What changes an ER claim in Ohio.
Every Ohio 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 | Apr 2021 | ORC 3902.51: no balance billing for OON emergency care. Plan pays the greatest of its median in-network rate, its usual OON method, or Medicare; provider may negotiate instead, then after 30 days seek Ohio DOI arbitration (3902.52: billed over $750, up to 15 claims bundled). | Source |
| Medicaid ER policy | Jul 2021 | Ohio Medicaid $3 copay for non-emergency ED visits sits in the hospital rule (OAC 5160-2-77): ODM deducts it from the hospital ED claim, not the ER physician claim; under-21 and other 5160-1-09 exclusions apply. | Source |
| Medicaid managed care | Sep 2025 | Buckeye Health Plan OH.PP.076 (all products incl. Medicaid), effective 1-Sep-2025: professional ED E&M levels are leveled so the billed code must match services performed; claims above the supported level are adjusted. | Source |
| Blue plan | Nov 2026 | Anthem Ohio Medicaid reimbursement policy G-19002, Emergency Department Leveling of E/M Services (approved Dec 18, 2025, effective Nov 1, 2026), sets the facility ED E/M level from the intensity of resources on the claim and may deny, adjust or recoup higher levels. | Source |
| Medicare contractor | Nov 2023 | Medicare Part B professional claims in Ohio go to CGS Administrators, A/B MAC Jurisdiction 15 (J15), with Kentucky. | Source |
How we bill Ohio 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.
