Clinical Description of ICD-10 Code T36

Definition

The T36 code encompasses a range of conditions related to systemic antibiotics, which are medications used to treat infections caused by bacteria. This code specifically addresses three main scenarios:
1. Poisoning: This refers to instances where an overdose of systemic antibiotics occurs, leading to toxic effects.
2. Adverse Effects: This includes any harmful or unintended reactions that arise from the use of systemic antibiotics, even when administered at therapeutic doses.
3. Underdosing: This situation occurs when a patient receives less than the prescribed amount of antibiotic, potentially leading to treatment failure or worsening of the infection.

Specificity

The T36 code can be further specified with additional characters to indicate the exact nature of the adverse effect or poisoning. For example, T36.95XA refers to the "Adverse effect of unspecified systemic antibiotic," which is used when the specific antibiotic causing the adverse effect is not identified[1][3].
