Other disorders of conjunctiva (H11) ICD-10-CM
The H11 code range covers other disorders of conjunctiva with 124 ICD-10-CM diagnosis codes. 95 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 H11 range.
Pinguecula
A yellowish thickened lesion on the conjunctiva near the CORNEA representing a benign degenerative change in the CONJUNCTIVA caused by the leakage and deposition of certain blood proteins through the permeable capillaries near the LIMBUS.
Pterygium
An abnormal triangular fold of membrane in the interpalpebral fissure, extending from the conjunctiva to the cornea, being immovably united to the cornea at its apex, firmly attached to the sclera throughout its middle portion, and merged with the conjunctiva at its base. (Dorland, 27th ed)
About the H11 Code Range
The ICD-10 code section H11 covers various other disorders of the conjunctiva, the clear tissue covering the white part of the eye and inside of the eyelids. These codes help identify specific conditions affecting the conjunctiva, such as different types of pterygium, conjunctival degenerations, pigmentations, cysts, scars, hemorrhages, and vascular abnormalities.
This section includes codes like H11.0 for pterygium of the eye, which is a growth of tissue on the conjunctiva often seen as "pterygium of right eye" (H11.001) or "bilateral" involvement (H11.003). It also includes H11.1 for conjunctival degenerations and deposits, covering terms like "bulbar conjunctival degeneration" and "spheroidal degeneration of conjunctiva." Conditions such as pinguecula, conjunctival hemorrhage (also known as subconjunctival hemorrhage or hyposphagma), and conjunctival cysts are coded respectively under these headings. Notably, H11.8 addresses other specified disorders including pseudopterygium and conjunctivochalasis. By using these codes, medical coders and providers can accurately classify various conjunctival conditions, aiding in diagnosis and treatment planning related to conjunctival health.
