How do I appeal a denied claim with Cigna?

Call the number on your Cigna ID card within 180 calendar days of the initial payment or denial notice. If customer service cannot resolve the issue, submit a written Customer Appeal with your member ID, claim number, EOB or denial letter, and supporting records. You can also start through myCigna Forms Center when your plan allows online filing.

What is the deadline to appeal a Cigna denied claim?

Cigna states you should begin the appeal process within 180 calendar days of the date on the initial payment or denial notice. Some state laws and employer plan documents allow longer windows. The deadline printed on your adverse benefit determination or EOB controls your case, so confirm it before you mail your packet.

Where do I send a Cigna appeal letter?

Use the appeals mailing address on your EOB, denial letter, or the Customer Appeal Request form instructions. Cigna uses different addresses for GWH-Cigna and other product types. The form warns that sending non-appeal correspondence to the appeals address can delay processing.

Can I appeal a Cigna denial online through myCigna?

Many Cigna members can access appeal forms through myCigna after signing in. Go to Forms Center or Claims and follow the appeal instructions for your plan type. Keep a copy of anything you upload and note the confirmation number. Some plans still require a mailed Customer Appeal Request form.

How long does Cigna take to decide an appeal?

Cigna states you will receive a written appeal decision within 30 calendar days for pre-service and post-service medical necessity appeals. Post-service administrative appeals may take up to 60 days. Timelines can vary when Cigna requests additional records or when state law sets a different standard.

What documents should I include in a Cigna claim appeal?

Attach a copy of the original claim, EOB, EOP, or adverse decision letter. Include a clear explanation of why you disagree and any records that answer the denial reason. Medical necessity denials usually need a treating provider statement and relevant clinical notes, labs, or imaging.

What if Cigna denies my internal appeal?

After Cigna completes internal review, you may qualify for external review by an independent reviewer when medical judgment is involved and your plan is subject to ACA external review rules. Self-funded ERISA employer plans follow different escalation paths. Read the adverse appeal decision for the exact form, deadline, and address.

How do I appeal a Cigna Express Scripts pharmacy denial?

Pharmacy denials often route through Express Scripts rather than the medical appeals address. Check your pharmacy EOB for the PBM appeal fax or portal. Submit a formulary exception or prior authorization appeal with your prescriber's letter and documentation of failed step therapies when that is the cited reason.

Flowchart showing Cigna denied claim appeal steps from EOB review through myCigna submission to external review

To appeal a Cigna denied claim, call the number on your ID card within 180 calendar days of the initial payment or denial notice, then submit a written Customer Appeal with your EOB, claim number, and records that answer the denial reason. Cigna issues medical necessity decisions within 30 calendar days for many appeals and administrative post-service appeals within 60 days. If internal review upholds the denial, you may request external review when your plan qualifies under ACA rules printed on your adverse decision letter.

What Should You Do First When Cigna Denies Your Claim?

Key Takeaway: A Cigna denial means the plan processed your claim and refused to pay all or part of it. Pull the EOB or adverse benefit determination, note the reason code, and mark the appeal deadline before you call member services or draft a letter.

Cigna posts most decisions on your Explanation of Benefits or Explanation of Payment. If you only received a phone call, ask for the decision in writing with appeal rights. Match each denied line to the remark code, then decide whether you need a corrected claim from your provider or a formal member appeal.

For general denial steps that apply to any carrier, start with our guide on what to do when an insurance claim is denied. For Cigna-specific forms and escalation paths, see the Cigna appeal guide. Coding errors may be fixed when your provider resubmits. Medical necessity and prior authorization denials need a written appeal with clinical records.

How Does the Cigna Internal Appeal Process Work?

Key Takeaway: Cigna uses a three-step member process: call customer service, file a written appeal with supporting documents, and review the written decision before you escalate to external review when eligible.

Call the number on your Cigna ID card within 180 calendar days of the initial payment or denial notice.
Explain why you believe the decision should change and ask how to file a formal appeal.
Submit the Customer Appeal Request form or a letter labeled as a Customer Appeal with your EOB and records.
Save proof of mailing or portal confirmation with the date you filed.
Read the written appeal decision and note any external review rights and deadlines.

Cigna's appeals and grievances member guide notes that state requirements may differ from the standard process. Check your Group Insurance Certificate or Summary Plan Description when the EOB deadline conflicts with Cigna's general instructions.

What Documents Do You Need for a Cigna Claim Appeal?

Key Takeaway: Cigna's Customer Appeal form lists the EOB, claim copy, and supporting documentation as core elements. Medical necessity denials need a provider narrative tied to the exact denial reason.

Member ID, claim number, and date of service from the EOB or denial letter
Customer Appeal Request form or letter clearly labeled as a Customer Appeal
Letter of medical necessity or office notes addressing the cited denial reason
Prior authorization numbers, referral records, or imaging and lab results when relevant
Plan policy excerpts or clinical guidelines only when they support your specific argument

How Do Cigna Appeal Deadlines and Timelines Work?

Key Takeaway: You generally have 180 calendar days from the initial denial notice to start a Cigna appeal. Response clocks differ for medical necessity and administrative denials. Mark both dates on your calendar.

Appeal type	File by	Cigna decision target
Pre-service medical necessity	180 days from initial notice (confirm on EOB)	Written decision within 30 calendar days
Post-service medical necessity	180 days from initial notice (confirm on EOB)	Written decision within 30 calendar days
Post-service administrative	180 days from initial notice (confirm on EOB)	Written decision within 60 calendar days

ACA marketplace plans and some fully insured products may offer external review after internal denial under Healthcare.gov external appeals guidance. Self-funded ERISA employer plans follow Department of Labor claims procedures and may not offer state external review.

Can You File a Cigna Appeal Through myCigna?

Key Takeaway: Many members can access appeal forms in myCigna Forms Center or Claims. Online filing does not remove the need for a complete clinical packet when the denial cites medical necessity or prior authorization.

Sign in to myCigna and look for Claims, Forms Center, or appeal instructions tied to your product. Upload the same records you would mail with the Cigna Customer Appeal Request form. Save confirmation numbers and dates. If your plan requires mail, send the form to the appeals address on your EOB rather than a general claims P.O. box.

Weak vs. Strong Cigna Appeal Language

Key Takeaway: Cigna reviewers need claim identifiers and facts tied to the denial code. Emotional language without clinical support rarely changes a medical necessity determination.

❌ Weak Request	✓ Strong Request
“I disagree with Cigna's decision. Please pay the claim.”	“Customer Appeal for claim #[number] denied as not medically necessary on [date]. Attached physician letter and MRI report dated [date] address Cigna criterion for [service].”
“My doctor ordered this test.”	“Dr. [name] documents failed conservative treatment for [diagnosis] from [start] to [end]. The service meets plan criteria when [finding] is present, which applies per attached notes.”
“I called Cigna and nobody helped.”	“I filed this Customer Appeal on [date] via myCigna confirmation #[number]. This packet adds the prior authorization reference #[number] requested on [date].”

What Happens After You File a Cigna Appeal?

Key Takeaway: Cigna must issue a written appeal decision within the timeframe that applies to your denial type. Save your confirmation number and follow up if you do not receive a letter. An adverse outcome should explain external review or other next steps.

If Cigna upholds the denial, read the letter for independent external review rights when medical judgment is involved. Cigna states that in most cases you must complete internal review before arbitration or legal action. For prior authorization denials specifically, see our guide on how to appeal a prior authorization denial.
