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)

H18.53 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of granular corneal dystrophy. 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 Granular corneal dystrophy

Non-specific codes like H18.53 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 granular corneal dystrophy:

  • Use H18.531 for Granular corneal dystrophy, right eye - BILLABLE CODE

  • Use H18.532 for Granular corneal dystrophy, left eye - BILLABLE CODE

  • Use H18.533 for Granular corneal dystrophy, bilateral - BILLABLE CODE

  • Use H18.539 for Granular corneal dystrophy, unspecified eye - BILLABLE CODE

Clinical Classification

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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
