The Medical Frailty Crisis: How Rushed Implementation Threatens Medicaid's Most Vulnerable

Since the passage of budget reconciliation act of 2025 (H.R. 1), states have been creating draft work requirement systems without clear federal parameters, operating under an 18-month timeline widely viewed as woefully inadequate. This issue is no longer hypothetical. As STAT News reports today, Nebraska is days away from beginning to disenroll Medicaid beneficiaries who cannot demonstrate compliance with the new work requirements, offering an early glimpse of the challenges other states will face. With only five months remaining before the January 2027 deadline, an interim final rule substantially changes how states must identify beneficiaries who qualify for the law’s medical frailty exemption, requiring states to revisit some of the most administratively complex parts of implementation.

State Medicaid agencies now face the difficult task of building individualized medical frailty assessment systems while simultaneously preparing to launch work requirements on a fixed federal timeline. The challenge is not merely administrative—evidence from previous Medicaid work requirement demonstrations suggests that implementation choices can determine whether eligible individuals maintain coverage.

As referenced in AcademyHealth’s recent Decisionmaker’s Guide to Competing Health Evidence edition, Arkansas’ 2018 implementation of work requirements is our closest real-world parallel, and the results were stark. Thousands lost coverage, employment did not rise, and studies found that most who lost coverage were actually qualified yet failed to navigate the reporting requirements to prove it. The interim rule’s medical frailty provisions create even more complex hurdles, which begs a critical question: how will people with serious medical conditions navigate an even more demanding system while simultaneously managing their illnesses?

Earlier this year, Medicaid Medical Directors writing in JAMA Health Forum argued that successful implementation would require operational flexibility, diverse data sources, and streamlined administrative processes. The interim final rule instead emphasizes individualized determinations over the operational flexibility many state Medicaid leaders had recommended.

When Vague Definitions Meet Implementation Reality

Although “medical frailty” has existed in Medicaid policy before, it has historically been used in the context of expanding access to care. Under H.R. 1, the same concept now determines who can avoid losing coverage, raising the stakes of how states define and operationalize the exemption.

H.R.1’s work requirements included medical frailty exemptions with five categories. Four of these categories were straightforward and aligned with existing disability frameworks that states already used for identification purposes. Recipients of Supplemental Security Income (SSI) or Social Security Disability Insurance (SSDI) would be exempt, as would those with “disabling” mental disorders or physical, intellectual, or developmental disabilities that significantly impair activities of daily living.

The fifth category, individuals with a “serious or complex medical condition,” introduced significant ambiguity, creating one of the most pressing implementation challenges states now face. When CMS’ preliminary guidance in December failed to provide clarity, states seeking to meet the January 2027 deadline had to move forward with implementation plans regardless. An early 2026 survey revealed most states planned to use Medicaid claims data to verify medical frailty, with some identifying specific diagnostic and service codes and 30 states hoping to allow people to self-attest to frailty when verification data are not available.

Rather than allowing states to identify medically frail individuals based on qualifying diagnoses or existing clinical criteria, the June interim final rule requires states to determine whether each individual’s specific condition prevents them from meeting the work requirement. States may still develop lists of relevant health conditions, but those conditions cannot automatically qualify someone for an exemption.

Upending State Plans

The mandate for individual assessments creates a significant administrative burden for states, forcing states to rethink systems for individualized review. This guidance, provided six months in advance of the deadline, not only adds to the already substantial costs associated with building these systems but also exacerbates challenges for health departments already operating under strained capacities. Further, the interim final rule significantly restricts states’ ability to accept self-attestation of frailty. While this will be temporarily permitted through 2027, individuals are still required to provide full documentation at their six-month renewal.

Nebraska, who launched its program in May eight months ahead of the deadline, relied on their near 300-page index of diagnosis and procedure codes and self-attestation process to identify individuals who would qualify as medically frail. Under the new CMS guidance, they now must re-work their system since they cannot categorically exempt individuals.

The Human Impact

Evidence from prior Medicaid work requirement demonstrations suggests that administrative design can have substantial consequences. As seen in Arkansas, people fall through the cracks when navigating bureaucracy to prove they qualify for the exemption. Even without work requirements, the Medicaid system writ large is riddled with obstacles for beneficiaries. A survey of Medicaid recipients revealed one in three respondents encountered difficulties at enrollment and one in four at renewal, citing barriers like long wait times, complex paperwork, and inadequate communication systems. Notably, Medicaid enrollees not only report difficulties with their insurance but are also more likely to experience declines in health or unmet treatment needs due to these issues compared to those with other forms of coverage.

The interim rule introduces even more complex administrative steps that demand the most from those with the least to give, especially since the population at risk for enrollment has a high prevalence of chronic and potentially function-limiting conditions. Sick individuals must gather energy their illnesses have stolen and navigate systems with resources they don’t have to prove they are worthy of health care. The interim rule’s case-by-case assessments could force work requirements on:

• A cancer patient between treatments, still struggling with debilitating fatigue

• People with autoimmune diseases like lupus or rheumatoid arthritis whose symptoms flare unpredictably

• Unhoused individuals with serious conditions but no consistent medical provider

• Rural residents with chronic pain who can’t reach specialists for proper diagnosis

A Call to Action

When these individuals lose coverage, they lose access to the very treatments keeping their conditions manageable, leading to a cascade of preventable suffering.

The window for course correction is closing. With the interim final rule’s comment period ending tomorrow July 31, CMS needs to hear from researchers, providers, and advocates about why these medical frailty provisions will fail to protect our must vulnerable patients and why states need more time to build functioning systems.
