2025 ICD-10-CM code O10.312
Pre-existing hypertensive heart and chronic kidney disease complicating pregnancy, second trimester.
Medical necessity is established by the presence of pre-existing hypertensive heart and chronic kidney disease in a pregnant woman. The specific medical necessity requirements would depend on the patient's individual circumstances and the severity of her conditions.
The provider is responsible for assessing and managing the patient's pre-existing hypertensive heart and chronic kidney disease throughout the pregnancy. This involves close monitoring of blood pressure, kidney function, and overall maternal health, and appropriate interventions to minimize risks to both the mother and the fetus. Additional codes should be used to identify the specific type of hypertensive heart and chronic kidney disease (I13) and the specific week of gestation (Z3A).
- 15 Pregnancy, childbirth and the puerperium (O00-O9A)
- Edema, proteinuria and hypertensive disorders in pregnancy, childbirth and the puerperium (O10-O16)
In simple words: A pregnant woman in her second trimester (14-28 weeks) has a history of heart problems due to high blood pressure and chronic kidney disease. These conditions existed before she got pregnant.
The patient has a pre-existing condition of hypertensive heart and chronic kidney disease, and is currently in her second trimester of pregnancy.This code should only be used on the maternal record, not the newborn's record.
Example 1: A 20-year-old female, 18 weeks pregnant, presents for a routine prenatal check-up. Her medical history includes chronic kidney disease and hypertension. She is currently being monitored for any complications related to her pre-existing conditions during the pregnancy., A 32-year-old female at 22 weeks gestation is admitted to the hospital with worsening hypertension. She has a history of hypertensive heart disease and chronic kidney disease stage 3. The physician manages her condition with medication and monitoring, aiming for a safe delivery., A 35-year-old pregnant woman at 16 weeks gestation with pre-existing hypertensive heart disease and chronic kidney disease develops severe pre-eclampsia. The code O10.312 is not used; instead, code O11.- is used for the superimposed pre-eclampsia. The underlying hypertensive heart and chronic kidney disease would be coded separately with the appropriate I13 code.
Documentation should include the patient’s trimester, the specific week of gestation (if known), severity of both the heart and kidney conditions, symptoms, type of hypertension and chronic kidney disease, and any associated complications.
** This code is specifically for pre-existing hypertension and chronic kidney disease complicating pregnancy in the second trimester. It excludes superimposed pre-eclampsia (O11.-).
