Code Range
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.

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.

About the W65–W74 Code Range
ICD-10 codes W65-W74 cover accidental, non-transport-related drowning and submersion incidents, specifying the location and circumstances of these events. These codes help identify accidental drownings in settings like bathtubs, swimming pools, natural water, or other specified or unknown situations.
This range includes precise classifications for drowning accidents occurring in a bathtub (W65), swimming pools (W67), and natural water bodies like lakes or oceans (W69). Each has subcodes denoting the nature of healthcare encounters: initial (XXXA), subsequent (XXXD), or sequela (XXXS). For example, common terms like accidental submersion in a bath or drowning while swimming correspond to these codes, aiding coders in matching clinical notes to the correct code. The section also includes broader categories such as other specified causes (W73) which cover drowning related to various recreational activities, water sports, or occupational hazards not otherwise classified. Finally, W74 codes address unspecified drowning causes, including near drowning, “dry drowning,” or drowning during rescue attempts, supporting careful coding when exact causes are unclear. These detailed codes ensure accurate documentation of diverse accidental drowning events outside of transport scenarios.
