About H01.02
H01.02 is the ICD-10-CM diagnosis code for squamous blepharitis. It belongs to category H01 (other inflammation of eyelid), block H00-H05 (disorders of eyelid, lacrimal system and orbit) 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 9 subcodes must be used instead.
Within H01.0 (blepharitis), H01.02 is specifically for squamous blepharitis. Related codes cover unspecified blepharitis (H01.00) and ulcerative blepharitis (H01.01).
To report this condition, pick the subcode that matches the documentation: H01.021 (right upper eyelid), H01.022 (right lower eyelid), H01.023 (right eye, unspecified eyelid), H01.024 (left upper eyelid), H01.025 (left lower eyelid), H01.026 (left eye, unspecified eyelid), H01.029 (unspecified eye, unspecified eyelid), H01.02A (right eye, upper and lower eyelids) and 1 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
