Code Classification

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

H34.9 is a billable diagnosis code used to specify a medical diagnosis of unspecified retinal vascular occlusion. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like H34.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

    sudden ischemia in the retina due to blocked blood flow through the central retinal artery or its branches leading to sudden complete or partial loss of vision, respectively, in the eye.
  • Retinal Vascular Occlusion

    an occlusion of the retinal vasculature.
  • Central Retinal Artery Occlusion, Bilateral|Central retinal artery occlusion, bilateral

    evidence of central retinal artery occlusion that is bilateral.
  • Central Retinal Artery Occlusion, Left Eye|Central retinal artery occlusion, left eye

    evidence of central retinal artery occlusion in the left eye.
  • Central Retinal Artery Occlusion, Right Eye|Central retinal artery occlusion, right eye

    evidence of central retinal artery occlusion in the right eye.
  • Central Retinal Artery Occlusion|Central Retinal Arterial Occlusion|Central retinal artery occlusion, unspecified eye

    blockage of the central retinal artery.

    evidence of partial retinal artery occlusion that is bilateral.
  • Partial Retinal Artery Occlusion, Left Eye|Partial retinal artery occlusion, left eye

    evidence of partial retinal artery occlusion in the left eye.
  • Partial Retinal Artery Occlusion, Right Eye|Partial retinal artery occlusion, right eye

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

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
