ICD-10 Code H53.53 – Deuteranomaly (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.53 – Deuteranomaly
What it is
Deuteranomaly is a type of red-green color vision deficiency caused by altered perception of green wavelengths. You use this code when documentation specifically identifies deuteranomaly rather than a general color blindness diagnosis.
Clinical signs
Patients may have difficulty distinguishing reds, greens, and some browns, especially on color vision testing. Clinical features vary; refer to documentation.
When to use this code
Use H53.53 when the provider documents deuteranomaly, including after formal eye examination or color vision screening. It also fits when the record clearly states congenital or acquired deuteranomaly. Do not code from suspicion alone; check documentation.
Do not use for
Do not use this code for unspecified visual disturbance, other color vision defects, or normal screening results. If the chart only says color blindness without subtype, check documentation.
Coding tip
Code the exact documented subtype; if the note does not name deuteranomaly, query or code the more general diagnosis only when supported.
