Timely Filing Change

Effective January 1, 2015, to be considered for reimbursement, most Wellmark claims must be received within 180 days from the date of service or the discharge date. For dates of service prior to January 1, 2015, the claims must be received within 365 days from the date of service or the discharge date. The 180 day timely filing guideline will also apply to COB claims. When Wellmark is the secondary payer, claims must be filed within 180 days from the issue date of the primary payer’s Explanation of Benefits (EOB). If the primary payer does not issue an EOB, we will use the date on the provider’s remittance advice.
