ICD-10 Code H53.59 – Other color vision deficiencies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.59 – Other color vision deficiencies
What it is
H53.59 identifies color vision problems that do not fit a more specific inherited or acquired color vision diagnosis. Use it when the record states abnormal color perception, but the exact type is not documented.
Clinical signs
Patients may report trouble distinguishing certain colors, especially in routine testing or daily tasks. Clinical features vary; refer to documentation, and note whether the deficit is congenital or acquired if stated.
When to use this code
Use this code when the provider documents “other color vision deficiency,” “color blindness,” or a similar nonspecific color discrimination problem. It is appropriate when the chart does not specify a classic red-green or blue-yellow pattern. Check documentation if the cause, laterality, or exact defect is unclear.
Do not use for
Do not use H53.59 when the record clearly identifies a more specific color vision disorder. Do not assign it for general visual loss, refractive error, or unconfirmed screening results without a documented diagnosis.
Coding tip
If the note only says “abnormal color vision,” code the documented term and query for specificity when needed.
