A 'billable code' is detailed enough to be used to specify a medical diagnosis. Keratoconus (KC, KTCN) is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than the more normal gradual curve.

What causes keratoconus? Although keratoconus has been studied for decades, it remains poorly understood. The definitive cause of keratoconus is unknown, though it is believed that the predisposition to develop the disease is present at birth. A common finding in keratoconus is the loss of collagen in the cornea.
In general terms, a topographic keratoconus suspect will have a localised area of abnormal steepening which is often inferior, but can be central, or, rarely, superior, and may present as an asymmetrical, truncated or skewed-axis bowtie. The different configurations seen with keratoconus are shown in fig 1.
Dry eye syndrome of bilateral lacrimal glands H04. 123 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM H04. 123 became effective on October 1, 2021.

Corneal scarring refers to the scarring of the cornea, from trauma, or infection or disease, which results in impaired vision, or even blindness, in the affected eye.
Keratoconus (KC, KTCN) is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than the more normal gradual curve. Keratoconus can cause substantial distortion of vision, with multiple images, streaking and sensitivity to light all often reported by the person.
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code H18.622 and a single ICD9 code, 371.62 is an approximate match for comparison and conversion purposes.
