TL;DR: Aetna, a CVS Health company, modified CPB 0625 governing dysphagia therapy coverage, effective October 8, 2025. Billing teams using CPT 92507, 92526, 43497, and related esophageal procedure codes need to verify patient criteria now — several high-exposure interventions remain explicitly excluded.

Aetna Dysphagia Therapy Coverage Criteria and Medical Necessity Requirements 2025
The Aetna dysphagia therapy coverage policy under CPB 0625 Aetna system covers four specific interventions — and only those four. Everything else is experimental. That narrow scope is the first thing your billing team needs to understand.
For speech therapy, Aetna requires the member to meet at least one of three criteria. First, the member has documented weight loss or malnutrition caused by dysphagia. Second, the member has a history of recurrent aspiration or choking, or is at high risk for it. Third, the member is unable to swallow and depends on a nasogastric or gastrostomy tube for nutrition.
Notice what is not required: a communication disability. Aetna explicitly covers speech therapy for dysphagia regardless of whether a communication impairment exists. Bill CPT 92526 (treatment of swallowing dysfunction) or CPT 92507 (individual speech treatment) when any of the three criteria above are documented in the chart. CPT 92508 covers group sessions. For home health and hospice settings, bill HCPCS G0153. Home-based per diem services use S9128.
The other three covered interventions each carry their own medical necessity criteria. Esophageal dilation (CPT 43220, 43226, 43450, 43453, and related codes) requires symptomatic obstruction. Non-biodegradable, non-drug-eluting stent placement — billed with HCPCS C1874 or C1875 — covers refractory malignant esophageal strictures that cannot reach adequate diameter through dilation. Per-oral endoscopic myotomy (POEM), billed as CPT 43497, is covered for type III (spastic) achalasia only. ICD-10 K22.2 supports esophageal obstruction claims. ICD-10 K22.0 supports POEM claims — but your documentation must specify type III.
The policy does not mention a blanket prior authorization requirement in its criteria language. That said, Aetna's broader authorization rules often apply to surgical procedures like POEM and endoscopic stent placement. Check your specific plan contracts before assuming prior auth is not required on CPT 43497 or CPT 43266. If you're unsure, loop in your compliance officer before the October 8, 2025 effective date.
Reimbursement exposure here is real. POEM procedures carry significant fee schedule weight. A denied CPT 43497 claim for the wrong achalasia type is an expensive write-off.
Aetna Dysphagia Therapy Exclusions and Non-Covered Indications
Seventeen specific interventions are experimental, investigational, or unproven under this coverage policy. That's a long list, and several of them generate frequent billing questions.
Electrical stimulation is fully excluded. That means CPT 97014 (unattended electrical stimulation), CPT 97032 (manual electrical stimulation), and HCPCS E0745 (neuromuscular stimulator) are not covered for dysphagia. This includes neuromuscular electrostimulation and pharyngeal electrical stimulation. HCPCS E0720 and E0730 (TENS devices) are also not covered here.
Acupuncture — CPT 97810 through 97814 — is excluded. Full stop.
Transcranial magnetic stimulation for dysphagia is not covered. CPT 90867, 90868, and 90869 all fall into the excluded bucket for this indication.
Hyperbaric oxygen therapy for radiation-induced dysphagia is excluded. That means CPT 99183, HCPCS G0277, HCPCS A4575, and HCPCS E0446 will not pass medical necessity review under this policy.
The Swallow STRONG program and similar intensive dysphagia rehabilitation approaches are explicitly called out as unproven. This is notable because these programs are being actively marketed to practices and hospital systems. Bill one of those claims, and you'll get a denial.
POEM for any achalasia type other than type III is also excluded. This is a critical split. If your documentation says type I or type II achalasia, CPT 43497 is not covered. Only K22.0 with clear type III designation in the clinical notes will support the claim.
The real issue with this exclusion list is that several of these modalities — electrical stimulation in particular — are used routinely in rehabilitation settings. Therapists treating dysphagia as part of stroke recovery (ICD-10 I69.091 through I69.991) may combine covered speech therapy with electrical stimulation in the same session. The electrical stimulation component is not covered. Bill accordingly, and make sure your documentation separates the services clearly to avoid a global claim denial.

Aetna Dysphagia Billing Guidelines and Action Items 2025
These steps apply starting October 8, 2025. Work through them before that date.
| # | Action Item |
|---|---|
| 1 | Audit your active dysphagia speech therapy patients against the three criteria. Pull all open cases billed under CPT 92507, 92508, or 92526. Each case needs chart documentation supporting at least one of the three medical necessity criteria — weight loss/malnutrition, aspiration risk, or tube-feed dependence. If documentation is thin, contact the treating clinician now to get a clinical note updated before the next billing cycle. |
| 2 | Separate electrical stimulation from covered speech therapy services in your charge capture. If your therapists combine swallowing therapy with electrical stimulation (CPT 97014 or 97032, or HCPCS E0745), stop billing those units together under a dysphagia diagnosis. The speech therapy component is covered. The electrical stimulation is not. Bundled claims will trigger a denial and potentially flag a pattern for audit. |
| 3 | Confirm POEM documentation specifies type III achalasia before billing CPT 43497. This is the highest-dollar risk on this policy. A surgical claim for POEM using ICD-10 K22.0 without type III specificity in the operative report will be denied. Make sure your surgeons' documentation — not just the code — explicitly states spastic or type III achalasia. Train your coders to query the physician if that language is absent. |
| 4 | Verify stent type before billing HCPCS C1874 or C1875. Aetna covers non-biodegradable, non-drug-eluting stents for refractory malignant strictures. Biodegradable stents and drug-eluting stents are excluded. If your supply chain uses biodegradable stents, that cost is not recoverable under this policy. Flag this with your materials management team. |
| 5 | Check plan-level speech therapy benefit limits. The policy notes that some plans limit speech therapy services even when medical necessity criteria are met. A patient who qualifies clinically may still hit a plan-level cap. Pull benefit information at the time of authorization — not after the claim denies. |
| 6 | Stop billing AI-based dysphagia management tools to Aetna. If your practice or hospital system has adopted an AI swallowing assessment or management platform, Aetna has explicitly designated it experimental. There is no covered path for AI-based dysphagia technology under this policy right now. Document that in your clinical billing guidelines and route those encounters to self-pay or appropriate secondary coverage if available. |
| 7 | Cross-reference CPB 0621 for drug-eluting stent questions. Drug-eluting stents for esophageal strictures — malignant or benign — are excluded here and governed by a separate policy. If you're billing stents for dysphagia-adjacent indications, pull CPB 0621 before submitting. |
If your practice has high volume in any of these categories — stroke rehab dysphagia, achalasia surgery, or esophageal oncology — talk to your compliance officer about a focused chart audit before October 8, 2025.
