Z00.12Encounter for routine child health examination

Non-billable headerICD-10-CM

Z00.12 is a non-billable header ICD-10-CM code for encounter for routine child health examination. 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.

  • health check for child under 29 days old (Z00.11-)
  • health supervision of foundling or other healthy infant or child (Z76.1-Z76.2)
  • newborn health examination (Z00.11-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Health check (routine) for child over 28 days old
  • Immunizations appropriate for age
  • Routine developmental screening of infant or child
  • Routine vision and hearing testing

Other codes that can never be billed with Z00.12

These codes carry an Excludes1 note pointing at Z00.12. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z00.12 alone.

  • Z00.0Encounter for general adult medical examination
  • Z00.11Newborn health examination

Risk adjustment

Z00.12 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 Z00.12

2 child codes. Green means billable.
