ICD-10 Code H52.522 – Paresis of accommodation, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.522 – Paresis of accommodation, left eye
What it is
This code identifies weakened accommodative function in the left eye. The eye has reduced ability to focus on near objects, often causing blurred near vision.
Clinical signs
Clinical features may include difficulty shifting focus to near tasks, eye strain, or blurred reading vision. Findings should support impaired accommodation in the left eye; refer to documentation if details are limited.
When to use this code
Use H52.522 when the provider documents paresis of accommodation specifically affecting the left eye. It is appropriate when the condition is diagnosed as a distinct refractive or focusing problem, not just general blurred vision. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for unspecified accommodation problems or bilateral involvement unless documented that way. Do not use it when the record only mentions refractive error, presbyopia, or nonspecific visual complaints.
Coding tip
Verify laterality in the assessment and avoid defaulting to H52.52 when the left eye is explicitly stated.
