What changes an ER claim in Montana.
Every Montana 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 | Montana has no state out-of-network rate law; the federal No Surprises Act IDR process decides out-of-network ER professional payment for state-regulated plans, and CMS directly enforces several NSA provider rules in MT. | Source |
| Medicaid ER policy | Jan 2020 | Montana Healthcare Programs removed all member cost-share references from its provider manual effective 1 Jan 2020, so no Medicaid copay (including for non-emergency ER use) is collected from members. | Source |
| Blue plan | Jul 2026 | Blue Cross and Blue Shield of Montana (commercial): from DOS 1 Jul 2026, professional office, inpatient and outpatient E&M claims are edited and paid at a lower validated level if billed services do not support the E&M level (AMA MDM rules); submit records to dispute. | Source |
| Medicare contractor | Aug 2025 | Medicare Part B ER professional claims in Montana go to Noridian Healthcare Solutions, Jurisdiction F (JF). CMS re-awarded JF to Noridian on 19 Aug 2025. | Source |
How we bill Montana 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.
