The short version. Coverage of H.583 has focused on its private equity restrictions. The provision that actually creates work for most operators is § 9773: every health care facility and every management services organization files with the Green Mountain Care Board by 1 March 2027 — including those with no outside capital, who file an attestation saying so.
What this is. A read of what a named statutory change actually requires, and by when. It is not a client engagement. Dates and section numbers come from the enacted text, cited at the foot of the page.
What was enacted
H.583 was signed 15 June 2026 and took effect 1 July 2026.
§ 9772 bars a private equity group or hedge fund involved with a Vermont health care facility from interfering with providers’ health care decisions, and from exercising or being delegated a list of operational controls.
§ 9773 is the disclosure regime, and it reaches much further than § 9772.
The filing nobody budgeted for
| Your position as of 1 June 2026 | What you file by 1 March 2027 |
|---|---|
| A private equity group or hedge fund held an ownership or investment interest | The full ownership and control report under § 9773(b) |
| None did | An attestation that the entity currently has no private equity or hedge fund ownership or investment |
There is no “not applicable” box. An owner-operated management company in Vermont with no outside investor still files — the attestation is the filing. And § 9773 keeps running: it also requires reporting when a private equity group or hedge fund later takes on or modifies an interest.
The best MSO control checklist published anywhere
Whatever your capital structure, § 9772 is worth reading as a checklist, because it is the clearest articulation any legislature has published of what improper control looks like. It names, as things that may not be controlled or delegated:
- setting clinical standards or policies, including clinical staffing levels;
- controlling the content of patient medical records;
- hiring or firing providers or clinical staff on competency grounds;
- setting payer contracting parameters;
- setting the prices charged for a provider’s services;
- coding and billing decisions;
- selecting medical equipment and supplies.
It also treats how many patients a provider sees, and how many hours they work, as interference with clinical judgment. Most management agreements call that operations.
What to do about it
- Decide whether your Vermont entity is a “health care facility” or a “management services organization” as H.583 defines them.
- Fix the 1 June 2026 snapshot — that is the date the report keys to.
- Diarise 1 March 2027 and decide which of the two routes you are on.
- Run your management agreement against the § 9772 list before you file, because filing puts it on the record.
