Z71.1: Person with feared complaint in whom no diagnosis is made

The ICD-10 code Z71.1 refers to a category of patients called "Person with feared complaint in whom no diagnosis is made." This title is given to those who are highly concerned, stressed, or anxious about the possibility of a serious illness, to the point that it significantly affects their daily life, despite not being diagnosed with such illness by health professionals. Often these individuals seek multiple medical consultations and diagnostic tests which fail to reveal any specific medical condition. In these cases, the person's worry about having a certain disease may not ease even with reassurance from doctors. While no physical symptoms may be identified, this persistent worry and preoccupation with having an illness may cause considerable emotional distress and could possibly lead to interaction with healthcare services similar to those with actual diagnosed illnesses.
