Colorado Senators Michael Bennet and John Hickenlooper issued a joint statement regarding what their offices say is an "unacceptable" decision by Children's Hospital Colorado to go out-of-network for patients on TRICARE.TRICARE is the healthcare plan used by active duty members of the military, their families and veterans. You can read the senators' joint statement below: Military families across the West rely on Childrens Hospital Colorado especially those with very ill or medically fragile children. Service members children deserve the best medical care available, and the possibility that Childrens Hospital Colorado would be out-of-network for TRICARE users on January 1st is unacceptable. We call on TRICARE and CHCO to come to the table, ensure fair reimbursement rates, and fulfill their duty to military families to provide access to the health care they need.The call from state leaders comes after the Defense Health Agency restructured TRICARE reimbursement amounts last October. According to Children's Hospital Colorado's website, they filed a legal challenge to those changes, but that failed in April of this year. WATCH: Children's Hospital loses legal battle against Department of DefenseAccording to Hickenlooper and Bennet's offices, one in five patients at Children's Hospital Colorado pays with TRICARE. Children's Hospital Colorado estimates the change will cost them $17 million in revenue this year.A spokesperson with Children's Hospital Colorado shared the following statement Tuesday with News5: "The statement that has been shared with media may be confusing for families. Childrens Hospital Colorado is not fully going out of network with TRICARE as most people would understand that term. However, we have been and continue to be in active negotiations that will impact our network status with TriWest Healthcare Alliance (TriWest), which will take over as the TRICARE West Region administrator on Jan. 1, 2025.    Our priority at this time is notifying impacted families of this situation and providing answers to questions and concerns we know they will have about our network status and how it impacts their care. This information will be and has at all times been planned to be communicated as soon as possible to families.  That date was and continues to be on Wednesday, Dec. 18. For the past 18 months, we have engaged with Senators Bennet and Hickenlooper, bipartisan members of the Colorado House delegation; members of Congress; and childrens hospitals across the country to actively advocate on the issue of and military kids' access to care. We are grateful for the efforts of our members of Congress. Because this issue is related to federal funding for military families, members of Congress are integral to finding a solution and ensuring continued access to pediatric specialty care for our patients."_______Watch KOAA News5 on your time, anytime with our free streaming app available for your Roku, FireTV, AppleTV and Android TV.
