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 Y99 External cause status

Note

A single code from category Y99 should be used in conjunction with the external cause code(s) assigned to a record to indicate the status of the person at the time the event occurred.

Inherited from the Y90-Y99 section Supplementary factors related to causes of morbidity classified elsewhere (Y90-Y99)

Note

These categories may be used to provide supplementary information concerning causes of morbidity. They are not to be used for single-condition coding.
