Final answer:
When the same payer issues primary and secondary policies, a single CMS-1500 claim should be submitted.
Step-by-step explanation:
When the same payer issues the primary and secondary or supplemental policies, a single CMS-1500 claim form should be submitted.
This is true because submitting separate claims for primary and secondary policies can lead to confusion and potential billing errors. By submitting a single claim, the payer receives all the necessary information in one submission, streamlining the process.
For example, if a patient has both Medicare (primary) and a private insurance (secondary), the same payer would issue both policies. In this case, a single CMS-1500 claim should be submitted to the payer.
