Z55.0: Illiteracy and low-level literacy

Illiteracy and low-level literacy, as categorized under ICD-10 code Z55.0, refers to a condition where an individual has limited or no ability to read or write. This inability significantly affects their daily life and their comprehension of health and wellness information, impacting communication and understanding in critical situations. These conditions arise not from a medical disease or disorder, but from socio-economic factors like deprivation, lack of education or inadequate learning resources and support during the schooling years. Illiteracy and low-level literacy might not present apparent physical symptoms but can reflect in the form of limited understanding, lowered ability to follow instructions, or difficulty in expressing themselves coherently. It contributes to increased health disparities and decreased overall health outcomes, often because individuals struggle to navigate healthcare systems or fail to comprehend medical advice properly.
