Our clinic is owned by the hosp. I had an ob present to the ED on 1/13 and ended up being admitted to observation. I coded 646.63/590.800/41.4/288.60 with 99217 for the discharged on 1/14. The billing department sent me this note.

TO CODER TO RVW - this visit seems to coincide with Maternity care- please rvw to see if their is a specific modifer that we need to bill with -

Is there a modifer I should use?
