I15 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of secondary 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 Secondary hypertension
Non-specific codes like I15 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 secondary hypertension:
Use I15.0 for Renovascular hypertension - BILLABLE CODE
Use I15.1 for Hypertension secondary to other renal disorders - BILLABLE CODE
Use I15.2 for Hypertension secondary to endocrine disorders - BILLABLE CODE
Use I15.8 for Other secondary hypertension - BILLABLE CODE
Use I15.9 for Secondary hypertension, unspecified - BILLABLE CODE
Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Code Also
Code AlsoA "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- underlying condition
Type 1 Excludes
Type 1 ExcludesA 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.
- postprocedural hypertension I97.3
Type 2 Excludes
Type 2 ExcludesA 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.

High Blood Pressure
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.
Blood Pressure Category | Systolic Blood Pressure | Diastolic Blood Pressure | |
---|---|---|---|
Normal | Less than 120 | and | Less than 80 |
High Blood Pressure (no other heart risk factors) | 140 or higher | or | 90 or higher |
High Blood Pressure (with other heart risk factors, according to some providers) | 130 or higher | or | 80 or higher |
Dangerously high blood pressure - seek medical care right away | 180 or higher | and | 120 or higher |
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 sex.
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.
