Answer: The short answer is that you should appendmodifier 57 (Decision for surgery) to the non-consult inpatient E/M code that the documentation supports.

Suppose the ob-gyn performed a 2009 level-three inpatient consult in which the ob-gyn determined the patient required an exploratory laparotomy later that sameday due to severe abdominal distention and pain as well as some uterine bleeding. Adding the modifier to the E/M code will help show payers why you’re reporting an EM in addition to the major surgery performed later that day, 49000 (Exploratory laparotomy, exploratory celiotomy with or without biopsy[s] [separate procedure]).

For 2010, the exact E&M code you choose will depend on the circumstances specific to the visit, such as whether the visit is the first or second ob-gyn visit during the admission. But as an example, suppose you’re coding the ob-gyn’s first visit to an inpatient. Your documentation may support 99221 (Initial hospital care, per day, for the evaluation and management of a patient, which requires these 3 key components: a detailed or comprehensive history; a detailed or comprehensive examination; and medical decision making that is straightforward or of low complexity …), which has requirements similar to 99253 (Inpatient consultation for a new or established patient, which requires these 3 key components: a detailed history; a detailed examination; and medical decision making of low complexity).

You should append modifier 57 to the E/M code. If, instead, the ob-gyn is the principal physician — the one overseeing the patient’s care and the one who is admitting the patient — be sure to append modifier AI (Principal physician of record), as well. This would be the case if the ob-gyn admitted the patient for observation for the abdominal pain and bleeding but later made the decision to take her to surgery that same day.
