O03.3Other and unspecified complications following incomplete spontaneous abortion

O03.3 is the ICD-10-CM diagnosis code for other and unspecified complications following incomplete spontaneous abortion. It belongs to category O03 (spontaneous abortion), block O00-O08 (pregnancy with abortive outcome) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

Within O03, choose O03.3 (Other and unspecified complications following incomplete spontaneous abortion) only when documentation doesn't support a more specific option: genital tract and pelvic infection following incomplete spontaneous abortion (O03.0), delayed or excessive hemorrhage following incomplete spontaneous abortion (O03.1), embolism following incomplete spontaneous abortion (O03.2), incomplete spontaneous abortion without complication (O03.4), genital tract and pelvic infection following complete or unspecified spontaneous abortion (O03.5), delayed or excessive hemorrhage following complete or unspecified spontaneous abortion (O03.6), embolism following complete or unspecified spontaneous abortion (O03.7), other and unspecified complications following complete or unspecified spontaneous abortion (O03.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: O03.30 (abortion), O03.31 (abortion), O03.32 (abortion), O03.33 (abortion), O03.34 (abortion), O03.35 (abortion), O03.36 (abortion), O03.37 (abortion) and 2 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
