Section F.2 / In context
Where this filing sits in Maine and in 2022
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 30 of the 37 Maine filings (81%) and on 79% of all filings submitted in 2022. Network Server is the most common location in the state, appearing on 62% of Maine filings.
A business associate is recorded as present on the filing, as it is on 22% of Maine filings. At 11,938 individuals the breach is 2.8 times the Maine median filing of 4,229 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 in the HHS OCR breach portal archive. OCR's closing summary of the case is reproduced in full below.
Maine's breach notification statute (10 M.R.S. 1346 et seq.) requires notice to affected residents as expediently as possible and without unreasonable delay, no later than 30 days after discovery. Its attorney general threshold: all breaches (no minimum resident threshold). 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 11,938 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 $1.91M; the 2026 edition's $192 gives $2.29M. Both are modelled estimates with the method shown, not costs disclosed by Central Maine Medical Center. 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.
Section F.3 / OCR closing summary
The portal's archived description, in full
Written by the Office for Civil Rights when the case was closed and reproduced verbatim from the HHS export.
The covered entity (CE), Central Maine Medical Center, reported that its business associate (BA) experienced a data breach that affected the protected health information (PHI) of 11,938 individuals. The PHI involved included names, addresses, dates of birth, Social Security numbers, and clinical information. The BA notified HHS, affected individuals, the media, and posted substitute notice on its website. In response to the breach, the BA offered free credit monitoring and strengthened its administrative and technical safeguards.

Method: individuals affected, as reported by Central Maine Medical Center to HHS, multiplied by IBM's customer-PII cost per record (Cost of a Data Breach 2025 Figure 6 and the 2026 edition). No cost has been disclosed by the entity for this filing; the figure is a planning estimate, not a fact about the breach. IBM's per-record figures come from mid-volume breaches and IBM cautions against applying them to breaches involving millions of records; the site's per-record page explains where the multiplication holds and where it breaks down.
Context: IBM's average cost of a healthcare breach is $6.64M in the 2026 report ($7.42M in 2025); the global average across all sectors was $4.44M in 2025.

Portal: ocrportal.hhs.gov breach report. Statutory basis: HITECH Act section 13402(e)(4): the Secretary must post a list of breaches of unsecured protected health information affecting 500 or more individuals. Breaches affecting fewer than 500 individuals are reported to OCR annually and are not posted, so they are not on this register. Status wording follows the portal's two tabs ("Cases Currently Under Investigation" and "Archive") as of 28 August 2026; a filing moves to the archive when OCR closes the case. Modelled costs on this site are a method applied to the reported count, using IBM Cost of a Data Breach per-record figures, and are never a cost disclosed by the entity.
