2018/2019 ICD-10-CM Diagnosis Code I15.1. Hypertension secondary to other renal disorders. I15.1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
Atherosclerosis of renal artery. I70.1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2018/2019 edition of ICD-10-CM I70.1 became effective on October 1, 2018.
ICD-10 uses only a single code for individuals who meet criteria for hypertension and do not have comorbid heart or kidney disease. That code is I10, Essential (primary) hypertension.
The appropriate code from category N18 should be used as a secondary code with a code from category I12 to identify the stage of chronic kidney disease. If a patient has hypertensive chronic kidney disease and acute renal failure, an additional code for the acute renal failure is required.
It is important to realize that any condition that compromises blood flow to the kidneys can contribute to renovascular hypertension. [3] The most common causes of renovascular hypertension include: Renal artery stenosis (RAS), mostly secondary to atherosclerosis.
In ICD-9, essential hypertension was coded using 401.0 (malignant), 401.1 (benign), or 401.9 (unspecified). ICD-10 uses only a single code for individuals who meet criteria for hypertension and do not have comorbid heart or kidney disease. That code is I10, Essential (primary) hypertension.
401.0 - Malignant essential hypertension. 401.1 - Benign essential hypertension. 401.9 - Unspecified essential hypertension.
Renovascular hypertension is high blood pressure due to narrowing of the arteries that carry blood to the kidneys. This condition is also called renal artery stenosis.
Malignant hypertension is very high blood pressure that comes on suddenly and quickly. The kidneys filter wastes and excrete fluid when the pressure of blood in the bloodstream forces blood through the internal structures of the kidney.
Once hypertension is established by a physician, a code from category 401 is assigned, with a fourth digit required: 0 for malignant, 1 for benign, and 9 for unspecified. Do not assign a code for benign or malignant hypertension unless it is specifically documented by a physician.
What causes malignant hypertension? Uncontrolled high blood pressure is one of the main causes of malignant hypertension. Other causes include: Adrenal disorders including Conn's syndrome, Cushing's syndrome, pheochromocytoma or a renin-secreting tumor.
If hypertension, heart failure and chronic kidney disease are all documented, use a combination code from category I13 — hypertensive heart and chronic kidney disease. These are just a few examples of conditions that have an assumed causal relationship in ICD-10-CM.

In renal artery stenosis, one or both of the arteries leading to the kidneys becomes narrowed, preventing adequate blood flow to the kidneys. Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries).
Renovascular hypertension is high blood pressure (greater than 140/80 mmHg) caused by renal artery disease. Normally, the kidneys regulate body fluid and blood pressure, as well as regulate blood chemistry and remove organic waste.
Definition of renovascular : of, relating to, or involving the blood vessels of the kidneys renovascular hypertension.
Hypertensive Heart and Chronic Kidney Disease: The codes in category I13, Hypertensive heart and chronic kidney disease, are combination codes that include hypertension, heart disease and chronic kidney disease, and should be used when there is hypertension with both heart and kidney involvement.
CKD should not be coded as hypertensive if the physician has specifically documented a different cause. The appropriate code from category N18 should be used as a secondary code with a code from category I12 to identify the stage of chronic kidney disease.
