Billable / specificPOA exempt
Z17.420 is a billable, specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes in FY2027.
Inclusion terms
Applicable to
- HR- with HER2+
Includes (from Z17)
- 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.
- Note: Use one code, as available, for each receptor: Z17.0, Z17.1, Z17.2-, Z17.3-
Includes (from Z17.4)
- Note: Assign a code from subcategory Z17.4- when only a combined receptor status is documented
