ICD-10 Code H52.52 – Paresis of accommodation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.52 – Paresis of accommodation
What it is
H52.52 identifies weakness of the eye’s focusing mechanism, so the lens does not adjust normally for near vision. It is a refractive/accommodative problem, not a disease of the retina or optic nerve.
Clinical signs
Typical findings include blurred near vision, difficulty sustaining close work, and reduced ability to shift focus from distance to near. Clinical features vary; refer to documentation.
When to use this code
Use H52.52 when the provider documents paresis of accommodation, accommodative weakness, or similar wording tied to impaired focusing. It may be used after an eye exam when the diagnosis is clearly stated. Check documentation if the record only mentions nonspecific visual complaints.
Do not use for
Do not use this code for simple refractive error, presbyopia, or unspecified blurred vision without documented accommodative paresis. Do not assign it when the chart does not support a specific focusing disorder.
Coding tip
Code only when the provider explicitly links the symptoms to paresis of accommodation.
