Testing to confirm or rule out a suspected diagnosis because of a sign or symptom is diagnostic, not screening. A screening code can be first-listed when the visit is for the screening.
Excludes1
Not coded here. The listed conditions generally should not be reported together.
- encounter for diagnostic examination-code to sign or symptom
Excludes2

Notes
Also from chapter/block level (4 notes)
- Nonspecific abnormal findings disclosed at the time of these examinations are classified to categories R70-R94.
- 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.
