ICD-10 Code H52.7 – Unspecified disorder of refraction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.7 – Unspecified disorder of refraction
What it is
H52.7 identifies a refractive problem of the eye when the exact type is not documented. Use it when the record shows a vision focusing disorder, but the specific refractive error is not stated.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart may note blurred vision, difficulty seeing clearly at distance or near, or need for corrective lenses without specifying myopia, hyperopia, astigmatism, or presbyopia.
When to use this code
Use this code when the clinician documents a refractive disorder but does not identify the exact diagnosis. It is also appropriate when the available note supports a refractive issue, yet the record is too limited for a more specific code. Check documentation before assigning a more detailed option.
Do not use for
Do not use H52.7 if the chart specifies a particular refractive error, such as myopia, hyperopia, astigmatism, or presbyopia. Also avoid it when the vision problem is due to another eye disorder rather than refraction.
Coding tip
If the provider names the refractive condition, code that specific diagnosis instead of this unspecified category.
