Antepartum hemorrhage w oth coag defect, unsp trimester

This code signifies bleeding from the genital tract during pregnancy, prior to labor, when the underlying cause is an unspecified coagulation defect. This hemorrhage is not specified as occurring in the first, second, or third trimester.

Apply this code when documentation indicates antepartum hemorrhage and a co-existing, but unspecified, coagulation disorder is identified as the cause. This code is appropriate when the specific trimester of the hemorrhage is not documented.

• Ensure documentation clearly links the hemorrhage to a coagulation defect, even if unspecified.
• Avoid using this code if the specific trimester is known; instead, select the trimester-specific code (O46.01x, O46.02x, O46.03x).
• Code any specific coagulation defect separately if identified, in addition to this code.
