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.

Key ICD-10-CM Codes for Diseases of the Eyelid, Lacrimal System, and Orbit

H00	Hordeolum	A painful, localized infection or inflammation commonly referred to as a stye, often affecting the eyelid's oil glands.
H01	Other inflammation of the eyelid	This code covers various non-specific inflammations of the eyelid that do not fall under the category of hordeolum.
H02	Other disorders of the eyelid and periocular area	These codes address a range of eyelid and periocular conditions, including cysts, deformities, and other non-inflammatory disorders.
H03	Disorders of the eyelid in diseases classified elsewhere	This code is used when eyelid disorders are secondary to other underlying medical conditions.
H04	Disorders of the lacrimal system	This code pertains to disorders related to the tear-producing and draining system of the eye.
H05	Disorders of the orbit	These codes are used for various disorders affecting the bony socket or orbit housing the eye, including inflammations, tumors, and fractures.
H06	Disorders of the lacrimal system and orbit in diseases classified elsewhere	Similar to H03, this code is used when lacrimal system and orbit disorders are secondary to other medical conditions.
