EviCore prior authorization: how the approval process works

EviCore manages prior authorization for more than 60 million members across major commercial and government health plans, but EviCore is not the insurer. It is a specialty benefit manager that health plans delegate clinical review to, which means you submit and appeal through EviCore’s portal even though the coverage rules belong to the health plan.

This guide is written for billers and authorization coordinators who get redirected to EviCore by payers such as Cigna, Aetna, and many Blue Cross Blue Shield and Medicare Advantage plans. A single submission error on EviCore’s portal can pend a case for days, so precision on the first pass matters.

What EviCore is

EviCore (currently EviCore by Evernorth) is a specialty benefit manager contracted by health plans to conduct clinical review on their behalf. Providers often receive a prior authorization requirement from a payer and then get redirected to EviCore, because the payer has delegated that clinical review function to EviCore, not because EviCore is the insurer.

Aetna uses EviCore for radiology, cardiology, and musculoskeletal prior authorization. Cigna and multiple Blue Cross Blue Shield plans, along with many Medicare Advantage plans, also contract with EviCore for specialty benefit management across imaging, oncology, and musculoskeletal services. Because EviCore operates under the contracting payer’s medical policy, denials issued by EviCore carry the same appeal rights as denials issued directly by the insurer, and you do not need to go back to the payer to start an appeal: EviCore handles both the initial review and its first-level appeal through its own provider portal.

One naming note. The current entity is EviCore by Evernorth. Do not submit to or reference legacy brands such as CareCore National or MedSolutions; those entities no longer exist under those names, and using them on a submission only creates confusion.

Which services

EviCore’s clinical review programs cover six specialty areas. Which specific codes require review still depends on the health plan and the plan year, so confirm the requirement for the patient’s plan before scheduling.

• Advanced imaging (MRI, CT, PET scans)
• Cardiology (stress tests, cardiac imaging, interventional procedures)
• Oncology (radiation oncology, systemic therapy)
• Musculoskeletal and spine (physical therapy, spinal procedures, orthopedic surgery)
• Sleep management (diagnostic sleep studies, CPAP and related equipment)
• Lab and genetics (molecular diagnostics, genetic testing panels)

Two operational rules apply regardless of specialty. First, CPT code-level authorization requirements vary by plan year and contract: a code that required EviCore review under a patient’s 2025 plan may be handled differently in 2026, so verify current requirements through the EviCore provider portal before scheduling. Second, performing a service without prior authorization when EviCore review is required produces a denial that is significantly harder to overturn than a clinical denial, because it is an administrative failure with limited appeal pathways, not a clinical disagreement.

For pharmacy-administered oncology drugs, the medical-versus-pharmacy benefit split matters. Some payers route medical-benefit drugs (administered in a clinical setting) through EviCore for prior authorization, while pharmacy-benefit drugs route through the payer’s pharmacy benefit manager. Confirm which benefit applies before submitting to EviCore for oncology cases.

How to submit

EviCore accepts prior authorization requests through three channels, but the portal is the primary one: it is faster to track and generates a real-time case number immediately. Gather the required data before opening the portal.

• The patient’s insurance member ID exactly as printed
• The ordering provider’s NPI
• The rendering facility’s NPI
• The relevant CPT and ICD-10 codes
• Clinical documentation supporting medical necessity

Missing or mismatched NPI information is among the most common reasons EviCore places a case in pend status, adding two to five business days to the review timeline. Submit through the EviCore provider portal: log in through the Provider’s Hub, select the appropriate clinical program, and complete the structured clinical intake form. The portal generates a case number on submission, so record it immediately.

Use phone or fax only when portal access fails. EviCore accepts phone submissions for providers without portal access; fax is available as a fallback but does not provide a real-time case number, which creates tracking delays. For urgent cases where standard review timelines would seriously jeopardize the patient’s health, request an expedited determination at submission. Then track case status through the Provider’s Hub: check for pend notices (which indicate missing documentation or information requests) promptly, because pend notices have response deadlines and missing them resets the review clock. Standard turnaround for non-urgent cases varies by program and payer contract, so confirm the applicable timeline through the portal for each case.

How to appeal a denial

Before filing any appeal, categorize the denial, because EviCore issues three distinct types and each has a different next action.

For a clinical denial, the appeal ladder runs in order, and missed windows close options permanently:

1. Request a peer-to-peer review, the fastest and highest-yield option. The denial letter specifies the deadline, so confirm that window before taking any other action. The peer-to-peer connects the ordering provider directly with an EviCore medical director and can reverse a denial within one business day. Structure the argument around EviCore’s own published clinical criteria rather than submitting generic chart notes.

2. File the first-level reconsideration or appeal through EviCore’s Provider’s Hub. Submit new or additional clinical documentation that directly addresses the specific criterion cited in the denial. Repeating the original submission without addressing the stated gap does not change the outcome.

3. Escalate to the health plan’s upper or external appeal levels. If EviCore upholds the denial, the case moves to the health plan’s higher appeal levels, including external review by an IRO. For plans governed by ERISA, the external review process is federally mandated. For Medicare Advantage plans, the path follows CMS appeals requirements, which differ from commercial timelines. Confirm which framework governs the patient’s plan before filing.

How Silna reduces denials

Most avoidable EviCore denials trace to two preventable causes: incomplete clinical documentation and administrative data errors such as a wrong NPI or a mismatched member ID. Both are detectable before the request leaves the practice. EviCore reviewers evaluate submissions against published clinical guidelines, and the single most common documentation gap on musculoskeletal and imaging requests is prior conservative treatment that is asserted but not documented with its course, duration, and outcome.

Silna Health’s Care Readiness Platform addresses this at the source. Silna’s Predictive Document Intelligence flags documentation gaps and data errors before submission, preventing the most common denial triggers before the case reaches EviCore. By combining automation with built-in payor communication, Silna cuts pre-visit administrative work by 95%, per Silna Health, 2026.

Silna is staffed by insurance administrators with specific ABA therapy experience who understand the difference between medical and behavioral health authorization requirements, a distinction that matters when submitting ABA-related cases through EviCore for plans that cover behavioral health services. For teams managing EviCore-delegated work across imaging, MSK, and oncology lines, Silna coordinates the full workflow so the first submission is the complete submission.
