Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- This category is to be used for newborns, within the neonatal period (the first 28 days of life), who are suspected of having an abnormal condition, but without signs or symptoms, and which, after examination and observation, is ruled out.
Other codes that can never be billed with Z05
These codes carry an Excludes1 note pointing at Z05. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z05 alone.
- Z03Encounter for medical observation for suspected diseases and conditions ruled out
Risk adjustment
Z05 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.
