Can someone explain to me the difference between these two documents? We always use an ABN and apply the appropriate modifier for non-covered etc. I googled the NEMB and it says it is for a SNF. However it does state that it is to be used when you are making the patient aware that the service is automatically not covered. I was under the assumption (we all know where that leads) that if we had an ABN on file, signed, and the patient is aware that it is noncovered you would bill the code with either the GA or GZ. From what I gather there is no modifier for this NEMB. I, personally, had not heard of it until today. I would think the ABN signed would take it’s place. If someone can provide some insight, I would appreciate it.
