O07.4Failed attempted termination of pregnancy without complication

O07.4 is the ICD-10-CM diagnosis code for failed attempted termination of pregnancy without complication. It belongs to category O07 (failed attempted termination of pregnancy), block O00-O08 (pregnancy with abortive outcome) and chapter 15 (pregnancy, childbirth and the puerperium). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within O07, choose O07.4 (without complication) only when documentation doesn't support a more specific option: genital tract and pelvic infection following failed attempted termination of pregnancy (O07.0), delayed or excessive hemorrhage following failed attempted termination of pregnancy (O07.1), embolism following failed attempted termination of pregnancy (O07.2) and with other and unspecified complications (O07.3).

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.

The Medicare Code Editor treats this as a maternity diagnosis, expected only for patients age 9 through 64.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

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

Before ICD-10, this condition was coded in ICD-9-CM as 638.9 (failed attempted abortion without mention of complication).
