2022 ICD-10-CM Code H18.0

Corneal pigmentations and deposits

Version 2021

Not Valid for Submission

ICD-10:H18.0
Short Description:Corneal pigmentations and deposits
Long Description:Corneal pigmentations and deposits

Code Classification

  • Diseases of the eye and adnexa (H00–H59)
    • Disorders of sclera, cornea, iris and ciliary body (H15-H22)
      • Other disorders of cornea (H18)

H18.0 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of corneal pigmentations and deposits. The code is not specific and is NOT valid for the year 2022 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.

Information for Patients


Corneal Disorders

Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust, and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas.

Problems with the cornea include

Treatments of corneal disorders include medicines, corneal transplantation, and corneal laser surgery.
