i'm working for FQHC.
We are billing all services 'incident to' physician services to Medicare, but getting RTPd reason codes like 32402, 32404.
what revenue code can be used for lab services to bill Medicare.
You dont use a modifier on the 36415 but the lab has to bill for the actual labs. Medicare will not reimburse you for the labs. Medicare and Medicaid have to be billed by the lab. In an FQHC you bill private pay patients and private insurance only for venipuncture and labs using a modifier 90 on all the labs.
