Y43: Primarily systemic agents

Y43.2: Antineoplastic natural products

Antineoplastic natural products refer to specific medications used in the treatment of cancer. These medications are made from natural sources like plants, animals, or microorganisms and are designed to inhibit or prevent the maturation and proliferation of cancerous cells. These products may be associated with certain undesired effects or complications, which are captured under the ICD-10 code Y43.2. The complications can occur when the drug is correctly prescribed and properly administered, indicating that these are not due to any error in clinical management but rather an adverse reaction within the individual patient's body. Symptoms of these unwanted effects can vary widely, as the reaction can impact multiple body systems. Severity can range from mild to severe. This includes but is not limited to, nausea, hair loss, fatigue, pain, and immune system suppression.
