Non-Billable/Non-Specific Code

Z22 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
The 2023 edition of ICD-10-CM Z22 became effective on October 1, 2022.
This is the American ICD-10-CM version of Z22 - other international versions of ICD-10 Z22 may differ.

Type 2 Excludes

Type 2 Excludes Help

A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (Z22) and the excluded code together.

2023 ICD-10-CM Range Z00-Z99
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.
