2025 ICD-10-CM code S00.12

Contusion of the left eyelid and periocular area.

Use secondary codes from Chapter 20 (External causes of morbidity) to specify the cause of the injury. If a retained foreign body is present, use an additional code from Z18.-.

Medical necessity is established by the presence of a contusion to the left eyelid and periocular area, typically caused by trauma. The need for diagnostic tests and treatment is determined by the severity of the injury and associated symptoms.

Providers diagnose the condition based on patient history, physical examination, assessment of visual acuity and eye motion, and imaging (X-rays or MRIs if a fracture is suspected). Treatment includes ice, rest, pain medication (e.g., acetaminophen), antibiotics (if infection is present), and eye drops to reduce inflammation.

In simple words: A black eye on the left side, caused by a bruise to the eyelid and the area around the eye.

Contusion (bruise) of the left eyelid and the surrounding periocular area.

Example 1: A patient presents with swelling and discoloration around the left eye after being struck by a ball during a baseball game., A child falls off a swing and lands on their face, resulting in a bruise to the left eyelid and surrounding tissues., An adult sustains a left black eye during a physical altercation, with no other apparent injuries.

Documentation should include the cause and mechanism of injury, the location and extent of the contusion, associated symptoms (e.g., pain, swelling, visual disturbances), and any diagnostic tests performed (e.g., visual acuity assessment, imaging studies).

** This code describes a contusion (bruise) without a laceration (cut).If there is a cut present, a different code should be used. If the injury involves the eyeball itself, a code from category S05 should be used.
