Is there something I'm missing? When I bill an office visit 99213 and a lab 81000 Medi-Cal will only pay the office visit and deny the lab as only one exam covered on the same day. If I bill an EKG 93000 they will pay the EKG and not the office visit with the same denial reason. Should I just bill the office visit and not bill the lab or prepare to write off the lab charge or whatever charge they won't pay? Thank you in advance.
