I am submitting a claim to Medicare Part B KSMCR Kansas. Says "NPI 1649550096 should be enrolled before you can start submitting claims for payer id: KSMCR. You can learn how to submit your enrollment at https://support.simplepractice.com/hc/en-us/articles/207925273-Submitting-enrollments-for-claim-filing-and-payment-reports"
I have checked with Medicare and Eligible who both say we are registered. What is the issue? How do I fix this?
