(2022) How To Code Hypotension ICD 10 – List With Codes & Guidelines

Hypotension ICD 10 coding is made easier with our billing guidelines. This article includes all medical codes you will need to report hypotension and related specific ICD 10 codes such as orthostatic hypotension and new postpartum hypotension. Read on to get a summary of the necessary ICD 10 & 11 codes followed by a further description.

How To Code Hypotension

The following information will enable you to understand how to code hypotension using ICD 10 & 11.

What Is Hypotension?

It is otherwise known as low blood pressure and is described as blood pressure <90/60, the patient most times does not present with any symptoms,

in a situation where the blood pressure is low enough to cause a reduced flow of blood to organs, symptoms, or signs could manifest, presence of symptoms could be unpleasant,

it can occur both as a situation on its very own or as a symptom of a huge range of conditions.

Hypotension has definitions:

Absolute hypotension: Your resting blood pressure is under 90/60 mmHg (millimeters of mercury).

Orthostatic hypotension: Your blood pressure drops within three minutes of your status up from a sitting function. also known as postural hypotension.

Measuring blood pressure involves considering two values, top, and bottom, in MM/Hg.

Systolic value (Top number): Your systolic pressure is the stress on your arteries your heart beats every time.

Diastolic value (Bottom number): Diastolic pressure is how much stress the arteries experience between heartbeats.

The most common symptoms of low blood pressure are because your brain is not getting enough blood flow.

These include:

  • Dizziness or lightheadedness.
  • Fainting (syncope).
  • Nausea or vomiting.
  • Blurred or distorted vision.
  • Fast, shallow breathing.
  • Fatigue or weakness.
  • Feeling tired.
  • Confusion or focus on the problem.
  • Unrest or other abnormal behavioural changes (a person who does not act like him).

What Causes Low Blood Pressure?

The cause of low blood pressure is not always clear. It may be associated with the following:

  • Pregnancy
  • Hormonal problems such as hypothyroidism, diabetes, or low blood sugar (hypoglycemia)
  • Some of the drugs available off the counter
  • Other prescription drugs such as antihypertensive, antidepressant
  • Heart failure
  • Cardiac arrhythmias (abnormal heart rhythm
  • Excessive blood loss
  • Dehydration

Treatment is by attending to the underlying cause.

Hypotension ICD 10

Hypotension ICD 10 is coded as I95 – a billable/specific ICD 10 CM code that can indicate a diagnosis for reimbursement purposes.

It is located in chapter IX Diseases of the circulatory system I00-I99 of ICD 10under block Other and unspecified disorders of the circulatory system I95-I99, category Hypotension I95-, which includes:

Idiopathic hypotension I95.0

Orthostatic hypotension I95.1

Hypotension due to drug I95.2

Hypotension of hemodialysis I195.3

Postprocedural hypotension I95.81

Other hypotension I95.89

Hypotension unspecified I95.9

icd 10 code for hypotension
ICD 10 code I95 Hypotension.

Orthostatic Hypotension ICD 10

Orthostatic hypotension ICD 10 is coded as I95.1. Otherwise known as postural hypotension, it is a billable code located in chapter IX Diseases of the circulatory system I00-I99 of ICD 10

under block Other and unspecified disorders of the circulatory system I95-I99, category Hypotension I95-.


Neurogenic orthostatic hypotension [Shy-Drager] (G90.3)

Orthostatic hypotension due to drugs (I95.2)

Cardiovascular collapse (R57.9)

Maternal hypotension syndrome (O26.5-)

Nonspecific low blood pressure reading NOS (R03.1)

Transient Hypotension ICD 10

Transient hypotension ICD 10 is coded as I95.89 other hypotension.

It is a billable code located in chapter IX Diseases of the circulatory system I00-I99, under block Other and unspecified disorders of the circulatory system I95-I99, category Hypotension I95-.

Chronic Hypotension ICD10

Chronic hypotension ICD 10 is coded as I95.89. Check the above information on locating it in the ICD 10 manual.

Hence If your blood pressure is far above 120/80 mmHg, it means that the resistance is high, and your heart has to work hard to pump blood into your body.

At this point, your physician may recommend that you try some lifestyle changes to reduce your risk of coming down with complications such as stroke, renal failure etc.

These can include weight loss, exercise, and reduced salt intake.

