About O08.82

O08.82 is the ICD-10-CM diagnosis code for sepsis following ectopic and molar pregnancy. It belongs to category O08 (complications following ectopic and molar 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 O08.8 (other complications following an ectopic and molar pregnancy), O08.82 is specifically for sepsis following ectopic and molar pregnancy. Related codes cover cardiac arrest following an ectopic and molar pregnancy (O08.81), urinary tract infection following an ectopic and molar pregnancy (O08.83) and other complications following an ectopic and molar pregnancy (O08.89).

Don't report O08.82 together with the conditions in its Excludes1 note: septic or septicopyemic embolism following ectopic and molar pregnancy (O08.2).

Use an additional code (B95-B97), to identify infectious agent. Use an additional code (R65.2-) to identify severe sepsis, if applicable.

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 769 (Postpartum and Post Abortion Diagnoses with O.R. Procedures, relative weight 1.6673) and DRG 776 (Postpartum and Post Abortion Diagnoses without O.R. Procedures, relative weight 0.6721), 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 639.0 (genital tract and pelvic infection following abortion or ectopic and molar pregnancies).
