Antepartum hemorrhage, unspecified, unspecified trimester

This code signifies bleeding from the genital tract during pregnancy where the specific cause of the hemorrhage is not documented or determined. It indicates an uncharacterized bleeding episode occurring at any point during the gestational period before labor.

Apply this code when the medical record clearly states "antepartum hemorrhage" but provides no further details regarding the etiology (e.g., placenta previa, abruption) or the specific trimester in which it occurred. Documentation must explicitly lack information about the cause and trimester.

• Avoid using this code if the cause of the antepartum hemorrhage is known; instead, code to the specific condition (e.g., O44 for placenta previa).
• Do not use if the trimester is documented; instead, select the appropriate trimester-specific unspecified antepartum hemorrhage code (O46.91-O46.93).
• Ensure the documentation explicitly states "unspecified" or provides insufficient detail to assign a more specific code.
