ICD-10 Code H52.539 – Spasm of accommodation, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.539 – Spasm of accommodation, unspecified eye
What it is
H52.539 identifies a spasm of accommodation affecting an unspecified eye. It refers to involuntary, sustained focusing effort of the ciliary muscle that can make distance vision temporarily blurred.
Clinical signs
Patients may report intermittent blurred distance vision, eye strain, headaches, or difficulty relaxing focus after near work. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents spasm of accommodation and does not specify the right or left eye. It is appropriate when the record describes accommodative spasm, ciliary spasm, or similar wording without laterality. Do not infer laterality from the exam unless documented.
Do not use for
Do not use this code for refractive error, presbyopia, or general eye strain without documented accommodative spasm. If the chart specifies a right or left eye, use the laterality-specific code instead.
Coding tip
Check the ophthalmology note for laterality and exact terminology before assigning H52.539.
