Vermont's 2027 Rate Cut Comes With a Reference-Pricing Order

Reference-based pricing replaces a negotiated hospital rate with an administered one: the payer caps reimbursement at a fixed multiple of the Medicare fee schedule, the benchmark commercial insurers price at roughly 254% of Medicare on average nationally (RAND, May 2024).

Vermont's Green Mountain Care Board put a hospital-fiscal-year-2027 deadline on adopting exactly that mechanism, in a Supplemental Order issued August 18, 2026, the same day it cut Blue Cross Blue Shield of Vermont's filed individual increase to 2.2% from a requested 6.5%.

Key Takeaways

• Four approved rate changes, each cut 2.9 to 4.3 points below what was filed, reducing 2027 premiums for roughly 67,000 Vermonters by about $24 million relative to the filings.
• The board required BCBSVT to use its own FY27 Hospital Budget Guidance for hospital cost assumptions rather than the ones the carrier built from its contract negotiations.
• Montana's state employee plan now caps at 200% of Medicare, stepping to 180% by 2026, after 234% generated an estimated $47.8 million in savings from fiscal 2017 through 2019.
• BCBSVT's risk-based capital ratio closed 2024 at 214% against a company target range of 500% to 700%, and AM Best's July 2026 positive outlook credited "more-favorable regulatory rate outcomes."

The Rate Numbers, and the Gap Between Filed and Approved

The four approved changes each came in below what the carriers filed, by 2.9 to 4.3 percentage points (Vermont Business Magazine, August 19, 2026). BCBSVT's individual filing requested 6.5% and was approved at 2.2%; its small-group filing requested 4.5% and was approved at 1.2%. MVP's individual filing went from 7.8% to 3.9% and its small group from 9.1% to 6.2%, the smallest cut of the four. Combined, the decisions reduce 2027 premiums for roughly 67,000 Vermonters by about $24 million.

Those requests were modest by 2027 standards before the board touched them. The national median proposed increase is 15% across the 276 insurers with public 2027 marketplace filings, with a median 10% medical trend priced in, up from an 8% average in recent years, plus an estimated 4 to 6 additional points for a sicker risk pool left behind after enhanced premium tax credits expired at the end of 2025 (Peterson-KFF Health System Tracker).

Vermont's carriers filed well under that national picture before the cut, which is consistent with a smaller, heavily regulated risk pool rather than with requests padded to be negotiated down, the pattern that shows up in states like New York, where DFS cut individual-market requests 47.4%. GMCB Chair Owen Foster framed the outcome nationally: Vermont "had the second-lowest increase in ACA Marketplace benchmark premiums in the nation for 2026" (Times Argus).

What Reference-Based Pricing Replaces in the Unit-Cost Line

A conventional QHP rate filing builds its unit-cost assumption from negotiated hospital contracts: a base allowed amount per service, escalated by whatever increase the carrier and hospital system agreed at the last contract renewal, then trended forward for utilization and mix shift. Act 68 replaces the negotiated escalator with an administered one, directing GMCB to establish maximum reimbursement amounts "as a percentage of the Medicare reimbursement for the same or a similar item or service, or on another benchmark, as appropriate," no later than hospital fiscal year 2027.

That splits a carrier's trend in two. A book with even a partial share of claims reimbursed at an administered Medicare multiple no longer has a single trend rate. It has a blend of reference-priced services tracking the CMS annual fee-schedule update, typically low single digits, and negotiated services still tracking hospital contract escalators running well ahead of the 10% national median. Getting that mix wrong is the specific mispricing risk: overestimating how much of the book migrates in year one, or underestimating how quickly hospitals push volume or acuity toward services the benchmark does not yet cover.

Vermont is not writing on a blank slate. Montana's state employee health plan adopted reference-based pricing in 2016 at 234% of Medicare for all hospital inpatient and outpatient services, generating an estimated $47.8 million in savings from fiscal 2017 through 2019, and its newer Blue Cross Blue Shield arrangement caps reimbursement at 200%, stepping down to 180% by 2026 (National Academy for State Health Policy). Against RAND's national commercial average of 254% of Medicare in 2022, with outpatient facility charges at 279%, that band is a concrete reference for where a Vermont multiple could land.

The board has already made the same substitution once, at a one-year horizon. It required BCBSVT's filing to use hospital cost assumptions reflecting the board's own FY27 Hospital Budget Guidance and recent hospital-budget enforcement actions rather than the carrier's contract-derived ones. The budget-guidance directive overrides this year's hospital-cost trend pick; the reference-pricing order overrides every future one. Act 68's scope is statewide across the commercial market rather than a single employer plan.

Balance Billing, and a Capital Position Rebuilt on Rate Adequacy

The mechanism's most-cited failure mode is balance billing. When a hospital does not accept the administered price as payment in full, it can bill the enrollee for the difference between its charge and the reference price. Montana largely avoided that because a single concentrated purchaser had leverage to negotiate hospitals into the arrangement rather than impose it; a statewide commercial mandate has no equivalent dynamic built in, which is the practical reason implementation runs through multi-year rulemaking rather than one order.

For a reserving actuary that is a new claims-liability line. Disputed balance-billing claims, where a hospital disputes the reference price and a member disputes the resulting bill, sit in appeals and negotiation for months rather than resolving at the speed of an adjudicated claim, and carriers elsewhere have generally needed one to two years of experience before that reserve component stabilizes into a predictable percentage of paid claims. The FY2027 statutory deadline is a shorter runway than that. GMCB paired the order with a directive that carriers examine what they pay out-of-state hospitals, since a Vermont-only benchmark does nothing for enrollees crossing into New Hampshire, New York or Massachusetts.

The margin question is sharper for BCBSVT than for MVP. Its risk-based capital ratio closed 2024 at 214%, the lowest in decades against a company target range of 500% to 700% that had held for over a decade, and AM Best downgraded the carrier twice that year (VTDigger, May 2025). On July 23, 2026, four weeks before this decision, AM Best revised the outlook to positive, citing improvement "supported by more-favorable regulatory rate outcomes, which enhanced pricing adequacy" (AM Best via BusinessWire).

The approved 2.2% is still an increase rather than a reduction in level, and the board tied the smaller number to controlling hospital costs rather than to insurer margin. But a capital position rebuilt substantially on rate adequacy is more exposed to a regulator cutting the next filing than one rebuilt on underwriting improvement the carrier controls directly, and BCBSVT carries that exposure into a transition whose unit-cost effect on its own book stays unknown until the benchmark multiple is set.
