At John Muir Health, you can be sure you'll always get the same high-quality, compassionate care no matter what HMO plan you choose. But, you must carefully select a medical group and a primary care physician or doctor (PCP) from that medical group.

Many doctors belong to more than one medical group — making it easy to accidently affiliate with a group you don't intend to. In order to use John Muir Health services, you must ensure that the Provider ID number you select is the one that is for the John Muir Physician Network.

In order to enroll, you may need to fill in the provider ID number for your preferred doctor. You can find this number on your health insurance plan's website. For detailed instructions to navigate your HMO's site, select the link below.

  • Aetna HMO
  • Anthem Blue Cross HMO
  • Blue Shield of California HMO
  • CIGNA HMO
  • HealthNet HMO
  • PacifiCare HMO
