Wyoming Wyo. Stat. §26-40-108 requires insurers to pay or deny clean claims within 45 days of receipt. Late payments accrue interest at 10% per annum, and billers can file complaints with the Wyoming Department of Insurance to recover unpaid claims and interest.
Wyo. Stat. §26-40-108 Prompt Pay Requirements
Wyoming's prompt pay statute applies to all health insurance claims submitted to state-regulated carriers. A clean claim is one that contains all information required for adjudication without need for additional documentation. Payers must pay or deny clean claims within 45 days of receipt; partial payments or requests for additional information restart the clock only for the portion of the claim still in dispute.
What Counts as a Clean Claim in Wyoming
A clean claim includes complete patient demographics, a valid NPI for the rendering and billing providers, correct CPT/HCPCS codes with required modifiers, ICD-10 diagnosis codes that support medical necessity, date of service, place of service, and prior authorization numbers when applicable. Claims missing any of these elements are not clean and do not trigger the prompt pay deadline.
Interest Penalties on Late Payments
When a payer misses the 45-day deadline, Wyoming law requires interest at 10% per annum on the unpaid balance. Interest accrues from day 46 until the payment posts. Billing teams should calculate interest on every late payment and include it on the follow-up demand so the payer pays both the claim and the statutory penalty.
Electronic vs. Paper Submission Timing
Electronic claims are considered received when the payer's clearinghouse issues a 277CA acknowledgment. Paper claims are considered received on the date the payer's mailroom stamps the envelope. Track both dates to start the 45-day clock accurately and to establish proof of receipt for prompt pay disputes.
How to File a Prompt Pay Complaint in Wyoming
- Note whether the claim was electronic or paper and calculate the 45-day deadline from receipt.
- Document the clean claim submission date with clearinghouse records or mailroom stamps.
- Calculate interest at 10% per annum from day 46 through the payment date.
- File a WYDOI complaint with claim records, payer correspondence, and the interest calculation.
