About O08.4
O08.4 is the ICD-10-CM diagnosis code for renal failure 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 (complications following ectopic and molar pregnancy), O08.4 is specifically for renal failure following ectopic and molar pregnancy. Related codes cover genital tract and pelvic infection following ectopic and molar pregnancy (O08.0), delayed or excessive hemorrhage following ectopic and molar pregnancy (O08.1), embolism following ectopic and molar pregnancy (O08.2), shock following ectopic and molar pregnancy (O08.3), metabolic disorders following an ectopic and molar pregnancy (O08.5), damage to pelvic organs and tissues following an ectopic and molar pregnancy (O08.6), other venous complications following an ectopic and molar pregnancy (O08.7), other complications following an ectopic and molar pregnancy (O08.8) and 1 more.
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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 639.3 (kidney failure following abortion and ectopic and molar pregnancies).
