ICD-10 code for abortion
O03.9

About coding abortion
The ICD-10-CM code for abortion is O03.9 (Complete or unspecified spontaneous abortion without complication). The official index lists 144 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O03.9.
Within O03, choose O03.9 (Complete or unspecified spontaneous abortion without complication) 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), other and unspecified complications following incomplete spontaneous abortion (O03.3), 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) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 770 (Abortion with D&C, Aspiration Curettage or Hysterotomy, relative weight 1.0992) and DRG 779 (Abortion without D&C, relative weight 1.0203), in MDC 14 (Pregnancy, Childbirth and the Puerperium), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
