I am new to this so please excuse any errors I might do. I am having issues with getting Medicare to pay for 67820. I billed out separately for a E1 and E3. Denial was CO-151 Payment adjusted because this payer deems the information submitted does not support this many/ frequency of services. When it was billed out it was billed out separately. Line one was 67820 with modifier of E1 and line two was 67820 modifier of E3. Thanks for your help.
