E/M downcoding and bundling errors cost EDs recoverable revenue every shift.
Emergency medicine bills high-acuity E/M, critical care, and same-visit procedures under time pressure, MDM documentation gaps, modifier 25 misses, and observation status errors add up fast. Manual billing teams catch a fraction of the errors. Ember catches all of them.

Where emergency medicine revenue leaks
The denial patterns Ember was built for
Emergency departments bill high-acuity E/M, critical care, and same-visit procedures in compressed windows, and each line has its own denial trap. MDM downcoding, time documentation gaps, and status-of-care errors compound into systematic underpayment. Ember closes each gap.
01 · E/M downcoding & MDM gaps
High-acuity ED visits downcoded when MDM elements aren't captured in the note.
Payers audit ED E/M against documented problems, data reviewed, and risk, and a note that doesn't reflect the work drives 99285 to 99284 or lower. High-volume departments lose revenue visit by visit. Ember scores MDM against the chart before the claim submits and flags the documentation gap while the encounter is still fresh.
99285 · 99284 · 99283 · 9928202 · Critical care & procedure bundling
Critical care time billed with E/M or procedures without the right modifiers.
Critical care requires documented time and excludes other E/M on the same date unless criteria are met. Procedures performed during the ED visit need modifier 25 when a separately identifiable E/M is supported. Missing time, wrong bundling, or absent modifiers trigger denials and takebacks. Ember validates time, bundling, and modifier logic against NCCI and payer edits.
99291 · 99292 · Mod 25 · 1200103 · Observation & status-of-care
Observation, inpatient, and place-of-service denials on extended ED stays.
Payers scrutinize whether observation hours, inpatient admission, or continued ED care meet medical-necessity and timing rules. Status chosen without supporting documentation becomes a full denial or a paid-at-lower-rate adjustment. Ember flags missing criteria before disposition and builds the appeal when payers push back.

Audit upstream.
Appeal downstream.
Two workflows do most of the work for emergency departments. The first prevents denials before they happen. The second recovers the ones that slip through.
Pre-bill audit
Catch the missing modifier 25 before the claim leaves.
Ember reviews every encounter against coding standards, payer ED policy, and your contracts. E/M downcoding risk, critical care bundling, and status-of-care gaps are flagged before submission.
- 1
Ingest the encounter
Pulls ED notes, nursing flowsheets, procedure documentation, critical care time, and disposition orders from your EHR.
- 2
Validate against rules
Checks E/M MDM against documentation, critical care time and bundling, modifier 25 on procedures, and observation/inpatient criteria against each payer's policies.
- 3
Recommend with citation
Returns the suggested correction tied to the exact payer policy, NCCI edit, or contract term.
- 4
Educate the provider
Coding patterns drive provider-level coaching, so MDM documentation and procedure modifier use improve across every shift.
