Z13.7Encounter for screening for genetic and chromosomal anomalies

Non-billable headerICD-10-CM

Z13.7 is a non-billable header ICD-10-CM code for encounter for screening for genetic and chromosomal anomalies. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • genetic testing for procreative management (Z31.4-)

Other codes that can never be billed with Z13.7

These codes carry an Excludes1 note pointing at Z13.7. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z13.7 alone.

  • Z31.43Encounter for genetic testing of female for procreative management
  • Z31.44Encounter for genetic testing of male for procreative management

Risk adjustment

Z13.7 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead Z13.7
