Heart of America Medical Center ("HAMC"): 29,430 individuals, Jul 2025.

OCR classifies the incident as a hacking or IT incident, with the breached information held in a network server. Hacking/IT Incident is the type recorded on 15 of the 21 North Dakota filings (71%) and on 81% of all filings submitted in 2025. Network Server appears on 43% of North Dakota filings.

No business associate is recorded on the filing; 19% of North Dakota filings do involve one. At 29,430 individuals the breach is 4.6 times the North Dakota median filing of 6,457 and 7.4 times the national median of 4,000 across all 7,927 filings. It sits in the 10,000 to 99,999 band, which holds 1,950 filings.

As of 10 September 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.

North Dakota's breach notification statute (N.D. Cent. Code Ch. 51-30) requires notice to affected residents in the most expedient time possible and without unreasonable delay. Its attorney general threshold: 250 or more North Dakota 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 29,430 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 $4.71M; the 2026 edition's $192 gives $5.65M. Both are modelled estimates with the method shown, not costs disclosed by Heart of America Medical Center ("HAMC"). For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.9 times the sector average.
