Yes, certain insurance carriers consistently report higher claim denial rates, particularly within the Affordable Care Act (ACA) marketplace and for certain Medicare Advantage plans. Data from 2023–2025 frequently highlights carriers such as Molina Healthcare, UnitedHealthcare, Oscar Health, and Ambetter as having denial rates that can reach 30% or higher for in-network claims. Other major payers, including Aetna, Anthem, and Humana, are also frequently cited by providers for having stricter utilization management and higher rejection volumes.
However, a “high” denial rate is often tied to the specific plan type or the medical necessity criteria of a policy rather than just the carrier’s name. At The Medicators, we find that providers often struggle because they are not adjusting their documentation to meet the unique, strict clinical requirements of these specific high-denial payers.
Common Payers Frequently Cited for Higher Denial Volumes
While rates fluctuate by state and network, the following insurers are often flagged by medical practices for having more rigorous or automated claim review processes:
Marketplace/ACA Carriers: Molina Healthcare, Oscar Health, and Ambetter frequently see higher denial percentages due to tighter coverage mandates.
National Commercial Payers: UnitedHealthcare, Aetna, and Cigna often trigger denials based on detailed utilization management and prior authorization protocols.
Managed Care Organizations (MCOs): Anthem Blue Cross and Humana often apply strict automated screening tools that reject claims if documentation is missing even minor details.
The Reality of Denial Rates: Why Accurate Documentation is Required
You cannot effectively manage denials by blaming the insurance company alone. To prevent rejections, your practice must align its submission process with the specific payer’s rules. To ensure your claims are paid, our billing team emphasizes:
Payer-Specific Rules: Understanding that a claim accepted by one carrier may be rejected by another due to different documentation thresholds.
Automated Screening Compliance: Ensuring that your billing software and internal procedures are pre-scrubbing claims for the specific, rigid data fields these carriers require.
Clinical Justification: Providing robust, evidence-based documentation that clearly justifies medical necessity, which is the primary target for automated denials.
