Aetna denied out-of-network coverage? Here’s what to do

Why Aetna denied out-of-network coverage

• No in-network provider offered the needed service within a reasonable distance or time.
• Continuity-of-care rules were not applied after a provider left the network.
• The claim was processed at out-of-network rates by default.

Calling Aetna: what to expect

Aetna’s line is 1-800-872-3862; member services is typically Mon–Fri, roughly 8am–6pm in your time zone; some plans staff weekends.

To reach a person: enter or say your Aetna member ID, then say "claims" for a denial, or "authorization" for a prior-auth question, then say "representative" to reach a person. Menus change — if yours does not match, say "representative" at any prompt.

Self-service runs through Aetna Health app / aetna.com (https://www.aetna.com); the written route is the Aetna Member Complaint and Appeal Form (available on aetna.com; a letter with the same details is also accepted); and you may see these names on your paperwork: Aetna Health app, CVS Caremark (pharmacy).

Step by step: what to do

1. Call Aetna at 1-800-872-3862 (enter or say your Aetna member ID, then say "claims" for a denial, or "authorization" for a prior-auth question, then say "representative" to reach a person) and ask whether an in-network provider was actually available.
2. Request a network-adequacy or gap exception so the care is covered in-network.
3. Provide documentation that no suitable in-network option existed.
4. File a written appeal through the appeal address on your denial letter or the Aetna member portal before the 180 days from the date of the denial deadline.

Common mistakes to avoid

• Assuming out-of-network always means no coverage — exceptions exist.
• Not documenting the lack of an in-network option.

What to say when you call Aetna

• There was no in-network provider available, so I’m requesting a network-adequacy exception.
• Please reprocess this at the in-network benefit level.

Aetna-specific things to know

• Aetna calls it a "network deficiency" or "gap" exception; the request usually needs the provider’s NPI and the reason no in-network option worked.
• Aetna’s Open Choice PPO plans pay out-of-network at a lower rate; HMO plans generally pay nothing without an exception.
• Aetna is part of CVS Health, so pharmacy denials come from CVS Caremark and have their own appeal process and phone line.
• Aetna Medicare Advantage members use a different member services number and a Medicare appeals timeline (60 days, not 180).
• The Aetna Health app shows claim status and lets you message member services; written messages are a paper trail.
• Aetna’s clinical policy bulletins (CPBs) are public — a denial usually cites one, and reading it tells you exactly what documentation would overturn it.

Know your rights

You have the right to a written explanation of any denial, to a full copy of your plan documents, and to appeal — first internally, then through an independent external review.

Regulator: your state Department of Insurance (and the federal No Surprises Act). If the internal appeal fails, request an external review and file a complaint with your state Department of Insurance.

If Aetna will not move, the escalation paths that carry weight:

• Ask for a second-level appeal if your plan offers one, or an expedited appeal when a delay would harm your health.
• Request independent external review — Aetna uses an independent review organization once internal appeals are done.
• File with your state Department of Insurance, or the Department of Labor for employer plans.
