About H27.12
H27.12 is the ICD-10-CM diagnosis code for anterior dislocation of lens. It belongs to category H27 (other disorders of lens), block H25-H28 (disorders of lens) 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 H27.1 (dislocation of lens), H27.12 is specifically for anterior dislocation of lens. Related codes cover unspecified dislocation of lens (H27.10), subluxation of lens (H27.11) and posterior dislocation of lens (H27.13).
To report this condition, pick the subcode that matches the documentation: H27.121 (right eye), H27.122 (left eye), H27.123 (bilateral) and H27.129 (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.
