Emergency medicine billing services: what ER groups should demand in 2027

Short answer: demand seven named reports, an IDR Gateway process built for 50-line batches, pre-bill leveling checks on 99284 and 99285, and an enrollment tracker before go-live. Ask every vendor the same questions in the same order and score the answers.

Demand 1

The reports, by name, before you sign

Standing reports, not requests; our first weekly governance review for a new ER group used exactly these.

Clean claim and payer acknowledgment	Share of submitted claims confirmed received by the payer, rejections by reason	Weekly
ED level distribution	99281 to 99285 and critical care mix by physician and payer, billed versus paid	Monthly
Downcode and leveling adjustments	Level 4 and 5 adjustments by payer and policy; resubmit versus appeal decisions; overturn rate	Monthly
Out-of-network pipeline	Claims by pathway, open negotiation stage, disputes initiated, ineligible with reason, determinations, cash	Monthly
Enrollment status	Every physician's payer enrollment and effective dates, claims held for enrollment	Weekly until clean then monthly
Denials by root cause	Enrollment, eligibility, coding, authorization, timely filing, with dollars and age	Monthly

Demand 2

No Surprises Act capability you can inspect

Out-of-network claims are the revenue most at risk of a quiet write-off. Ask the vendor to walk one claim from remit to determination under the November 2026 and January 2027 rules [1] [2].

Demand 3

Leveling defense on both sides of the encounter

The same payers re-level the professional and the facility claim from one encounter. UHC's 2026R6003A and 2026R6007A use the Optum EDC Analyzer's three inputs [4]; Cigna R36, Aetna and Florida Blue re-level professional claims on diagnosis, and R36 rejects cloned notes [6].

Control	What good looks like	Ask to see
Pre-bill level check	Every 99284 and 99285 scored against payer diagnosis lists and MDM	A screen or report from the submit gate
Documentation feedback to physicians	Per-physician MDM prompts; monthly level distribution with peer comparison	The last three monthly physician reports
POS 23 rule	No ED visit code leaves with a non-ED place of service; OIG found $922,524 overpaid on 9,749 such codes [8]	The scrubber rule
Appeal file by payer and policy	Templates for R36, 26-088, UHC and Anthem with the prudent layperson citation	Two recent overturned appeals
Critical care capture	Total time per practitioner documented; 99291 from 30 minutes, 99292 once 104 minutes are reached [7]	The 99291 to 99285 ratio by physician

Our denial prediction engine scores every line before submission against more than 80 CARC patterns. Appeal method: the prudent layperson standard. Critical care: The ED Operator on 99291.

Demand 4

Enrollment and the hospital feed, owned end to end

Most ER group revenue leaks happen before coding.

Takeaway

Ask for the enrollment tracker before you ask about coding accuracy. In our experience, enrollment is where the first month's denials come from.

FAQ

Frequently asked questions

What reports should an ER group require from its billing company?

Charge lag and coding throughput by physician and hold reason; clean claim and payer acknowledgment rates; ED level distribution billed versus paid; leveling adjustments by payer with appeal outcomes; the out-of-network pipeline by pathway and stage; enrollment status for every physician; and denials by root cause. Weekly for the first 90 days, then monthly.

What No Surprises Act capabilities should emergency medicine billing services have in 2027?

An IDR Gateway account with named administrators, batching under the 50-line cap, a tracker for the plan payment, open negotiation and cooling-off clocks, fee payment before the offer deadline, remark code routing for N877 and N876 from January 2027, and a low, explained ineligible rate.

Why does provider enrollment matter so much for ER group billing?

Because ER physicians usually join a hospital-staffed department and bill many payers from day one. In our measured baseline for a new ER and hospitalist group, 45 of 46 remittance denials in the first four weeks were caused by provider enrollment rather than coding.

Should an independent ER group care about facility ED leveling policies?

Yes. The facility claim and the professional claim come from the same encounter and the same payers re-level both from claim data. A billing partner should run pre-bill level checks on 99284 and 99285 and hold appeal templates for UHC, Anthem, Cigna R36 and Florida Blue 26-088.
