ICD-10 Code H52.533 – Spasm of accommodation, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.533 – Spasm of accommodation, bilateral
What it is
H52.533 identifies a bilateral spasm of accommodation, meaning both eyes are over-focusing involuntarily. It is used when the record shows accommodative spasm rather than a general refractive error.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include intermittent blurred distance vision, variable refraction, and difficulty relaxing focus after near work.
When to use this code
Use this code when the clinician documents spasm of accommodation in both eyes, or equivalent wording such as bilateral accommodative spasm. It may appear in ophthalmology or optometry notes with symptoms tied to focusing difficulty. Check documentation if laterality is unclear.
Do not use for
Do not use this code for unspecified refractive error, simple eyestrain, or other accommodative disorders without spasm. If the note does not confirm bilateral involvement, check documentation before coding.
Coding tip
Verify both the diagnosis and laterality in the provider note before assigning H52.533.
