2024 ICD-10-CM Diagnosis Code I1A
Other hypertension
- ICD-10-CM Code:
- I1A
- ICD-10 Code for:
- Other hypertension
- Is Billable?
- Not Valid for Submission
- Code Navigator:
I1A is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other hypertension. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
Specific Coding Applicable to Other hypertension
Non-specific codes like I1A require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for other hypertension:

Clinical Information
Essential Hypertension
hypertension that occurs without known cause, or preexisting renal disease. associated polymorphisms for a number of genes have been identified, including agt, gnb3, and ece1. omim: 145500Familial Primary Pulmonary Hypertension
familial or idiopathic hypertension in the pulmonary circulation which is not secondary to other disease.Hypertension
persistently high systemic arterial blood pressure. based on multiple readings (blood pressure determination), hypertension is currently defined as when systolic pressure is consistently greater than 140 mm hg or when diastolic pressure is consistently 90 mm hg or more.Hypertension, Malignant
a condition of markedly elevated blood pressure with diastolic pressure usually greater than 120 mm hg. malignant hypertension is characterized by widespread vascular damage, papilledema, retinopathy, hypertensive encephalopathy, and renal dysfunction.Hypertension, Portal
abnormal increase of resistance to blood flow within the hepatic portal system, frequently seen in liver cirrhosis and conditions with obstruction of the portal vein.Hypertension, Pregnancy-Induced
a condition in pregnant women with elevated systolic (>140 mm hg) and diastolic (>90 mm hg) blood pressure on at least two occasions 6 h apart. hypertension complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as edema; proteinuria; seizures; abnormalities in blood coagulation and liver functions.Hypertension, Pulmonary
increased vascular resistance in the pulmonary circulation, usually secondary to heart diseases or lung diseases.Hypertension, Renal
persistent high blood pressure due to kidney diseases, such as those involving the renal parenchyma, the renal vasculature, or tumors that secrete renin.Hypertension, Renovascular
hypertension due to renal artery obstruction or compression.Idiopathic Noncirrhotic Portal Hypertension
portal hypertension without known risk factors for hypertension, e.g., hepatic cirrhosis and schistosomiasis. idiopathic noncirrhotic portal hypertension is most often associated with pathology in the portal system vasculature.Intra-Abdominal Hypertension
pathological elevation of intra-abdominal pressure (>12 mm hg). it may develop as a result of sepsis; pancreatitis; capillary leaks, burns, or surgery. when the pressure is higher than 20 mm hg, often with end-organ dysfunction, it is referred to as abdominal compartment syndrome.Intracranial Hypertension
increased pressure within the cranial vault. this may result from several conditions, including hydrocephalus; brain edema; intracranial masses; severe systemic hypertension; pseudotumor cerebri; and other disorders.Isolated Systolic Hypertension
hypertension with elevated systolic and normal diastolic blood pressure. it is the most common subtype in the elderly and is related to vascular stiffness and atherosclerotic plaque buildup.Masked Hypertension
phenomenon where increased blood pressure readings taken in non-clinical settings (e.g., home blood pressure monitoring) do not replicate in clinical settings.Ocular Hypertension
a condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.Persistent Fetal Circulation Syndrome
a syndrome of persistent pulmonary hypertension in the newborn infant (infant, newborn) without demonstrable heart diseases. this neonatal condition can be caused by severe pulmonary vasoconstriction (reactive type), hypertrophy of pulmonary arterial muscle (hypertrophic type), or abnormally developed pulmonary arterioles (hypoplastic type). the newborn patient exhibits cyanosis and acidosis due to the persistence of fetal circulatory pattern of right-to-left shunting of blood through a patent ductus arteriosus (ductus arteriosus, patent) and at times a patent foramen ovale (foramen ovale, patent).Pre-Eclampsia
a complication of pregnancy, characterized by a complex of symptoms including maternal hypertension and proteinuria with or without pathological edema. symptoms may range between mild and severe. pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.Pseudotumor Cerebri
a condition marked by raised intracranial pressure and characterized clinically by headaches; nausea; papilledema, peripheral constriction of the visual fields, transient visual obscurations, and pulsatile tinnitus. obesity is frequently associated with this condition, which primarily affects women between 20 and 44 years of age. chronic papilledema may lead to optic nerve injury (see optic nerve diseases) and visual loss (see blindness).Pulmonary Arterial Hypertension
a progressive rare pulmonary disease characterized by high blood pressure in the pulmonary artery.Sinistral Portal Hypertension
portal hypertension of the splenic vein due to occlusion caused by pancreatic pathology such as pancreatic pseudocyst and pancratic cancer. sinistral portal hypertension is associated with gastric varices and acute hematemesis.Varicose Ulcer
skin breakdown or ulceration in the drainage area of a varicose vein, usually in the leg.White Coat Hypertension
phenomenon where blood pressure readings are elevated only when taken in clinical settings.Pulmonary Circulation
the circulation of the blood through the lungs.Renal Artery Obstruction
narrowing or occlusion of the renal artery or arteries. it is due usually to atherosclerosis; fibromuscular dysplasia; thrombosis; embolism, or external pressure. the reduced renal perfusion can lead to renovascular hypertension (hypertension, renovascular).Pulmonary Artery
the short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs.Varicose Veins
enlarged and tortuous veins.Blood Pressure
pressure of the blood on the arteries and other blood vessels.
New 2024 ICD-10-CM Code
I1A is new to ICD-10-CM code set for the FY 2024, effective October 1, 2023. The National Center for Health Statistics (NCHS) has published an update to the ICD-10-CM diagnosis codes which became effective October 1, 2023. This is a new and revised code for the FY 2024 (October 1, 2023 - September 30, 2024).
Code History
