    The PCP is the member's main point of contact for care. Members can choose from different provider specialties for their PCP, including:

    • Family medicine
    • Geriatric medicine
    • General practice
    • Gynecology
    • Internal medicine
    • Adolescent medicine
    • Naturopathy
    • Pediatrics

    Note: PCP provider types can be a doctor of medicine (MD), a doctor of osteopathic medicine (DO), an advanced register nurse practitioner (ARNP), a nurse practitioner (NP), or a physician assistant (PA).

    HMO members and their dependents can choose an in-network primary care provider (PCP) using the Find Care tool. They can use the Find Care tool to change their PCP at any time. Users will land on the PCP page after clicking the PCP notification call to action. From here, users may “Change PCP” or “Go to PCP details.”

    HMO members and their dependents will need to select a primary care provider (PCP). If they don’t select a PCP, Premera will suggest a PCP for them. The member-PCP relationship is an important part of the Premera HMO Core Plus plan because the PCP will guide the member and their dependents through their healthcare needs.

    Check to see if a provider is in the Sherwood HMO network.

    How does Premera Blue Cross HMO choose a PCP for a member?

    The process starts with a review of a member’s claims history to identify if the member has received care from a particular PCP in the past. If the review does not suggest an existing PCP relationship, a PCP will be suggested based on:

    • Location (nearest to member’s home address)
    • Type of provider
    • Specialty
    • Gender

    Note: Suggested PCPs are in the Sherwood HMO network and are currently accepting new patients. View Guide to HMO Core Plus member PCP search and select.

    Sherwood HMO Network Provider Directory

    Providers and members have access to the Sherwood HMO Network provider directory to help them pick the right provider for their needs. 

    Changing/Selecting a PCP

    If a member chooses to change or manually search for a PCP, they will be directed to the Changing/Selecting a page.


    An HMO member is required to have a referral for specialty services from their PCP for a specialist or PCP. The referral tool is available in Availity to submit a request for specialty services.

    There are certain services that are direct access and don't require a referral. View direct access services list.

    If a referral is not provided and a member chooses to receive services from providers or facilities, those services will not be covered under this plan. The member will be responsible for 100% of the cost for these services and any amount will not apply to their out-of-pocket maximum, except services required by federal or state law. View Availity Referral Tool Quick Reference Guide.

    Prior Authorizations

    A service may require prior authorization. If the provider doesn’t get a prior authorization, it could result in a payment penalty to the provider. When a service requires pre-service review, there isn't a penalty, but Premera will hold the claim and ask for medical records. Prior authorizations can't be submitted by phone. Prior authorizations can be submitted through Availity.

    Behavioral Health Navigator

    The pandemic has brought mental health even further into the spotlight and now it’s become a critical topic. To help our members find the care they need, and to assist providers to ensure that their patients are getting help, we offer a navigation service. With one phone call to our HMO Plus Team number (844-PBC-HMO1 or 844-722-4661), Premera can help a member find a provider that meets their needs and is accepting patients.

    Urgent and emergency care

    Our HMO is an in-network offering only. However, when an urgent situation arises an HMO member can utilize urgent care and emergency care anywhere in the United States. Emergency care is explained from Premera’s contract team as:

    • “Examination and treatment as required to stabilize a patient to the extent the examination and treatment are within the capability of the staff and facilities available at a hospital. Stabilize means to provide medical, mental health, or substance use disorder treatment necessary to ensure that, within reasonable medical probability, no material deterioration of an emergency condition is likely to occur during or to result from the transfer of the patient from a facility; and for a pregnant member in active labor, to perform the delivery.”
    • “Ambulance transport is needed in support of the services above.”

    Urgent care comes to the member with Dispatch Health

    Members can avoid wait times for urgent care with Dispatch Health, a provider group contracted with Premera.  

    • At the cost of a co-pay, members can have Dispatch Health come to their home or work.
    • They provide on-demand, qualified, acute care to keep patients out of the hospital seven days per week, 8 a.m. to 10 p.m. Pacific Time.
    • A provider, case manager or patient can request care via phone or web.
    • To eliminate barriers to getting care and the need for transportation, Dispatch Health sends a care team directly to a patient’s home.
    • Once on the scene the care team can provide 60-70% of care available in the ER
    • Dispatch Health  collaborates closely with the patient’s primary care provider for close follow up if needed.

    Virtual care

    Premera believes in helping members at all points of their care journey. There are partnerships in place with many best-in-class organizations to help members live healthier lives. To that end, HMO members have access to virtual care vendors until clinic-based providers can offer 24/7 care. Since this care is accessible through MyCare. Sherwood HMO offeres access to the following care providers:

    • 98point6
    • 24-Hour Nurse line
    • Doctor On Demand

    Pharmacy Services

    HMO pharmacy services include dedicated support from the HMO Plus Team and proactive outreach focusing on providing the right care at the right time. Premera pharmacists are available for clinical consultations with members and providers to answer any medication questions they may have. Most HMO plans will require the use of exclusive home delivery using the Express Scripts mail-order pharmacy for maintenance medications it’s designed to be a cost saving strategy for members.

    Core pharmacy programs:

    • Low copays for Tier 1 and 2 drugs
    • Dedicated support to members pharmacy needs


    • Allows for the most restrictive and high-value options for medications through medication exclusions and unique tiering options
    • Exclusions: reduce cost of high-cost, low-value drugs, and steer members to lower cost alternatives in select classes
    • Tier 4 has non-preferred generics, brand, and specialty medications to reduce use of high-cost, low-value medications

    Dental care

    HMO plans cover certain medical services that are provided by a dental provider, which are listed as covered under the medical plan, but dental services are offered separately from HMO.

    Beginning Jan 1, 2023, with the HMO medical product, an employer can select a Premera branded dental plan. If the employer selects a dental plan, their employees will have dental coverage. If an employer doesn’t select a Premera Blue Cross dental plan, then the member will not have dental coverage through Premera.
