1. If the “primary” insurer denies your claim because the policy has terminated, do not submit an MSP claim.  In this case you would bill as Medicare primary, with occurrence code 18 (beneficiary) or 19 (spouse) indicating the date the “primary” insurance terminated.  In the remarks section, indicate that the policy has terminated.
2. If Medicare is primary, do not use occurrence code 24, or MSP value codes.
3. If Medicare is secondary, do not use occurrence codes 18, 19 or 25.
4. Claims submitted as Medicare secondary require a value code indicating the amount of the primary payment. 
5. If the primary paid denied the claim, bill Medicare as primary with occurrence code 24 with the date of the denial.
6. If your claim has been put in “RTP” status, correct the error and resubmit.
