Can anyone help me with billing NP/PA? I know Medicare's Incident To billing guidelines. What about other insurance(BCBS VA, Cigna, Aetna, Tricare, Optima)? Do we have to bill under the NP/PA's NPI or under the supervising MD(if they are on site)? Does the MD have to see the pt for the 1st visit and then the NP/PA can see them for any other visit? Thank you for your help!
