Five CMS release snapshots
Each point is from the named download. The table shows when that care was delivered. These windows differ and are not five identical annual cohorts.

Sources and reporting dates
Current records use the CMS hospital files modified July 22, 2026 and released August 13, 2026. The four historical downloads are dated January 6, 2022; January 6, 2023; January 31, 2024; and February 19, 2025.
- CMS hospital information: provider records, service flags, and hospital types.
- CMS timely care measures: results, reporting windows, samples, and footnotes.
- CMS historical hospital archives: older snapshots.
How to read the figures
OP_18b reports the median time included discharged patients spent in the emergency department. The current measure excludes transferred patients and psychiatric or mental health patients. It is not time to see a doctor. A median means half of included visits were shorter and half were longer. A longer figure alone does not establish worse care.
“Not reported” is never treated as zero. CMS may suppress a small sample or have no usable result. Each measure has its own care dates. The state and national comparisons come directly from CMS; no local average has been made from hospital medians.
Historical and geographic limits
The charts show five release snapshots, not five equal calendar-year cohorts. Some early windows cover only nine months. Current OP_18b wording is more detailed than the older wording. Missing years stay blank, and observations are not presented as a like-for-like annual trend.
CMS may report across multiple campuses under one provider ID. City and county fields follow the CMS records and may reflect mailing locations. This directory is not a complete list of emergency entrances, a distance search, or a live queue. Check the current emergency entrance with the hospital. Missing from this directory does not by itself mean a hospital has closed.
