Fall from, out of or through building or structure (W13)

The ICD-10 code W13 and its extensions classify falls from, out of, or through various types of buildings or structures, such as balconies, bridges, roofs, floors, windows, and other architectural elements. These codes are used to document and specify the exact type of fall-related injury source for accurate medical coding.

The ICD-10 code for fall from balcony (W13.0XX) covers incidents commonly referred to as "fall from building" or "fall from balcony." Similarly, W13.1XX codes apply to falls from bridges, including injuries described as falls from a high man-made structure. Falls through roofs are coded under W13.2XX, also linked with terms like "fall through roof." Injuries from falls through floors, windows (W13.3XX and W13.4XX, respectively) specify the location of the fall more precisely. The category W13.8XX incorporates falls from other structures such as flagpoles, towers, or chimneys, while W13.9XX captures falls from buildings that are not otherwise specified. Each subcategory includes initial, subsequent, and sequela encounters to track the course of treatment following the incident. These codes help medical coders accurately capture the external cause of injury related to falls from specific parts of a building or structure.

Instructional Notations

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
