Not Valid for Submission
I12 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of hypertensive chronic kidney disease. The code is not specific and is NOT valid for the year 2021 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 for Hypertensive chronic kidney disease
Non-specific codes like I12 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for hypertensive chronic kidney disease:
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I12:
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- any condition in N18 N26
- arteriosclerosis of kidney
- arteriosclerotic nephritis (chronic) (interstitial)
- hypertensive nephropathy
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- hypertension due to kidney disease I15.0 I15.1
- renovascular hypertension I15.0
- secondary hypertension I15
Type 2 ExcludesType 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- acute kidney failure N17
Information for Patients
Chronic Kidney Disease
Also called: CKD
You have two kidneys, each about the size of your fist. Their main job is to filter your blood. They remove wastes and extra water, which become urine. They also keep the body's chemicals balanced, help control blood pressure, and make hormones.
Chronic kidney disease (CKD) means that your kidneys are damaged and can't filter blood as they should. This damage can cause wastes to build up in your body. It can also cause other problems that can harm your health. Diabetes and high blood pressure are the most common causes of CKD.
The kidney damage occurs slowly over many years. Many people don't have any symptoms until their kidney disease is very advanced. Blood and urine tests are the only way to know if you have kidney disease.
Treatments cannot cure kidney disease, but they may slow kidney disease. They include medicines to lower blood pressure, control blood sugar, and lower cholesterol. CKD may still get worse over time. Sometimes it can lead to kidney failure. If your kidneys fail, you will need dialysis or a kidney transplantation.
You can take steps to keep your kidneys healthier longer:
- Choose foods with less salt (sodium)
- Control your blood pressure; your health care provider can tell you what your blood pressure should be
- Keep your blood sugar in the target range, if you have diabetes
- Limit the amount of alcohol you drink
- Choose foods that are healthy for your heart: fruits, vegetables, whole grains, and low-fat dairy foods
- Lose weight if you are overweight
- Be physically active
- Don't smoke

High Blood Pressure
Also called: Benign essential hypertension, Essential hypertension, HBP, HTN, Hypertension
What is blood pressure?
Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
Your blood pressure reading uses these two numbers. Usually the systolic number comes before or above the diastolic number. For example, 120/80 means a systolic of 120 and a diastolic of 80.
How is high blood pressure diagnosed?
High blood pressure usually has no symptoms. So the only way to find out if you have it is to get regular blood pressure checks from your health care provider. Your provider will use a gauge, a stethoscope or electronic sensor, and a blood pressure cuff. He or she will take two or more readings at separate appointments before making a diagnosis.
You have high blood pressure if your readings show that
- Your systolic is 140 or higher OR
- Your diastolic is 90 or higher
Some providers may consider you to have high blood pressure if you have other heart risk factors and
- Your systolic is between 130 and 139 OR
- Your diastolic is between 80 and 89
Blood pressure readings above 180 /120 are dangerously high and require immediate medical attention.
For children and teens, the health care provider compares the blood pressure reading to what is normal for other kids who are the same age, height, and gender.
What are the different types of high blood pressure?
There are two main types of high blood pressure: primary and secondary high blood pressure.
- Primary, or essential, high blood pressure is the most common type of high blood pressure. For most people who get this kind of blood pressure, it develops over time as you get older.
- Secondary high blood pressure is caused by another medical condition or use of certain medicines. It usually gets better after you treat that condition or stop taking the medicines that are causing it.
Why do I need to worry about high blood pressure?
When your blood pressure stays high over time, it causes the heart to pump harder and work overtime, possibly leading to serious health problems such as heart attack, stroke, heart failure, and kidney failure.
What are the treatments for high blood pressure?
Treatments for high blood pressure include heart-healthy lifestyle changes and medicines.
You will work with your provider to come up with a treatment plan. It may include only the lifestyle changes. These changes, such as heart-healthy eating and exercise, can be very effective. But sometimes the changes do not control or lower your high blood pressure. Then you may need to take medicine. There are different types of blood pressure medicines. Some people need to take more than one type.
If your high blood pressure is caused by another medical condition or medicine, treating that condition or stopping the medicine may lower your blood pressure.
