Dry Eye Causes
Sometimes, there is a lack of balance in the tear system. Or, it could be that your heater, air conditioner, vacuum, or other environmental factors around you are drying out your tear film. Some other causes of dry eye include the following:
● The natural aging process, which is very common in menopause
● Medications such as antihistamines, SSRIs, and those for high blood pressure
● Diseases which affect your ability to make tears, such as Sjogren's syndrome, collagen vascular diseases, and rheumatoid arthritis
● Problems that do not allow your eyelids to close fully
ICD-10 Code For Dry Eyes
The two most frequently used diagnosis codes for dry eyes include: 375.15 - Tear film insufficiency, unspecified. This code should be used only after a series of tear volume tests, such as the phenol red thread or Schirmer’s, demonstrate low tear volume. Otherwise, 370.33 - Keratoconjunctivitis sicca, not specified as Sjogren’s can be used.
