ICD-10-CM Code:
H52
ICD-10 Code for:
Disorders of refraction and accommodation
Is Billable?
Not Valid for Submission
Code Navigator:

H52 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity from the list below for a diagnosis of disorders of refraction and accommodation. The code is not specific and is NOT valid for the year 2026 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Disorders of refraction and accommodation

Non-specific codes like H52 require more digits to indicate the appropriate level of specificity. Consider using any of the following billable codes with a higher level of specificity when coding for disorders of refraction and accommodation:

  • 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

Code Classification

  • Diseases of the eye and adnexa
    H00–H59
    • Disorders of ocular muscles, binocular movement, accommodation and refraction
      H49-H52
      • Disorders of refraction and accommodation

Patient Education


Refractive Errors

The cornea and lens of your eye helps you focus. Refractive errors are vision problems that happen when the shape of the eye keeps you from focusing well. The cause could be the length of the eyeball (longer or shorter), changes in the shape of the cornea, or aging of the lens.

Four common refractive errors are:

  • Myopia, or nearsightedness - clear vision close up but blurry in the distance
  • Hyperopia, or farsightedness - clear vision in the distance but blurry close up
  • Presbyopia - inability to focus close up as a result of aging
  • Astigmatism - focus problems caused by the cornea

The most common symptom is blurred vision. Other symptoms may include double vision, haziness, glare or halos around bright lights, squinting, headaches, or eye strain.

Glasses or contact lenses can usually correct refractive errors. Laser eye surgery may also be a possibility.
