2021 ICD-10-CM Diagnosis Code S80

Superficial injury of knee and lower leg

    2016 2017 2018 2019 2020 2021 Non-Billable/Non-Specific Code
  • S80 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2021 edition of ICD-10-CM S80 became effective on October 1, 2020.
  • This is the American ICD-10-CM version of S80 - other international versions of ICD-10 S80 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 (S80) and the excluded code together.
