Aetna Claim Payment Timelines for Providers
What Aetna's payment timelines actually are, from the Medicare Advantage floor to timely filing, and how Copay pays you the next business day regardless.
Data as of June 2026. Every figure below is sourced.
What is required by law
These payment floors are set by federal regulation and are the most solid, citable figures for Aetna.
Medicare Advantage
Verified30 days
Federal floor: a Medicare Advantage plan must pay 95% of clean claims from non-contracted providers within 30 days of receipt, with interest if late; all other non-contracted claims within 60 calendar days. Contracted-provider timing is set by the agreement.
42 CFR §422.520: Prompt payment by Medicare Advantage organization
Timely filing limits
The deadline to submit a claim from the date of service. Limits can vary by your specific contract and state law.
Commercial, in-network
Commonly cited as 90 days from date of service (one source cites 120 days; not confirmed in Aetna's primary manual)
Out-of-network
12 months from date of service
Commercial payment timing
Industry pattern, not a payer commitment
Industry-sourcedAetna does not publish a specific commercial clean-claim payment timeline; commercial timing is governed by state prompt-pay law and your contract. Industry sources commonly cite roughly 14 to 30 days for clean claims (about 14 to 21 days electronic, 30 to 45 days paper), but this is an industry-typical pattern, not an Aetna-published commitment.

How Copay works with Aetna claims
Copay purchases your eligible Aetna claims and pays you the next business day, regardless of how long Aetna takes to adjudicate. You connect your billing software once and submit claims exactly as you do today. It is non-recourse, so a denied eligible claim is Copay's loss, not yours.
Aetna, answered
Aetna does not publish a specific commercial payment timeline; it is governed by state prompt-pay law and your contract. Industry sources commonly cite about 14 to 30 days for clean claims, but that is a general pattern, not an Aetna commitment. For Medicare Advantage, the federal floor requires 95% of clean claims from non-contracted providers to be paid within 30 days.
Industry sources commonly cite 90 days from the date of service for in-network commercial providers (one source cites 120 days) and 12 months for out-of-network. This is not confirmed in Aetna's primary provider manual, and your specific contract or state law can differ, so confirm against your agreement.
Yes. Copay purchases your eligible Aetna claims and funds you the next business day instead of waiting out Aetna's adjudication. It is non-recourse and does not change how your billing team works.
Common, generally-known categories include missing or expired prior authorization, medical necessity under Clinical Policy Bulletins, out-of-network or experimental services, coding and documentation errors, coordination of benefits, eligibility, and timely filing.
