About O04.85

O04.85 is the ICD-10-CM diagnosis code for other venous complications 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 O04.8, choose O04.85 (Other venous complications following (induced) termination of pregnancy) only when documentation doesn't support a more specific option: (Induced) termination of pregnancy with unspecified complications (O04.80), shock following (induced) termination of pregnancy (O04.81), renal failure following (induced) termination of pregnancy (O04.82), metabolic disorder following (induced) termination of pregnancy (O04.83), damage to pelvic organs following (induced) termination of pregnancy (O04.84), cardiac arrest following (induced) termination of pregnancy (O04.86), sepsis following (induced) termination of pregnancy (O04.87), urinary tract infection following (induced) termination of pregnancy (O04.88) and 1 more.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" 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 635.72 (Legally induced abortion, with other specified complications, complete).
