What changes an ER claim in Wyoming.
Every Wyoming 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 | No Wyoming payment standard for out-of-network ER physicians: CMS found WY named no state law governing the out-of-network rate, so federal No Surprises Act IDR applies, and CMS directly enforces the NSA provider and insurer rules in Wyoming. | Source |
| Medicaid ER policy | Jan 2026 | Wyoming Medicaid: pays ER practitioners (hospital-based, under arrangement, or called in) for 99281-99288; the practitioner must document in the record whether the ER visit was a true emergency, and should report suspected ER overuse to WYhealth. | Source |
| Blue plan | Jun 2025 | Blue Cross Blue Shield of Wyoming raised Evaluation and Management (E&M) reimbursement effective 6/1/2025, covering ED E/M codes; the notice gives no percentage, so check your updated fee schedule with Provider Relations (1-888-666-5188). | Source |
| Medicare contractor | Jul 2026 | Medicare Part B ER claims in Wyoming go to Noridian Healthcare Solutions, A/B MAC Jurisdiction F (JF). | Source |
How we bill Wyoming 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.
