Coding notes

  • Not to be used for chronic poisoning and harmful exposure. Code these to current poisoning and harmful exposure.
  • Categories T90-T98 are to be used to indicate conditions in S00-S99 and T00-T88 as the cause of late effects, which are themselves classified elsewhere. The "sequelae" include those specified as such, or as late effects, and those present one year or more after the acute injury.

Codes in T90–T98

Based on the World Health Organization’s International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10), 2019 version, and the national editions published by each country’s health authority.
