Medicare benefits are protected property interests, and the claimants faced a permanent loss of benefits after reconsideration. Although due process is flexible under Mathews v. Eldridge, its core remains notice of the case against the claimant and a meaningful opportunity to answer it.
The court rejected the district court's assumption that under-$100 claims necessarily involved insubstantial private interests. Small medical claims may be serious losses for elderly beneficiaries, many of whom have limited incomes, significant medical needs, and disabilities that make navigating a paper-only system especially difficult. A beneficiary could also accumulate substantial yearly losses while remaining below the hearing threshold for each claim.
The Explanation of Medicare Benefits forms did not adequately identify why claims were denied. They often failed to distinguish among materially different grounds, such as an excessive charge, a charge above prevailing local rates, or treatment deemed unnecessary. Without knowing the actual basis for the denial or having access to the evidence relied on, a claimant could not intelligently prepare written rebuttal materials.
The lack of adequate notice was not offset elsewhere in the system. Claimants had no right to inspect the carrier's file, obtain a meaningful summary of the adverse evidence, or speak with someone knowledgeable about and empowered to resolve the dispute. A telephone number on a form was not a meaningful substitute for access to the reasons and evidence underlying the decision.
An oral exchange can improve accuracy even when a dispute does not turn solely on formal witness credibility. It can expose misunderstandings, clarify ambiguous records, focus the actual dispute, and permit elderly claimants to explain their circumstances in a more accessible manner than written submissions allow. Oral contact is particularly important where good faith, fault, knowledge, or credibility bears on entitlement or waiver of liability.
The court also identified structural reasons for concern about erroneous denials. Reconsideration was conducted by another employee of the same private carrier that made the initial decision, and the carrier had financial incentives to limit payments. With no subsequent appeal, no direct contact with the decisionmaker, and inadequate notice, the procedures created an unacceptable risk of error.
