What changes an ER claim in Hawaii.
Every Hawaii 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 | CMS: Hawaii identified no state law setting the out-of-network rate, so the federal No Surprises Act IDR process decides ER out-of-network payment for state-regulated plans in Hawaii, and CMS enforces the IDR outcome there. | Source |
| Medicare contractor | Sep 2025 | Hawaii Part B (professional) claims go to Noridian Healthcare Solutions, A/B MAC Jurisdiction E (JE), which also covers California, Nevada, American Samoa, Guam and the Northern Mariana Islands. | Source |

How we bill Hawaii 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 Hawaii.
Does Hawaii have a state surprise billing law for ER care?
CMS: Hawaii identified no state law setting the out-of-network rate, so the federal No Surprises Act IDR process decides ER out-of-network payment for state-regulated plans in Hawaii, and CMS enforces the IDR outcome there.
Which Medicare contractor processes Hawaii ER professional claims?
Hawaii Part B (professional) claims go to Noridian Healthcare Solutions, A/B MAC Jurisdiction E (JE), which also covers California, Nevada, American Samoa, Guam and the Northern Mariana Islands.
How are emergency department visit levels chosen in Hawaii?
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 Hawaii 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 Hawaii 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.
