Cigna defines a clean claim as one that can be processed and paid without additional information from the provider or the member. That definition sounds simple — but the list of elements required to meet that standard is long, and any one of them can trigger an edit that delays your payment by 30–45 days.
The Core Clean Claim Elements
For professional claims (CMS-1500), Cigna requires the following fields to be complete and accurate:
- Patient and subscriber information — Member ID exactly as it appears on the ID card, date of birth, name matching the plan record
- Rendering and billing provider NPIs — Both Type 1 (individual) and Type 2 (organization) NPIs where applicable
- Dates of service — From and through dates, with through date not preceding the from date
- Place of service code — Must match the actual care setting (11 = office, 21 = inpatient, 22 = outpatient hospital, etc.)
- Procedure codes (CPT/HCPCS) — Valid for the date of service, not deleted codes
- Diagnosis codes (ICD-10-CM) — Specific, current, valid for the DOS, and linked appropriately to procedure codes
- Modifiers — Required where applicable (laterality, professional component, assistant surgeon, etc.) and used correctly
- Units/quantity — Consistent with CPT code description
- Charges — Must be greater than $0
Common Cigna-Specific Edit Triggers
Beyond the CMS-1500 standard, Cigna runs additional edits that catch common billing errors:
Modifier misuse: Modifier 25 (significant, separately identifiable E&M on same day as procedure) is heavily scrutinized. If you append it, the E&M documentation must clearly support a separate, medically necessary visit. Cigna audits modifier 25 usage and will downcode or deny if documentation doesn't support it.
Global surgery period billing: Cigna enforces global surgery periods per CMS guidelines. Billing E&M or related services during a global period without modifier 24 (unrelated E&M) or 79 (unrelated procedure) will trigger an edit.
Diagnosis code specificity: Cigna rejects unspecified codes in many categories where a more specific code exists. If you're using a .9 code, expect an edit request in categories like fractures, laterality conditions, and encounter type.
Electronic vs. Paper Submission Standards
Cigna processes electronic claims (837P/837I) faster than paper and applies the same clean claim edits. EDI loop and segment requirements must be complete — missing data in required loops like Loop 2010AA (billing provider) or Loop 2300 (claim information) will reject at the clearinghouse level before Cigna even receives the claim.
Timely Filing: 90 Days for Most Plans
Cigna's standard timely filing window is 90 days from date of service for most commercial products. Some employer group plans have negotiated different windows — check the specific plan contract or the member's ID card if you're unsure. Cigna MA plans follow the CMS 12-month rule.
What Happens When a Claim Fails the Clean Claim Standard
Cigna is required by most state regulations and the ACA to request additional information within 30 days of receiving a claim if it's not clean. You'll receive a request for information (RFI) or development letter. Respond promptly — the timely filing clock continues to run while you're responding.
Bottom Line
Cigna's clean claim standard is rigorous but predictable. Build a pre-submission scrubbing workflow that checks each element on this list, and you'll catch most edit triggers before they delay payment. The modifier rules and diagnosis specificity requirements are where most teams leave money on the table — focus there first.
