Clinical Information
Heat Stress Disorders
a group of conditions that develop due to overexposure or overexertion in excessive environmental heat.Syncope
a transient loss of consciousness and postural tone caused by diminished blood flow to the brain (i.e., brain ischemia). presyncope refers to the sensation of lightheadedness and loss of strength that precedes a syncopal event or accompanies an incomplete syncope. (from adams et al., principles of neurology, 6th ed, pp367-9)Syncope, Vasovagal
loss of consciousness due to a reduction in blood pressure that is associated with an increase in vagal tone and peripheral vasodilation.Brain Ischemia
localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. this frequently occurs in conjunction with brain hypoxia (hypoxia, brain). prolonged ischemia is associated with brain infarction.Collapse
failure of a physiologic function or system.Collapse of Device|Collapse
problem associated with the buckling or crushing of material from external forces.Collapsed Lumen|COLLAPSED LUMEN
a finding in which the walls of a tube or tubular organ have contorted or buckled into its cavity or channel.Collapsed Lung
atelectasis of an entire lung.Device Collapser
a component designed to fold or collapse something.Difficult to Fold or Unfold|Difficult to Fold, Unfold or Collapse
problem associated with the use of the device in terms of the user experiencing difficulty to close or to spread out/extend length of the device, even if the operation is being performed according to labeled instructions for use.Inferior Vena Cava Collapse Due to Sniff Test Indicator|IVCCSIND|Inferior Vena Cava Collapse Indicator|Inferior Vena Cava Collapse Sniff Ind|Inferior Vena Cava Collapse Sniff Ind
an indication as to whether resting inferior vena cava diameter is reduced with sniff, which is defined as a sharp inhalation.Shock|Circulatory Collapse
a life-threatening condition that requires immediate medical intervention. it is characterized by reduced blood flow that may result in damage of multiple organs. types of shock include cardiogenic, hemorrhagic, septic, anaphylactic, and traumatic shock.
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.
Inclusion Terms
Inclusion TermsThese 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.
- Blackout
- Fainting
- Vasovagal attack
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.

Patient Education
Fainting
Fainting is a temporary loss of consciousness. If you're about to faint, you'll feel dizzy, lightheaded, or nauseous. Your field of vision may "white out" or "black out." Your skin may be cold and clammy. You lose muscle control at the same time, and may fall down.
Fainting usually happens when your blood pressure drops suddenly, causing a decrease in blood flow to your brain. It is more common in older people. Some causes of fainting include:
- Heat or dehydration
- Emotional distress
- Standing up too quickly
- Certain medicines
- Drop in blood sugar
- Heart problems
When someone faints, make sure that the airway is clear and check for breathing. The person should stay lying down for 10-15 minutes. Most people recover completely. Fainting is usually nothing to worry about, but it can sometimes be a sign of a serious problem. If you faint, it's important to see your health care provider and find out why it happened.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
