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 2026, 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.
Aphakia, Postcataract
Absence of the crystalline lens resulting from cataract extraction.
About the H27 Code Range
The ICD-10 code section H27 covers various other disorders of the eye lens, including conditions such as aphakia (absence of the lens), lens dislocation, and other specified lens disorders. These codes help specify the precise nature and location of lens abnormalities, which are crucial for proper diagnosis and treatment.
This section includes codes for aphakia, like H27.0 for unspecified eye, and more specific codes such as H27.01 and H27.02 for aphakia of the right and left eyes respectively. Aphakia is sometimes referred to as "acquired aphakia," "traumatic aphakia," or linked to "aphakic glaucoma," and these synonyms assist coders in selecting the correct code. Dislocation of the lens is classified under H27.1, with subcodes distinguishing between subluxation (partial dislocation) and anterior or posterior dislocation by eye laterality. The codes also account for various other lens issues like thickening of the lens capsule or lens particle glaucoma (H27.8), and unspecified lens disorders under H27.9. Using these codes accurately ensures clear documentation of specific lens disorders such as "phacolytic glaucoma" or "phacomorphic angle closure glaucoma," which are important for precise clinical and billing records.
