Maternal care for other conditions predominantly related to pregnancy (O26)
The ICD-10 code section O26 covers maternal care for a variety of conditions predominantly related to pregnancy that require specialized monitoring and management. These codes address complications such as excessive or low weight gain, recurrent pregnancy loss, retained intrauterine contraceptive devices, and specific disorders like herpes gestationis or maternal hypotension syndrome during different trimesters.
This section is used to classify pregnancy-related health issues that might affect maternal wellbeing or pregnancy outcomes. For example, the code O26.00 corresponds to "excessive weight gain during pregnancy," often called high maternal weight gain, while O26.10 denotes "low maternal weight gain," both important for tracking nutritional status across trimesters. Conditions such as intrahepatic cholestasis (O26.64) and pruritic urticarial papules and plaques of pregnancy (PUPPP, O26.86) have their own codes to guide appropriate care. Codes like O26.849 highlight discrepancies in uterine size relative to gestation age ("large-for-dates" or "small-for-dates" uterus). This section also includes codes for pregnancy-related exhaustion, peripheral neuritis, renal disease, cervical shortening, and spotting during pregnancy. Using these codes ensures accurate documentation of maternal complications affecting prenatal, childbirth, or postpartum care phases.

Pregnancy complication where fetal blood vessels, normally inside the umbilical cord, are left unprotected and cross FETAL MEMBRANES. It is associated with antepartum bleeding and FETAL DEATH and STILLBIRTH due to exsanguination.
