ICD-10 Code H52.223 – Regular astigmatism, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H52.223 – Regular astigmatism, bilateral
What it is
H52.223 identifies regular astigmatism affecting both eyes. It means the cornea or lens has a consistent, meridian-based curvature difference that causes blurred or distorted vision.
Clinical signs
Common findings include reduced visual clarity at distance or near, ghosting, and eye strain. Refraction typically shows a regular cylindrical error in both eyes; clinical features vary, refer to documentation.
When to use this code
Use this code when the record documents bilateral regular astigmatism, whether diagnosed during a routine eye exam or follow-up refractive evaluation. It fits cases where the provider specifically identifies astigmatism in both eyes and does not describe it as irregular.
If the note only mentions blurred vision without a refractive diagnosis, do not assume H52.223. Code the condition only when the documentation supports bilateral regular astigmatism.
Do not use for
Do not use this code for irregular astigmatism, unspecified astigmatism, or unilateral disease. Check documentation if the provider does not clearly state that both eyes are affected.
Coding tip
Confirm laterality and the word “regular” in the assessment before assigning H52.223.
