Children's Hospital Colorado

Children's Hospital Colorado is a nonprofit pediatric hospital located at 13123 East 16th Avenue in Aurora, Colorado, on the University of Colorado Anschutz Medical Campus. It serves as the primary teaching hospital for the University of Colorado School of Medicine and is among the largest children's hospitals in the western United States. The hospital operates 636 licensed beds and treats patients from across Colorado, the Rocky Mountain region, and beyond. It is consistently ranked among the top children's hospitals in the United States by U.S. News & World Report.

Founded in 1908 as a tuberculosis sanatorium in Denver, the hospital has grown into a complex academic medical center combining clinical care, biomedical research, and training for pediatric healthcare professionals. Its affiliation with the University of Colorado Anschutz Medical Campus places it within one of the largest academic medical complexes in the United States. The hospital's mission includes direct patient care, community health outreach, and the training of physicians, nurses, and researchers. In January 2025, the hospital suspended gender-affirming care for patients under 18, citing concerns about potential loss of federal Medicaid funding following directives from the U.S. Department of Health and Human Services under Secretary Robert F. Kennedy Jr. The Colorado Supreme Court subsequently ordered the hospital to resume those services while litigation over the matter continued.

History

Children's Hospital Colorado traces its origins to 1908, when it was founded in Denver to provide specialized care for children suffering from tuberculosis, a disease that placed an enormous burden on Colorado's population in the early twentieth century. The institution operated under the name Rocky Mountain Sanatorium in its early years, reflecting its original focus on respiratory illness. As tuberculosis rates declined and the scope of pediatric medicine broadened, the hospital expanded its services to cover a full range of childhood conditions and moved toward becoming a general pediatric hospital.

The hospital's affiliation with the University of Colorado deepened substantially in the early 2000s when the University of Colorado Health Sciences Center relocated its campus to Aurora. Children's Hospital Colorado moved alongside it, establishing its current presence on the Anschutz Medical Campus. This alignment formalized the hospital's role as an academic medical center and gave its clinical programs direct access to the university's research infrastructure. The partnership has supported studies into childhood cancer, diabetes, genetic disorders, and rare diseases, among other conditions.

Infrastructure investment has continued into the twenty-first century. The hospital completed a major expansion with the addition of a new patient care tower, increasing its capacity to treat the most complex pediatric cases referred from across the region. These facilities include advanced imaging centers, dedicated surgical suites, and inpatient units designed for children with serious or chronic illnesses. The Anschutz Medical Campus setting also allows the hospital to participate in collaborative research with other institutions co-located there, including the University of Colorado Hospital and the CU Cancer Center.

In January 2025, Children's Hospital Colorado suspended gender-affirming care for patients under 18, citing concerns that continued provision of such services could jeopardize its federal Medicaid funding in light of directives from the U.S. Department of Health and Human Services under Secretary Robert F. Kennedy Jr. The decision drew immediate legal challenge from patients and families. The Colorado Supreme Court subsequently ordered the hospital to resume care while the litigation continued, ruling in favor of patients who argued the suspension violated their rights under Colorado law. The episode drew national attention and raised broader questions about the relationship between federal funding mechanisms and hospital autonomy in delivering care.

Gender-Affirming Care Controversy (2025)

In early January 2025, Children's Hospital Colorado announced the suspension of gender-affirming care services for patients under 18, becoming one of several major pediatric institutions across the country to do so in the weeks following the change in federal administration. Hospital leadership stated that the decision was driven by concerns that the U.S. Department of Health and Human Services, under Secretary Robert F. Kennedy Jr., could withhold federal Medicaid funding from hospitals that continued to provide such services. Because Medicaid reimbursements represent a substantial share of the hospital's revenue and fund care for many of its most vulnerable patients, leadership characterized the decision as a financial necessity rather than a medical or ethical judgment.

The scope of the suspension prompted significant public concern, in part because the affected care extends well beyond treatment of transgender and nonbinary youth. Gender-affirming medical treatments, including puberty blockers and hormone therapies, are used across a range of pediatric conditions. Puberty blockers, for example, are a standard treatment for precocious puberty, a condition in which children begin puberty abnormally early. Hormone therapies are also used to manage hormonal imbalances arising from chemotherapy, to treat endometriosis, and to address other endocrine disorders in children and adolescents. Patients relying on these treatments for conditions unrelated to gender identity were among those affected by the suspension, and their families were among those who brought legal challenges.

