About H11
H11 is the ICD-10-CM diagnosis code for other disorders of conjunctiva. It belongs to 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 7 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: H11.0 (eye), H11.1 (deposits), H11.2 (scars), H11.3 (hemorrhage), H11.4 (cysts), H11.8 (conjunctiva) and H11.9 (conjunctiva).
Don't report H11 together with the conditions in its Excludes1 note: keratoconjunctivitis (H16.2-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
