I believe it would be coded to "adverse effect of selective serotonin reuptake inhibitors," T43.225, with a 7th character of A, D, or S, as appropriate.
T43.225x is an adverse effect code and should not be used without code(s) for the associated effects, and cannot be used as principal diagnosis for inpatient admissions. It can only be used as principal diagnosis in an outpatient setting if no specific effects are documented. For inpatient coding, you would code the actual effects before T43.225x code.

Question:
What is the correct code for serotonin syndrome secondary to Prozac and Nardil?
Answer:
Note from 3M :
As of October 1, 2009, code 969.0, Poisoning by psychotropic agent, Antidepressants, has been further expanded to provide a unique code for each of the common current classes of antidepressants.
The answer would depend on the diagnostic statement of the attending physician. If the physician states that the syndrome is due to an adverse effect of medication properly administered, assign code 333.99, Other and unspecified extrapyramidal diseases and abnormal movement disorders, and E939.0, Antidepressants causing adverse effects in therapeutic use. If however, the physician states that the syndrome is due to an overdose, or inappropriately administered medication, assign codes 969.0, Poisoning by psychotropic agents, antidepressants, 333.99, Other and unspecified extrapyramidal diseases and abnormal movement disorders, and E854.0, Accidental poisoning by other psychotropic agents, antidepressants. If this is a suicide attempt, assign codes 969.0, 333.99, and E code, E950.3, Suicide and self-inflicted poisoning by solid or liquid substances, tranquilizers and other psychotropic agents.
