Does anyone know what ICD-10 code can be used with the new End of Life Care CPT codes 99497 and 99498? I believe the HCPCS code might be S0257. For non-medicare patients Z02.89 looked like it might be suitable, but I'm not sure. Does anyone have advice? I have also received mixed messages on whether or not the half rule applies to 99497. Does a physician need to spend at least 16 minutes with the patient planning or does anytime with the first 30 minutes apply?
