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 2024 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 Corneal pigmentations and deposits

Non-specific codes like H18.0 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for corneal pigmentations and deposits:

  • H18.00 for Unspecified corneal deposit - NON-BILLABLE CODE

  • Use H18.001 for Unspecified corneal deposit, right eye - BILLABLE CODE

  • Use H18.002 for Unspecified corneal deposit, left eye - BILLABLE CODE

  • Use H18.003 for Unspecified corneal deposit, bilateral - BILLABLE CODE

  • Use H18.009 for Unspecified corneal deposit, unspecified eye - BILLABLE CODE

  • H18.01 for Anterior corneal pigmentations - NON-BILLABLE CODE

  • Use H18.011 for Anterior corneal pigmentations, right eye - BILLABLE CODE

  • Use H18.012 for Anterior corneal pigmentations, left eye - BILLABLE CODE

  • Use H18.013 for Anterior corneal pigmentations, bilateral - BILLABLE CODE

  • Use H18.019 for Anterior corneal pigmentations, unspecified eye - BILLABLE CODE

  • H18.02 for Argentous corneal deposits - NON-BILLABLE CODE

  • Use H18.021 for Argentous corneal deposits, right eye - BILLABLE CODE

  • Use H18.022 for Argentous corneal deposits, left eye - BILLABLE CODE

  • Use H18.023 for Argentous corneal deposits, bilateral - BILLABLE CODE

Patient Education


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:

  • Refractive errors
  • Allergies
  • Infections
  • Injuries
  • Dystrophies - conditions in which parts of the cornea lose clarity due to a buildup of cloudy material

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