H36 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 disorders in diseases classified elsewhere. The code is not specific and is NOT valid for the year 2025 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 disorders in diseases classified elsewhere

Non-specific codes like H36 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 disorders in diseases classified elsewhere:

  • H36.8 for Other retinal disorders in diseases classified elsewhere - NON-BILLABLE CODE

  • H36.81 for Nonproliferative sickle-cell retinopathy - NON-BILLABLE CODE

  • H36.82 for Proliferative sickle-cell retinopathy - NON-BILLABLE CODE

  • Use H36.89 for Other retinal disorders in diseases classified elsewhere - BILLABLE CODE

Code Classification

  • Diseases of the eye and adnexa
    H00–H59
    • Disorders of choroid and retina
      H30-H36
      • Retinal disorders in diseases classified elsewhere
        H36

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Retinal and vitreous conditions

CCSR Code: EYE005

Inpatient Default: X - Not applicable.

Outpatient Default: X - Not applicable.

Convert H36 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Ret dystrph in lipidoses

ICD-9-CM: 362.71

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.

Ret dystrph in syst dis

ICD-9-CM: 362.72

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.

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.
