About H11.13

H11.13 is the ICD-10-CM diagnosis code for conjunctival pigmentations. It belongs to category H11 (other disorders of conjunctiva), block H10-H11 (disorders of conjunctiva) 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 H11.1 (conjunctival degenerations and deposits), H11.13 is specifically for conjunctival pigmentations. Related codes cover unspecified conjunctival degenerations (H11.10), conjunctival deposits (H11.11), conjunctival concretions (H11.12), conjunctival xerosis, unspecified (H11.14) and Pinguecula (H11.15).

To report this condition, pick the subcode that matches the documentation: H11.131 (right eye), H11.132 (left eye), H11.133 (bilateral) and H11.139 (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.
