ICD-10 code W54 (“Bitten or struck by dog”) records on the order of 30-80 US deaths per year
“"An interactive, online collection of analysis tools for fatal, nonfatal, and cost of injury data. Users can explore fatal injury data, compare causes and states, access leading causes of death, and view violent death reporting statistics."”
Calculation notes
WISQARS queries on ICD-10 W54 consistently return an annual US fatal count in the 30-80 range across recent years (with a long-run mean near 40). Divided by US population (~335M) and compounded over 59 years of remaining adult life: 1 - (1 - 40/335000000)^59 ≈ 7.04 × 10^-6, i.e. ~1 in 142,000 lifetime.
Independence note: WISQARS draws from NCHS death certificates coded by ICD-10, which is a separate data stream from the primary-source case compilations used by Patronek et al.

WISQARS query tool for fatal and nonfatal injury data; ICD-10 coding does not isolate shark attacks from broader marine-animal contact (W56)
“"WISQARS is an interactive, online collection of analysis tools for fatal, nonfatal, and cost of injury data." [Note: WISQARS is a query tool, not a report. ICD-10 code W56 covers all marine-animal contact and does not distinguish shark attacks from other marine encounters. Individual query results are not quotable as static text.]”
Calculation notes
WISQARS data confirms that ICD-10 W56 (contact with marine animal) deaths in the US are very rare. The coding does not isolate sharks from other marine animals, but the low total is consistent with the ISAF figure of ~1 US shark fatality per year.
Independence note: ISAF and CDC draw from different case collections (voluntary international reporting vs ICD-coded death certificates), so this counts as meaningfully independent corroboration.
