Community Health Group in Chula Vista's Eastlake corridor is a nonprofit managed-care health plan founded in 1982, serving nearly 400,000 Medi-Cal and Medicare beneficiaries across San Diego County from its Fenton Street headquarters. CHG operates the largest Medi-Cal provider network in San Diego County, connecting members with primary care, behavioral health, pharmacy benefits, and specialty referrals through contracted providers that include psychiatric practices such as KMG Psychiatry. Plan offerings span standard Medi-Cal managed care, a Dual Special Needs Plan for members eligible for both Medicare and Medi-Cal, and a Chronic Special Needs Plan for beneficiaries managing complex long-term conditions. CHG's 300-plus employees process claims with an average turnaround of 15 days, delivering culturally and linguistically appropriate member services in a county where the health plan draws its credentialed workforce from local training pipelines at institutions such as Pima Medical Institute - Chula Vista. The plan's network architecture routes each enrolled member through a primary care physician gatekeeper model with integrated behavioral health carve-in, pharmacy benefit management under the Medi-Cal Rx formulary, and durable medical equipment authorization processed through a centralized utilization-management team.
