Ask Dr. Z

Pt. was seen at another hospital A 2 weeks prior were a Left Heart Cath w/ coronary angiography was performed- by Cardiologist- Due to the findings the patient was transferred to hospital B for CABG evaluation as he wasn't deemed a surgical candidate- Cath report available in shared medical record- He has complex coronary disease including calcified LM/RCA- Interventional Cardiology is consulted for intervention of RCA- IC did the RHC w/coronary angio before making the decision to do the intervention-Findings were the vessel is diffusely calcified with 80% stenosis proximal/mid RCA- Upon completion the IC made the decision to intervene on both these areas- It is being stated that the only code that should be billed is the RHC w/o coronary angio since the LHC w/ coronary angio was done 2 weeks prior at outside hospital- I know that coronary angio can not be repeated unless medical necessity is met- Can you provide detailed feedback in this scenario-
