Kaiser's Integrated System
Kaiser operates its own:

Employed physicians in all specialties
On-site pharmacies and labs
Urgent care facilities
Location Matters: Kaiser works best if you live near Kaiser facilities. Check coverage in your area before enrolling.
Blue Shield's Provider Network
Blue Shield contracts with independent providers:
Large network of hospitals and doctors
Multiple network tiers (Trio, Tandem, etc.)
PPO plans offer out-of-network coverage
Keep your existing doctors if they're in-network
Cost Comparison
Both carriers sell Covered California's standard plan designs, so what you pay when you use care depends more on the metal tier than on the carrier. These are the standard 2027 plans:

On the standard Bronze 60 plan the deductible is waived for your first three non-preventive visits of the year combined (office, urgent care and outpatient mental health visits). After that, the deductible comes first.
Gold and Platinum come in copay and coinsurance designs, and a few benefits can differ by carrier, so check the plan's own summary. Premiums differ by carrier, age and area: the quote form prices both for you.
