Blue Shield of California Is Not Anthem Blue Cross

This page concerns Blue Shield of California and the BlueShieldCA.com website. It should not be described as a combined company called “Blue Cross and Blue Shield of California.”

California members may have coverage through different Blue organizations. Check the exact company name and website printed on the current member ID card.

• Blue Shield of California card: Use Blue Shield of California contacts and BlueShieldCA.com.
• Anthem Blue Cross card: Use the Anthem contacts printed on that card.
• Another state’s Blue plan: Call the number on the member’s home-plan ID card.
• BlueCard or out-of-state care: Follow the instructions on the member ID card and Blue Shield account.

Calling the wrong Blue company can delay claim, eligibility and prior-authorization assistance.

• Plan type, such as HMO, PPO, Medicare or Medi-Cal
• Employer or Covered California information when applicable

Do not publicly post member IDs, claim numbers, dates of birth, diagnoses, medical records, prescription information, Social Security numbers, complete addresses or payment information.

1. Sign in to the Blue Shield member account.
2. Open the ID Card section.
3. Select the correct member and plan.
4. Download, print or display the card.

• ID-card help: Access or replace a Blue Shield card

Blue Shield Claims and Explanations of Benefits

An explanation of benefits, or EOB, is not necessarily a medical bill. It explains how Blue Shield processed a claim.

An EOB may show:

• The provider’s billed amount
• The negotiated or allowed amount
• Network savings
• The amount paid by Blue Shield
• The deductible applied
• Copayment or coinsurance
• The amount the member may owe
• Denied or excluded services
• Processing and reason codes

Review the EOB before paying a provider bill.

1. Confirm the patient and date of service.
2. Compare the provider’s bill with the EOB.
3. Verify whether the provider was processed as in network.
4. Review the deductible, copayment and coinsurance.
5. Check the denial or adjustment codes.
6. Confirm whether prior authorization or a referral was required.
7. Call Blue Shield and the provider when the documents do not match.

• EOB guidance: How to read a Blue Shield EOB

Provider Bill Does Not Match the Blue Shield EOB

Do not ignore a provider bill, but do not assume it is correct merely because it arrived after the EOB.

Ask the provider:

• Whether the claim was submitted with the correct member ID
• Whether a corrected claim has been filed
• Whether another insurer was listed as primary
• Whether the bill reflects the Blue Shield contracted rate
• Whether the balance is on hold during review

Ask Blue Shield:

• How the claim was processed
• Whether the provider was in network on the service date
• What amount the member is responsible for
• Whether the claim can be reprocessed
• Whether an appeal is required

Keep the bill, EOB, claim number and notes from both calls.

Denied Blue Shield Claim or Coverage Request

A denial may involve:

• A service considered not covered
• Medical-necessity criteria
• Experimental or investigational treatment
• Missing prior authorization
• An out-of-network provider
• A referral requirement
• Incorrect coding or billing information
• Eligibility or coverage dates
• Coordination of benefits
• A prescription formulary rule

Before filing an appeal:

1. Read the complete denial notice.
2. Identify the exact reason and appeal deadline.
3. Ask the provider whether the claim or authorization contained an error.
4. Obtain relevant medical records and supporting information.
5. Ask the treating clinician for a letter explaining medical necessity.
6. Follow the appeal instructions in the notice or plan document.
7. Keep proof of submission and the appeal case number.

Prior Authorization and Referral Problems

Prior authorization is approval that may be required before certain services, procedures, drugs or equipment are covered. It is not a guarantee that every claim will be paid.

For a delayed or denied authorization:

• Confirm which provider submitted the request.
• Obtain the authorization reference number.
• Ask whether clinical information is missing.
• Verify whether the service is urgent.
• Check whether a referral is also required.
• Ask the provider to respond promptly to requests for records.
• Request an expedited review when delay could seriously harm the patient’s health.

• Prior-authorization resources: Review Blue Shield authorization information

Urgent and Expedited Appeals

An expedited appeal may be available when waiting for the standard process could seriously jeopardize the member’s life, health, ability to regain maximum function or ability to manage severe pain.

The member or treating physician should:

1. Call the number on the member ID card.
2. State clearly that an expedited appeal is being requested.
3. Explain why the standard timeframe creates a health risk.
4. Submit the supporting clinical information immediately.
5. Record the date, time and case number.

Do not wait for a routine grievance response during a medical emergency. Call 911 or seek emergency care.

How to File a Blue Shield Grievance

A grievance is a formal complaint about coverage, care, access, claim handling, authorization, service quality or administration.

Blue Shield says grievances may generally be filed within 180 days of the claim decision or incident involved.

Members can:

• Call the number on the ID card
• Call 1-800-393-6130
• File through the secure member account
• Download and mail a grievance form

• Grievance information: File a Blue Shield grievance or appeal
• Member forms: Find grievance, appeal and authorization forms

For medical-service grievances sent by mail, Blue Shield currently lists:

Blue Shield of California
Attn: Member Services Grievances
P.O. Box 5588
El Dorado Hills, CA 95762-0011

Dental, vision, Medicare and Medi-Cal plans may use different forms, addresses and deadlines. Follow the instructions in the applicable plan document or denial notice.

What to Expect After Filing a Grievance

Blue Shield states that it generally:

• Sends an acknowledgement within five calendar days
• Resolves standard grievances within 30 calendar days
• Resolves qualifying expedited appeals within three calendar days

Save every letter and case number. If the issue changes or new medical information becomes available, send it through the approved secure process rather than posting it publicly.

Independent Medical Review and DMHC Complaints

Many Blue Shield health plans are regulated by the California Department of Managed Health Care.

