H52 is a non-billable ICD-10-CM category code for disorders of refraction and accommodation, so it cannot be submitted on claims. Use a more specific code from this category instead, such as H52.00, H52.01, H52.02, and H52.03.

  • H52.0 for Hypermetropia

  • Use H52.00 for Hypermetropia, unspecified eye

  • Use H52.01 for Hypermetropia, right eye

  • Use H52.02 for Hypermetropia, left eye

  • Use H52.03 for Hypermetropia, bilateral

  • H52.1 for Myopia

  • Use H52.10 for Myopia, unspecified eye

  • Use H52.11 for Myopia, right eye

  • Use H52.12 for Myopia, left eye

  • Use H52.13 for Myopia, bilateral

  • H52.2 for Astigmatism

  • H52.20 for Unspecified astigmatism

  • H52.21 for Irregular astigmatism

  • H52.22 for Regular astigmatism

  • H52.3 for Anisometropia and aniseikonia

  • Use H52.31 for Anisometropia

  • Use H52.32 for Aniseikonia

  • Use H52.4 for Presbyopia

  • H52.5 for Disorders of accommodation

  • H52.51 for Internal ophthalmoplegia (complete) (total)

  • H52.52 for Paresis of accommodation

  • H52.53 for Spasm of accommodation

  • Use H52.6 for Other disorders of refraction

  • Use H52.7 for Unspecified disorder of refraction

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to H52: its own notes plus those printed at block H49-H52 and Chapter 7. A note printed at a category, block or chapter applies to every code under it.

Excludes2

Patient EducationClinical

Refractive Errors

The cornea and lens of your eye bend (refract) light rays to focus them on the retina. Refractive errors happen when the shape of your eye prevents light from focusing correctly on the retina. This causes blurry vision. Changes in the eye's shape affect how light rays bend and focus, leading to vision problems.

Questions About H52Overview

What is the ICD-10 code for disorders of refraction and accommodation?

H52 is the ICD-10-CM category for disorders of refraction and accommodation, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is H52 (Disorders of refraction and accommodation) a billable code?

No. This is a category header that groups the codes for disorders of refraction and accommodation, and headers cannot be submitted on claims. Claims for disorders of refraction and accommodation need a more specific code from this category, such as H52.00, H52.01, and H52.02.
