What changes an ER claim in South Dakota.
Every South Dakota rule on file, each linked to its primary source: state surprise-billing law, Medicaid ER policy, Medicaid managed care, the Blue plan and the Medicare contractor.
| Rule type | Date | What it says | Source |
|---|---|---|---|
| State surprise-billing law | Dec 2021 | South Dakota identified no state law setting the out-of-network rate, so ER pros paid out of network by state-regulated plans follow the federal No Surprises Act: patient owes in-network cost share only, payment disputes go to federal IDR. | Source |
| Medicaid ER policy | Dec 2025 | SD Medicaid: ED pros bill 99281-99285 under the prudent layperson standard. For PCP/Health Home (Care Management) recipients, urgent non-emergent ED care needs a referral; without one only the ER room and the screening exam are paid. Retro referrals allowed. | Source |
| Medicare contractor | Aug 2025 | Medicare Part B (professional) claims are processed by Noridian Healthcare Solutions, Jurisdiction F (JF). CMS re-awarded JF to Noridian on 19 Aug 2025. | Source |
How we bill South Dakota 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.

How are emergency department visit levels chosen in South Dakota?
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.

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.
