Section F.2 / In context

Where this filing sits in Maryland and in 2016

OCR classifies the incident as a hacking or IT incident, with the breached information held in a desktop computer. Hacking/IT Incident is the type recorded on 117 of the 170 Maryland filings (69%) and on 35% of all filings submitted in 2016. Desktop Computer appears on 5% of Maryland filings.

No business associate is recorded on the filing; 38% of Maryland filings do involve one. At 10,000 individuals the breach is 2.1 times the Maryland median filing of 4,792 and 2.5 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 10,000 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 $1.60M; the 2026 edition's $192 gives $1.92M. Both are modelled estimates with the method shown, not costs disclosed by Maryland Medical Center/Dr. Morrill. 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.

On November 3, 2016, a cyber-attacker accessed the covered entity's (CE) practice computer system to deny access to certain portions of its computer system until a ransom was paid. The CE, Maryland Medical Center, shut down the system and utilized its backup to recover the lost information. The compromised information consisted of correspondence to patients regarding test results utilizing patient names, date of birth, social security number. The documents targeted by the virus affected approximately 10,000 individuals. After the compromise, the CE put the computer system in safe mode, conducted a virus scan, and quarantined and destroyed computer viruses. The CE confirmed that it closed the system network and password protected the Wi-Fi. The CE implemented a procedure requiring pre-approval of all electronic devices connected to its systems and requiring a firewall for remote access to the virtual private network (VPN). The CE sanctioned the employee responsible for the breach and retrained all employees. OCR reviewed the CE's current risk assessment and obtained assurances that the CE implemented the corrective actions listed.

10,000 x $160

IBM 2026 customer PII, $192 per record

10,000 x $192

Method: individuals affected, as reported by Maryland Medical Center/Dr. Morrill 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

Private right of action
No: No PROA under the breach statute; AG enforcement only
Penalty

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.
