ICD-10 Code H52.529 – Paresis of accommodation, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.529 – Paresis of accommodation, unspecified eye
What it is
H52.529 identifies weakened accommodation in an unspecified eye. This means the eye has reduced ability to focus on near objects, but the exact cause or laterality is not further specified.
Clinical signs
Clinical features vary; refer to documentation. Common findings include blurred near vision, eye strain, and difficulty shifting focus from distance to near tasks.
When to use this code
Use this code when the provider documents paresis of accommodation and does not specify the right or left eye. It may be used when the record notes reduced accommodative function without a more specific diagnosis. Check documentation if another refractive or neurologic condition better explains the finding.
Do not use for
Do not use this code for simple refractive error, presbyopia, or other clearly documented causes of near-vision difficulty. If the eye or cause is specified differently, code that condition instead.
Coding tip
Verify laterality and the exact provider wording before assigning H52.529.
