What has happened to this code

Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
Inherited from M99 Biomechanical lesions, not elsewhere classified
Note
- This category should not be used if the condition can be classified elsewhere.
