    AAPC: Back to School
    What is the correct code for unisom poisoning? The physician chose 971.1 , but I look up the generic name for unisom in the drug table it directs me to 963.0.

    963.0 is the correct code if taken accidentally.

    I would hesitate to overrule the doc on this one as diphenhydramine HCL ( the main ingredient in Unisom) is anticholinergic. So I can see a case for either code. I would deferr to the physician on this one. Also regardless of accidental or purposeful, you would use the 963.x or the 971.x code, along with the E code for accidental poisoning or suicide intention.
