The ICD-10 code T45 pertains to "Poisoning by, adverse effect of and underdosing of primarily systemic and hematological agents, not elsewhere classified." This code is part of a broader classification system used for documenting various health conditions, particularly those related to poisoning and adverse drug reactions.

Clinical Description

Definition

ICD-10 code T45 is used to classify cases involving poisoning, adverse effects, or underdosing related to systemic and hematological agents. These agents can include a wide range of medications and substances that affect the body's systems, particularly those that influence blood and hematological functions. The code is specifically designated for situations where the poisoning or adverse effects do not fall under more specific categories.

Categories of T45

The T45 code is further divided into subcategories that provide more detailed classifications:

• T45.0: Poisoning by anticoagulants and antiplatelet agents.
• T45.1: Poisoning by other systemic agents, including various medications that may cause adverse effects.
• T45.2: Adverse effects of systemic agents, which can include reactions to medications that are not classified as poisoning.
• T45.3: Underdosing of systemic agents, indicating situations where a patient has not received an adequate dose of a medication, potentially leading to adverse health outcomes.