Neurogenic Orthostatic Hypotension ICD 10

Neurogenic orthostatic hypotension is coded as (G90.3), it is a billable code located in chapter VI disease of the nervous system G00-G99, 

under block other disorders of the nervous system G89-G99, category disorders of autonomic nervous system G90-, subcategory multi-system degeneration of the autonomic nervous system.

It is a unique and treatable symptom of cardiovascular dysfunction. It is caused by a failure of noradrenergic neurotransmission associated with a list of primary or secondary independent disorders.

Its frequency increases with age and is often associated with neurodegenerative diseases, including Parkinson’s disease (PD), dementia Lewy (DLB), multiple system atrophy (MSA), and autonomic failure (PAF).

Persistent Hypotension

Currently, no code exists to describe the literality of persistent hypotension. However, it can be coded as I95-.

Episodic Hypotension

Currently, no code exists to describe the literality of episodic hypotension.

Therefore, episodic hypotension is coded as I95.9 hypotension unspecified.

Congestive Heart Failure With Hypotension ICD 10

Congestive heart failure with hypotension is coded as I50.20 unspecified systolic (congestive) heart failure, located in chapter IX Diseases of the circulatory system I00-I99,

under block other forms of heart disease I30-I5A, category heart failure I50-, in the presence of systolic failure where inadequate blood is pumped into systemic circulation hypotension could ensue as a complication.

Hence double diagnoses are made, both conditions are coded for accordingly, systolic heart failure is coded as I50.20, and hypotension is coded as I95-.

ICD 10 Code For Threatened Shock Patient With Hypotension 

Shock often arises as a complication of hypotension. Your body is in a state of shock when you do not have enough blood circulating in your system to keep your organs and tissues working properly.

It can be caused by an injury or condition that affects blood flow in your body. It can lead to many organ failure and life-threatening complications.

It is coded as R57.9 shock unspecified, located in chapter XVIII Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified R00-R99, under block general symptoms and sign R50-R69, 

category shock not elsewhere classified R57-, in a patient with shock due to hypotension both conditions are coded accordingly, unspecified shock as R57.9 hypotension as I95-.

Postpartum Hypotension ICD 10

Pregnancy is a major cause of low blood pressure in itself. During the first 24 weeks of pregnancy, blood pressure is very low.

This is because your body produces high levels of certain hormones such as progesterone, which help lower the contraction force of walls of blood vessels by lowering the resistance offered against blood flow hence lowering blood pressure.

Postpartum hypotension is coded as O26.50 maternal hypotension syndrome unspecified trimester.

It is located in chapter XV pregnancy, childbirth and the puerperium O00-09A, under block other maternal disorders predominantly related to prepregnancy O20-029,

category maternal care for other conditions predominantly related to pregnancy 026-:

Maternal hypotension syndrome first trimester O26.51

Maternal hypotension syndrome second trimester 026.52

Maternal hypotension syndrome second trimester 025.53

Pulmonary Hypotension ICD 10

Currently, no ICD 10 code exists to describe pulmonary hypotension in the manual.

Sepsis Associated Hypotension ICD 10

It begins when an existing infection causes an overactive reaction to your immune system.

When you get infected, your immune system reacts by releasing proteins and other chemicals to fight them. Sepsis occurs when this reaction is out of control, causing severe inflammation.

In severe cases, there could be a significant drop in blood pressure, resulting in a state of hypotension, otherwise known as septic shock.

Hence It is Coded as R65.21 severe sepsis with septic shock, located in chapter XVIII Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified R00-R99, under block General symptoms and signs R50-R69, 

category Symptoms, and signs specifically associated with systemic inflammation and infection R65.

Post Procedural Hypotension

There could be hypotension following a surgical procedure. Hypotension in a postoperative patient can be due to more serious causes such as sepsis, bleeding adrenal gland dysfunction, or heart causes.

It is important to diagnose and treat these conditions, as their persistence can lead to shock, paralysis, and death. In some people, anesthesia during surgical procedures could cause a sharp drop in blood pressure.

If so, doctors will monitor you closely and give Intravenous medications to help restore blood pressure to normal. It is coded as I95.81 is a billable code located in chapter IX Diseases of the circulatory system I00-I99 of ICD 10

under block Other and unspecified disorders of the circulatory system I95-I99, category Hypotension I95-.

  • Idiopathic hypotension BA20
  • Orthostatic hypotension BA21
  • Other specified hypotension BA2Y
  • Hypotension unspecified BA2Z
