The ICD 10 Code H00-H59 serves as a comprehensive system, aiding medical professionals in the precise diagnosis and classification of a wide range of eye and adnexa diseases. In this blog, we venture into eye health, providing an in-depth exploration of ICD 10 Code H00-H59.
ICD-10-CM Code H00-H06: Diseases of the Eyelid, Lacrimal System, and Orbit
ICD-10-CM Code H00-H06 encompasses a set of codes that pertain to various diseases and disorders related to the eyelid, lacrimal (tear) system, and orbit (the bony socket that houses the eye). Within this range, we find detailed classifications for conditions such as hordeolum (commonly known as a stye), inflammations of the eyelid, disorders affecting the lacrimal system (responsible for tear production and drainage), and disorders of the orbit.
