Section F.2 / In context

Where this filing sits in Louisiana and in 2021

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 41 of the 66 Louisiana filings (62%) and on 76% of all filings submitted in 2021. Email appears on 33% of Louisiana filings.

No business associate is recorded on the filing; 32% of Louisiana filings do involve one. At 34,862 individuals the breach is 5.0 times the Louisiana median filing of 6,909 and 8.7 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.

Louisiana's breach notification statute (La. R.S. 51:3071 et seq.) requires notice to affected residents in the most expedient time possible and without unreasonable delay, no later than 60 days from discovery. Its attorney general threshold: all breaches affecting Louisiana 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 34,862 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 $5.58M; the 2026 edition's $192 gives $6.69M. Both are modelled estimates with the method shown, not costs disclosed by Lafourche Medical Group. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 1.0 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.

Lafourche Medical Group (LMG) has paid $480,000 to the Office for Civil Rights (OCR) at the U.S. Department of Health and Human Services (HHS) and agreed to implement a corrective action plan to settle potential violations of the Health Insurance Portability and Accountability Act (HIPAA) Privacy, Security, and Breach Notification Rules. LMG is a Louisiana medical group specializing in emergency medicine, occupation medicine, and laboratory testing.

On May 28, 2021, LMG filed a breach report with HHS stating that a hacker, through a successful phishing attack on March 30, 2021, gained access to an email account that contained electronic protected health information (ePHI). The type of ePHI involved included names, addresses, dates of birth, dates of service, email addresses, telephone numbers, medical record numbers, insurance/health plan beneficiary numbers, guarantor names, diagnoses, and lab results for approximately 34,862 individuals.

OCR's investigation revealed that, prior to the 2021 reported breach, LMG failed to conduct a risk analysis to identify potential threats or vulnerabilities to ePHI across the organization as required by HIPAA. OCR also discovered that LMG had no policies or procedures in place to regularly review information system activity to safeguard protected health information against cyberattacks.

In addition to the monetary settlement, LMG will undertake a robust corrective action plan that includes two years of monitoring.

Section F.5 / Modelled cost

Modelled cost / method shown, not a disclosed cost

Modelled

IBM 2025 customer PII, $160 per record

$5.58M

34,862 x $160

IBM 2026 customer PII, $192 per record

$6.69M

34,862 x $192

Method: individuals affected, as reported by Lafourche Medical Group 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

Louisiana statute and the HIPAA rule

State notification statute

Louisiana: La. R.S. 51:3071 et seq.

Database Security Breach Notification Law

Notice to individuals
In the most expedient time possible and without unreasonable delay, no later than 60 days from discovery
Attorney general threshold
All breaches affecting Louisiana residents (Within 10 days of distributing notices to residents)
Private right of action
Limited: Civil action for actual damages from failure to give timely notice, not for the breach itself
Penalty
Unfair trade practice; up to $5,000 per violation per day for AG-notification failures

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.
