Claim Appeal Deadline Requirements

What Are Claim Appeal Deadlines

Claim Appeal Deadlines establish the maximum time permitted to request review of a denied claim after receiving a denial notice. Medicare requires redetermination requests within 120 days of the denial notice. Commercial carriers vary: UHC allows 60 days; Anthem allows 365 days; Aetna allows 180 days; Cigna allows 180 days. Data from the Healthcare Financial Management Association shows 70-80% of appealed denials are successfully overturned on first appeal, indicating substantial potential for recovery of unpaid claims.

Who It Affects

Healthcare providers, billing departments, compliance staff, and appeal specialists must track and manage appeal deadlines. Insurance carriers adjudicate appeals submitted within deadlines. Patients benefit when providers pursue appealed denials, as successful appeals result in payment. Medical practices with large claim volumes benefit significantly from systematic appeal processes. Compliance teams must ensure no appealed claims miss deadlines.

Key Requirements

1. Submit Medicare redetermination requests within 120 days of denial notice date
2. Submit UHC appeals within 60 days of denial notice
3. Submit Anthem appeals within 365 days of denial notice
4. Submit Aetna appeals within 180 days of denial notice
5. Submit Cigna appeals within 180 days of denial notice
6. Include all clinical documentation supporting the appealed service
7. Reference the original claim and denial reason in the appeal
8. Maintain documentation that the appeal was submitted within the deadline

Timeline and Enforcement

Appeal deadlines are strictly enforced by all carriers. Missing an appeal deadline forfeits all rights to appeal, even if the original denial was erroneous. Carriers typically respond to appeals within 30-60 days. If an appeal is denied at the first level, additional appeal levels exist (reconsideration, appeals council, litigation), each with its own separate deadline. CMS monitors appeal processing times as part of plan oversight activities.

How to Comply

1. Establish a denial tracking system organized by carrier and appeal deadline
2. Set automatic calendar reminders for appeal deadlines before they expire
3. Assign staff responsibility for reviewing all denials for appealability
4. Prioritize appeals with high probability of success based on denial reason
5. Gather supporting clinical documentation before submitting the appeal
6. Submit appeals electronically with proof of receipt when possible
7. Track appeal responses and escalate to higher levels if denied at first level
8. Measure appeal overturn rates to identify patterns in denial reasons