The DMHC may assist with:

• Denied medically necessary care
• Experimental or investigational treatment denials
• Delayed authorization
• Access to doctors or specialists
• Network disputes
• Billing and copayment problems
• Coverage cancellation
• Continuity-of-care issues
• Unresolved grievances

Members normally must first file a grievance with the health plan and participate in its process for up to 30 days. Immediate DMHC assistance may be available when there is a serious threat to health or a denial involving experimental or investigational treatment.

• DMHC Help Center: 1-888-466-2219
• DMHC TDD: 1-877-688-9891
• File a complaint or request an IMR: California DMHC complaint process

California Department of Insurance Complaints

Certain insurance products issued through Blue Shield of California Life & Health Insurance Company may be regulated by the California Department of Insurance rather than the DMHC.

Review the denial letter, Evidence of Coverage or policy document to identify the regulator. Blue Shield’s grievance response should also explain the correct external-review route.

• California Department of Insurance Consumer Hotline: 1-800-927-4357
• CDI TTY: 1-800-482-4833
• File a CDI complaint: California insurance consumer help

Covered California and Blue Shield Responsibilities

For a Blue Shield plan purchased through Covered California, contact Covered California for:

• Household or address changes
• Income changes
• Citizenship or residency documents
• Financial assistance or premium tax credits
• Marketplace enrollment changes
• Marketplace cancellation
• Tax documents associated with marketplace coverage

Contact Blue Shield for:

• Premium payments
• Member ID cards
• Benefits and eligibility shown by the plan
• Claims and EOBs
• Finding network providers
• Changing a primary-care physician
• Prior authorization
• Reinstatement questions after nonpayment

• Covered California: 1-800-300-1506
• Blue Shield Covered California guidance: Choose the correct organization

Premium Payments and Coverage Termination

Premium-payment problems may involve:

• A payment applied to the wrong account
• A returned or rejected payment
• Automatic-payment failure
• A grace-period notice
• Coverage termination for nonpayment
• Covered California subsidy changes
• An employer payroll-deduction error

For a disputed payment or termination:

1. Save the invoice and payment confirmation.
2. Confirm the coverage month involved.
3. Call the number on the ID card.
4. Ask whether the account is active, delinquent, terminated or eligible for reinstatement.
5. Contact Covered California if eligibility or financial assistance is involved.
6. Contact the employer when payroll deductions or employee enrollment are involved.
7. Request a written explanation and appeal instructions.

Do not assume that making a payment automatically reinstates terminated coverage. Obtain confirmation of the effective date.

Employer-Sponsored Blue Shield Plans

Members covered through work should call the number on their ID card for claims, benefits, providers and authorizations.

The employer’s human-resources or benefits department may need to address:

• Enrollment dates
• Dependent eligibility
• Payroll deductions
• Open-enrollment selections
• COBRA administration
• Employment-status changes
• Incorrect employee records

An employer may sponsor coverage without deciding whether a medical claim or authorization is approved. Determine whether the plan is fully insured or self-funded and identify the organization named in the appeal notice.

Finding an In-Network Doctor or Facility

Network participation can vary by plan, medical group, location and service. A provider who accepts one Blue Shield plan may not accept another.

Before non-emergency care:

1. Search using the exact plan shown on the ID card.
2. Call the provider’s office.
3. Call Blue Shield to confirm network status.
4. Verify the facility, physician, laboratory and other participants separately.
5. Record the date and confirmation information.

• Provider search: Find a Blue Shield doctor or facility

A directory listing is useful but may not guarantee network status for a specific service date. Confirm important care directly.

Provider Leaves the Blue Shield Network

If a doctor, medical group or facility leaves the network, ask about:

• Continuity of care
• Completion of covered services
• Transition to a new provider
• Pregnancy or ongoing treatment protections
• Existing authorizations
• Prescription continuity
• Medical-record transfer

Submit requests promptly and keep documentation from the treating provider explaining the ongoing course of care.

Prescription and Pharmacy Problems

The correct pharmacy contact can depend on the plan and drug benefit. Use the pharmacy number printed on the member ID or prescription card.

Common issues include:

• Drug not on the formulary
• Prior authorization
• Step therapy
• Quantity limits
• Specialty-pharmacy requirements
• Refill-too-soon rejection
• Incorrect copayment
• Mail-order delivery

Ask the pharmacy for the exact rejection message and have the prescriber submit required clinical information. Review the denial notice for appeal rights.

Behavioral-Health and Substance-Use Support

For behavioral-health benefits, eligibility, claims or grievances, call 1-877-263-9952 or use the plan-specific number on the ID card.

For immediate danger or a life-threatening emergency, call 911. People experiencing a mental-health or suicide crisis can call or text 988.

When requesting behavioral-health help, ask about:

• In-network therapists and psychiatrists
• Urgent appointments
• Telehealth
• Prior authorization
• Residential or inpatient care
• Substance-use treatment
• Out-of-network access when no suitable provider is available

Blue Shield Promise can help with benefits, claims, provider access, authorizations, grievances and medical bills related to covered services.

County eligibility offices and California Health Care Options handle certain eligibility and plan-enrollment matters. Do not assume Blue Shield can change income records or county eligibility determinations.

Medi-Cal Ombudsman Help

The California Medi-Cal Managed Care Ombudsman can help members navigate managed-care enrollment, access and unresolved plan problems.

• Medi-Cal Managed Care Ombudsman: 1-888-452-8609
• Hours: Monday-Friday, 8 a.m.-5 p.m. PT, excluding state holidays
• Official information: DHCS Ombudsman assistance

Language, Accessibility and Authorized Representatives

Blue Shield offers language assistance at no additional cost. Call the number on the ID card or 1-866-346-7198.
