ICD-10 Code H52 – Disorders of refraction and accommodation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52 – Disorders of refraction and accommodation
What it is
H52 covers disorders where the eye cannot focus light properly or adjust focus normally. This includes common refractive problems and accommodation issues that affect clear vision.
Clinical signs
Patients may report blurred vision, eye strain, headaches, or difficulty seeing near or far objects. Clinical features vary; refer to documentation.
When to use this code
Use H52 when the record documents a refractive or accommodation disorder as the reason for the visit or as an established diagnosis. It is appropriate for routine vision complaints, eye exams, or follow-up care when the specific type is not coded more precisely. Check documentation if the provider names a more specific H52 subcode.
Do not use for
Do not use H52 for eye disease, injury, or neurologic vision loss that is not a refraction or accommodation problem. Do not use it when the chart supports a more specific diagnosis elsewhere.
Coding tip
Review the provider’s exact wording and choose the most specific H52 code supported by the note.
