Critical Access Hospitals: What They Are and Why They Matter
Critical Access Hospitals (CAHs) play a vital role in the American healthcare system, providing essential medical services to rural and remote communities. Understanding what makes these hospitals unique can help patients in rural areas make informed healthcare decisions.
What Is a Critical Access Hospital?
A Critical Access Hospital is a designation given by CMS to small, rural hospitals that meet specific criteria. The CAH program was created in 1997 to reduce the financial vulnerability of rural hospitals and improve access to healthcare in underserved areas.
Requirements for CAH Designation
To be designated as a Critical Access Hospital, a facility must meet several criteria:
- Location: Located in a rural area or treated as rural
- Distance: More than 35 miles from the nearest hospital (or 15 miles in mountainous terrain or areas with only secondary roads)
- Bed limit: No more than 25 inpatient beds
- Length of stay: Average length of stay must be 96 hours or less for acute inpatient care
- Emergency services: Must provide 24/7 emergency care services
- State designation: Must be designated by the state as a CAH
How CAHs Differ from Regular Hospitals
- Size: CAHs are smaller, with 25 or fewer beds versus hundreds at larger hospitals
- Payment: CAHs are reimbursed by Medicare on a cost-based system, receiving 101% of reasonable costs rather than the standard prospective payment
- Services: CAHs provide essential services but may not offer specialized care, often transferring patients to larger facilities for complex procedures
- Staffing: CAHs may have fewer specialists but often have dedicated staff who know the community well
- Quality reporting: CAHs participate in some but not all CMS quality reporting programs
Services Typically Offered by CAHs
- Emergency department care (24/7)
- Basic inpatient services for short stays
- Laboratory and radiology services
- Primary care and outpatient services
- Swing bed program (using beds for acute or skilled nursing care as needed)
- Telehealth connections to specialists at larger hospitals
The Importance of CAHs
There are approximately 1,350 CAHs across the United States, representing about 25% of all hospitals. They serve as healthcare lifelines for rural communities by:
- Providing emergency care within a reasonable travel distance
- Serving as major employers in their communities
- Offering preventive care and chronic disease management
- Connecting patients to specialists through telehealth and transfer agreements

Important
This article explains how hospital quality data works and is for general information only. It is not medical advice and must not be used to decide whether to seek, delay or refuse care — that is a decision for you and a clinician who knows your situation.
CMS quality measures describe care delivered during earlier reporting periods and are refreshed roughly quarterly. A hospital's staffing, services and performance can change well before the published numbers do.
