At Blue Shield of California Promise Health Plan, we understand the importance of developing and maintaining solid relationships with healthcare providers, as well as the barriers that underserved California communities face in accessing healthcare services. 

Through our Medicare, Medi-Cal, and Cal MediConnect plans and provider networks, we strive to ensure that Californians have access to quality, affordable care.

We think the same way you do

At Blue Shield Promise, you'll find a level of understanding and communication that helps both your practice and your patients. Since our executive leadership includes physicians, we value a “patients first” philosophy of care. We strive to work closely with you, be responsive, and understand the challenges your practice or provider organization faces in providing care. Our goals include providing programs and opportunities that demonstrate our dedication to supporting quality improvements in health care.

Blue Shield Promise provider networks

Blue Shield Promise’s networks comprise more than 7,000 physicians, 80 hospitals, and hundreds of ancillary medical professionals. As a mixed-model HMO health plan, Blue Shield Promise contracts with individual physicians, and with independent physician associations (IPAs) and medical groups on a capitated basis. Under the IPA/medical group arrangements, operational functions are delegated, with Blue Shield Promise providing oversight.

Our mixed model also offers an opportunity for independent physicians and other provider types to contract directly with Blue Shield Promise under flexible reimbursement methodologies.
