ICD-10 Code H53.5 – Color vision deficiencies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.5 – Color vision deficiencies
What it is
H53.5 identifies reduced or absent ability to distinguish colors. It covers color vision deficiency, whether inherited or acquired, when documented as the reason for the encounter.
Clinical signs
Patients may report trouble telling red from green, blue from yellow, or other color differences. Clinical features vary; refer to documentation, and use test results only when they are part of the record.
When to use this code
Use H53.5 when the clinician documents color vision deficiency, color blindness, or a similar diagnosis. It is appropriate for evaluation, screening follow-up, or problem-list documentation when the condition is confirmed. If the note only says “vision problem,” check documentation before assigning this code.
Do not use for
Do not use this code for general blurred vision, refractive error, or other unspecified eye complaints. If the record does not clearly identify a color vision defect, check documentation.
Coding tip
Code H53.5 only when the chart explicitly states color vision deficiency, and capture any documented cause if the provider identifies one.
