About the O85–O92 Code Range
ICD-10 codes O85-O92 address complications occurring predominantly during the puerperium, the period following childbirth. This range specifically covers infections, venous and embolic issues, anesthesia-related problems, wound complications, and various breast and lactation disorders related to pregnancy, childbirth, and the postnatal phase.
The codes from O85 define puerperal sepsis and other infections following delivery, including detailed classifications for infections of obstetric surgical wounds (postoperative wound infection), genital tract infections such as cervicitis and endometritis, and urinary tract infections after childbirth. Codes O87 focus on venous complications like superficial and deep thrombophlebitis, hemorrhoids, and cerebral venous thrombosis. Obstetric embolisms are covered under O88, including amniotic fluid embolism and air embolism occurring during pregnancy, childbirth, or puerperium. Complications related to anesthesia during the puerperium are found in O89, such as aspiration pneumonitis and toxic reactions to local anesthesia. Code group O90 details other puerperal complications not elsewhere classified, including wound disruption, postpartum cardiomyopathy, acute kidney failure, mood disturbances, and anemia. Finally, O91 and O92 cover infections and disorders of the breast and lactation associated with pregnancy and postpartum, such as mastitis, abscesses, cracked or retracted nipples, agalactia, and galactorrhea. These codes help precisely document postpartum health issues, supporting thorough patient care and accurate health records.
