BCBS Prior Authorization Requests Processing Times
Standard Processing Timeframes
BCBS follows industry-standard timelines for prior authorization processing that align with Medicare and regulatory requirements. For routine, non-urgent cases, when you request prior authorization, BCBS processes approvals within up to 15 calendar days from the date they receive your complete request. This timeline applies across most BCBS plans nationwide, though each Blue Cross Blue Shield company operates as an independent company with potential state-specific variations.
Expedited Review for Urgent Situations
When medical situations require immediate attention, BCBS offers expedited review within up to three days (72 hours). To qualify for urgent requests, healthcare providers must request prior authorization and submit medical documentation that demonstrates delays would seriously jeopardize the patient’s life, health, or ability to regain maximum function. Providers must clearly indicate the urgent nature, reference applicable medical policies, and provide supporting medical records.
Emergency Services Exemption
Emergency medical services typically don’t require prior authorization, but it’s important to understand which follow-up healthcare services may still need prior authorization after emergency care. Care that qualifies as emergency stabilization is exempt from prior approval requirements under federal laws and most state mandates. This ensures patients receive immediate, life-saving treatment without administrative delays.
To ensure seamless care, providers should verify the member Qualifications and benefits and use available resources to determine if follow-up services require prior authorization. Prompt submission of complete clinical documentation supports timely review and helps avoid unnecessary delays in delivering critical healthcare.
When Processing Takes Longer
Processing may extend beyond the standard 15-day period when BCBS requires additional medical documentation from your provider, if submitted paperwork is incomplete, or if the service falls under high-complexity categories requiring specialist review. BCBS must notify both the provider and patient if additional information is needed, potentially extending processing by up to 14 additional days under certain circumstances.
Factors That Affect Processing Speed
Documentation Completeness
The most significant factor affecting how long prior authorization takes is the completeness of your initial submission. Incomplete medical documentation, missing procedure codes, or lack of medical necessity rationale cause the majority of processing delays. Providers who submit comprehensive medical documentation, test results, prior treatments attempted, and accurate diagnosis codes experience faster approval times.
Type of Medical Service
Different medical services require varying levels of prior authorization review complexity:
Advanced imaging (MRI, CT scans) often require prior authorization and need detailed justification
Behavioral health services may require prior authorization and specialized clinical review
Generic drugs typically process faster than specialty medications. This is because specialty medications often require prior authorization and involve a more detailed clinical review process.
Certain services like experimental treatments require prior authorization and extensive evaluation
In network providers may have streamlined approval processes
Plan Type and Coverage
Your specific Blue Shield or Blue Cross plan type influences processing speed. Medicare Advantage plans may route prior authorization requests through third-party vendors like Carelon Medical Benefits Management or EviCore, while commercial plans might process directly through BCBS. Each plan, operated by an independent company, has specific prior authorization process and covered benefits that affect review timelines. For example, ge neric drugs often have simplified prior authorization processes, leading to faster approvals compared to specialty medications.
Provider Experience and Compliance
Health care providers familiar with BCBS requirements and medical policies experience higher first-time approval rates and faster processing. Health care practices that routinely verify member eligibility, use correct procedure codes, and submit proper documentation see significantly reduced delays.
Consistent adherence to the prior authorization method and timely submission of all required forms and medical records further streamline approvals. This proactive approach helps providers avoid denials, ensures appropriate payment, and supports better patient outcomes.
Electronic vs Manual Processing Times
Benefits of Electronic Submission

BCBS has committed to achieving near real-time approval for 80% of electronic submissions by 2027. Automated decision systems currently flag routine medical policies and clinical policy criteria for immediate electronic approval, eliminating manual review delay requests that meet s.
Manual Processing Limitations
Paper or fax submissions typically require the full 15-day processing period. Manual requests are slower due to data entry requirements, greater administrative review needs, and higher risk of lost or illegible paperwork. Health care providers should use electronic submission whenever possible to minimize delays.
