Section F.2 / In context

Where this filing sits in Puerto Rico and in 2011

OCR classifies the incident as theft, with the breached information held in a desktop computer. Theft is the type recorded on 25 of the 32 Puerto Rico filings (78%) and on 62% of all filings submitted in 2011. Desktop Computer appears on 16% of Puerto Rico filings.

No business associate is recorded on the filing; 56% of Puerto Rico filings do involve one. At 24,361 individuals the breach is 3.1 times the Puerto Rico median filing of 7,911 and 6.1 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.

Puerto Rico is outside the site's 50-state statute table, so no state deadline is shown; the HIPAA Breach Notification Rule still applied, requiring notice to affected individuals and to HHS without unreasonable delay and no later than 60 days after discovery.

Multiplying 24,361 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 $3.90M; the 2026 edition's $192 gives $4.68M. Both are modelled estimates with the method shown, not costs disclosed by PMC Medicare Choice. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.7 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.

Thieves broke into the PMC Medicare Choice facility located in Humacao, Puerto Rico and stole four unencrypted desktop computers containing 24,361 health plan members' electronic protected health information (ePHI). The ePHI included names, addresses, phone numbers, Medicare HIC numbers, diagnosis and treatment information, health plan names, health plan member identification numbers, health plan enrollment information, health care claim information, and social security numbers. The covered entity (CE) provided breach notification to HHS, affected individuals, and the media. Following the breach, the CE repaired a damaged wall and improved security at the facility and the surrounding premises. OCR obtained assurances that the CE implemented the corrective actions noted above. As a result of OCR's investigation, the CE encrypted all computers located at its regional offices. OCR stated its expectation that the CE will perform a thorough and accurate risk analysis and establish a risk management plan. In addition, OCR stated an expectation that the CE will implement contingency operations procedures, implement its facility security plan's policies and procedures, and regularly patch and update its IT infrastructure. OCR also stated an expectation that the CE will encrypt and decrypt ePHI where appropriate and document the technical safeguards implemented to prohibit the unauthorized copying and removal of PHI and ePHI.

24,361 x $192

Method: individuals affected, as reported by PMC Medicare Choice 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.
