About Enhanced Care
About Us
Astrana EnhancedCare offers free case management services through our enhanced care management (ECM) program for eligible Medi-Cal patients. Our case managers work closely with your medical providers, pharmacists and other specialists to support your overall health and well-being.
Our Values
Relationships First – We build strong, trusting connections between members and their care managers, so you always feel supported and never alone. Count on Us – Behind every care manager is a whole team with different expertise, working together to make sure your care is coordinated and nothing is overlooked. Whole-Person Care – We see you as more than your health needs. Your goals, values, and experiences shape your care plan. Beyond the Checklist – ECM isn’t just about tasks—it’s about truly listening, understanding, and helping you get the care and support that matters most to you. Together Toward Better Health – We partner with you every step of the way, combining medical care with social support to help you live well and thrive.
