Fall from, out of or through building or structure (W13) ICD-10-CM
The W13 code range covers fall from, out of or through building or structure with 29 ICD-10-CM diagnosis codes. 21 of them are billable and valid for claim submission in fiscal year 2027, 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 W13
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 W13 Code Range
These falls involve a building or structure, including falls from, out of, or through it.

Each subdivision ends with a character for the encounter: A for initial, D for subsequent, or S for sequela, a later effect.
