House Healthcare Committee hears high-level briefing on Vermont commercial insurance markets

Noel Langwell, of the Joint Fiscal Office, briefed the Vermont House Committee on Healthcare on Jan. 17 on the structure and basic mechanics of the state’s commercial health insurance markets, including the individual, small‑group and large‑group markets and the increasing share of self‑insured coverage.

Langwell said the presentation was intended as a “high level health insurance 101,” and repeatedly cautioned he would not go into technical detail. He described the three commercial segments the state regulates — individual, small group and large group — and distinguished those from self‑insured employer plans and federal programs such as Medicare and Medicaid, which the state does not regulate. “Actuarial value is the average share of medical spending paid by a plan for a defined set of covered services across a population,” Langwell told the committee, explaining the federal bronze/silver/gold/platinum framework used to describe relative cost sharing.

The briefing summarized how the state’s exchange (Vermont Health Connect) works, how qualified health plans (QHPs) operate on the exchange and how state subsidies interact with federal premium tax credits. Langwell said Vermont supplements federal subsidies for people up to 300% of the federal poverty level under a federal waiver, and told the committee the most recent state subsidy cost he had reviewed was “about $7,000,000 gross,” with federal matching funds applying to some of that amount.

Langwell also reviewed market composition and trends, citing that roughly 74% of the commercial market is covered by self‑insured arrangements and that, in older published data, the large‑group insured population had declined (from about 116,000 in 2013 to about 17,000 in 2020 in the charts Langwell referenced). He noted a roughly 34,000‑person enrollment in individual plans in recent exchange data, and that about 82% of those exchange enrollees received some form of state or federal subsidy, leaving about 6,000 people paying the full premium cost in that slice of the market.

The presentation included definitions and examples of cost‑sharing features (deductibles, copayments, coinsurance), and how actuarial value translates into average plan liability (for example, silver plans are roughly 70% actuarial value while gold plans are about 80%). Langwell highlighted that plan design, market competition, projected medical and drug costs, regulatory assessments and administrative costs all feed into premium-setting.

Langwell described employer‑side tools that affect out‑of‑pocket exposure, such as health savings accounts (HSAs) and health reimbursement arrangements (HRAs). He explained one practical difference: HRAs are employer‑funded, often notional accounts that do not vest to employees, while HSAs are actual accounts that employees can own and in many cases roll over. Langwell noted that available data (the 2021 Vermont household health insurance survey) showed HSAs and HRAs present for a significant share of working‑age covered Vermonters (34% had HSAs, 13% HRAs, 9% had both, per that survey), and that those accounts can complicate measures of out‑of‑pocket burden because employer payments into HRAs may appear in claims or out‑of‑pocket tallies differently than direct consumer spending.

On risk pooling, Langwell reviewed community rating and guaranteed issue principles used in Vermont and the federal exchange, and summarized reinsurance/market‑level mechanisms such as risk adjustment that move funds between insurers who enroll lower‑cost and higher‑cost populations. He also noted Vermont’s experiment with a merged individual/small‑group market (implemented in 2017) has been temporarily unmerged and is scheduled to remerge on Jan. 1, 2026, unless the Legislature acts otherwise; he said that change would affect about 71,000 lives and could be the subject of future committee consideration.

Langwell outlined regulation and oversight: rate review and affordability oversight are handled by the Green Mountain Care Board, while solvency and insurer financial oversight are the Department of Financial Regulation’s responsibility. He reviewed the public rate‑filing process, including public comment and hearings, and reminded members that the Office of the Health Care Advocate has party status in rate reviews.

Committee members asked clarifying questions throughout the briefing about QHPs, the boundaries between large‑group insured and self‑insured plans, silver‑loading and premium‑setting mechanics, the flow and use of the claims assessment (the assessment on insurer claims that funds the state’s HIT fund and general fund), and medical loss ratio requirements. Langwell repeatedly deferred deep technical or policy answers to the subject matter experts present and indicated he would provide updated or more recent numbers as they become available.

The session concluded with committee members noting the breadth of the topic and signaling interest in follow‑up conversations that would examine narrower policy choices (for example, whether to merge markets or address silver‑loading), with expert witnesses and the Green Mountain Care Board or DFR participation expected in future briefings.
