EviCore does not publish a single universal appeal form. The EviCore appeal is a written submission you build from the denial letter you received, and that letter is where every specific — case number, cited clinical guideline, deadline, fax number or mailing address — actually lives. Appeal rights, timelines, and destinations vary by health plan and by state even though EviCore handled the review, so the letter, not a generic template, is the document that tells you what to file and where.
Start With the Denial Letter
Every EviCore denial produces a determination letter sent to both the patient and the ordering provider. It names the specific clinical guideline the reviewer applied, explains why the request did not meet that guideline, and lists your post-decision options: reconsideration, a peer-to-peer discussion, and formal appeal. The appeal deadline and the submission method printed on your letter are set by your health plan and can differ from another patient’s letter even when EviCore is the reviewer for both.
Providers can also see post-decision options by logging into the EviCore portal and opening the Authorization Lookup tab, which lists the choices configured for that health plan.1EviCore. General Frequently Asked Questions Keep the letter within reach while you prepare the appeal; you will need the case number and the exact wording of the cited criteria.
Consider a Peer-to-Peer Discussion First
Before drafting a written appeal, the ordering physician can ask for a peer-to-peer call with the EviCore reviewer who issued the denial. It is a phone conversation, and it sometimes resolves the issue without a written appeal. EviCore offers two ways to schedule it:
- Online: the provider logs into the EviCore portal and picks a time using the scheduling tool. Appointments can be rescheduled or cancelled from the same dashboard.
- Request form: the provider completes a peer-to-peer request form on the EviCore website, which routes to the Physician Support Unit. The form asks for the program, health plan, case number, the member’s name and date of birth, and whether the procedure has already been performed.
If the reviewer reverses the decision on the call, the service can be authorized without a written appeal. If not, the written appeal option remains open.2EviCore. Request a Peer-to-Peer Discussion
What to Put in the Written Appeal
Only written appeals start the formal appeal clock; oral requests do not.3eviCore healthcare. Musculoskeletal Appeals Frequently Asked Questions A written appeal is a cover letter with clinical attachments organized to address the reason for the denial. Assemble the following:
- Patient full name, date of birth, and insurance member ID.
- EviCore case number from the denial letter — this is how the appeals team locates the original file.
- Ordering provider details: National Provider Identifier (NPI), Tax Identification Number (TIN), and phone, fax, and email contact information.
- Clinical records: physician progress notes, relevant lab results, imaging reports, the working diagnosis, patient history including prior treatments, and the requested CPT or HCPCS codes.
What counts as “clinical information” shifts by service line — radiology appeals rely on imaging reports and diagnostic codes; musculoskeletal appeals rely on treatment history and functional assessments.1EviCore. General Frequently Asked Questions
Write the Rationale Against the Cited Guideline
The reviewer is comparing the patient’s situation to a published clinical guideline. The cover narrative should walk the guideline’s criteria one at a time and show how the patient satisfies each one. Cite the ICD-10 diagnostic codes that match the covered indications, reference the CPT code for the requested procedure, and explain the complicating factors — prior surgeries, failed therapies, worsening symptoms — that make the service necessary for this patient.
If anything new has developed since the initial request, include it: a specialist consultation, updated labs, a change in the patient’s condition. Federal regulations require the appeal reviewer to consider all submitted evidence, including material that was not part of the initial determination.4Office of the Law Revision Counsel. 29 CFR 2560.503-1 – Claims Procedure New evidence is the strongest single lever you have on appeal.
How and Where to Submit
Use the submission instructions on your denial letter. Depending on the plan, the letter will point you to one or more of these:
- Fax. The fastest paper-based method; the fax confirmation page is your proof of delivery. Use the number printed on your letter.
- Mail. Send to the appeals address on the letter. Certified mail with return receipt gives you a documented mailing date.
- Online portal. Some plans allow the provider to upload the appeal and clinical attachments through the EviCore portal by opening the original case and selecting the appeal option. Complete the upload through the confirmation screen and save the transaction ID.
EviCore accepts initial appeals up to 180 calendar days after the original denial, though state mandates can shorten or lengthen that window.3eviCore healthcare. Musculoskeletal Appeals Frequently Asked Questions File early. Waiting to the deadline leaves no room to fix a missing document or resend if delivery fails.
How Long the Decision Takes
For pre-service claims — requests for care that has not yet been provided — federal regulations require the plan to decide the appeal within 30 days. Plans that use two internal levels must finish each level within 15 days.5U.S. Department of Labor. Filing a Claim for Your Health Benefits Some plans allow up to 60 calendar days from the appeal request, and state rules can adjust these further.3eviCore healthcare. Musculoskeletal Appeals Frequently Asked Questions
When a patient’s health is in immediate jeopardy, urgent appeals are handled within 72 hours.6EviCore. Ethics and Compliance An expedited request should come from the treating physician and clearly explain why the standard timeline would seriously harm the patient. The decision letter goes to the patient and the provider, and many plans also post it in the member’s online portal. It states whether the denial was upheld or overturned; if upheld, it lays out your remaining options, including external review.
Ask for the Guidelines and Case File
If the plan is an employer-sponsored health plan governed by ERISA, you have a statutory right to see what the reviewer relied on. Under 29 U.S.C. § 1133, the plan must give written notice of a denial setting out the specific reasons, in language designed to be understood by the participant.7Office of the Law Revision Counsel. 29 USC 1133 – Claims Procedure In practice, you can request copies of the clinical guidelines, internal policies, and any medical opinions the denial rested on. If the plan administrator fails to produce requested documents, courts can impose penalties of up to $110 per day for each day of the delay.
Getting these materials shows you the exact standard your appeal has to beat. If the guideline requires documentation of two failed conservative treatments before an MRI is approved, and the chart shows three, that is a clear win on appeal or external review.
External Review After an Internal Denial
If the internal appeal upholds the denial, most plans must offer an independent external review under the Affordable Care Act, conducted by a reviewer with no connection to EviCore or the insurer.8Centers for Medicare & Medicaid Services. External Appeals The insurer must accept the external reviewer’s decision.
You have four months from the date you receive the final internal denial to file a written request for external review. Standard external reviews are decided within 45 days of the request. Expedited external reviews for urgent medical situations are decided within 72 hours or sooner, depending on the circumstances.9HealthCare.gov. External Review
Depending on your state, external review is run either through the state insurance department or through the federal process administered by HHS using accredited Independent Review Organizations. Your final internal denial letter will identify which process applies and where to file.8Centers for Medicare & Medicaid Services. External Appeals
If the Plan Misses Its Own Deadline
When the insurer or EviCore fails to decide within the required timeframe, ERISA regulations treat that as a failure to follow reasonable claims procedures and trigger “deemed exhaustion.” You are then treated as having completed the internal appeal process even though no decision was ever issued, and you can file suit under ERISA Section 502(a) or move directly to external review.10eCFR. 29 CFR 2560.503-1 – Claims Procedure
If you are past the deadline with no response, send a written follow-up noting the missed deadline and stating that you consider administrative remedies exhausted. Keep a copy. That letter can matter later if the dispute moves to an external reviewer or to court.
