Guidelines tip
From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
These codes are not used when the examination is for diagnosing a suspected condition or for treatment. Conditions discovered are coded as additional codes, and an exam with abnormal findings needs a code for each finding.
Excludes1
Not coded here. The listed conditions generally should not be reported together.
- encounter for examination of sign or symptom- code to sign or symptom
- general health check-up of infant or child (Z00.12.-)
Excludes2
Not included here. Both codes may be reported if the patient has both conditions.
Inclusion terms
Conditions classified to this code.
- Encounter for adult periodic examination (annual) (physical) and any associated laboratory and radiologic examinations
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.
