Wiki Incomplete colonoscopy in asc

[vmounce]

For incomplete colonoscopy due to poor prep, would I use modifier 74? The doctor is going to redo colonoscopy at a later time. I believe this is correct but wanted to make sure. I appreciate the info.

Yes, you would use modifier 74 and diagnosis code V64.1 or V64.3 as secondary dx.

Thanks for the response. What would I use as 1st diagnosis? I have been using V64.1 as primary and the symtoms as secondary. I didn't realize V64.1 was a 2nd diagnosis. But, we have been getting paid.
