Top 10 hospitals and IDNs by total facility area
Definitive Healthcare tracks more than 9,100 distinct hospitals and IDNs across the U.S. in our Atlas Dataset. Using our HospitalView product, we compiled a list of the facilities ranked by total facility area.
What is total facility area?
Measuring the total facility area is one method healthcare organizations can use to determine the size of a specific facility. Total facility area indicates the number of square feet in an organization’s fixtures and facilities—how physically large the hospital or health system is. Bed count is another method of determining facility size, as it generally indicates how many patients can be served at a time. You can learn more about bed count by reading our Healthcare Insight on which U.S. hospitals have the highest bed counts.
Knowing the total facility area is beneficial because it gives insight into healthcare organizations’ costs, operations, and governance. Healthcare organizations can learn how to use space better by understanding these factors. In turn, optimal space utilization inspires organizational advancement. Additionally, companies can discover new targets for products and services by having insight into which facilities may have the space and need.

Which hospitals and IDNs are the largest?
The Creedmoor Psychiatric Hospital is the facility with the highest total facility area in 2023. Located in NY, it has a square footage of 9,358,475. HCA Healthcare is the largest IDN by total facility area. Located in TN, it has a square footage of 75,277,035.
As shown in the data above, healthcare organizations in New York appear five times across both lists and take the top spot on the hospital list, which makes sense since NY is the fourth largest state in the U.S. Tennessee also appears frequently across both lists, likely because Nashville, TN, is a healthcare hub. Major hospitals and health systems, including Vanderbilt University Medical Center, HCA Healthcare, and Community Health Systems, are all in the greater Nashville area.
What is the difference between hospitals and IDNs?
A hospital is a single institution that offers medical care. Comparatively, an IDN, or health system, is an entity that owns and operates a network of healthcare facilities, like hospitals, ambulatory surgery centers, and physician groups. Because IDNs typically encompass a large number of facilities, there are many healthcare providers within an IDN. IDNs can also have greater market influence.
