Medical frailty is becoming more than an exemption category. CMS’s September 8 implementation guidance establishes a verification framework that can require states to connect eligibility systems with claims, encounter, clinical, and other reliable data while preserving a pathway for individualized review. The result is a new Medicaid control environment in which condition lists, code sets, data availability, decision logic, and historical evidence may all determine whether a community-engagement exclusion can be defended later.
What CMS is asking states to build
CMS’s September 8 guidance describes medical frailty as a verification process, not simply a list of exempt conditions. States must develop and maintain a justifiable list of qualifying conditions, provide a pathway for conditions not captured by that list, and first attempt to verify medical frailty ex parte using reliable information already available to the state.
That information can include paid, pended, and denied claims from the prior 12 months, managed-care encounter data, health information exchange data, and other reliable clinical or administrative information. The result is a determination process that may depend on multiple systems, data sources, code sets, and evidence pathways.
The control question
For every medical-frailty determination, a state should be able to reconstruct:
Condition-list governance → available reliable data → ex parte verification → clinical/evidence logic → exclusion determination → manual-review fallback → annual reverification → retained audit evidence
The issue is not simply whether an individual ultimately qualified for the exclusion. The state may also need to demonstrate what information was available when the decision was made, which rules and code sets were in effect, how that evidence was evaluated, and why the resulting determination was supported.
The 2028 transition matters
CMS also establishes an important temporal control. Before January 1, 2028, documentation or self-declaration under penalty of perjury may be used when reliable information is unavailable or incompatible with the state’s systems. Beginning January 1, 2028, self-declaration generally may be used only once during a continuous enrollment period, with subsequent verification requiring reliable information or documentation.
That makes effective-date and rule-version controls particularly important. A verification pathway permissible for one determination may not be sufficient for a later determination involving the same beneficiary.
Why this matters operationally
Medical frailty therefore reaches well beyond eligibility policy. It can involve eligibility systems, claims and encounters, clinical data, HIEs, pharmacy and DME information, vendors, managed-care organizations, manual-review workflows, and annual reverification.
For audit readiness, the objective is not merely to automate the exclusion. It is to make the determination reconstructable.
