Foreign body on external eye (T15) ICD-10-CM
The T15 code range covers foreign body on external eye with 53 ICD-10-CM diagnosis codes. 36 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- foreign body in penetrating wound of orbit and eye ball S05.4 S05.5
- open wound of eyelid and periocular area S01.1
- retained foreign body in eyelid H02.8
- retained old foreign body in penetrating wound of orbit and eye ball H05.5 H44.6 H44.7
- superficial foreign body of eyelid and periocular area S00.25
7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- The appropriate 7th character is to be added to each code from category T15
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
- A - initial encounter
- D - subsequent encounter
- S - sequela

About the T15 Code Range
The ICD-10 code T15 covers injuries caused by a foreign body on the external eye, including the cornea, conjunctival sac, and other external parts. These codes are essential for accurately documenting and treating cases of eye injuries due to particles or objects like splinters or metal fragments.
Each subcode under T15 specifies the exact location and laterality of the foreign body, such as the cornea (e.g., T15.0 series) or conjunctival sac (e.g., T15.1 series), and details the encounter type, including initial treatment, subsequent care, or sequela. For example, the ICD-10 code for a corneal foreign body includes terms like "corneal rust ring" or "splinter in cornea" (found under T15.00XA), which helps coders use the right code when treating specific injuries. Similarly, foreign bodies trapped in the conjunctival sac or eyelid area use related codes like T15.10, encompassing synonyms like "orbital foreign body."
These distinctions guide healthcare providers and coders in choosing the precise code for injuries involving foreign bodies accidentally entering the eye, improving communication and care planning. The codes also differentiate by eye side—right or left—and by the phase of care, making them integral for comprehensive eye injury documentation in medical records.