The Colorado Supreme Court took up the matter on an expedited basis and ordered Children's Hospital Colorado to resume gender-affirming care services while the underlying litigation proceeded. The court found that patients had a colorable claim that the suspension violated their rights under Colorado law, which explicitly protects access to gender-affirming care. The case drew attention nationally as an early test of how state-level patient protections would interact with federal funding threats in the area of gender-affirming medicine. The broader question of whether hospitals can be compelled by federal agencies to restrict services that state law protects remained unresolved as litigation continued.

The controversy highlighted a tension at the center of hospital governance: institutions that depend heavily on federal reimbursement may face pressure to conform to federal policy even where that policy conflicts with state law or with the clinical judgments of their own physicians. Colorado law had previously made the state a legal haven for gender-affirming care, and Children's Hospital Colorado had been a provider of such services for gender-diverse youth as well as for patients with a variety of endocrine and hormonal conditions. The January 2025 suspension, and the court order requiring its reversal, underscored how quickly that framework could be disrupted by changes in federal enforcement posture.

Geography

Children's Hospital Colorado is situated in Aurora, a city in Arapahoe County approximately 12 miles east of downtown Denver. Its specific address, 13123 East 16th Avenue, places it within the Anschutz Medical Campus, a concentrated healthcare and research district that also houses the University of Colorado Hospital, the CU School of Medicine, and several research institutes. Aurora itself is Colorado's third-largest city, with a population exceeding 380,000, and it borders Denver to the east and southeast.

The campus is accessible from Interstate 225, which connects Aurora to both Interstate 25 and Interstate 70. The University of Colorado A Line commuter rail, operated by the Regional Transportation District, stops at the nearby Peoria Station, providing a direct connection to Denver Union Station and Denver International Airport approximately 25 miles to the northeast. RTD bus routes also serve the campus directly. For patients and families traveling by air, the airport's relative proximity makes Denver a practical entry point for families arriving from rural Colorado, Wyoming, and other parts of the Mountain West.

The surrounding neighborhood includes a mix of medical facilities, academic buildings, and residential areas. Green spaces near the campus include the High Line Canal Trail system, which runs through the eastern Denver metro area. Aurora's broader geography incorporates the Aurora Reservoir and Cherry Creek State Park, both within a short drive of the hospital.

Services and Specialties

Children's Hospital Colorado provides care across more than 30 pediatric specialty areas, including cardiology, oncology, orthopedics, neurology, gastroenterology, and neonatology. Its level IV neonatal intensive care unit is one of the largest in the region. The hospital also operates a pediatric trauma center and a dedicated children's emergency department that treats tens of thousands of patients annually.

Research and clinical care intersect prominently in the hospital's specialty programs. In 2025, Children's Hospital Colorado opened the first multidisciplinary clinic in the United States dedicated to treating a rare neurological disorder, bringing together specialists from multiple disciplines to coordinate care for patients who would otherwise need to see providers at several different institutions. The hospital has also developed nationally recognized programs in cancer treatment, publishing research on childhood leukemia and solid tumor management through its affiliation with the CU Cancer Center.

The hospital's mental and behavioral health programs have expanded significantly in recent years in response to a documented rise in pediatric mental health crises across Colorado and the country. It operates inpatient psychiatric units for children and adolescents, as well as outpatient programs embedded within its primary care network. In 2025, Children's Hospital Colorado and Healthier Colorado jointly launched Mind Our Future Colorado, an initiative aimed at elevating child and youth mental health as a priority issue in the 2026 gubernatorial race and pressing candidates to commit to concrete policy action on pediatric mental health funding and access. Children's Hospital Colorado also runs a network of urgent care clinics and specialty outpatient locations across the Denver metropolitan area, extending access beyond the main Aurora campus.

Gender-affirming care has been a notable part of the hospital's services for gender-diverse youth as well as for patients with a range of other medical conditions. Such care encompasses puberty blockers, hormone therapies, and mental health support. These treatments are used not only for transgender and nonbinary patients but also for children with precocious puberty, hormonal imbalances arising from chemotherapy or other treatments, endometriosis, intersex conditions, and certain other endocrine disorders. The January 2025 suspension of these services, and the court order requiring their resumption, is covered in detail in the Gender-Affirming Care Controversy section above.
