ICD-10 Code H53.50 – Unspecified color vision deficiencies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.50 – Unspecified color vision deficiencies
What it is
H53.50 identifies a documented color vision problem when the type is not further specified. Use it when the record states color blindness or color vision deficiency without naming a congenital or acquired subtype.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the patient has difficulty distinguishing certain colors or fails screening tests, but the chart does not define the exact pattern or cause.
When to use this code
Use this code when the clinician documents color vision deficiency, color blindness, or abnormal color perception and provides no more detail. It also fits when testing confirms a deficit but the subtype is not recorded. If the note identifies a specific inherited or acquired disorder, code that diagnosis instead.
Do not use for
Do not use H53.50 for a clearly documented specific color vision defect, such as a congenital red-green deficiency, if another code is available. Do not use it for general visual loss or nonspecific eye complaints.
Coding tip
Code the most specific color vision diagnosis documented; if the record is vague, H53.50 is the appropriate unspecified option.
