I know that most insurances do not pay for surgical trays A4550 and that we cannot bill to others such as Medicare. But does anyone know if there are specific guidelines when billing A4550 along with a procedure? For example, for EMR does that actual code need to be specifically documented as "A4550" or can it simply be referred to within the body of the office notes with a simple statement such as "...sterile technique used for procedure"? Thanks.
