The payer playbook has shifted. Where claims used to deny – creating a work queue and an appeal – they increasingly pay at a reduced amount instead. Reductions generate no queue, no appeal deadline, and no visibility. This guide covers the three silent repricing mechanisms hitting physician groups in 2026.

Algorithmic E/M Downcoding

Several national commercial payers run claim-level algorithms that reprice high-level E/M codes downward at adjudication when diagnosis codes allegedly do not support the level. The remit shows a payment, often without a distinct remark code. Detection: compare billed level to paid level, line by line, by payer. When the record supports the level, these overturn at high rates – and a consistent pattern justifies a payer-level dispute with documentation, not claim-by-claim rework.

Modifier 25 Reductions

Same-day E/M with a minor procedure used to deny outright; a growing number of plans now pay the E/M at 50-75% of allowable. Multiplied across dermatology, orthopedics, cardiology and primary care volume, the aggregate is large and the individual instance invisible. The detection report compares paid amounts on modifier-25 E/M lines against the same codes without a same-day procedure, by payer.

CO-45: Underpayment Dressed as Contractual Adjustment

When a payer pays below the contracted rate, most practice management systems post the difference as a CO-45 contractual adjustment – exactly as if it were the legitimate discount – and close the claim as paid in full. If the PM system contract loads are stale, systematic underpayment auto-writes-off silently for as long as the load stays stale. The test: sample one month of remits for the top three payers and compare actual allowed amounts against loaded contract rates, line by line.

The Common Defense

All three mechanisms defeat denial-based management. The defense is the same in each case: line-level comparison of paid versus expected, by payer, on a schedule. Groups that run expected-versus-paid variance reporting catch silent repricing in weeks; groups that manage by denial rate never see it at all.
