To distinguish among poisoning, adverse effect, or underdosing by drugs, medicinal, and biological substances (T36-T50) when assigning ICD-10-CM diagnostic codes, consider the following definitions: Poisoning indicates improper use of a medication, to include overdose, wrong substance given or taken in error, or wrong route of administration.
When reporting poisoning by drugs, biological, and biological substances, assign the appropriate poisoning code first, followed by the manifestation code (s). For example, a patient intentionally takes several Amitriptyline in an attempted suicide, which causes a Grand mal seizure.
T40.0 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail. The 2022 edition of ICD-10-CM T40.0 became effective on October 1, 2021.
The 2022 edition of ICD-10-CM T50.904 became effective on October 1, 2021. This is the American ICD-10-CM version of T50.904 - other international versions of ICD-10 T50.904 may differ. Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury.

Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code. Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.
In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere.". Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code.
Toxic effects are coded first using category codes T51 – T65. This block of codes has a guideline that states to use an additional code for associated manifestations. You still must locate these codes using the TDC. For example, rubbing alcohol is a harmful substance that is not meant to be ingested.
Here’s how to tell the difference: Poisoning is the improper use of medication. Toxic effects are also coded using the TDC. Toxic effects occur when a harmful substance is ingested or comes in contact with a person. An adverse effect occurs when a drug has been correctly prescribed and properly administered.
Underdosing is defined as taking less of a drug than is recommended by a provider or the manufacturer.
Overdose of a drug (intentional), taken or administered and resulting in toxicity is a poisoning.
Poisoning codes are sequenced first. You can remember this by thinking of what is addressed first when the patient presents: the poisoning. Poisoning can happen in many different circumstances. Four situations are provided in the ICD-10-CM guidelines:
Error in drug prescription can be made by a patient, a nurse, a caregiver, or a provider.
Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances. Code First. , for adverse effects, the nature of the adverse effect, such as:
