Z73.3: Stress, not elsewhere classified

Stress, which is categorized under ICD-10 code Z73.3, refers to a condition that results from adverse psychological reactions to excessive pressure or demands. Stress can become harmful when it becomes ongoing or chronic, without any periods of relaxation or relief, leading to a state of constant alertness that is detrimental to the body and mind. Physical symptoms commonly include headaches, upset stomach, elevated blood pressure, chest pain, and difficulty sleeping. Emotional effects can be wide-ranging but can often involve feelings of anxiety, restlessness, irritability, and sadness. While everyone experiences stress to some degree, the level at which it becomes distressing or damaging varies greatly among individuals. Chronic stress can lead to or exacerbate other physical or mental health issues, emphasizing the importance of managing stress levels.
