Non-billable header

Z77 is a non-billable header code. Use one of the more specific codes below.

Inclusion terms

Includes

  • contact with and (suspected) exposures to potential hazards to health
  • 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:
  • Note: (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.
  • Note: (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.
