Susan B. Allen Memorial Hospital: 11,866 individuals, Sep 2025.

OCR classifies the incident as a hacking or IT incident, with the breached information held in a desktop computer and a network server. Hacking/IT Incident is the type recorded on 59 of the 80 Kansas filings (74%) and on 81% of all filings submitted in 2025. Desktop Computer appears on 8% of Kansas filings.

No business associate is recorded on the filing; 21% of Kansas filings do involve one. At 11,866 individuals the breach is 1.5 times the Kansas median filing of 7,757 and 3.0 times the national median of 4,000 across all 7,884 filings. It sits in the 10,000 to 99,999 band, which holds 1,938 filings.

As of 28 August 2026 the case is listed by HHS OCR under Cases Currently Under Investigation. OCR has not published a closing summary, so this page is limited to the fields on the filing itself; the archive entry that follows a closed investigation usually adds a short account of what was exposed and what the entity did afterwards.

Kansas's breach notification statute (K.S.A. 50-7a01 et seq.) requires notice to affected residents in the most expedient time possible and without unreasonable delay. Its attorney general threshold: no general AG requirement (reporting agencies at more than 1,000 residents). The HIPAA Breach Notification Rule ran alongside it: notice to affected individuals and to HHS without unreasonable delay and no later than 60 days after discovery, which is the clock that put this filing on the portal.

Multiplying 11,866 individuals by IBM's $160 customer-PII cost per record (Cost of a Data Breach 2025, the figure the site's calculator uses) gives a modelled $1.90M; the 2026 edition's $192 gives $2.28M. Both are modelled estimates with the method shown, not costs disclosed by Susan B. Allen Memorial Hospital. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.3 times the sector average.
