Prepare now for 50+ new codes associated with 998.11. When your anesthesiologist participates in a surgical case because the patient had bleeding (hemorrhage) problems, you typically include 998.11 (Hemorrhage complicating a procedure) as one of your diagnosis codes. That will change once ICD-10 goes into effect, so start thinking now about ways to review the anesthesiologist's documentation " and possibly the surgeon's -- for important details about the hemorrhage location and timing. Here's why: You'll also need to know the location of the bleeding, because the ICD-10 codes designate an anatomical type of procedure that leads to the hemorrhage. For example, you might choose J95.830 (Postprocedural hemorrhage and hematoma of a respiratory system organ or structure following a respiratory system procedure) for hemorrhage associated with a lung procedure or N99.61 (Intraoperative hemorrhage and hematoma of a genitourinary system organ or structure complicating a genitourinary system procedure) for a genitourinary procedure hemorrhage.
