O04.7Embolism following (induced) termination of pregnancy

O04.7 is the ICD-10-CM diagnosis code for embolism following (induced) termination of pregnancy. It belongs to category O04 (complications following (induced) 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 O04 (complications following (induced) termination of pregnancy), O04.7 is specifically for embolism following (induced) termination of pregnancy. Related codes cover genital tract and pelvic infection following (induced) termination of pregnancy (O04.5), delayed or excessive hemorrhage following (induced) termination of pregnancy (O04.6) and (Induced) termination of pregnancy with other and unspecified complications (O04.8).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.

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 635.62 (Legally induced abortion, complicated by embolism, complete).
