ICD-10 Code H52.53 – Spasm of accommodation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.53 – Spasm of accommodation
What it is
H52.53 identifies spasm of accommodation, an involuntary, sustained contraction of the ciliary muscle. It can cause the eye to focus as if for near vision even when distance viewing is intended.
Clinical signs
Common findings include blurred distance vision, variable refraction, eye strain, and intermittent headaches. Clinical features vary; refer to documentation.
When to use this code
Use H52.53 when the clinician documents accommodative spasm or ciliary spasm as the diagnosed cause of visual symptoms. It may also fit records describing pseudomyopia or fluctuating refraction when the provider links them to spasm of accommodation. Check documentation if the note only mentions nonspecific vision complaints.
Do not use for
Do not use this code for ordinary refractive error, presbyopia, or unspecified blurred vision without documented accommodative spasm. If the record does not clearly support the diagnosis, check documentation.
Coding tip
Assign H52.53 only when the provider explicitly identifies spasm of accommodation or a clearly equivalent term.
