H18.82Corneal disorder due to contact lens

H18.82 is the ICD-10-CM diagnosis code for corneal disorder due to contact lens. It belongs to category H18 (other disorders of cornea), block H15-H22 (disorders of sclera, cornea, iris and ciliary body) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within H18.8 (other specified disorders of cornea), H18.82 is specifically for corneal disorder due to contact lens. Related codes cover anesthesia and hypoesthesia of cornea (H18.81), recurrent erosion of cornea (H18.83) and other specified disorders of cornea (H18.89).

To report this condition, pick the subcode that matches the documentation: H18.821 (right eye), H18.822 (left eye), H18.823 (bilateral) and H18.829 (unspecified eye).

The conditions in its Excludes2 note aren't part of H18.82, but may be coded alongside it if the patient has both: corneal edema due to contact lens (H18.21-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
