State Medicaid Data Visibility Index

This page organizes dated records about limits in Medicaid and waiver data visibility. Each entry states what the source reported, why it matters for review, and what the record cannot prove.

What the categories mean

Federal data submission

Records about the completeness, consistency, or timing of data states provide for federal Medicaid oversight.

Eligibility visibility

Records about whether available data allow reviewers to understand application, renewal, or disenrollment outcomes.

Waiting-list visibility

Records about how waiver capacity and waiting-list practices are documented and compared.

Public-record access

Dated request records showing the preserved status and completeness of a specific public-record trail.

Reporting framework

Federal requirements intended to make future state reporting more consistent and publicly available.

Official oversight record

Federal and multi-state records

These entries summarize reports from GAO, HHS OIG, CMS, and MACPAC. The dates matter. A historic gap may have changed after the source was published.

Multiple states Assessment limited by source data

Application-processing pace could not be assessed

What the source says

GAO reported that it could not assess whether states processed applications at a rate that kept pace with new applications because most states provided incomplete or inconsistent data.

Visibility context

Incomplete or inconsistent state reporting limited a federal review of application-processing performance.

Limit

The report covers state experiences from 2008 through 2011. It does not establish why any state data were incomplete or inconsistent.

Open official source: U.S. Government Accountability Office, GAO-13-55
Multiple states Participation described as limited

Medicaid interstate-match participation was limited

What the source says

HHS OIG reported limited state participation in the Medicaid Interstate Match. OIG also reported that CMS guidance was limited and that states said they needed more guidance.

Visibility context

Variation in enrollment-data submission and follow-through limited the federal matching process used to identify possible duplicate enrollment.

Limit

This is a 2014 evaluation of an August 2011 match sample. The record does not describe current participation.

Open official source: HHS Office of Inspector General, OEI-09-11-00780
Multiple states Historic implementation gap

T-MSIS did not yet include all state Medicaid programs

What the source says

HHS OIG reported that 21 of 53 state programs were submitting data as of December 2016. States and CMS also raised concerns about incomplete elements, reliability, and differing interpretations.

Visibility context

The delays and inconsistent definitions limited reliable national analysis at that time.

Limit

This is a dated implementation snapshot. It must not be read as the current T-MSIS status.

Open official source: HHS Office of Inspector General, OEI-05-15-00050
All states and the District of Columbia Practices vary by waiver

Waiver waiting-list practices were documented in different ways

What the source says

MACPAC reviewed 268 approved waivers. It reported that 199 of 254 Section 1915(c) waivers and 11 of 14 Section 1115 waivers documented how waiting lists were managed.

Visibility context

Different waiver-entry rules and state practices make waiting-list numbers an imperfect measure of unmet need.

Limit

The compendium reflects approved waivers as of March 2020. MACPAC cautions that a documented waiting-list policy does not prove that a waiver had an operational waiting list.

Open official source: Medicaid and CHIP Payment and Access Commission
All states and the District of Columbia Improved; some standards unmet

T-MSIS data improved, but important gaps remained

What the source says

GAO reported broad improvement in T-MSIS data. It also reported that 30 states did not submit acceptable inpatient managed-care encounter data and that eight related recommendations remained not fully addressed.

Visibility context

Data that did not meet CMS standards limited oversight of services and payments in the affected topic areas.

Limit

The report evaluates CMS assessments available during GAO’s review. It does not say that all data from any listed state were unusable.

Open official source: U.S. Government Accountability Office, GAO-21-196
All state Medicaid programs with applicable HCBS Future reporting framework

Federal rule adds waiting-list and website-transparency reporting

What the source says

CMS states that the 2024 Access Final Rule requires states to report on waiver waiting lists and service-delivery timeliness and to publish specified HCBS quality, performance, and compliance information.

Visibility context

The rule establishes a more consistent reporting framework for information that was not previously subject to the same nationwide public-reporting requirements.

Limit

Implementation dates vary. This entry describes a reporting requirement, not proof that a state is currently compliant or noncompliant.

Open official source: Centers for Medicare & Medicaid Services, HCBS provisions
All states and the District of Columbia Updated data lagged preliminary data

Updated eligibility-redetermination data arrived months later

What the source says

GAO reported that CMS publicly shared preliminary and updated state data for Medicaid and CHIP unwinding. The updated data generally lagged the preliminary data by five or more months and included outcomes for millions of cases that had been pending.

Visibility context

A preliminary snapshot could differ materially from the later, more complete record.

Limit

The report concerns the COVID-19 continuous-enrollment unwinding period. A reporting lag does not establish intentional withholding.

Open official source: U.S. Government Accountability Office, GAO-25-107413

State-level preserved records

Connecticut public-request records

These are narrow archive snapshots. They show the preserved request fields and evidence gaps. They do not decide whether an agency met a legal deadline or produced every responsive record.

Connecticut Archive status: Awaiting Response

DSS request for Medicaid billing, ADA, and related records

The preserved request export records a submission to the Connecticut Department of Social Services on November 13, 2024. Its archive status is Awaiting Response. No exact request-ID-linked response thread was safely attributable in the accessible source set.

Visibility context
The archive preserves the request and its status while clearly identifying the missing response-thread evidence.
Limit
The archive status is not a legal finding and does not establish that the agency failed to respond. The supplied external MuckRock URL returned Page Not Found during a July 19, 2026 archive check.
Open preserved request record
Connecticut Archive status: Processing

OPM request concerning ADA compliance and interagency correspondence

The preserved request export records a submission to the Connecticut Office of Policy and Management on November 22, 2024, with tracking number OPM ID # 24-94. Its archive status is Processing. The export also contains a January 9, 2025 completion timestamp, but no exact linked response thread was safely attributable.

Visibility context
The preserved fields conflict in a way that requires the source record to remain visible without guessing which field controls.
Limit
The record is disclosed as internally inconsistent. It is not classified as a denial, delay finding, or proof of misconduct.
Open preserved request record
Connecticut Recovered partial trail

Recovered OPM acknowledgment correspondence

The archive preserves one February 26, 2025 acknowledgment from Connecticut OPM Legal Affairs. The message referred to an attached letter, but the attachment and complete request-response thread were not recovered in the accessible source set.

Visibility context
The entry shows exactly what was recovered and what remains unavailable for independent review.
Limit
A partial trail cannot establish the full agency response, timing, or outcome.

Method and limits

  1. Use a dated official report or an exact preserved public-request record.
  2. State what the source reports without adding a motive or legal conclusion.
  3. Explain the visibility issue in plain language.
  4. Publish the limitation beside the summary.
  5. Keep historic records dated. Do not present them as current status.

This is a bounded index, not a complete census of every state or every Medicaid dataset. Corrections can be submitted through the archive’s corrections policy.
