What are Gestational Hypertension ICD-10-CM Codes?
The general code for gestational hypertension is O13. This code is used for pregnant women with elevated blood pressure (>140/90 mm Hg) on at least two occasions. This form of gestational pregnancy induced hypertension is categorized under the ICD-10 system for accurate diagnosis and billing.
If you're looking for gestational hypertension ICD codes, here are six that you can use:
O13.1 - Gestational [pregnancy-induced] hypertension without significant proteinuria, first trimester
This ICD-10 code is meant to be used on female patients confirmed to have gestational hypertension during the first trimester of their pregnancy. Their gestational hypertension is not accompanied by significant proteinuria (elevated protein levels in urine). This falls under gestational hypertension icd 10 classification and is managed by monitoring blood pressure and possible gestational diabetes mellitus risk.
O13.2 - Gestational [pregnancy-induced] hypertension without significant proteinuria, second trimester
This code is used when hypertension develops during the second trimester of pregnancy, and there is no significant proteinuria. It represents pregnancy induced hypertension without complications like moderate pre eclampsia or pre existing hypertension.
O13.3 - Gestational [pregnancy-induced] hypertension without significant proteinuria, third trimester
This code is used when hypertension develops during the third trimester of pregnancy, with high blood pressure but without significant proteinuria complicating the condition. This is common in patients not exhibiting severe pre or gestational edema with proteinuria.
O13.4 - Gestational [pregnancy-induced] hypertension without significant proteinuria, complicating childbirth
This ICD-10 code is meant to be used on a female patient with gestational hypertension that's complicating childbirth. It is when induced hypertension without significant proteinuria disrupts normal delivery, often requiring close monitoring and possibly treatment with anti-hypertensive medication.
O13.5 - Gestational [pregnancy-induced] hypertension without significant proteinuria, complicating the puerperium
This ICD-10 code is meant to be used on a female patient confirmed to have gestational hypertension that complicates the puerperium (the period when the reproductive organs return to normal post-childbirth). Their gestational hypertension is not accompanied by significant proteinuria, but proteinuria complicating the puerperium can develop in more severe cases. This should not be confused with pre existing secondary hypertension.
O13.9 - Gestational [pregnancy-induced] hypertension without significant proteinuria, unspecified trimester
This ICD-10 code is used when the trimester is unspecified or undocumented, typically for pregnancy induced hypertension arising after 20 weeks gestation without significant proteinuria, complicating childbirth and the puerperium. It may coexist with gestational edema and is sometimes documented with unspecified pre or pre existing hypertensive conditions.
