Write-off (contractual adjustment)

Not all write-offs are created equal, and conflating them is one of the most common financial reporting errors in medical billing. Contractual adjustments are expected and normal. Bad debt write-offs after exhausting collection effort are unfortunate but legitimate. Administrative or discretionary write-offs made without proper authorization are where revenue leakage hides and where compliance exposure begins.

The danger with miscoded write-offs is that they make your net collection rate look artificially high. If a billing team writes off an underpayment as a contractual adjustment rather than working the appeal, the dollars disappear from AR without ever appearing as a denial or a rework item. Management never sees it. Over hundreds of claims, this can amount to significant undetected revenue loss.

Write-off authority should be tiered and documented. Contractual adjustments can be automated based on payer fee schedules. Bad debt write-offs above a threshold should require supervisor approval. Discretionary write-offs should require both a clinical or administrative justification and sign-off from practice leadership. Practices without clear write-off authorization policies are at risk of both revenue leakage and compliance problems.
