Urgent Care Update: Effective immediately, our Urgent Care hours are Monday–Friday, 10:00 AM–7:00 PM. We will not be open on Saturdays or Sundays. Please note: Effective August 1, our Urgent Care is no longer contracted with IEHP and cannot provide Urgent Care services to patients with IEHP coverage, regardless of who their Primary Care Provider (PCP) is. This change applies only to our Urgent Care. If you are an IEHP member assigned to a Citrus Valley Primary Care Provider, you may continue to schedule appointments with and receive care from your assigned PCP at their Primary Care office.
