Hordeolum externum
ICD-10 H00.01 is a used to indicate a diagnosis of hordeolum externum.
Hordeolum externum, commonly known as an external stye, is an acute inflammatory condition affecting the eyelid, typically resulting from the infection of the sebaceous glands of Zeis or the sweat glands of Moll. Clinically, it presents as a localized, painful, red swelling on the eyelid margin, often accompanied by tenderness and sometimes purulent discharge. The anatomy involved includes the eyelid structures, particularly the meibomian glands, which can become obstructed and infected. Disease progression may lead to the formation of a pus-filled abscess, which can rupture spontaneously, providing symptomatic relief. Diagnostic considerations include a thorough clinical examination, where the characteristic appearance of the stye is usually sufficient for diagnosis. In some cases, differential diagnoses such as chalazion or other eyelid lesions may need to be ruled out. Treatment typically involves warm compresses to promote drainage, and in persistent cases, incision and drainage may be necessary. Antibiotic therapy may be indicated if secondary bacterial infection is suspected.

H00.01 specifically covers external hordeolum, characterized by acute inflammation of the eyelid margin due to glandular infection. It does not cover internal hordeolum or other eyelid lesions.
H00.01 should be used when the clinical presentation is consistent with an external stye, particularly when there is localized swelling and tenderness on the eyelid margin, differentiating it from internal hordeolum or chalazion.
Documentation should include a detailed clinical examination noting the presence of swelling, tenderness, and any discharge. Treatment plans and follow-up notes are also essential to support the diagnosis.
