Clinical InformationClinical

  • 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.

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:

Questions About I95.1Overview

Is I95.1 (Hypotension) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report orthostatic hypotension on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What is the ICD-9 equivalent of I95.1?

Under the General Equivalence Mappings, orthostatic hypotension converts to ICD-9-CM 458.0 (orthostatic hypotension). The mapping is a direct match.

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.
