Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Hypotension

CCSR Code: CIR031

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

Clinical Information

  • Hypotension

    abnormally low blood pressure that can result in inadequate blood flow to the brain and other vital organs. common symptom is dizziness but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.

  • Hypotension, Controlled

    procedure in which arterial blood pressure is intentionally reduced in order to control blood loss during surgery. this procedure is performed either pharmacologically or by pre-surgical removal of blood.

  • Hypotension, Orthostatic

    a significant drop in blood pressure after assuming a standing position. orthostatic hypotension is a finding, and defined as a 20-mm hg decrease in systolic pressure or a 10-mm hg decrease in diastolic pressure 3 minutes after the person has risen from supine to standing. symptoms generally include dizziness, blurred vision, and syncope.

  • Intracranial Hypotension

    reduction of cerebrospinal fluid pressure characterized clinically by orthostatic headache and occasionally by an abducens nerve palsy; hearing loss; nausea; neck stiffness, and other symptoms. this condition may be spontaneous or secondary to cerebrospinal fluid leak; spinal puncture; neurosurgical procedures; dehydration; uremia; trauma (see also craniocerebral trauma); and other processes. chronic hypotension may be associated with subdural hematomas (see hematoma, subdural) or hygromas. (from semin neurol 1996 mar;16(1):5-10; adams et al., principles of neurology, 6th ed, pp637-8)

  • Ocular Hypotension

    abnormally low intraocular pressure often related to chronic inflammation (uveitis).

  • Post-Exercise Hypotension

    transient reduction in blood pressure levels immediately after exercises that lasts 2-12 hours. the reduction varies but is typically 5-20 mm hg when compared to pre-exercise levels. it exists both in normotensive and hypertensive individuals and may play a role in excercise related physiologic adaptation.

  • Shy-Drager Syndrome

    a progressive neurodegenerative condition of the central and autonomic nervous systems characterized by atrophy of the preganglionic lateral horn neurons of the thoracic spinal cord. this disease is generally considered a clinical variant of multiple system atrophy. affected individuals present in the fifth or sixth decade with orthostasis and bladder dysfunction; and later develop fecal incontinence; anhidrosis; ataxia; impotence; and alterations of tone suggestive of basal ganglia dysfunction. (from adams et al., principles of neurology, 6th ed, p536)

  • Adaptation, Physiological

    the non-genetic biological changes of an organism in response to challenges in its environment.

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.

Low Blood Pressure

You've probably heard that high blood pressure is a problem. Sometimes blood pressure that is too low can also cause problems.

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps out 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 the diastolic pressure. Your blood pressure reading uses these two numbers. Usually they're written one above or before the other, such as 120/80. If your blood pressure reading is 90/60 or lower, you have low blood pressure.

Some people have low blood pressure all the time. They have no symptoms and their low readings are normal for them. In other people, blood pressure drops below normal because of a medical condition or certain medicines. Some people may have symptoms of low blood pressure when standing up too quickly. Low blood pressure is a problem only if it causes dizziness, fainting or in extreme cases, shock.

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.
