Report Overviews

The U.S. hospital emergency department market size was valued at USD 146.6 billion in 2021 and is expected to expand at a compound annual growth rate (CAGR) of 5.7% from 2022 to 2030. The major factor driving the growth of this market includes a high number of visits to hospital Emergency Departments (EDs) and the availability of insurance. According to CDC, there are approximately 130 million ED visits in the U.S. each year. Approximately 22% of adults aged 18 and over visited EDs in 2019. Around 60% of the emergency care was provided during non-business hours, making the non-availability of less expensive options an important factor contributing to the high number of ED visits.

Hospital EDs provide treatment for various indications such as cardiology, neurology, gastroenterology, infectious diseases, and psychiatry. Increasing the incidence of these conditions is rising the number of ED visits. Furthermore, the growing geriatric population in the U.S. is favoring the market, as the elderly often require urgent medical interventions. Many hospitals are adopting advanced technologies and tools, such as Artificial Intelligence (AI), to provide improved diagnosis and to expedite routine procedures, such as devising treatment plans and prescriptions for patients. The COVID-19 pandemic increased the adoption of telehealth in hospitals to multiple folds. The use of telehealth is helping the hospital to reduce waiting time and overcrowding in the EDs.

Medicare and Medicaid offer insurance for emergency health services. According to CDC, over 40% of ED visits by adults over the age of 65 are by ambulance, which is covered under Medicare Part B. Part B Medicare also covers air ambulance trips by helicopter or airplane if care is necessary. Medicare Part A covers a portion of the cost if the patient enters the emergency room and is admitted as an inpatient, while Medicare Part B covers the portion of the cost if the patient receives care from a doctor but is not admitted as an inpatient. Favorable reimbursement for ED services is contributing to the growth of the market for U.S. hospital emergency departments.

Pandemic Impact

Post COVID Outlook

Decline in the number of patients attending hospital EDs in the U.S. was observed in the initial few months of the pandemic. According to CDC pre-pandemic 2019 data, 12% of ED visits were for children which declined to 6% during the COVID-19 pandemic.

In response to the pandemic, many hospitals started and will continue to offer virtual consultations to patients. This is expected to have a positive impact on market growth in the coming year. For instance, The New York-Presbyterian/Weill Cornell Medical Center (NYPWC) started using telemedicine in its ED to reduce wait times.

The decline in ED visits was largely due to social distancing norms and restrictions on movement, which resulted in millions of dollars in revenue loss. Visits decreased from a mean of 2.1 million per week (Mar 31 to Apr 27, 2019) to 1.2 million per week (Mar 29 to Apr 25, 2020), according to National Syndromic Surveillance Programs.

Signs of recovery in emergency rooms are aided by a recent return of activity, with hospitals witnessing an increase in the number of surgeries. As the number of surgical procedures is growing, healthcare organizations are adopting a flexible and cost-effective model to meet turnaround in demand.


Various measures are taken to expand EDs to accommodate more patients are expected to help in addressing the problem of ED overcrowding. For instance, in November 2019, a not-for-profit hospital, Augusta Health, expanded its ED capacity, almost doubling its size, to include 48 treatment rooms.

Insurance Type Insights

The private and others segment dominated the market for U.S. hospital emergency departments and accounted for the largest revenue share of 53.0% in 2021. The segment is anticipated to witness substantial growth over the forecast period owing to the increasing number of commercial insurance providers and rising disposable income. For instance, a study conducted by a researcher at the University of North Carolina found that from 1996 to 2015, private insurance providers paid more for ED visits than Medicare or Medicaid.

Some private payers use value-based care strategies to reduce ED visits and hospitalizations rather than cutting coverage. Humana, for example, used value-based care models in Medicare Advantage plans, which resulted in fewer ED. Preventive screenings, collaboration with care teams, and effective management of chronic illnesses are all components of a value-based care model that can help reduce the number of emergency room visits. This is expected to boost the growth of the private payers' segment.

The Medicare and Medicaid segment held a significant share in the market for U.S. hospital emergency departments. This can be attributed to the high number of beneficiaries covered under Medicare. According to CMS, it is estimated that around 61.5 million Americans are enrolled in Medicare in 2021. Out of these 3.8 million were new enrollees. These total beneficiaries include 49% people between the ages 65 and 74 followed by 26% between75 84, 14% under age 65, and 11% are 85 or older.        

Condition Insights

The infectious conditions segment dominated the U.S. hospital emergency department market and accounted for the largest revenue share of 37.4% in 2021. This can be attributed to an increasing number of ER visits during flu season.  According to CDC National Hospital Ambulatory Medical Care Survey, in 2018, fever and cough accounted for a total of 5,837,000 and 4,955,000 emergency visits, respectively, in the U.S. The segment is projected to witness the highest CAGR of 6.1% during the forecast period owing to the high transmissibility of infectious diseases.

Significant increases in the number of motor vehicle accidents and increasing incidence of spinal cord injury, TBI, unintentional falls, and concussion are expected to drive the growth of the traumatic conditions segment. Traumatic Brain Injury (TBI) is a major cause of disability and death in the U.S. As per the National Hospital Ambulatory Medical Care Survey, there were 0.3 million ED visits due to accidents and 35 million ED visits due to injury in the U.S. This is likely to favor segment growth.

On the other hand, gastrointestinal and cardiac conditions segments are expected to grow at a moderate rate in the market for U.S. hospital emergency departments during the forecast period. According to Nationwide Emergency Department Sample, in 2018, a total of 7.07 million and 3.6 million ED visits took place due to diseases of the digestive and circulatory systems, respectively. The rising burden of digestive and cardiac diseases in the U.S. is likely to favor the growth of both segments.
