Read this carefully. The chargemaster is the hospital’s starting price; very few patients actually pay this amount, but it’s often the basis for self-pay billing before discounts. Cash-pay is what the hospital accepts when paid in full at time of service. Median commercial is what insurance plans typically pay (the actual rate on your EOB depends on your specific plan). Medicare is the federally-set baseline.

Quality measures

CMS publishes these measures quarterly through the Care Compare program. Each measure is risk-adjusted where applicable so hospitals serving sicker patients aren’t penalized for their case mix. Values shown are this hospital’s reported numbers; “Not reported” means the case volume was too low for the figure to be statistically meaningful.

Mortality

30-day risk-standardized death rates for common admission types — tracked by CMS as a hospital-level outcome measure. Lower numbers are better; CMS adjusts for case mix so hospitals serving sicker patients aren't penalized.

Common questions

How does CMS rate WATERBURY HOSPITAL?

WATERBURY HOSPITAL carries a 3 of 5 overall hospital rating from the Centers for Medicare & Medicaid Services as of 2026-04-29. The rating combines mortality, safety, readmission, patient experience, and timely-care measures into a single score, refreshed quarterly.

Is WATERBURY HOSPITAL a non-profit hospital?

WATERBURY HOSPITAL is registered with CMS as Proprietary. ACA §501(r)'s charity-care requirement applies to non-profit hospitals; for-profit and most government hospitals are governed by other rules.

How do I dispute a bill from WATERBURY HOSPITAL?

Every patient has federal rights regardless of which hospital sent the bill: (1) request an itemized statement (HIPAA §164.524), (2) receive a Good Faith Estimate before scheduled care (No Surprises Act, 2022), (3) dispute amounts billed beyond the agreed-upon estimate or without prior consent, and (4) apply for charity care if the facility is a 501(c)(3) non-profit (ACA §501(r)). Side-by-side comparison of your itemized bill against Medicare benchmarks is the standard first step in any review.

How fresh is this data?

Quality and pricing data on this page comes from the CMS Care Compare program, refreshed quarterly. Last updated: 2026-04-29. The hospital roster (name, address, ownership) refreshes on the same cadence. Source files are linked from /data-sources, and a "Report inaccuracy" link at the bottom of this page sends a correction request that we review as quickly as we can.

P.P.S. Even though this isn’t a non-profit hospital, you still have federal rights: itemized statement (HIPAA §164.524), Good Faith Estimate (No Surprises Act), and the right to dispute amounts billed without prior consent. The scan drafts the appropriate letters for whichever apply.
