Unspecified corneal scar and opacity H17. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
A corneal scar is either opacity or irregularity in the cornea that can limit the cornea's ability to accurately focus light. Not all scars affect vision.
Corneal opacity occurs when the cornea becomes scarred. This stops light from passing through the cornea to the retina and may cause the cornea to appear white or clouded over. Common causes include Infection, injury, corneal abrasion or scratch or swelling of the eye.
2022 ICD-10-CM Diagnosis Code H53. 132: Sudden visual loss, left eye.
A pterygium (pronounced “tehr-RIDGE-ium”) is a growth of scar tissue and blood vessels on the surface of the eye, known as the cornea. Normally, the outer surface of the eye is clear and smooth.
Although it is very difficult to see a corneal abrasion with the naked eye, you have to be suspicious of this if you have experienced any of the causes of trauma mentioned above.
The cornea is resilient and can typically heal from minor abrasions. However, major corneal damage can result in a corneal scar. These scars can be caused by improper use of contact lenses, deep scratches, lacerations, burns, and some diseases like shingles and syphilis.
Debris and/or chemicals entering the eye, infection, inflammation and diseases of the cornea can all lead to permanent scarring. Scar tissue formation often changes the optical properties of the cornea, thus altering sight.
