Overdose <strong>of</strong> a drug intentionally taken<br />
If an overdose <strong>of</strong> a drug was intentionally taken or<br />
administered <strong>and</strong> resulted in drug toxicity, it would be<br />
coded as a poisoning (960-979 series).<br />
Nonprescribed drug taken with correctly prescribed<br />
<strong>and</strong> properly administered drug<br />
If a nonprescribed drug or medicinal agent was taken in<br />
combination with a correctly prescribed <strong>and</strong> properly<br />
administered drug, any drug toxicity or other reaction<br />
resulting from the interaction <strong>of</strong> the two drugs would be<br />
classified as a poisoning.<br />
Interaction <strong>of</strong> drug(s) <strong>and</strong> alcohol<br />
When a reaction results from the interaction <strong>of</strong> a<br />
drug(s) <strong>and</strong> alcohol, this would be classified as<br />
poisoning.<br />
Sequencing <strong>of</strong> poisoning<br />
When coding a poisoning or reaction to the improper<br />
use <strong>of</strong> a medication (e.g., wrong dose, wrong substance,<br />
wrong route <strong>of</strong> administration) the poisoning code is<br />
sequenced first, followed by a code <strong>for</strong> the<br />
manifestation. If there is also a diagnosis <strong>of</strong> drug abuse<br />
or dependence to the substance, the abuse or<br />
dependence is coded as an additional code.<br />
See Section I.C.3.a.6.b. if poisoning is the result <strong>of</strong><br />
insulin pump malfunctions <strong>and</strong> Section I.C.19 <strong>for</strong><br />
general use <strong>of</strong> E-codes.<br />

Toxic effect codes<br />
When a harmful substance is ingested or comes in<br />
contact with a person, this is classified as a toxic effect.<br />
The toxic effect codes are in categories 980-989.<br />
Sequencing toxic effect codes<br />
A toxic effect code should be sequenced first, followed<br />
by the code(s) that identify the result <strong>of</strong> the toxic effect.<br />
External cause codes <strong>for</strong> toxic effects<br />
An external cause code from categories E860-E869 <strong>for</strong><br />
accidental exposure, codes E950.6 or E950.7 <strong>for</strong><br />
intentional self-harm, category E962 <strong>for</strong> assault, or<br />
