About H27.1

H27.1 is the ICD-10-CM diagnosis code for 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 (other disorders of lens), H27.1 is specifically for dislocation of lens. Related codes cover aphakia (H27.0), other specified disorders of lens (H27.8) and unspecified disorder of lens (H27.9).

To report this condition, pick the subcode that matches the documentation: H27.10 (lens), H27.11 (lens), H27.12 (lens) and H27.13 (lens).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
