Policy Overview and Implementation
Aetna has announced a groundbreaking transformation in its inpatient reimbursement policy for Medicare Advantage and Special Needs Plans (SNPs), set to take effect on November 15, 2024. This comprehensive policy overhaul represents a significant shift in how healthcare providers will receive compensation for inpatient services under Aetna’s Medicare programs.
The insurance giant’s primary objective centers on accelerating the reimbursement process for healthcare providers while maintaining quality care standards. According to Aetna’s official communication to providers in August, the company stated: “Our goal is simple: We want to help you get reimbursed faster for inpatient admissions that are initially denied. You’ll receive faster payment and still be allowed to appeal for a higher payment.”
This Medicare Advantage reimbursement reform addresses long-standing concerns within the healthcare industry regarding delayed payments and complex approval processes that have historically burdened both providers and patients.
Detailed Coverage and Eligibility
Eligible Hospital Admissions
The new policy specifically targets urgent or emergent hospital admissions for Medicare Advantage and Special Needs Plans members, but includes important parameters that providers must understand. The coverage applies exclusively to hospital stays that span at least one midnight, creating a clear distinction between eligible and ineligible admissions.
Hospital admissions lasting less than one midnight remain subject to standard CMS medical necessity reviews, maintaining the traditional approval process for these shorter stays. This selective approach ensures that the policy focuses on cases where payment delays have historically caused the most significant operational challenges for healthcare facilities.
The policy’s scope encompasses both Medicare Advantage plans and Special Needs Plans, affecting a substantial portion of Aetna’s membership base and creating widespread implications for healthcare providers across the network.
Payment Rate Structure
Under the new inpatient reimbursement framework, Aetna has established a dual-tier payment system that automatically determines compensation based on clinical severity assessments. This innovative approach eliminates the traditional binary approval-denial model in favor of a more nuanced payment structure.
When a case meets MCG (Milliman Care Guidelines) criteria for inpatient care, providers receive reimbursement at the full inpatient contracted rate. This ensures that genuinely complex cases requiring intensive hospital resources receive appropriate compensation levels.
Conversely, cases that don’t meet inpatient criteria receive payment at a lower observation-level rate, even when patients remain overnight. This approach acknowledges the care provided while reflecting the reduced resource intensity compared to full inpatient services.
Revolutionary Changes in Processing
Automatic Approval System
The most significant transformation in Aetna’s approach involves the implementation of an automatic approval system for eligible inpatient admissions. Under this new framework, Aetna eliminates upfront medical necessity reviews, dramatically reducing administrative burden and processing delays.
This streamlined approach represents a fundamental shift from reactive to proactive payment processing, where eligible admissions receive immediate approval status regardless of their ultimate reimbursement rate. Healthcare providers can expect faster cash flow and reduced administrative overhead as a direct result of this policy change.
The automatic approval mechanism particularly benefits emergency departments and urgent care facilities, where rapid decision-making is crucial for patient care and operational efficiency.
End of Traditional Denials
Perhaps the most revolutionary aspect of Aetna’s new policy involves the elimination of traditional denial notifications for admissions that don’t meet inpatient criteria. Instead of issuing denials, Aetna will process these stays as approved but reimburse them at the lower observation rate.
This fundamental change eliminates the adversarial relationship often created by denial letters and subsequent appeals processes. Healthcare providers no longer face the uncertainty of complete payment denial, knowing that approved admissions will receive some level of compensation.
The policy shift acknowledges that patients received legitimate care services, even if the intensity level didn’t warrant full inpatient reimbursement rates. This approach maintains the economic relationship between providers and insurers while reflecting actual care delivery patterns.
Appeals and Dispute Resolution
The new reimbursement structure necessitates significant changes in how providers challenge payment determinations. With traditional medical necessity appeals and peer-to-peer review processes no longer applicable, providers must navigate the payment dispute process outlined in their contracts.
This shift requires healthcare providers to understand their contractual dispute resolution mechanisms thoroughly, as these processes will become the primary avenue for challenging reimbursement rates. The change emphasizes the importance of comprehensive contract review and understanding dispute timelines and procedures.
Providers should prepare their billing and administrative teams for these procedural changes, ensuring staff understand when and how to initiate payment disputes under the new framework. Training programs and policy updates will be essential for smooth transition implementation.
CMS Two-Midnight Rule Integration
Aetna’s policy changes align with the CMS two-midnight rule finalized in January 2024, which requires Medicare Advantage plans to follow specific criteria for determining inpatient versus outpatient status. This federal regulation helps standardize admission billing practices across the industry.
Under the two-midnight rule, hospital stays qualify for inpatient reimbursement when the admitting physician expects the patient to require care spanning at least two midnights. Stays expected to last less than two midnights typically receive outpatient or observation classification with corresponding lower reimbursement rates.
Aetna’s new policy framework works within these CMS guidelines while providing greater payment certainty for providers. The alignment ensures compliance with federal regulations while addressing industry concerns about payment delays and administrative complexity.
Benefits for Healthcare Providers
The streamlined reimbursement process offers multiple advantages for healthcare providers, including improved cash flow predictability and reduced administrative costs. Providers can expect faster payment processing times and fewer resources dedicated to appeals and authorization processes.
Emergency departments, in particular, benefit from this policy change, as urgent and emergent admissions represent a significant portion of their patient volume. The automatic approval system reduces uncertainty around payment authorization for these critical care situations.
Rural and smaller hospitals may experience particularly positive impacts, as they often lack extensive administrative resources to manage complex appeals processes. The simplified payment structure can improve their financial stability and operational efficiency.
Industry Impact and Future Implications
Aetna’s policy innovation may influence other Medicare Advantage plans to adopt similar approaches, potentially reshaping industry-wide reimbursement practices. The focus on payment certainty and administrative efficiency addresses key provider concerns that have persisted across the healthcare industry.
This Medicare Advantage policy change reflects broader trends toward value-based care and administrative simplification in healthcare reimbursement. Success with this model could accelerate adoption of similar approaches across other insurance products and markets.
Healthcare providers should monitor the policy’s implementation closely, documenting outcomes and operational impacts to inform future contract negotiations and strategic planning. The policy represents a significant shift in insurer-provider relationships that could have lasting implications for healthcare economics.
