How To Submit Claims To Aetna Health

For Aetna Health, the practical claims workflow usually starts with electronic submission guidance and only falls back to paper instructions when the payer documents a mailing address for specific claim types or exceptions. The details below keep the workflow broad instead of reducing it to a single address.

At a glance

• Aetna supports electronic claim submission through its provider portal ecosystem, including Availity. Official materials also reference paper claim mail-to addresses that vary by product and state; one annual notice lists a Lexington, KY paper-claims address for HMO & PPO products. Claims status can be checked electronically or by phone, depending on product.

Caveats

• Paper claim addresses vary by product, state, and notice; do not assume the Lexington address is universal.
• This research did not confirm a single electronic payer ID from official Aetna sources.
• Some Aetna products route claims and inquiries through different phone numbers and administrative paths.
