Trauma / Acute Care Surgery Billing Services
Trauma and acute care surgery billing starts with a patient nobody scheduled. Surgeons are called in at all hours, often to a patient who cannot give insurance details. Coverage may be unknown, and the injury may involve auto insurance, workers' compensation, or a liability claim.
Trauma surgery billing also has to reflect the work done. A single stay can include critical care, an emergency operation, a planned return to the operating room, and daily rounding. Each piece has its own coding rules. Westmont connects trauma and acute care surgery groups with vetted billing experts who understand how to document and code this work so that claims are complete and defensible.

Billing challenges in trauma and acute care surgery
- Critical care versus surgery on the same day. Critical care and an operation can both happen, but time spent on the procedure cannot be counted again as critical care. A biller experienced in trauma checks the documented time and applies the right modifier.
- Decision for surgery. An evaluation that leads to a major operation is usually bundled into the surgery's global period unless modifier 57 is used. Billers confirm that notes show the decision was made at that visit.
- Staged and repeat operations. Damage control often means a return trip to the operating room. Modifiers such as 58 (planned staged procedure) and 78 (unplanned return) change payment. Your biller matches them to the operative notes.
- Trauma activation fees. G0390 is a hospital charge, not a surgeon service, and payers set their own criteria. Surgeons should know which claims it belongs on, and billers should keep documentation consistent with the hospital.
- Unknown coverage and patient identity. Patients may arrive unconscious or without ID. Billers run eligibility after the fact, update registration, and chase retroactive coverage such as emergency Medicaid.
- Third-party and liability payers. Auto medical payments, workers' compensation, and liens can sit ahead of health insurance. Billers identify the right payer order early and track statutes and filing limits.
- Documentation gaps. Trauma notes written in a rush can miss details that support the code. Billers send clear queries, and groups can use templates to capture time and findings.

Frequently asked questions
Can a trauma surgeon bill critical care and surgery on the same day?
Often yes, but the time must be separate. Critical care time cannot include time spent on a procedure that is billed on its own. Payers also differ on when both can be paid. Notes should show the critical care time, what care was given, and why it was separate from the operation.
What does modifier 57 mean for trauma surgeons?
Modifier 57 tells the payer that an evaluation and management visit led to the decision to operate. Without it, many payers treat a visit the day before or the day of a major surgery as part of the surgical package. It is commonly used in emergency surgery, but the notes must support it.
Who pays for trauma care when the patient has no insurance?
It depends on the patient and the state. Some patients qualify for emergency Medicaid or retroactive coverage. Others have auto or liability coverage. A billing expert checks eligibility after the encounter and finds the right payer. Rules vary, so check current state and federal guidance.
Why do trauma claims get delayed?
Common causes include missing registration details, unclear accident information, and multiple possible payers. Payers may also request accident questionnaires before paying. Quick follow-up and clean patient information can shorten the wait. Keeping a clear record of every contact attempt also helps if a payer later asks why a claim was filed late.
Is G0390 billed by the surgeon?
No, G0390 is generally reported by the facility for a trauma response team activation, usually tied to a revenue code. Surgeons bill their own professional services. Both sides should keep documentation that matches so payers can see the full picture.
