Other and unspecified injuries of head (S09) ICD-10-CM
The S09 code range covers other and unspecified injuries of head with 100 ICD-10-CM diagnosis codes. 69 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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 S09
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.

About the S09 Code Range
The ICD-10 code S09 covers a broad range of other and unspecified injuries of the head, including injuries to muscles, tendons, blood vessels, ears, nose, and face. These codes are used to document head injuries that do not fit into more specific categories elsewhere in the ICD-10 system.
This section includes detailed codes such as S09.0XXA for traumatic injury of blood vessels of the head, helping identify injuries like artery or vein trauma. Codes like S09.11XA represent strains of muscles and tendons of the head, encompassing conditions such as mentalis strain or tendon injuries. Traumatic rupture of eardrums is coded under headings like S09.21XA, which specify the affected ear (right, left, bilateral, or unspecified). For middle and inner ear injuries, codes such as S09.301A capture injuries also known as traumatic injuries of the right or left middle ear. The collection also addresses unspecified injuries of the head and face under codes like S09.90XA and S09.93XA, including manifestations like traumatic epistaxis (nosebleeds), dental trauma, or splinters in soft tissues. Synonyms provided for many codes aid in linking common clinical terms—such as "traumatic tympanic membrane perforation" or "blast injury to ears"—to their corresponding ICD-10 codes, helping medical coders accurately assign codes based on detailed injury descriptions.
