Section F.2 / In context

Where this filing sits in Maryland and in 2022

OCR classifies the incident as a hacking or IT incident, with the breached information held in email. Hacking/IT Incident is the type recorded on 117 of the 170 Maryland filings (69%) and on 79% of all filings submitted in 2022. Email appears on 30% of Maryland filings.

A business associate is recorded as present on the filing, as it is on 38% of Maryland filings. At 14,538 individuals the breach is 3.0 times the Maryland median filing of 4,792 and 3.6 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.

Maryland's breach notification statute (Md. Code, Com. Law 14-3504) requires notice to affected residents within 45 days after discovery or notification of the breach. Its attorney general threshold: all breaches (AG notified before individual notices are sent). 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 14,538 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 $2.33M; the 2026 edition's $192 gives $2.79M. Both are modelled estimates with the method shown, not costs disclosed by CareFirst Administrators. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.4 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), CareFirst Administrators, reported that multiple employees of its business associate (BA) were the victims of an email phishing attack that affected the protected health information (PHI) of 14,538 individuals. The PHI involved included names, dates of births, addresses, Social Security numbers, diagnoses, medications, other treatment information, and claims information. The BA notified the affected individuals; the CE notified HHS, the media, and posted substitute notice on its website. In response to the breach the CE provided complimentary credit monitoring services to affected individuals while the BA implemented additional administrative and technical safeguards.

$2.33M

14,538 x $160

IBM 2026 customer PII, $192 per record

14,538 x $192

Method: individuals affected, as reported by CareFirst Administrators 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.

Section F.6 / Notification clock

Maryland statute and the HIPAA rule

State notification statute

Maryland: Md. Code, Com. Law 14-3504

Notice to individuals
Within 45 days after discovery or notification of the breach
Attorney general threshold
All breaches (AG notified before individual notices are sent) (Before individual notifications are sent)
Private right of action
No: No PROA under the breach statute; AG enforcement only
Penalty
Unfair or deceptive trade practice; up to $10,000 per violation, $25,000 per repeat violation

The HIPAA Breach Notification Rule runs alongside the state statute: notice to affected individuals and to HHS without unreasonable delay and no later than 60 days after discovery.

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.
