2025 ICD-10-CM code T39.0
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Poisoning - Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances (T36-T50) Injury, poisoning and certain other consequences of external causes (S00-T88) Feed
Poisoning by, adverse effect of, and underdosing of salicylates.
Modifiers may be applicable depending on the circumstances of the encounter and the services rendered.Consult the appropriate modifier guidelines for details.
Medical necessity for coding T39.0 depends on the presence of a clinically significant adverse effect, poisoning, or overdose.The documentation should support the clinical findings and demonstrate the need for treatment and care rendered.The intent of the exposure may also play a role in determining medical necessity, especially in cases of intentional self-harm or misuse.
The clinical responsibility for coding T39.0 falls on the physician or healthcare provider directly involved in the patient's care.They must accurately document the diagnosis, the circumstances surrounding the salicylate ingestion or exposure, the specific adverse effects observed, and any treatment administered.This detailed documentation is crucial for accurate code assignment and appropriate reimbursement.

In simple words: This code is used when someone gets sick or has a bad reaction because of taking too much, too little, or the wrong type of salicylate medicine, such as aspirin.It also applies if the medicine was used correctly but still caused a negative reaction.Doctors will use additional codes to describe exactly what happened.
This ICD-10-CM code encompasses poisoning, adverse effects, and underdosing resulting from salicylates.It includes instances of accidental ingestion, intentional overdose, and errors in medication administration.The code requires further specification using additional codes to pinpoint the nature of the adverse effect and the specific salicylate involved.Additional codes from categories T36-T50 (with 5th or 6th character 5) should be used to identify the specific drug causing the adverse effect.If applicable, use additional codes to specify manifestations of poisoning, underdosing, or dosage failures during medical or surgical care (Y63.6, Y63.8-Y63.9), or underdosing of a medication regimen (Z91.12-, Z91.13-).
Example 1: A 70-year-old male patient presents to the emergency department after accidentally ingesting a large quantity of aspirin, experiencing gastrointestinal distress and tinnitus.The provider diagnoses aspirin poisoning (T39.0) with gastrointestinal symptoms (specify with additional code)., A 25-year-old female patient is admitted to the hospital for intentional self-harm by aspirin overdose.She displays symptoms consistent with salicylate poisoning (T39.0) and requires intensive care.Additional codes would specify the intentional self-harm and the severity of the poisoning., A pediatric patient develops an allergic reaction (e.g., urticaria, angioedema) after receiving a prescribed dose of baby aspirin. The provider diagnoses an adverse effect of salicylates (T39.0) and documents the allergic reaction using additional codes, linking the adverse effect to the appropriate salicylate via T36-T50 codes.
Comprehensive documentation is crucial.This includes the type and amount of salicylate ingested or administered, the time of ingestion or exposure, the patient's symptoms, laboratory results (e.g., salicylate levels), and the treatment provided.The intent of the exposure (accidental, intentional, undetermined) must also be clearly documented.
** The 7th character (A, D, or S) should be appended to indicate the encounter status: A (initial encounter), D (subsequent encounter), S (sequela).This code should be used in conjunction with additional codes to fully capture the clinical picture.
