Z04.71 — Encounter for examination and observation following alleged adult physical abuse
Z04.71 is a billable, specific ICD-10-CM code for encounter for examination and observation following alleged adult physical abuse. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Suspected adult physical abuse, ruled out
Other codes that can never be billed with Z04.71
These codes carry an Excludes1 note pointing at Z04.71. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z04.71 alone.
- T76Adult and child abuse, neglect and other maltreatment, suspected
Risk adjustment
Z04.71 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
Z04.71 is named in 6 Medicare coverage policies — 6 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
