TL;DR: Aetna, a CVS Health company, modified CPB 0265 governing sialorrhea surgical treatments, effective September 26, 2025. Here's what billing teams need to know before submitting claims under CPT codes 42440, 42507, 42509, 42510, 42665, and 69676.
Aetna's sialorrhea coverage policy under CPB 0265 Aetna outlines strict two-part medical necessity criteria that must both be satisfied before any surgical claim gets paid. The policy covers eight specific surgical approaches — from submandibular gland excision to tympanic neurectomy — but only after conservative therapy has failed. If your practice bills for salivary gland surgery or oro-neural procedures, this modification affects your prior authorization checklist and your claim documentation requirements starting September 26, 2025.

Aetna Sialorrhea Coverage Criteria and Medical Necessity Requirements 2025
The Aetna sialorrhea coverage policy under CPB 0265 sets a two-gate medical necessity test. Both criteria must be met. Missing either one is a straight path to claim denial.
Gate 1: The member must have excessive drooling associated with significant morbidity. Aetna defines this as skin maceration, poor oral hygiene, or dehydration. Vague clinical notes about "excessive saliva" won't clear this bar. Your documentation needs to name one of those three specific conditions.
Gate 2: The member must have failed to adequately respond to both appropriate physical therapy and drug therapy. This is a conjunctive requirement — not one or the other. If only pharmacologic treatment was tried, that's not enough. Your records need to show both modalities were attempted and failed.
This two-part test is the core of the coverage policy. It's also where most denials will originate. Sialorrhea billing gets complicated fast when documentation is thin on the conservative treatment history.
The policy doesn't specify which drugs count as "appropriate drug therapy," which gives Aetna some latitude during medical review. Common agents used in practice include anticholinergics like glycopyrrolate and scopolamine, and botulinum toxin injections. If your patient received botulinum toxin as drug therapy and it failed, document that specifically — it's a recognized treatment modality for sialorrhea. Don't assume the reviewer knows what was tried.
Prior authorization requirements are not explicitly stated in the CPB 0265 text, but given the complexity and the step-therapy requirements embedded in the criteria, treat this as a prior auth situation until Aetna confirms otherwise for your specific plan contracts. Surgical procedures for sialorrhea are not routine, and payers apply heightened scrutiny to them. Check with your Aetna provider relations contact for plan-level prior authorization requirements before scheduling surgery.
Reimbursement for these procedures hinges entirely on meeting both criteria. Submit without solid documentation and you're not just risking one denied claim — you're opening your practice to retrospective audit if a pattern emerges.
Aetna Sialorrhea Exclusions and Non-Covered Indications
CPB 0265 explicitly excludes two treatments from coverage under this policy: transoral submandibular ganglion neurectomy and kinesio taping. Aetna considers these not medically necessary for controlling drooling.
The coverage policy groups CPT 36470 (injection of sclerosant, single incompetent vein) and CPT 49185 (sclerotherapy of a fluid collection, percutaneous) under the non-covered category alongside those two treatments. If your team has been billing sclerotherapy approaches for sialorrhea under Aetna, stop. These are not covered under CPB 0265 and will deny.
The policy also lists several CPT codes as "other codes related to the CPB" without covering them outright for this indication. These include CPT 42450 (excision of sublingual gland), CPT 42500 and 42505 (sialodochoplasty), CPT 42550 (injection for sialography), and CPT 70390 (sialography, radiological supervision and interpretation). These codes can appear in the clinical workup, but they don't carry standalone coverage under the sialorrhea surgical indication criteria in CPB 0265.
