Clinical Classification

Clinical Information

  • Intracranial Aneurysm

    abnormal outpouching in the wall of intracranial blood vessels. most common are the saccular (berry) aneurysms located at branch points in circle of willis at the base of the brain. vessel rupture results in subarachnoid hemorrhage or intracranial hemorrhages. giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the oculomotor nerve. (from adams et al., principles of neurology, 6th ed, p841)
  • Intracranial Aneurysm

    a congenital or acquired aneurysm within the cranium.

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 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.
  • Cerebral aneurysm NOS
  • Cerebral arteriovenous fistula, acquired
  • Internal carotid artery aneurysm, intracranial portion
  • Internal carotid artery aneurysm, NOS

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.
  • congenital cerebral aneurysm, nonruptured Q28
  • ruptured cerebral aneurysm I60.7

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Convert I67.1 to ICD-9-CM

  • ICD-9-CM Code: 437.3 - Nonrupt cerebral aneurym
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Brain Aneurysm

A brain aneurysm is an abnormal bulge or "ballooning" in the wall of an artery in the brain. They are sometimes called berry aneurysms because they are often the size of a small berry. Most brain aneurysms produce no symptoms until they become large, begin to leak blood, or burst.

If a brain aneurysm presses on nerves in your brain, it can cause signs and symptoms. These can include:

  • A droopy eyelid
  • Double vision or other changes in vision
  • Pain above or behind the eye
  • A dilated pupil
  • Numbness or weakness on one side of the face or body

Treatment depends on the size and location of the aneurysm, whether it is infected, and whether it has burst. If a brain aneurysm bursts, symptoms can include a sudden, severe headache, nausea and vomiting, stiff neck, loss of consciousness, and signs of a stroke. Any of these symptoms requires immediate medical attention.
