Summary
Health Net has clarified requirements for three common reject codes to help providers avoid claim rejections. The policy provides specific instructions for handling corrected claims (code 76), new claims (code AK), and claims requiring other insurance information (code C6).
Action Required
Immediately: Billing team must update claim submission procedures: 1) For corrected claims, always include original claim number in UB-04 box 64 or CMS-1500 box 22 with frequency/resubmission codes 7 or 8 only. 2) For new claims, leave UB-04 box 64 and CMS-1500 box 22 completely blank. 3) For members with other insurance, complete CMS-1500 fields 9, 9a, 9d, mark 'yes' in 11d, and attach other insurer's EOB. Train staff on these requirements to prevent claim rejections and resubmission delays.
