ICD-10 Code H52.1 – Myopia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.1 – Myopia
What it is
Myopia is nearsightedness: distant objects look blurred because light focuses in front of the retina. You use this code for documented refractive error affecting distance vision.
Clinical signs
Typical findings include reduced distance visual acuity with relatively better near vision. Patients may squint, hold objects closer, or report trouble seeing signs; clinical features vary, refer to documentation.
When to use this code
Use H52.1 when the record specifically states myopia, nearsightedness, or refractive error consistent with myopia. It is appropriate for routine eye exams, vision complaints, or follow-up visits when the diagnosis is confirmed.
Code the documented condition as written, and verify whether the note identifies unilateral, bilateral, or unspecified myopia. If the clinician documents another refractive disorder or a disease causing blurred vision, check documentation before assigning H52.1.
Do not use for
Do not use H52.1 for blurred vision without a diagnosis of myopia. Do not use it when the problem is due to cataract, corneal disease, or another eye disorder.
Coding tip
Match the code to the provider’s explicit diagnosis, not the patient’s complaint of poor distance vision.
