How we bill South Carolina ER visits.
The same four-step workflow we run for emergency medicine and hospitalist groups billing from their hospital system.
Hospital feed and registration
Demographics, insurance and the attending physician arrive from the hospital system daily. Gaps go back to registration as clarification requests, not guesses.
MDM levels and critical care minutes
ED visits 99281-99285 are coded on medical decision making only. Critical care is 99291 for 30 to 74 minutes and 99292 from 104 total minutes, on documented time.
Modifier 25 and enrollment check
A separately identifiable E/M on the day of a procedure carries modifier 25 with its own documentation. The rendering physician is checked against the payer roster before release.
Submission, remit and NSA/IDR
Professional claims go out with place of service 23. Out-of-network ER claims follow the No Surprises Act: in-network cost share only, open negotiation, then federal IDR.
FAQ: ER billing in South Carolina.
Does South Carolina have a state surprise billing law for ER care?

What does South Carolina Medicaid require for ED visits?
SC Medicaid (Physicians Manual, 1 Oct 2026): hospital-based ER physicians bill on CMS-1500 and must document whether the visit was an emergency; Medicaid pays only one ER visit per day for the same or related diagnosis.
Which Medicare contractor processes South Carolina ER professional claims?

How are emergency department visit levels chosen in South Carolina?
By medical decision making only. CMS states that for emergency department visits practitioners use MDM, not time, to select 99281-99285, so the note must carry the problems addressed, the data reviewed and the risk of management.
Can an out-of-network ER physician in South Carolina bill the patient for the balance?
Not for covered emergency services. Under the federal No Surprises Act, out-of-network providers of emergency services cannot bill the patient more than in-network cost sharing, and the notice-and-consent exception does not apply to emergency medicine.
