with your Aetna provider representative.
Key ICD-10-CM Diagnosis Codes
The policy references 320 ICD-10-CM codes total. The provided data does not include the full list. Pull the complete ICD-10-CM code set directly from CPB 0418 at the Aetna provider portal before finalizing your claim mapping. Submitting a claim under a diagnosis code not included in Aetna's covered list for CPB 0418 will generate a denial regardless of procedure code accuracy.
