Secondary to Medicare Claims

Primary remittance advice information must be included when sending secondary claims to BCBSKS.

Secondary claims received more than 30 days prior to the date of the Medicare remittance advice will be rejected in EDI.

Note: In some instances, practice management software may automatically produce a secondary claim upon posting of the primary payment. Providers are encouraged to contact their software vendor or billing service to review the secondary process to prevent these rejections.
