Aetna: timely filing limit
Initial claim
90 days from date of service for participating/in-network commercial providers; non-participating providers commonly have up to 12 months, per Aetna's published guidance
Clock starts from: date of service
Appeal window
No published default appeal window. Check the payer's own appeals policy.
Caveats
The published default varies further by product (commercial, Medicare Advantage, Aetna Better Health Medicaid plans) and by the specific network contract. This entry reflects secondary-source reporting on Aetna's provider guidance rather than a directly confirmed page from aetna.com; verify against the current provider manual for the member's specific plan before acting.
