What has happened to this code

Every change the publisher made, from 2007 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

  1. FY2007 Added to the draft code set draft Poisoning by centrally-acting and adrenergic-neuron- blocking agents, intentional self-harm, initial encounter
  2. FY2010 Draft description revised draft Poisoning by centrally-acting and adrenergic-neuron- blocking agents, intentional self-harm, initial encounter Poisoning by centrally-acting and adrenergic-neuron-blocking agents, intentional self-harm, initial encounter

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 T44 Poisoning by, adverse effect of and underdosing of drugs primarily affecting the autonomic nervous system

Seventh character required

  • The appropriate 7th character is to be added to each code from category T44

Inherited from the T36-T50 section Poisoning by, adverse effects of and underdosing of drugs, medicaments and biological substances (T36-T50)

Excludes1 - never coded here

  • toxic reaction to local anesthesia in pregnancy (O29.3-)

Excludes2 - not included here

  • abuse and dependence of psychoactive substances (F10-F19)
  • abuse of non-dependence-producing substances (F55.-)
  • immunodeficiency due to drugs (D84.821)
  • drug reaction and poisoning affecting newborn (P00-P96)
  • pathological drug intoxication (inebriation) (F10-F19)

Use additional code

  • code(s) to specify:
  • manifestations of poisoning
  • underdosing or failure in dosage during medical and surgical care (Y63.6, Y63.8-Y63.9)
  • underdosing of medication regimen (Z91.12-, Z91.13-)

Code first

  • , for adverse effects, the nature of the adverse effect, such as:
  • adverse effect NOS (T88.7)

  • blood disorders (D56-D76)
  • contact dermatitis (L23-L25)
  • dermatitis due to substances taken internally (L27.-)

  • poisoning by overdose of substance
  • poisoning by wrong substance given or taken in error
  • underdosing by (inadvertently) (deliberately) taking less substance than prescribed or instructed

Note

  • The drug giving rise to the adverse effect should be identified by use of codes from categories T36-T50 with fifth or sixth character 5.

How CDC's index refers to this code

Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.
