Coding Endoscopy px when done on ER pt

Current process to follow:
Some of the facilities have ER patients who are having endoscopy procedures performed in the endoscopy suite or in the ER. We also have some ER patients who go to the operating room for procedures and then are discharged as an ER patient.
* An ER patient who had a proctoscopy performed in the Emergency room
* An ER patient who went to the endoscopy suite and had an endo procedure performed and discharged as ER patient type
* An ER patient who went to the operating room for a procedure and discharged as ER patient type

We went through what would be charged through the charge master and what the ER coders would be responsible for coding and reporting using Power Abstract and came up with the following:
* ER patient type with operating room charges: ER coder will code both ER procedures and operating room procedures and enter in PA

* ER patient type with Endoscopy procedures: ER coder will code endoscopy procedures performed either in ER (proctoscopy) or the endoscopy suite
