ICD-10 Code H52.13 – Myopia, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.13 – Myopia, bilateral
What it is
H52.13 identifies myopia in both eyes, also called nearsightedness. It means distant objects are seen more clearly than near objects because light focuses in front of the retina.
Clinical signs
Common findings include blurred distance vision, squinting, and difficulty seeing road signs or classroom boards. Refraction typically shows a myopic error in each eye; clinical features vary, so refer to documentation.
When to use this code
Use H52.13 when the provider documents bilateral myopia or nearsightedness affecting both eyes. It also fits routine eye exams when refractive error is confirmed and no more specific eye disorder explains the vision problem.
If the record only states decreased vision without a refractive diagnosis, check documentation before assigning this code. You should code the documented condition, not presumed visual complaints.
Do not use for
Do not use this code for unilateral myopia, unspecified refractive error, or vision loss caused by cataract, corneal disease, or retinal disorders. Check documentation.
Coding tip
Assign H52.13 only when the chart clearly documents myopia in both eyes; otherwise, verify laterality and specificity first.
