Cigna Billing Overview for Healthcare Providers
Cigna Healthcare, now part of The Cigna Group (which also owns Express Scripts), serves approximately 18 million medical members in the United States. The merger with Express Scripts has created tighter integration between medical and pharmacy benefits, which affects billing workflows for practices that administer specialty medications or provide infusion services. Understanding how Cigna coordinates these benefits prevents duplicate billing denials and ensures proper reimbursement routing.
Cigna offers several plan types including Open Access Plus (OAP), PPO, HMO, LocalPlus, and high-deductible health plans. Each product has different network requirements, referral rules, and cost-sharing structures. The OAP plans are the most common and allow out-of-network access with higher cost sharing. HMO plans require in-network care and often mandate primary care referrals for specialist visits.
Timely Filing Requirements
Cigna’s standard timely filing deadline for in-network providers is 90 days from the date of service on commercial plans. Out-of-network providers generally have 180 days. These deadlines are specified in your provider contract, and some contracts may include longer windows depending on when they were negotiated. Always check your specific contract language if you are approaching a filing deadline.
For secondary claims where Cigna is the secondary payer, file within 90 days of the primary payer’s payment date. Attach the primary payer EOB to the claim. Cigna’s system will crosswalk the primary payment and apply the secondary benefit accordingly. Missing the primary EOB is one of the most common reasons for COB-related denials on secondary Cigna claims.
Corrected claims must be submitted within 90 days of the original remittance date. Mark corrected claims with frequency code 7 and reference the original claim number. Cigna’s system links the corrected claim to the original and adjusts payment accordingly. Do not submit a new claim without the corrected claim indicator, as this triggers a duplicate denial.
Electronic Submission and Payer IDs
Cigna accepts electronic claims through its provider portal (cignaforhcp.cigna.com), Availity, and all major clearinghouses. The primary payer ID for Cigna commercial claims is 62308. This ID routes to Cigna’s main claims processing system and works for most plan types. Some specialty products like Cigna HealthSpring (Medicare Advantage) and Cigna behavioral health use different payer IDs that vary by state.
Professional claims use the 837P format and facility claims use 837I, following ANSI X12 standards. Cigna processes clean electronic claims within 15 to 20 business days. The company defines a clean claim as one with all required data elements, a valid member ID, correct NPI and tax ID, valid diagnosis and procedure codes, and no pending coordination of benefits questions.
Cigna has invested in automated claims adjudication, and approximately 85% of clean claims are processed without human intervention. Claims that trigger clinical edits, high-dollar thresholds, or outlier patterns are routed to manual review, which adds 15 to 30 days. Keeping your coding clean and consistent reduces the chance of triggering these manual review flags.
Prior Authorization Process
Cigna maintains a prior authorization list that is updated at least twice per year. The list is available on the Cigna provider website under “Precertification.” General categories requiring prior auth include elective inpatient admissions, select outpatient surgeries, advanced imaging beyond basic X-ray, specialty pharmaceuticals, durable medical equipment, home health services, and certain behavioral health treatments.
Submit prior authorization requests through the Cigna provider portal for the fastest turnaround. Standard requests are processed within 15 calendar days. Urgent requests tied to imminent treatment receive a decision within 72 hours. Emergency retrospective authorization requests must be submitted within 2 business days of the emergency service. Include clinical notes, test results, and the proposed treatment plan with every authorization request.
When prior auth is denied, request a peer-to-peer review within 10 business days. During the peer-to-peer, the treating physician speaks directly with a Cigna medical director about the clinical rationale. These conversations overturn roughly 25% of initial prior auth denials. If the peer-to-peer does not result in approval, proceed to the formal appeal process.
Denial Patterns and Prevention
Cigna’s top denial reasons mirror industry patterns but with some payer-specific nuances. Prior authorization failures lead at approximately 24% of total denials. Coding and billing errors follow at 21%, with eligibility or COB issues at 16%. Timely filing denials account for 10%, and medical necessity disputes for about 11%. The remaining 18% covers duplicate claims, bundling edits, and referral issues.
Cigna uses ClaimsXten (from Change Healthcare) as its primary claims editing engine. ClaimsXten applies NCCI edits plus Cigna-specific proprietary rules. Common triggers include modifier 25 paired with minor procedures, unbundling of global surgical packages, multiple therapy modalities in a single session, and evaluation codes billed on the same day as surgical procedures without appropriate modifiers.
Referral-related denials (CO-236) are particularly common on Cigna HMO plans. The referring provider must submit the referral before the specialist visit for it to count. Retroactive referrals are accepted in some cases but require the PCP to submit within 5 business days of the service date. Build referral verification into your patient scheduling workflow to prevent these denials.
Appeal Procedures and Deadlines
Cigna’s appeal process includes two levels of internal review. First-level appeals must be filed within 180 days of the adverse benefit determination. Submit through the Cigna provider portal, Availity, or by mail. The appeal must include the claim number, member information, a clear statement of why the denial should be overturned, and all supporting documentation.
Post-service appeal decisions are issued within 30 calendar days. Pre-service appeals are decided within 15 days, and urgent appeals within 72 hours. If the first-level appeal is denied, you have 60 days to file a second-level appeal with a different reviewer. Cigna’s second-level appeal success rate is approximately 15% to 20%, so make sure your strongest evidence is included in the first-level submission.
After exhausting internal appeals, external review is available through the state’s independent review organization. External reviews are binding on Cigna and typically take 30 to 45 days. For contractual disputes (payment rate disagreements rather than clinical denials), use the provider dispute resolution process outlined in your contract instead of the clinical appeal pathway.