Coverage Indications at a Glance
| Indication / Procedure | Coverage Status | Relevant Codes | Notes |
|---|---|---|---|
| Excision of submandibular gland | Covered (if criteria met) | CPT 42440, HCPCS D7981 | Requires documented morbidity + failed PT and drug therapy |
| Four-duct ligation (bilateral submandibular + parotid ducts) | Covered (if criteria met) | CPT 42665 | Same two-gate criteria apply |
| Parotid duct diversion, bilateral (Wilke type) | Covered (if criteria met) | CPT 42507 | Same two-gate criteria apply |
| Parotid duct diversion + excision of both submandibular glands | Covered (if criteria met) | CPT 42509 | Most extensive surgical option covered |
| Parotid duct diversion + ligation of both submandibular ducts | Covered (if criteria met) | CPT 42510 | Same two-gate criteria apply |
| Relocation of submandibular ducts, with or without sublingual gland removal | Covered (if criteria met) | CPT 42440, HCPCS D7981 | Sublingual gland removal is adjunct, not standalone covered indication |
| Tympanic neurectomy | Covered (if criteria met) | CPT 69676 | Neural intervention; ENT specialty most likely billing this |
| Transoral submandibular ganglion neurectomy | Not Covered | CPT 36470, CPT 49185 | Aetna excludes this approach |
| Kinesio taping | Not Covered | — | Not considered medically necessary by Aetna |
| Sialodochoplasty (primary or secondary) | Related — Not Standalone Covered | CPT 42500, CPT 42505 | Listed as related codes, not covered for this indication |
| Sialography (injection + imaging) | Related — Not Standalone Covered | CPT 42550, CPT 70390, HCPCS D0310 | Diagnostic context only; not covered under sialorrhea surgical criteria |
Aetna Sialorrhea Billing Guidelines and Action Items 2025
These are not suggestions. Do these things before the effective date of September 26, 2025 — or before your next claim submission if that date has passed.
| # | Action Item |
|---|---|
| 1 | Audit your documentation templates for sialorrhea cases. Your clinical notes must explicitly reference one of the three morbidity conditions Aetna names: skin maceration, poor oral hygiene, or dehydration. Generic documentation about "excessive drooling" won't satisfy Gate 1 of the medical necessity test. |
| 2 | Build a conservative treatment failure checklist into your pre-surgical workflow. Before any patient goes to surgery, your chart needs to show attempted and failed physical therapy and drug therapy — both. Create a structured note section or intake form that captures treatment type, duration, and outcome for each modality. |
| 3 | Remove CPT 36470 and CPT 49185 from your sialorrhea charge capture for Aetna patients. These codes are mapped to non-covered indications under CPB 0265. Billing them for this diagnosis will generate denials. If your billing team uses a sialorrhea procedure grouper or charge set, purge those codes from it now. |
| 4 | Flag ICD-10 codes K11.1 and K11.7 in your EHR for sialorrhea billing review. These are the two diagnosis codes tied to this policy — K11.1 for hypertrophy of salivary gland and K11.7 for disturbances of salivary secretion. Any claim pairing these codes with the covered CPT codes needs the two-gate documentation review before submission. |
| 5 | Confirm prior authorization requirements with Aetna for each plan type. The CPB doesn't spell out a universal prior auth requirement, but these are surgical procedures with step-therapy prerequisites. The risk of submitting without prior authorization on a complex surgical case is not worth it. Call Aetna provider services or check the Aetna provider portal for plan-specific requirements tied to CPT 42507, 42509, 42510, or 69676. |
| 6 | Cross-train your oral surgery and ENT billing staff on the distinction between covered and related codes. CPT 42450 (sublingual gland excision) and CPT 42500/42505 (sialodochoplasty) appear in the policy as "related codes" — not covered codes. Billing staff who see those codes on operative reports may inadvertently include them as primary procedure codes. They shouldn't be. |
| 7 | If you're not certain how CPB 0265 applies to your payer mix or contract, talk to your compliance officer before the effective date. The two-gate criteria give Aetna significant discretion during medical review. If your practice has high volume of sialorrhea cases — particularly pediatric neurology patients with drooling secondary to cerebral palsy — get a compliance review of your documentation practices now. |
