Section F.2 / In context

Where this filing sits in North Carolina and in 2015

OCR classifies the incident as theft, with the breached information held in another location. Theft is the type recorded on 18 of the 207 North Carolina filings (9%) and on 30% of all filings submitted in 2015. Other appears on 4% of North Carolina filings.

A business associate is recorded as present on the filing, as it is on 26% of North Carolina filings. At 20,512 individuals the breach is 5.6 times the North Carolina median filing of 3,679 and 5.1 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.

North Carolina's breach notification statute (N.C. Gen. Stat. 75-65) requires notice to affected residents without unreasonable delay. Its attorney general threshold: all breaches (Consumer Protection Division of the AG). 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 20,512 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 $3.28M; the 2026 edition's $192 gives $3.94M. Both are modelled estimates with the method shown, not costs disclosed by Medical Management, LLC (MML). For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.6 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.

Medical Management LLC provides billing services as a business associate (BA) for more than 30 medical facilities in various states, with BA agreements in place for each covered entity (CE). On March 16, 2015, the IRS notified the BA that one of its employees was involved in an identity theft ring. The employee confessed to the activity and was terminated. The BA determined that, during her employment, the employee had access to 30,556 patient's records containing protected health information (PHI), including demographic information (names, dates of birth and social security numbers). The BA notified each CE of the breach, established a call center, sent letters to the potentially affected individuals on behalf of its CEs, offered credit monitoring and ID theft protection, sent media notice to 12 newspapers, and notified HHS. In response to the breach, the BA upgraded to an improved billing system with more security controls, masked social security numbers where appropriate, and retrained its staff. In addition, the BA implemented software for tracking and monitoring access and user activity, which is monitored by IT staff, in order to identify any abnormal access. OCR obtained assurances that the BA implemented the corrective actions listed above.

IBM 2026 customer PII, $192 per record

20,512 x $192

Method: individuals affected, as reported by Medical Management, LLC (MML) 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.
