ICD-10-CM O07.0
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

O07.0 is a billable ICD-10-CM diagnosis code for genital tract and pelvic infection following failed attempted termination of pregnancy. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 770, 779. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 305 closely related codes. The code is restricted by the Medicare Code Editor to maternity cases (age 9 through 64). In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Induced abortion and complications of termination of pregnancy.

Questions About O07.0Overview

Is O07.0 (Failed attempted termination of pregnancy) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report genital tract and pelvic infection following failed attempted termination of pregnancy on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does O07.0 group to?

When genital tract and pelvic infection following failed attempted termination of pregnancy is the principal diagnosis on an inpatient stay, it groups to MS-DRG 779, 770, with relative weights from 1.0198 to 1.0987 depending on complications. Higher weights mean higher Medicare reimbursement.

Is O07.0 a CC or MCC?

CMS lists O07.0 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 305 closely related codes in its exclusion list.

Who can O07.0 be reported for?

The Medicare Code Editor checks genital tract and pelvic infection following failed attempted termination of pregnancy against patient demographics: this code is intended for maternity cases (age 9 through 64). Claims outside these limits are flagged as inconsistent.

Can O07.0 be reported with O07.37?

Not as a rule. The Excludes1 note on O07.0 lists "sepsis following failed attempted termination of pregnancy (O07.37)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
