Code Classification

  • Diseases of the eye and adnexa
    • Disorders of choroid and retina
      • Other retinal disorders

H35.059 is a billable diagnosis code used to specify a medical diagnosis of retinal neovascularization, unspecified, unspecified eye. 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 H35.059 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.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Choroidal retinal neovascularization
  • Classic choroidal neovascular membrane
  • Extrafoveal choroidal neovascularization
  • Extramacular choroidal neovascular membrane
  • Idiopathic choroidal neovascular membrane
  • Juxtafoveal choroidal neovascularization
  • Occult choroidal neovascular membrane
  • Occult neovascularization of macula
  • Peripapillary choroidal neovascular membrane
  • Peripheral retinal neovascularization
  • Polypoidal choroidal vasculopathy
  • Retinal angiomatous proliferation
  • Retinal neovascularization
  • Retinal pigment epithelial detachment with vascularization

Clinical Classification

Clinical Information

  • Polypoidal Choroidal Vasculopathy

    a choroid neovascularization characterized by serosanguineous retinal pigment epithelial detachment and leakage of serous exudate sometimes associated with aneurysmal polypoidal lesions.
  • Retinal Neovascularization

    formation of new blood vessels originating from the retinal veins and extending along the inner (vitreal) surface of the retina.
  • Choroid

    the thin, highly vascular membrane covering most of the posterior of the eye between the retina and sclera.

Convert H35.059 to ICD-9-CM

  • ICD-9-CM Code: 362.16 - Retinal neovascular NOS
    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

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

[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.
