Change Healthcare (Optum)
The largest US medical claims clearinghouse, now part of Optum
- Founded
- 2017
- HQ
- Nashville, TN
- Stage
- Subsidiary of UnitedHealth Group (Optum)
- Raised
- n/a
What it does
- Medical, dental, and pharmacy claims clearinghouse
- Eligibility and benefits verification at scale
- Electronic remittance and payment services
- Claims editing and payment accuracy tools
- Clinical data exchange and attachments
- Patient billing and payment products
Where it's strong
- Unmatched payer connectivity: it remains the default clearinghouse route for a huge share of US claims volume.
- Breadth across medical, dental, and pharmacy transactions plus payments means one vendor can cover most exchange needs.
- Optum ownership gives it deep resources and long-term viability.
What buyers should weigh
- The February 2024 ransomware attack took its clearinghouse down for months, exposed data on roughly 192.7 million people, and cost UnitedHealth over $2B; restoration was not complete until late 2024 and litigation continues into 2026.
- Many providers now run a second clearinghouse for redundancy after the outage, and buyers should plan for the same.
- Being owned by UnitedHealth raises conflict-of-interest questions for providers and competing payers, and post-attack loan clawbacks strained provider trust.
