Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Powered lawn mower (commercial) (residential)
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.
- contact with nonpowered lawn mower W27.1
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.
- exposure to electric current W86
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.

About the W28 Code Range
The ICD-10 code W28 is used to classify injuries resulting from contact with powered lawn mowers. This code helps document and track incidents where individuals have been involved in accidents caused by such equipment.
The section includes specific codes like W28.XXXA for the initial encounter after injury, W28.XXXD for subsequent encounters during treatment, and W28.XXXS for sequela, or late effects, of the injury. These codes are essential for accurately coding accidents caused by powered lawn mowers or horticultural cutting machines, which are common synonyms. Medical coders rely on these distinctions to reflect the stage of care related to the injury, improving clarity in medical records and billing. The ICD-10 code for contact with powered lawn mower specifically captures the cause of injury rather than the injury itself, aiding healthcare providers in categorizing external causes and facilitating injury prevention efforts.
