Unacceptable principal diagnosis
There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to Z15.07: its own notes plus those printed at Z15.0, Z15, and Chapter 21. A note printed at a category, block or chapter applies to every code under it.

Notes

General instructions on how these codes are used.

From Chapter 21 (Z00-Z99) Factors influencing health status and contact with health services applies to 1,425 codes
  • 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.

Questions About Z15.07Overview

What is the ICD-10 code for genetic susceptibility to malignant neoplasm of urinary tract?

The ICD-10-CM code for genetic susceptibility to malignant neoplasm of urinary tract is Z15.07 (sometimes written as Z1507). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Z15.07 (Genetic susceptibility to malignant neoplasm) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report genetic susceptibility to malignant neoplasm of urinary tract on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does Z15.07 group to?

On inpatient claims, genetic susceptibility to malignant neoplasm of urinary tract maps to MS-DRG 951 (other Factors Influencing Health Status), which carries a relative weight of 0.5574. Higher weights mean higher Medicare reimbursement.

Can Z15.07 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because genetic susceptibility to malignant neoplasm of urinary tract describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z15.07 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for genetic susceptibility to malignant neoplasm of urinary tract on inpatient claims. The code appears in the Genetic carrier and genetic susceptibility to disease (Z14-Z15) range of the CMS exempt list.
