Counsel for emergency physician groups, emergency departments, and ambulance providers on out-of-network payment, medical necessity, and documentation audits.
Emergency medicine is paid under a different set of rules than a scheduled office visit. The visit may be out of network, the patient did not choose the clinician, and the record has to support both the medical need and the level of service. Rivet Health Law advises emergency groups, emergency departments, and EMS providers when those rules turn into denials or audits.

The Challenge
Patients often have no practical choice of emergency clinician. Federal and state rules, plus the group’s contract if there is one, decide what the plan must pay and what the patient may be billed. Arguing the chargemaster does not answer which of those rules applies.

Who We Help
This work is reimbursement work with a short clock. Joseph Rivet’s background is in how claims are coded, reviewed, and taken back, including medical-necessity and specialty care transport audits. The file starts with the record and the payment standard, not with a generic demand.
Our Process
These steps organize the file. They are not a substitute for counsel.
Separate emergency department claims from ambulance claims. They have different rules and deadlines.
For a physician or facility underpayment, pull the remittance, the applicable contract or payment standard, and one chart.
For transport denials, sort them into medical necessity, level of service, and destination.
Calendar the oldest appeal deadline before you build a larger sample.
Downcoding of emergency visits has the same shape as office downcoding, with a worse record problem. The note is written once, under time pressure. If the level billed is not in that note, the appeal has little to stand on.
Medicare ambulance payment generally requires a medically necessary transport, to an appropriate destination, by a qualified crew, documented at the time. A certification that says “bedbound” does not carry the claim if the narrative describes a patient who could have traveled another way.
Specialty care transport is not another name for advanced life support. It is a level used when the patient needs care during transport beyond what an EMT-paramedic provides. If the interventions on the run sheet do not match that level, the claim is exposed even when the transport itself was necessary.
