About the H10–H11 Code Range
ICD-10 codes H10-H11 cover various disorders of the conjunctiva, the clear tissue lining the inside of the eyelids and covering the white of the eye. This range includes conjunctivitis types, conjunctival degenerations, scars, cysts, vascular abnormalities, and other specific conjunctival conditions.
The H10 series primarily codes for conjunctivitis and its subtypes, such as mucopurulent conjunctivitis (H10.0), acute atopic conjunctivitis (H10.1), toxic (chemical) conjunctivitis (H10.21), and chronic variants like giant papillary conjunctivitis (H10.41). Synonyms like "purulent conjunctivitis" or "allergic conjunctivitis" help coders link clinical terms back to their appropriate codes. Codes distinguish affected eye laterality and specify whether the condition is bilateral or unspecified. The H11 codes address other conjunctival issues, including pterygium (H11.0), conjunctival degenerations and deposits (H11.1), scarring (H11.2), hemorrhages (H11.3), vascular disorders (H11.4), and cysts. This range also encompasses less common disorders like pinguecula, symblepharon, and conjunctivochalasis. Detailed synonyms assist in identifying conditions such as "ocular rosacea" (H10.82) or "pseudopterygium" (H11.81). The codes carefully specify the affected eye when possible, aiding accurate clinical documentation and billing for conjunctival health conditions.
