Code Classification

  • Diseases of the eye and adnexa
    (H00–H59)
    • Disorders of choroid and retina
      (H30-H36)
      • Retinal vascular occlusions
        (H34)

H34 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of retinal vascular occlusions. 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 Retinal vascular occlusions

Non-specific codes like H34 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 retinal vascular occlusions:

  • H34.0 for Transient retinal artery occlusion - NON-BILLABLE CODE

  • Use H34.00 for Transient retinal artery occlusion, unspecified eye - BILLABLE CODE

  • Use H34.01 for Transient retinal artery occlusion, right eye - BILLABLE CODE

  • Use H34.02 for Transient retinal artery occlusion, left eye - BILLABLE CODE

  • Use H34.03 for Transient retinal artery occlusion, bilateral - BILLABLE CODE

  • H34.1 for Central retinal artery occlusion - NON-BILLABLE CODE

  • Use H34.10 for Central retinal artery occlusion, unspecified eye - BILLABLE CODE

  • Use H34.11 for Central retinal artery occlusion, right eye - BILLABLE CODE

  • Use H34.12 for Central retinal artery occlusion, left eye - BILLABLE CODE

  • Use H34.13 for Central retinal artery occlusion, bilateral - BILLABLE CODE

  • H34.2 for Other retinal artery occlusions - NON-BILLABLE CODE

  • H34.21 for Partial retinal artery occlusion - NON-BILLABLE CODE

  • H34.23 for Retinal artery branch occlusion - NON-BILLABLE CODE

  • H34.8 for Other retinal vascular occlusions - NON-BILLABLE CODE

  • H34.81 for Central retinal vein occlusion - NON-BILLABLE CODE

  • H34.82 for Venous engorgement - NON-BILLABLE CODE

  • H34.83 for Tributary (branch) retinal vein occlusion - NON-BILLABLE CODE

  • Use H34.9 for Unspecified retinal vascular occlusion - 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.


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.

Patient Education


Retinal Disorders

The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. In the center of this nerve tissue is the macula. It provides the sharp, central vision needed for reading, driving and seeing fine detail.

Retinal disorders affect this vital tissue. They can affect your vision, and some can be serious enough to cause blindness. Examples are:

  • Macular degeneration - a disease that destroys your sharp, central vision
  • Diabetic eye disease
  • Retinal detachment - a medical emergency, when the retina is pulled away from the back of the eye
  • Retinoblastoma - cancer of the retina. It is most common in young children.
  • Macular pucker - scar tissue on the macula
  • Macular hole - a small break in the macula that usually happens to people over 60
  • Floaters - cobwebs or specks in your field of vision
