Virginia’s SB 536, passed by the General Assembly on March 14, 2026, requires every Virginia hospital or health system that self-insures or maintains retained-risk arrangements for medical malpractice to disclose standardized claims data to the legislature. The first filing is due September 1, 2026, covering the 2025 calendar year.
The bill started as something far more aggressive. Sen. Mark Obenshain’s original version would have doubled Virginia’s medical malpractice damages cap from roughly $2.7 million to $6 million, expanded the statute of limitations, and allowed prejudgment interest above the cap. The General Assembly stripped those provisions in the final days of the session and replaced them with a data-collection mandate. The bill contains an automatic sunset clause triggered by the passage of new damages caps, a signal that the legislature views this as an intermediate step.
Who it affects
Self-insured hospital systems in Virginia that maintain captive insurance, risk retention arrangements, or other retained-risk structures for medical malpractice. Commercial malpractice insurers must file parallel disclosures, enabling direct comparison between retained and transferred risk.
The required data includes the number of physicians and providers covered, claims activity, malpractice expenditures, and total liability costs as a percentage of patient service revenue. Both self-insured and commercially insured entities must separately report all verdicts exceeding the statutory cap. Subsequent annual filings shift to a March 31 deadline beginning in 2027.
The reserve mechanism: case adequacy and expected loss ratio
The September disclosure deadline creates two layers of reserve exposure for hospital professional liability programs.
First, the data aggregation itself. Many self-insured hospitals track claims through a mix of TPA reports, captive manager summaries, and internal spreadsheets. Assembling this data into a standardized filing will force hospitals to reconcile those sources, potentially surfacing case reserve inadequacy that informal tracking masked. Hospitals that discover gaps between their internal claims records and what the filing requires should treat the finding as a case adequacy diagnostic.
Second, the cap-increase signal. Virginia’s current med-mal cap is $2.7 million for claims arising between July 1, 2025 and June 30, 2026, with scheduled $50,000 annual increases to a $3 million ceiling by 2031. If the disclosure data supports a cap increase toward the $6 million level the House originally proposed, severity exposure on open and future Virginia claims would rise materially. Hospital captives that currently set case reserves at or near the statutory ceiling would need upward revisions to both case incurred and IBNR. Even before a cap change passes, the probability-weighted severity shift should be reflected in expected loss ratios on prospective policy years.
What this means for your next review
Hospital risk officers with Virginia exposure should begin the data aggregation now rather than waiting for summer. Use the exercise as a dry run for case adequacy: if your internal claims totals do not reconcile cleanly, that is information your actuary needs before your next reserve study. Separately, ask your actuary to model a severity scenario where the cap doubles. Stakeholders expect the legislature to take up a cap-increase bill in the January 2027 session, and the disclosure data will be the evidentiary foundation.
