About Z33.2

Z33.2 is the ICD-10-CM diagnosis code for encounter for elective termination of pregnancy. It belongs to category Z33 (Pregnant state), block Z30-Z39 (persons encountering health services in circumstances related to reproduction) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z33 (Pregnant state), Z33.2 is specifically for encounter for elective termination of pregnancy. Related codes cover incidental (Z33.1) and gestational carrier (Z33.3).

Don't report Z33.2 together with the conditions in its Excludes1 note: early fetal death with retention of dead fetus (O02.1), late fetal death (O36.4) and spontaneous abortion (O03).

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 635.90 (Legally induced abortion, without mention of complication, unspecified).
