About H18.06
H18.06 is the ICD-10-CM diagnosis code for stromal corneal pigmentations. 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 H18.0 (corneal pigmentations and deposits), H18.06 is specifically for stromal corneal pigmentations. Related codes cover unspecified corneal deposit (H18.00), anterior corneal pigmentations (H18.01), Argentous corneal deposits (H18.02), corneal deposits in metabolic disorders (H18.03), Kayser-Fleischer ring (H18.04) and posterior corneal pigmentations (H18.05).
To report this condition, pick the subcode that matches the documentation: H18.061 (right eye), H18.062 (left eye), H18.063 (bilateral) and H18.069 (unspecified eye).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
