What changes an ER claim in Massachusetts.
Every Massachusetts 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 | Massachusetts named no state law setting out-of-network ER rates, so the federal No Surprises Act IDR process decides out-of-network ER professional payment for state-regulated plans (per CMS enforcement letter). | Source |
| Medicaid ER policy | Apr 2024 | MassHealth requires no member copayments at all (130 CMR 450.130, page dated 1 Apr 2024), so there is no non-emergency ED copay to collect or deduct on MassHealth claims. | Source |
| Blue plan | Nov 2025 | Blue Cross Blue Shield of Massachusetts: from DOS 3 Nov 2025, pre-payment edits review professional level 4 and 5 E/M (including ED visits 99284-99285) against claim severity and may pay a lower E/M level. Applies to commercial, FEP and Medicare Advantage. | Source |
| Medicare contractor | Dec 2021 | Medicare Part B ER professional claims in Massachusetts go to National Government Services (NGS), Jurisdiction K (JK). | Source |
How we bill Massachusetts 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.
