Z63.4 — Disappearance and death of family member
Z63.4 is a billable, specific ICD-10-CM code for disappearance and death of family member. It is valid for submission on a claim.
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.
