371.89 is a legacy non-billable code used to specify a medical diagnosis of other corneal disorders. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
When it comes to the cornea (with the exception of dystrophies), there are 3 ICD-10 codes for every ICD-9 code. You’ll find these codes in chapter 7 of ICD-10; look for the section titled Disorders of Sclera, Cornea, Iris, and Ciliary Body (H15-H22). Except for dystrophies, corneal ICD-10 codes have a digit for laterality: 3 for both eyes. Example.
The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
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.
Except for dystrophies, corneal ICD-10 codes have a digit for laterality:
In these examples, report laterality by replacing the dash with a 1, 2, or 3.
ICD-10’s section for hereditary corneal dystrophies lists 7 conditions. Each has only 1 code; no laterality is needed.
Excludes1 Notes flag conditions that can’t be billed in the same eye at the same patient encounter. For example, M35.01 Sjögren’s syndrome isn’t payable with H16.22 Keratoconjunctivitis sicca. Similarly, H1.21 Acute toxic conjunctivitis is not payable with T26- Burn and corrosion confined to eye and adnexa.
T15.0- Corneal foreign body, T15.1- Conjunctival foreign body, and T26.1- Burn of cornea and conjunctival sac must be submitted as 7-character codes, with the final character being an A (if an initial encounter), D (subsequent encounter), or S (sequela).
