UnitedHealthcare of California Ancillary Care Provider Referral Directory

Our California Referral Directories are updated each month to help you and your staff refer UnitedHealthcare of California SignatureValue® and UnitedHealthcare® Medicare Advantage HMO members to in-network ancillary providers. Online care provider directories should be used for all other health plans.

Please Report Inaccurate Directory Listing Information
If a care provider listed in California Referral Directories is no longer in business, no longer serving a particular county, or has a change in address or phone number, please contact your Physician Advocate so that we may contact the care provider and update the directory accordingly.

California Ancillary Referral Directory
The California Ancillary Referral Directory is a listing of all contracted care providers in California, regardless of division of financial responsibility and risk.

Medical groups with contracts stating that durable medical equipment (DME) is the Health Plan Risk on their Division of Financial Responsibility (DOFR), must use an in-network provider in UnitedHealthcare’s contracted network.  

As of April 1, 2022,  DME is no longer capitated to an exclusive provider.  Requests may be sent to any in-network provider in UnitedHealthcare’s contracted network.

For referrals to physical therapy, occupational therapy and speech therapy providers, visit for a directory of providers in your area.

Members of Medicare Advantage Plans for eligible counties should be referred to hiHealthInnovations for hearing aid services. If you have questions, please call hiHealthInnovations at 855-523-9355.
