Factors influencing health status and contact with health services
ICD-10 code Z00-Z99 for Factors influencing health status and contact with health services
Note: Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a
procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease,
injury or external cause classifiable to categories A00-Y89 are recorded as 'diagnoses' or 'problems'. This can arise
in two main ways:
(a) When a person who may or may not be sick encounters the health services for some specific purpose, such
as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic
vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
(b) When some circumstance or problem is present which influences the person's health status but is not in itself a
current illness or injury.
