Fall on same level from slipping, tripping and stumbling (W01)

The ICD-10 code W01 and its detailed subcodes describe falls on the same level due to slipping, tripping, or stumbling, with distinctions based on whether the person struck an object afterward. These codes capture specific fall incidents including whether the fall caused injury from hitting items like glass, tools, furniture, or other objects.

Use W01 codes to identify injuries resulting from slips, trips, or stumbles occurring without a change in elevation. The subcategories (e.g., W01.0XXA) specify whether the individual subsequently struck an object and the nature of that object, such as sharp glass or a power tool. These codes also differentiate between the initial encounter, subsequent treatment, or complications (sequela). Common terms related to these codes include falls due to wet or polished surfaces and tripping over loose carpets, helping coders connect lay descriptions like “fall from slipping” to the precise ICD-10 codes for accurate documentation and billing. The classifications assist in detailing the cause and circumstances of falls, critical for injury reporting and treatment planning.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

  • fall on moving sidewalk

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • fall due to bumping striking against object W18.0
  • fall in shower or bathtub W18.2
  • fall on same level NOS W18.30
  • fall on same level from slipping, tripping and stumbling due to ice or snow W00.0
  • fall off or from toilet W18.1
  • slipping, tripping and stumbling NOS W18.40
  • slipping, tripping and stumbling without falling W18.4

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 W01

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela
