Code Classification

  • Diseases of the circulatory system
    (I00–I99)

      (I60-I69)
      • Occlusion and stenosis of precerebral arteries, not resulting in cerebral infarction
        (I65)

I65 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of occlusion and stenosis of precerebral arteries, not resulting in cerebral infarction. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Occls and stenosis of precerb art, not rslt in cereb infrc

Non-specific codes like I65 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for occls and stenosis of precerb art, not rslt in cereb infrc:

  • I65.0 for Occlusion and stenosis of vertebral artery - NON-BILLABLE CODE

  • Use I65.01 for Occlusion and stenosis of right vertebral artery - BILLABLE CODE

  • Use I65.02 for Occlusion and stenosis of left vertebral artery - BILLABLE CODE

  • Use I65.03 for Occlusion and stenosis of bilateral vertebral arteries - BILLABLE CODE

  • Use I65.09 for Occlusion and stenosis of unspecified vertebral artery - BILLABLE CODE

  • Use I65.1 for Occlusion and stenosis of basilar artery - BILLABLE CODE

  • I65.2 for Occlusion and stenosis of carotid artery - NON-BILLABLE CODE

  • Use I65.21 for Occlusion and stenosis of right carotid artery - BILLABLE CODE

  • Use I65.22 for Occlusion and stenosis of left carotid artery - BILLABLE CODE

  • Use I65.23 for Occlusion and stenosis of bilateral carotid arteries - BILLABLE CODE

  • Use I65.29 for Occlusion and stenosis of unspecified carotid artery - BILLABLE CODE

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.


Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
  • embolism of precerebral artery
  • narrowing of precerebral artery
  • obstruction (complete) (partial) of precerebral artery
  • thrombosis of precerebral artery

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.
  • insufficiency, NOS, of precerebral artery G45
  • insufficiency of precerebral arteries causing cerebral infarction I63.0 I63.2