Electronic platforms enable faster processing by reducing manual errors and expediting the virtual prior authorization support process. Utilizing these tools helps ensure that requests are complete, improving the likelihood of timely approval and better patient care.

How to Expedite Your Prior Authorization
Requesting Urgent Review
To request prior authorization for urgent medical situations, your health care provider must clearly state that the request is urgent and describe the clinical scenario justifying expedited review. The documentation should explain why standard processing timelines would compromise patient care.
Timely and complete submission of clinical documentation helps ensure that urgent requests are prioritized for faster review. Providers should include procedure scripts, health care records, and other relevant details to support the urgency of the treatment and avoid unnecessary delays in the prior authorization methods.
Working with Your Health Care Provider
Collaborate proactively with your doctor to ensure complete prior authorization submissions. This includes:
Gathering all relevant medical records and lab results
Documenting previous treatments attempted
Providing comprehensive clinical justification
Verifying member eligibility and benefits before submission
Using BCBS Online Tools
Before submitting prior authorization requests, be sure to request prior authorization through BCBS online resources to verify if it is required for specific CPT codes. Many BCBS companies offer provider portals where you can check prior authorization requirements, submission guidelines, and track the status of your requests in real time.
Ensuring Clinical Criteria Compliance
Review BCBS medical policies and clinical criteria for your specific service before submission. Understanding coverage requirements upfront helps providers submit requests that meet medical necessity standards, reducing the likelihood of denials or requests for additional information.
Staying informed about evolving health care regulations and plan-specific prior authorization requirements enables providers to streamline the approval process. Efficient navigation of the prior authorization process not only reduces administrative burden but also helps ensure timely access to health care services for members.
What Happens During the Review Process
Initial Administrative Review
BCBS staff first confirm member eligibility, plan coverage, and receipt of all required information including patient details, provider information, procedure codes, and clinical notes. This administrative review ensures the request is complete before clinical evaluation begins.
Clinical Evaluation Process
Licensed clinicians—including registered nurses, pharmacists, or physicians—conduct prior authorization clinical reviews using evidence-based guidelines such as InterQual or MCG criteria, along with BCBS medical policies. This clinical review determines whether the requested service meets established standards for coverage.
Coverage Verification and Decision
Reviewers confirm that requested procedures or medications are covered benefits under the member’s specific plan. After completing clinical and prior authorization coverage reviews, BCBS communicates decisions to both providers and patients, including authorization numbers for approvals or detailed rationale for denials.
Timeline Communication
BCBS provides status updates throughout the prior authorization review process. Approval letters specify authorization numbers, coverage limits, and validity periods. Denial notifications include clinical rationale and information about appeal rights, ensuring transparency in the decision-making process.
Common Delays and How to Avoid Them
Incomplete Medical Documentation
The primary cause of prior authorization delays is incomplete medical documentation. Missing lab results, inadequate clinical notes, or insufficient medical records extends processing times significantly. Always submit comprehensive medical records with your initial prior authorization request.
Incorrect Coding and Service Descriptions
Using outdated procedure codes, incorrect diagnosis codes, or inaccurate service descriptions can delay your prior authorization by triggering requests for clarification. Ensure all coding is current and accurately reflects the intended treatment or service to prevent prior authorization delays.
Eligibility and Benefit Verification Issues
Failing to verify member eligibility and specific plan benefits before submission causes processing delays. Always confirm coverage details and prior authorization requirements for your specific Blue Cross or Blue Shield plan before submitting requests.
Using Incorrect Submission Channels
Submitting requests through non-approved channels, using outdated forms, or missing required provider signatures delays processing. Always use current BCBS-approved submission methods and ensure all required signatures and information are included.
Prevention Strategies
To minimize delays:
Verify member’s eligibility and benefits before treatment
Use electronic platforms to request prior authorization and submit documentation when available
Submit complete clinical documentation upfront, including procedure and diagnosis codes
Double-check all procedure and diagnosis codes for accuracy
