Coordination of benefits: How to submit electronic claims successfully
September 27, 2022

This article is for dentists and oral surgeons caring for our members

To make sure that we process your coordination of benefits electronic submissions correctly, please check whether you are using the most up-to-date version of your practice management software and that it can support line-level data entry. 

Before submitting claims electronically, you must determine the primary payer and submit the claim to that payer first.  When Blue Cross and Blue Shield of Massachusetts is the secondary payer, you must report:

  • the primary insurer’s name and address
  • the insured member’s ID number for that insurer
  • for claims paid by the other insurer*, report the amount paid at the claim’s line level. We recommend contacting your practice management software vendor to ensure each claim line being reported has either the primary insurance paid amount or reject reason. Your claim may be rejected if this data is not supplied.
  • for claims that were denied by the primary insurer, report the reject reason.

*You can learn more on our dedicated coordination of benefits page, including a member fact sheet.
