Protected health information (PHI)
Individually identifiable health information protected under U.S. HIPAA rules.
Also called: PHI
In plain English
PHI includes data that can identify a patient and relates to their health, care, or payment for care — for example name plus diagnosis, or member ID plus claim details.
Billing companies handle PHI when they build claims, work denials, and post remittance for client practices.
Why it matters
How you store, access and disclose PHI is a legal and contractual obligation, not just an IT preference.
A claim for J. Alvarez with CPT 99214 and member ID is PHI once it can identify that person.
Tenant isolation, role scoping and an immutable audit log are designed for PHI workloads; demos on this site use synthetic data only.

Common questions
Is MEDBIX an EHR?
No. MEDBIX is a revenue cycle and medical billing platform. It can take in billing-relevant data from EHRs, but it doesn't do clinical charting, prescriptions or labs.
Does the AI submit claims automatically?
No. AI agents suggest codes, explain scrub findings and propose denial fixes. A person on your team has to review and approve every claim before it goes to the clearinghouse.
Who can see our data?
Your billing company is the tenant. Practices under you are separated by permissions, and other billing companies can't see your data at all, because PostgreSQL row-level security enforces it.
Can a solo practice use it?
Yes. A solo practice onboards as its own tenant, with the provider or office manager as the tenant admin.
Which clearinghouse do you use?
Stedi, a modern JSON clearinghouse API, for eligibility (270/271), claims (837) and remittance (835).
