Counts refer to CMS reporting records, not a complete count of physical ER entrances. VA, military, and specialist hospitals have different service or access rules. Check with the facility before travel.
Maryland and national CMS snapshots
These are published historical observations. No city or county “average wait” has been calculated from hospital medians. Patient groups and reporting periods matter when reading the values.

Before you choose a location
For an emergency
Call 911 when you need emergency help. Do not delay urgent care to compare these historical figures.
Check the entrance and type of care
CMS addresses can lag behind a move. A children’s hospital, a VA facility, or a specialist hospital may have different intake rules. Use the hospital’s contact details to confirm the current service and entrance.
What if a result is missing?
A missing figure is not zero and does not show that a facility has no emergency service. It can reflect a small sample or unavailable reporting. Read the hospital profile for the CMS note.
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.
