Hello, We are having some issues with getting our Medicare claims paid, When we bill the claim it gets rejected with “Acknowledgement Rejected for Invalid Information – The claim encounter has invalid information as specified in the Status details and has been rejected. Subscriber contract member number.” The actual medicare number was put in (looking at the card) Any ideas? Also because we only have a “Temporary ID” to bill for Covid only for now, Is there somewhere to look up the Medicare numbers? Thank you in advance!
