Specific Coding for Keratitis
Non-specific codes like H16 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for keratitis:
- CORNEAL ULCER-. loss of epithelial tissue from the surface of the cornea due to progressive erosion and necrosis of the tissue; usually caused by bacterial fungal or viral infection.
- KERATITIS-. inflammation of the cornea.
- KERATITIS DENDRITIC-. a form of herpetic keratitis characterized by the formation of small vesicles which break down and coalesce to form recurring dendritic ulcers characteristically irregular linear branching and ending in knoblike extremities. dictionary of visual science 3d ed
- ACANTHAMOEBA KERATITIS-. infection of the cornea by an ameboid protozoan which may cause corneal ulceration leading to blindness.
- KERATITIS HERPETIC-. a superficial epithelial herpesvirus hominis infection of the cornea characterized by the presence of small vesicles which may break down and coalesce to form dendritic ulcers keratitis dendritic. dictionary of visual science 3d ed
Information for Patients
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
- 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.
