Verify Codes in The Tabular List
The first guideline for coding from the TDC is always refer back to the Tabular List. All codes in the TDC require a seventh character to indicate the timing of the encounter. For example, accidental Ranitidine poisoning is coded T47.0X1A Poisoning by histamine H2-receptor blockers, accidental (unintentional), initial encounter for the initial encounter or T47.0X1D Poisoning by hi…
