The Question · Emergency department · Downcoding
Three states now make insurers show their work before they downcode your ED claim.
Indiana, Virginia and Illinois passed downcoding laws in 2026. They require notice, a reason, a human somewhere in the decision and a long appeal window. They do not reach every ED patient. Here is what each law says and how to use it on your next remit.

What each law requires of the insurer
Read from the Indiana enrolled act, the current Virginia Code and Illinois legislature summaries.
| Rule | Indiana (IC 27-1-52) | Virginia (38.2-3407.15) | Illinois (SB 3114) |
|---|---|---|---|
| Who decides | Software cannot be the sole basis for a medical necessity downcode without a record review by a person | A person, or software that follows correct coding standards and considers all patient data on the claim | Downcoding decisions reviewed by a person, not an algorithm |
| Diagnosis-only downcode | Banned | Not named; software must weigh all documented data | Not confirmed in summaries |
| Notice to you | CARC and RARC, the reason with clinical criteria, original and new codes and amounts | Notice of the downcode with CARC and RARC on the remit | Notice with the clinical reason |
| Appeal window | At least 180 days | At least 180 days after notice; disputes decided by a person | Clear dispute process required |
| Batch appeals | Allowed for similar claims, without restriction | Allowed in batches per patient | Not confirmed in summaries |
| Targeting complex patients | Banned | Not named | Banned |
Indiana also requires insurers to disclose when AI is used to downcode a claim.
Which ED patients these laws do not reach
State insurance law governs state-regulated plans. Check plan type before you cite a statute.
Self-funded employer plans
ERISA self-funded plans sit outside state insurance law. Many large employers use them.
Medicare Advantage
Federal MA standards supersede most state law under 42 CFR 422.402. Use the MA appeal route instead.
Indiana Medicaid
Indiana's chapter excludes the Medicaid program and its managed care plans.
Fully insured commercial
State-regulated HMO and insurance policies. This is where the new rules bite.
Working an ED downcode under the new laws
Same remit, four checks before anyone writes an appeal letter.
Read the remit codes
Pull the CARC, RARC and stated reason. In Indiana and Virginia, a missing notice is a compliance gap in itself.
Sort by plan type
Fully insured, self-funded, Medicare Advantage or Medicaid. Only state-regulated plans get the state law argument.
Batch the like claims
Group downcodes with the same reason. Indiana allows batches of similar claims; Virginia allows batches per patient.
Appeal, then escalate
File inside the 180-day window. Pattern of non-compliance goes to the state insurance department.
Two ways to appeal the same 99285 downcode
The laws give you new arguments. They do not replace the clinical record.
Generic appeal
- Template letter that says the level was correct
- No reference to the state statute or notice defects
- One claim at a time, months after the remit
- Final diagnosis argued instead of presenting symptoms
Law-aware appeal
- Cites the state chapter and any missing notice element
- Shows MDM: problems addressed, data reviewed, risk
- Batched with similar claims, inside 180 days
- Presenting symptoms framed under the prudent layperson standard
Is your team ready to use these laws?
Tick what is true for your ED group today.
The 2026 laws do not ban downcoding. They make it slower and more visible on state-regulated plans. ED groups that sort remits by plan type, batch by reason and appeal inside 180 days get the full benefit.
Questions operators ask next
Which states have laws against insurer downcoding?
In 2026, Indiana (IC 27-1-52, effective July 1, 2026), Virginia (amendment to Code 38.2-3407.15, effective July 1, 2026) and Illinois (SB 3114, effective January 1, 2028) enacted downcoding laws. The AMA reports more than a dozen states introduced bills this year. Maryland's insurance regulator separately ordered Cigna to stop E/M downcoding in March 2026.
Can an insurer downcode an ED visit based only on the diagnosis code?
In Indiana, no: the law bars downcoding based solely on the reported diagnosis code. Virginia requires any automated downcode to consider all relevant patient data documented on the claim. Federal No Surprises Act rules at 45 CFR 149.110 also bar plans from deciding what counts as an emergency solely on the basis of diagnosis codes.
How long do I have to appeal a downcoded claim in Indiana or Virginia?
At least 180 days in both states. Indiana requires insurers to allow an appeal window of not less than 180 days and to accept batches of similar claims. Virginia requires at least 180 days after notice of the downcode and says a natural person must decide every downcoding dispute.
Do state downcoding laws apply to self-funded employer plans?
Generally no. Self-funded employer plans are governed by federal ERISA, not state insurance law, so state downcoding statutes usually do not reach them. Medicare Advantage plans are also governed mainly by federal standards. Check the plan type on each remit before citing a state law in an appeal.
