- LHC Group
- People affected
- 6,602+ (WA verified)
LHC's substitute website notice and consumer letter do not publish a nationwide total. Washington AG lists 6,602 WA residents. ClaimDepot cites Texas AG (~16,885 TX) and Massachusetts OCABR (~4,812 MA). Almeida Law Group attributes 162,578 total persons affected to Texas AG report BR-0005312 (Sept. 4, 2026). This page does not treat 162,578 as confirmed without the underlying Texas AG extract, and notes the conflict with state-only figures.

Dates come from the sources listed at the bottom of this page. Separate events are kept separate; where a date has not been disclosed, it says so.
What information was exposed?
The categories below come from LHC Group's disclosure and the sources listed on this page. Each is labeled by what the evidence supports. Categories not mentioned in any source are not listed, even if they are common in similar breaches.
Name
Full names, per company notice.
Physical address
Date of birth
Dates of birth and demographics.
Social Security number
Social Security numbers in limited instances, per company notice.
Health information
Clinical summaries, treatment plans, diagnosis codes, dates of service, physician/provider information (PHI).
Insurance information
Health insurance policy names, numbers, and plan information.
Government identification
Medicare and Medicaid ID numbers, per company notice.
Financial information
Financial information in limited instances, per company notice.
Why this information matters
The risks below are the ones associated with the categories of information involved in this breach. This describes how exposed information can be used in general. It does not state that any of this has happened with data from this incident.
Information from one breach can sometimes be combined with information from other breaches or public sources. A name and email address on their own are limited. Paired with a date of birth from one leak and an address from a people-search site, they become enough to answer a security question or make a scam call sound informed.
Whether the data from this breach has been sold, shared, or used is not known unless a source on this page says so. Where that is documented, it appears in the "What happened" section above.
If you were affected, consider doing these things now
Practical steps for this breach, in rough order of priority. None of these require buying anything. Monitoring services, including ours, are one option among several.
- 01Follow the instructions in the LHC Group notice if you received one, including IDX enrollment before December 4, 2026.
- 02Watch for phishing that references LHC Group, your home health or hospice provider, Optum/UnitedHealth, Medicare, or this breach.
- 03Verify any call or email claiming to be from LHC by using 1-866-200-0905 from your written notice or another number you already have.
- 04Because Social Security numbers may be involved in limited instances, consider a credit freeze with each of the three major credit bureaus.
- 05Review Explanation of Benefits statements, medical bills, and health-insurance accounts for services you did not receive.
- 06Check financial accounts and credit reports for activity you do not recognize.
- 07Enroll in the complimentary IDX monitoring offered in your notice if eligible.
- 08Consider a personal information monitoring service.
AI Protection
Monitoring, alerts, and recovery help for what comes after a breach.
A breach puts information you can't take back into circulation. AI Protection watches for it being misused, alerts you when something changes, and helps you recover if something goes wrong. It cannot undo the breach or retrieve data an attacker already holds.
How one breach can contribute to a larger exposure footprint
A possible risk pattern, not a description of this incident. Each step is something that can happen after a breach. Nothing here states that it has happened with data from this incident.
Illustrative pattern- Step 1
One breach
A single company's records are accessed without authorization.
- Step 2
Personal information is exposed
Some categories can be changed afterward. Others, like a name or date of birth, can't.
- Step 3
It may remain accessible
Copies of breached data can persist well beyond the original incident.
- Step 4
Sources can be combined
Fragments from different breaches and public sources may be assembled into a fuller profile.
- Step 5
More targeted attempts
A fuller profile can make fraud, impersonation, phishing, or social engineering attempts more convincing.
A breach is an event. Exposure can last longer.
A password can be reset and a card reissued. Some information can't be replaced, and that is the part that stays useful to someone attempting fraud later. This does not mean fraud will occur. It means the risk does not close when the news cycle does.
Involved in this breach and hard to change
None of the categories reported in this breach are in the hard-to-change group. Changeable items like passwords and account numbers should still be addressed.
