ICD-10-CM External Causes of Injury Index — T
Look up how an injury occurred. External cause codes are secondary codes; they never appear as the principal diagnosis.
72 entries. An entry marked — has no code of its own; follow "see" to the listed term. An unmarked entry without a code is a heading for the entries beneath it.
