Information About Filing Secondary Claims

All HNS providers are required to submit secondary claims through HNS if the secondary coverage is provided by an HNS Contracted Payor.

At this time, secondary claims must be sent to HNS via the CMS 1500 claim and cannot be submitted via HNSConnect^®.  All secondary claims and claims with attachments must be mailed to HNS.

Please ignore the address on the member's ID card as well as any instructions you may receive when verifying benefits regarding where to submit claims.  HNS instructions supersede all other instructions regarding where to submit claims.

Timely Filing

Secondary claims must be submitted to HNS within 15 days of receipt of the primary EOB.

NOTE:  You must have the original EOB from the primary carrier before you can file the secondary claim to HNS.  When filing a secondary claim to HNS, please follow these guidelines:  

1. Generate a new CMS 1500 claim form for the same date of service including all services that were shown on the original primary claim.
   
   
2. Complete boxes 9, 9a, 9d, and 11d.
   
   Note: Boxes 9, 9a, 9d, and 11d must be completed on BOTH the primary and secondary claim form.
   
   
3. For NC Providers, if the claim is a secondary claim and Medicare is primary, Box 14 (Date of Current Illness) must be completed.
   
   
4. Staple the primary EOB to the claim form and mail to HNS.

If you are a North Carolina provider filing BCBS as secondary coverage to Medicare, you must generate a new CMS 1500 claim form, attach the Medicare EOB, and mail it to HNS.  (Medicare crossover claims to BCBSNC will NOT result in payment of your claim.  The claim must be filed through HNS.)

For more details concerning preparing secondary claims, please carefully review the requirements for secondary claims in the HNSConnect User Manual. This helpful manual provides clear guidance on how to prepare and submit secondary claims (as well as other important and helpful information). The manual is posted under HNS Forms.
