Summary
The claim is not denied. The payment arrives. The EOB shows a paid amount. What it does not show is that the plan's adjudication system downgraded your 99214 to a 99213 before posting, taking $42 to $74 off a chronic disease management visit.
For a family physician seeing 18 to 22 established patients a day, that compounds to $28,000 to $74,000 a year. It never appears on your denial dashboard, because it is not a denial.1
Documentation that carries the Medical Decision Making, attached at the point the decision was made.
Book a demoWhat it is
A denial is visible. You get a CARC, someone works it, you appeal or you correct. A downcode is not a denial. The claim adjudicates, the money lands, and the amount is one level lower than what you submitted, with nothing flagged.
Reported exposure runs by plan.11Reported MA downcoding exposure by plan, per physician per year. UnitedHealthcare Community Plan $22,000 to $38,000, Humana Gold Plus $16,000 to $28,000, Aetna Medicare Advantage $14,000 to $24,000, Devoted Health $10,000 to $18,000.

A practice losing money this way does not see it in the denial report. It sees a net collection rate drifting down quarter on quarter with no visible cause.
How to find it in your own data
Run a submitted-versus-paid E/M variance report filtered by MA payer. If UnitedHealthcare, Humana or Aetna are consistently paying one level below what you submitted, it is active.
Then check 99215 utilisation by provider. The family practice benchmark is 22 to 28 percent of established visits.55Family practice benchmark for 99215 utilisation is 22 to 28 percent of established visits. Below 18 percent indicates undercoding or payer downcoding on legitimately coded encounters. Below 18 percent means either you are undercoding or the payer is downcoding claims you coded correctly, and the variance report tells you which.
Appeal windows run 60 to 180 days from remittance. Practices that have never filed structured appeals on downcoded claims are reported to recover $18,000 to $52,000 per physician within 90 days.44MA appeal windows typically run 60 to 180 days from remittance. Structured appeals on previously downcoded claims are reported to return $18,000 to $52,000 per physician within 90 days for practices that have not been filing them. That is money already earned, sitting inside the window, waiting for somebody to ask.
Why documentation decides it
The 2026 E/M rules put Medical Decision Making at the centre of level selection. Number and complexity of problems, amount and complexity of data reviewed, risk of complications. A 99214 stands or falls on whether the note evidences those three.
An adjudication system reading a thin note will downgrade it, and it will be right to. The defence against a downcode is not an appeal. It is a note that carried the MDM in the first place, written at the time, by someone who was in the room.
Separately, AAPC puts undercoding at up to 19 percent of E/M visits nationwide, at roughly $37 each.22AAPC Audit Services reports up to 19 percent of E/M visits are undercoded nationwide, each costing roughly $37 or more in lost Medicare reimbursement per encounter. That is your own coding, not the payer's. And the 2026 conversion factor of about $32.35 per RVU already took $5 to $6 off every 99214, which at 350 to 500 E/M visits a month is $21,000 to $36,000 per physician per year that is structural and does not come back.332026 Medicare Physician Fee Schedule conversion factor is approximately $32.35 per RVU, reducing payment by roughly $5 to $6 per 99214 encounter. At 350 to 500 E/M visits per month that is roughly $21,000 to $36,000 per physician per year, structural and non-recoverable.
Where WA\ comes in
WA\ Clinician drafts the note against the MDM criteria and attaches the coding at the point the decision was made, with the problems, the data reviewed and the risk stated because they happened, not because someone remembered them at seven in the evening.
WA\ Admin runs eligibility before the visit and works the claim after it, on the same record. The submitted-versus-paid variance is visible because both halves are in one place.
The arithmetic
Take the middle of the reported range. One family physician, $50,000 a year of silent downcoding, plus $37 on 19 percent of E/M visits, against a subscription on our pricing page.
The ambient AI category has spent three years competing on note-writing speed, where the best randomised result ever measured is 41 seconds a visit. The downcode is roughly a thousand times larger and nobody in this category writes about it.
What we are not claiming
We are not a revenue cycle management company and we do not replace one. If you have a good RCM partner filing structured appeals, keep them, and the numbers above are their argument as much as ours.
The plan-level figures are third-party analysis across 180 family practice groups, not our data, and your payer mix and specialty will move them. Run the variance report on your own remittances before you believe anyone, including us.
Availability
WA\ Admin runs as a 90-day pilot reporting revenue, hours saved and patients cared for. Ask us to include submitted-versus-paid E/M variance in the report. Pricing is on one page.
Frequently asked questions
What is Medicare Advantage downcoding?
A payer adjudication system reducing your E/M level before paying, without issuing a denial. You submit a 99214, the plan pays a 99213, and the remittance shows a paid amount on a clean claim. Nothing flags it. Reported exposure runs $42 to $74 per chronic disease management visit and $28,000 to $74,000 per family physician per year, with UnitedHealthcare Community Plan at $22,000 to $38,000, Humana Gold Plus at $16,000 to $28,000 and Aetna Medicare Advantage at $14,000 to $24,000. It does not appear on a denial dashboard because it is not a denial.
How do I know if my practice is being downcoded?
Run a submitted-versus-paid E/M code variance report filtered by Medicare Advantage payer. If UnitedHealthcare, Humana or Aetna are consistently paying one level below what you submitted, downcoding is active. Then check 99215 utilisation per provider against the family practice benchmark of 22 to 28 percent of established visits. Below 18 percent indicates either undercoding on your side or payer downcoding on legitimately coded encounters, and the variance report distinguishes them. The other signal is a net collection rate drifting down with a steady denial rate.
Can I appeal a downcoded claim?
Yes, within the window. Medicare Advantage appeal windows typically run 60 to 180 days from remittance. Structured batch appeals on previously downcoded claims are reported to return $18,000 to $52,000 per physician within 90 days for practices that have never filed them, representing 12 to 24 months of suppressed revenue that is still recoverable. The longer-term fix is documentation. From 2026 E/M level selection turns on Medical Decision Making, and a note that does not evidence the problems, the data reviewed and the risk will be downgraded correctly.
Run the variance report.
Ask us to include submitted-versus-paid E/M variance in your 90-day pilot report. If the number is flat, you have lost a quarter and nothing else.
