(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Pregnancy, childbirth and the puerperium - Edema, proteinuria and hypertensive disorders in pregnancy, childbirth and the puerperium (O10-O16) Chapter 10: Pregnancy, childbirth and the puerperium (O00-O9A) Feed
Pre-existing secondary hypertension complicating pregnancy during the first trimester.
Medical necessity for the diagnostic and therapeutic interventions is dependent on the severity and complications of pre-existing hypertension.Monitoring and treatment are essential to prevent serious complications such as preeclampsia, eclampsia, stroke, or heart failure for both the mother and the fetus.
Obstetricians and gynecologists are primarily responsible for managing the hypertensive disorder and its complications during pregnancy.Other specialists such as nephrologists or cardiologists may be consulted depending on the underlying cause of the hypertension or any other associated health problems.
In simple words: This code is used for pregnant women with high blood pressure that started before the pregnancy.It's used only if the high blood pressure is during the first three months of pregnancy (the first trimester).
This code classifies pre-existing secondary hypertension that complicates pregnancy during the first trimester (less than 14 weeks from the first day of the last menstrual period).Secondary hypertension is high blood pressure caused by an underlying medical condition.This code is specifically for use in maternal records and should not be used for newborn records.Additional codes may be used to specify the underlying cause of the hypertension and the gestational week.
Example 1: A 32-year-old woman with a history of chronic kidney disease and secondary hypertension presents at 8 weeks gestation with elevated blood pressure.O10.411 would be used to document the pre-existing secondary hypertension complicating her pregnancy., A 28-year-old woman with a history of pheochromocytoma and controlled hypertension becomes pregnant.At her 10-week checkup, her blood pressure remains elevated despite medication. O10.411 is used, along with codes to specify the underlying pheochromocytoma and the hypertension., A 40-year-old woman with a history of poorly controlled hypertension due to primary aldosteronism becomes pregnant. At 12 weeks gestation, she is admitted to hospital for hypertensive crisis.O10.411 is appropriate, supplemented with codes illustrating the specific cause of hypertension and any complications.
Complete obstetric history including past medical conditions, medications, and family history of hypertension.Detailed documentation of blood pressure readings throughout the pregnancy, any medications taken, and management strategies undertaken.Laboratory results (e.g., serum creatinine, electrolytes, urinalysis) reflecting the kidney function and potential organ damage.Documentation of any complications and their management.
** This code is applicable to women aged 12-55 years inclusive. It is specifically for use on maternal records, never on newborn records.Always refer to the latest version of ICD-10-CM coding guidelines for accurate and compliant coding.
