ICD-10-CM Diagnosis Code S01.1: Open wound of eyelid and periocular area

ICD-10-CM code S01.1 identifies an open wound of the eyelid and periocular area, classifying it under the broader category of open head wounds. This active diagnosis concept represents an injury where the skin is damaged, potentially allowing pathogens to enter the wound. It does not possess narrower subcategories within the terminology. 1 6

Plain-language overview

An open wound of the eyelid and periocular area involves skin damage, which creates an entry point where pathogens can get into the wound. This classification helps categorize injuries specifically affecting the eye region. 6

What this code represents

Code S01.1 represents an injury or poisoning concept specifically defined as an open wound of the eyelid and periocular area, and it currently holds an active record status within the ICD-10-CM version 2026 terminology. 1

Coding details

The diagnosis code S01.1 is a child of the parent concept S01, which categorizes open wounds of the head, and the terminology record indicates this specific code has no narrower concepts. 1

Documentation considerations

Clinical documentation for related eyelid wound codes must specify details like laterality, the presence of a foreign body, and the encounter type, such as initial or sequela, to select the correct billable code. 5

If documentation mentions an eyelid scarring condition following a prior laceration with a retained foreign body, it provides the necessary elements to justify a related sequela diagnosis code. 5

Coverage and utilization context

A Medicare billing and coding article for blepharoplasty and brow lift procedures includes specific open wound codes of the right and left eyelid and periocular area within its listed diagnosis references. 2 3
