Non-Billable/Non-Specific Code

T20 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
The 2023 edition of ICD-10-CM T20 became effective on October 1, 2022.
This is the American ICD-10-CM version of T20 - other international versions of ICD-10 T20 may differ.

Type 2 Excludes

Type 2 Excludes Help

A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (T20) and the excluded code together.
