Retinal detachments and breaks (H33) ICD-10-CM
The H33 code range covers retinal detachments and breaks with 85 ICD-10-CM diagnosis codes. 65 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 H33 range.
Retinal Detachment
Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery. (Dorland, 27th ed; Newell, Ophthalmology: Principles and Concepts, 7th ed, p310-12).
Retinoschisis
A vitreoretinal dystrophy characterized by splitting of the neuroretinal layers. It occurs in two forms: degenerative retinoschisis and X chromosome-linked juvenile retinoschisis.
About the H33 Code Range
ICD-10 codes H33 and its subcategories classify various types of retinal detachments and retinal breaks, crucial for identifying specific retinal conditions affecting one or both eyes. These codes cover a range of issues from retinal detachment with breaks to retinoschisis, retinal cysts, and serous retinal detachments.
The ICD-10 code for retinal detachment with retinal break (H33.0) includes specific laterality such as right (H33.001), left (H33.002), or bilateral eyes (H33.003). Medical coders can distinguish between single (H33.01) and multiple breaks (H33.02) or giant retinal tears (H33.03). Synonyms like "detachment of retina with break" or "rhegmatogenous retinal detachment" relate closely to these codes, aiding accurate code selection. Codes for retinoschisis and retinal cysts (H33.1) include different types, such as cysts of ora serrata and parasitic cysts, often linked with terms like "schisis of retina."
Serous retinal detachment (H33.2) codes address accumulations of fluid without a retinal break, with synonyms including "serous macular detachment." Retinal breaks without detachment are catalogued under H33.3 and include specific lesions such as horseshoe tears and round holes, which commonly appear with terms like "retinal tear without detachment." Traction detachment of retina (H33.4) indicates detachment caused by pulling forces, often related to diabetic eye disease. Lastly, H33.8 covers other retinal detachments like those caused by high myopia, useful when unspecified types are diagnosed. These codes together provide a detailed framework for documenting retinal separation conditions across varying presentations and severities.
