Section F.2 / In context

Where this filing sits in Mississippi and in 2016

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 39 of the 55 Mississippi filings (71%) and on 35% of all filings submitted in 2016. Network Server is the most common location in the state, appearing on 55% of Mississippi filings.

No business associate is recorded on the filing; 33% of Mississippi filings do involve one. At 64,000 individuals the breach is 12 times the Mississippi median filing of 5,220 and 16 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.

Mississippi's breach notification statute (Miss. Code Ann. 75-24-29) requires notice to affected residents without unreasonable delay. Its attorney general threshold: no AG notification requirement at any 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 64,000 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 $10.2M; the 2026 edition's $192 gives $12.3M. Both are modelled estimates with the method shown, not costs disclosed by Urgent Care Clinic of Oxford. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 1.9 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 August 2, 2016, the covered entity (CE), Urgent Care Clinic of Oxford, discovered that its server was hacked by an unauthorized third party. The CE investigated and determined that the hackers gained access to the server through an administrative account set up by the CE's technology contractor. The types of protected health information (PHI) involved in the breach included patient names, addresses, dates of birth, driver's licenses, social security numbers, claims information, diagnoses and conditions, lab results, and medications, affecting approximately 64,000 individuals. The CE provided breach notification to HHS, affected individuals, and the media. In response to the breach, the CE immediately shut down its server's remote access, contacted law enforcement, hired forensic investigators and installed a new network sonic wall to protect its entire system. OCR provided technical assistance to the CE regarding risk analysis and risk management. Consequently, the CE altered its policies and procedures to include full monthly testing of its server and a new risk assessment in accordance with OCR's Security Risk Assessment Tool. Moreover, the CE retrained its workforce on its updated policies and procedures. OCR obtained assurances that the CE implemented the corrective actions listed above.

$10.2M

64,000 x $160

IBM 2026 customer PII, $192 per record

$12.3M

64,000 x $192

Method: individuals affected, as reported by Urgent Care Clinic of Oxford 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.
