Guidelines tip
From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
Z05 is for a healthy newborn evaluated for a suspected condition that is ruled out. If there are signs or symptoms, the sign or symptom is coded instead. On a birth record, Z05 follows the Z38 code.
Excludes2
Not included here. Both codes may be reported if the patient has both conditions.
Inclusion terms
Conditions classified to this code.
- This category is to be used for newborns, within the neonatal period (the first 28 days of life), who are suspected of having an abnormal condition, but without signs or symptoms, and which, after examination and observation, is ruled out.
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.
