What changes an ER claim in Oregon.
Every Oregon 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 |
|---|---|---|---|

Only 2 rules are verified for Oregon so far. A missing row means we could not verify a rule against its primary source yet, not that none exists. The 50-state ER matrix is re-checked and extended on each release.
How we bill Oregon 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 Oregon.
Does Oregon have a state surprise billing law for ER care?
ORS 743B.287: out-of-network providers may not bill state-regulated plan enrollees for emergency services beyond in-network cost sharing. Oregon sets no OON rate for ER pros; CMS says federal NSA IDR applies to payment disputes.
Which Medicare contractor processes Oregon ER professional claims?
Medicare Part B (professional) claims are processed by Noridian Healthcare Solutions, Jurisdiction F (JF). CMS re-awarded JF to Noridian on 19 Aug 2025.
How are emergency department visit levels chosen in Oregon?
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 Oregon 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.
When can 99292 be billed to Medicare for a Oregon ER patient?
Under the Medicare Claims Processing Manual, 99291 covers 30 to 74 minutes of critical care on a date, and 99292 can be reported only when a further full 30 minutes is furnished, which is 104 total minutes.
