About O72.3
O72.3 is the ICD-10-CM diagnosis code for postpartum coagulation defects. It belongs to category O72 (postpartum hemorrhage), block O60-O77 (complications of labor and delivery) 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 O72 (postpartum hemorrhage), O72.3 is specifically for postpartum coagulation defects. Related codes cover Third-stage hemorrhage (O72.0), other immediate postpartum hemorrhage (O72.1) and delayed and secondary postpartum hemorrhage (O72.2).
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 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 666.32 (postpartum coagulation defects, delivered, with mention of postpartum complication) and 666.34 (postpartum coagulation defects, postpartum condition or complication).
