ICD-10 Code H52.6 – Other disorders of refraction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.6 – Other disorders of refraction
What it is
H52.6 identifies refractive problems that do not fit the more specific categories of myopia, hypermetropia, astigmatism, or presbyopia. Use it when documentation states another refraction disorder and the exact type is not specified.
Clinical signs
Patients may report blurred vision, eye strain, or difficulty focusing at certain distances. Clinical features vary; refer to documentation and the eye examination findings supporting a refractive diagnosis.
When to use this code
Use H52.6 when the provider documents an unspecified or other refractive disorder after evaluation. It may apply when the chart notes an abnormal refraction that is not named in a more specific ICD-10-CM category. Check documentation if the record also mentions a separate ocular disease.
Do not use for
Do not use this code for routine refractive errors that are specifically documented as myopia, hypermetropia, astigmatism, or presbyopia. Do not assign it when the diagnosis is better explained by another eye condition.
Coding tip
Code the most specific refractive diagnosis available, and use H52.6 only when the provider’s wording does not support a more precise code.
