Other disorders of lens (H27) ICD-10-CM
The H27 code range covers other disorders of lens with 25 ICD-10-CM diagnosis codes. 19 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the H27 range.
Aphakia
Absence of crystalline lens totally or partially from field of vision, from any cause except after cataract extraction. Aphakia is mainly congenital or as result of LENS DISLOCATION AND SUBLUXATION.
About the H27 Code Range
A lens that has moved out of place falls under dislocation. Aphakia and other lens disorders have separate branches.
H27.0 groups aphakia by right eye, left eye, both eyes, or unspecified eye. H27.1 separates unspecified dislocation, subluxation, anterior dislocation, and posterior dislocation. Subluxation and the anterior and posterior groups also distinguish the affected eye. H27.8 identifies other specified lens disorders, while H27.9 identifies an unspecified lens disorder.
