Ask Dr. Z

Our hospital started doing CardioMems HF system in 2014. We see that there is a new HCPCS code for OP coding as of October 1, 2014: C9741 (RHC with implantation of wireless pressure sensor in the PA including any type of measurement, angio, imaging supervision and interpretation report; includes provision of patient home electronics unit).

Would it be appropriate to code a diagnostic right heart cath when pressures are taken in the RA and RV if it is done for diagnostic purposes since the CardioMems itself includes a RHC? Can you touch on IP vs. OP vs. physicoan coding (CPT and ICD-9 px)? We know what the vendor is suggesting as far as coding, but we are lacking official coding guidance. Also, do you know of any medical necessity ICD-9 diagnosis requirements?
