{{cquote|
- ===Type 0===: no bleeding
- ===Type 1===: bleeding that is not actionable and does not cause the patient to seek unscheduled performance of studies, hospitalization, or treatment by a health-care professional; may include episodes leading to self-discontinuation of medical therapy by the patient without consulting a health-care professional.
- ===Type 2===: any overt, actionable sign of hemorrhage (eg, more bleeding than would be expected for a clinical circumstance, including bleeding found by imaging alone) that does not fit the criteria for type 3, 4, or 5 but does meet at least one of the following criteria: (1) requiring nonsurgical, medical intervention by a health-care professional, (2) leading to hospitalization or increased level of care, or (3) prompting evaluation
- ===Type 3===
- ====Type 3a====: Overt bleeding plus hemoglobin drop of 3 to < 5 g/dL* (provided hemoglobin drop is related to bleed)Any transfusion with overt bleeding
- ====Type 3b====: Overt bleeding plus hemoglobin drop more than or equal to 5 g/dL* (provided hemoglobin drop is related to bleed)Cardiac tamponade, Bleeding requiring surgical intervention for control (excludingdental/nasal/skin/hemorrhoid), Bleeding requiring intravenous vasoactive agents
- ====Type 3c====: Intracranial hemorrhage (does not include microbleeds or hemorrhagic transformation, does include intraspinal), Subcategories confirmed by autopsy or imaging or lumbar puncture, Intraocular bleed compromising vision.
- ====Type 4====: CABG-related bleeding, Perioperative intracranial bleeding within 48 h, Reoperation after closure of sternotomy for the purpose of controlling bleeding
Transfusion of more than equal to 5 U whole blood or packed red blood cells within a 48-h period, Chest tube output more than or equal to 2L within a 24-h period
- ===Type 5===: fatal bleeding
- ====Type 5a====: Probable fatal bleeding; no autopsy or imaging confirmation but clinically suspicious
- ====Type 5b====: Definite fatal bleeding; overt bleeding or autopsy or imaging confirmation
