Inclusion terms

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

  • Assumed death of family member
  • Bereavement

Other codes that can never be billed with Z63.4

These codes carry an Excludes1 note pointing at Z63.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z63.4 alone.

  • Z63.3Absence of family member

Risk adjustment

Z63.4 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.

Medicare coverage

Z63.4 is named in 1 Medicare coverage policy 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
