O45 Premature separation of placenta [abruptio placentae]
ICD-10-CM category O45 sits in Chapter 15 (Pregnancy, childbirth and the puerperium, O00-O9A). It contains 24 billable codes for FY2027, effective October 1, 2026 to September 30, 2027. Always code to the most specific code available: a code with more characters that describes the diagnosis more precisely takes priority over a shorter one.
