Medicare denied G0438. My original claim was billed as follows 99214, dx 250.00 and G0438, dx V70.0. However I did not put a modifier 25 on the claim. The 99214 was paid, but not the G0438. So I corrected the claim and used modifier 25 and it is still getting rejected. I get error code "duplicate claim" for the 99214 (this is correct as it has been paid). However, the G0438 is still denied, saying "This service/procedure that a qualifying service/procedure be received and covered. The qualifying other service/procedure has not been received/adjudicated." Does anyone have any ideas?
