Y63: Failure in dosage during surgical and medical care

Y63.6: Nonadministration of necessary drug, medicament or biological substance

Nonadministration of necessary drug, medicament or biological substance refers to a situation where a patient does not receive an essential medication or substance that their health condition requires. This can occur due to various reasons such as errors in prescription, misunderstanding of instructions, systemic issues in healthcare delivery or even patient non-compliance. The non-administration can result in a lack of expected improvement in the patient's condition, or potentially cause a worsening of symptoms. The effects can range across all body systems and are entirely dependent on the purpose of the medication or biological substance that was supposed to be administered. It's critical that healthcare providers closely monitor and ensure the right medications are given to patients as prescribed, and that patients understand the importance of adhering to their medication plans.
