I'm new to billing and have been mostly able to figure things out with my own research, but I cannot get these codes paid by Medicare (Palmetto) - 11055 or 11056. I know they need DLS and PCP name/NPI but can someone tell me EXACTLY how you enter that in Box 19 because I haven't been able to get the correct format yet. Also, do I need to add the PCP as referring provider, or is it sufficient to put the name and NPI in Box 19? Many thanks in advance for help with this.
