2022 ICD-10-CM Code I95.1

Orthostatic hypotension

Version 2021

Valid for Submission

ICD-10:I95.1
Short Description:Orthostatic hypotension
Long Description:Orthostatic hypotension

Code Classification

  • Diseases of the circulatory system (I00–I99)
    • Other and unspecified disorders of the circulatory system (I95-I99)
      • Hypotension (I95)

I95.1 is a billable diagnosis code used to specify a medical diagnosis of orthostatic hypotension. The code I95.1 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code I95.1 might also be used to specify conditions or terms like chronic hypotension, chronic orthostatic hypotension, hyperadrenergic postural hypotension, hypoadrenergic postural hypotension, hypotensive syncope , orthostatic hypotension, etc.

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 I95.1:


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Type 1 Excludes

Type 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.

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code I95.1 are found in the index:

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Information for Patients


Autonomic Nervous System Disorders

Your autonomic nervous system is the part of your nervous system that controls involuntary actions, such as the beating of your heart and the widening or narrowing of your blood vessels. When something goes wrong in this system, it can cause serious problems, including

Autonomic nervous system disorders can occur alone or as the result of another disease, such as Parkinson's disease, alcoholism and diabetes. Problems can affect either part of the system, as in complex regional pain syndromes, or all of the system. Some types are temporary, but many worsen over time. When they affect your breathing or heart function, these disorders can be life-threatening.

Some autonomic nervous system disorders get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms.

Orthostatic hypotension

Orthostatic hypotension is a drop in blood pressure that occurs when moving from a laying down (supine) position to a standing (upright) position. The word "orthostasis" means to stand up, so the condition is defined as low blood pressure (hypotension) that occurs upon standing.

When standing up, gravity moves blood from the upper body to the lower limbs. As a result, there is a temporary reduction in the amount of blood in the upper body for the heart to pump (cardiac output), which decreases blood pressure. Normally, the body quickly counteracts the force of gravity and maintains stable blood pressure and blood flow. In most people, this transient drop in blood pressure goes unnoticed. However, this transient orthostatic hypotension can cause lightheadedness that may result in falls and injury, particularly in older adults.

The body has difficulty achieving stable blood pressure in people with orthostatic hypotension, resulting in a prolonged drop in blood pressure that occurs within minutes after moving from laying down to standing. The vast majority of people with orthostatic hypotension do not experience symptoms related to the condition; it may be detected incidentally during routine medical testing. When measuring blood pressure, orthostatic hypotension is defined as a decrease in blood pressure by at least 20mmHg systolic or 10mmHg diastolic within 3 minutes of standing.

When signs and symptoms of orthostatic hypotension do occur, they are usually the result of a reduction in blood flow (hypoperfusion) to tissues, particularly the brain. Affected individuals may have fatigue, confusion, dizziness, blurred vision, or fainting episodes (syncope). Less frequently, affected individuals can experience muscle pain in the neck and shoulders (known as "coat hanger pain"), lower back pain, or weakness. During an episode of orthostatic hypotension, symptoms are often increased in severity by physical activity, warm temperatures, eating large meals, or standing for long periods of time.

In people with orthostatic hypotension, hypoperfusion to other organs contributes to an increased risk of life-threatening health problems, including heart attack or heart failure, a heart rhythm abnormality called atrial fibrillation, stroke, or chronic kidney failure. Additionally, affected individuals may get injured from falls during fainting episodes.
