ICD-10-CM O04.87
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

O04.87 is a billable ICD-10-CM diagnosis code for sepsis following (induced) 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 311 closely related codes. The code is restricted by the Medicare Code Editor to maternity cases (age 9 through 64). Coders also document this condition as induced termination of pregnancy complicated by infectious disease. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Induced abortion and complications of termination of pregnancy and Septicemia.

Questions About O04.87Overview

What is the ICD-10 code for sepsis following (induced) termination of pregnancy?

The ICD-10-CM code for sepsis following (induced) termination of pregnancy is O04.87 (sometimes written as O0487). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is O04.87 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report sepsis following (induced) termination of pregnancy on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does O04.87 group to?

When sepsis following (induced) 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 O04.87 a CC or MCC?

CMS lists O04.87 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 311 closely related codes in its exclusion list.

Who can O04.87 be reported for?
