I am sorry , my CPT book has no separate procedure designations any long and I have not had a book in years that does, I remember a notice from way back that stated the separate procedure designation was a thing of the past. However the code in question here 44005 is routinely bundled into every open procedure. I have always found this to be true in the CCI edits. If your book still has a separate procedure designation I am at a loss as to why they are different but it is not the first time I have encountered this with the code books. However even so , the designation of separate procedure does not prohibit the coding of two procedure it just follows the same logic as the CCI edits that you must support a separate site or incision or time of day. I apologise I was unaware of this difference in code books.
