Classification

Denial class: bundling / coding edits

Appealability verdict

Appealable — bundling / coding edits

What to know

These turn on the payer's own edit rules: the NCCI Policy Manual and modifier indicators often support separate payment as billed. The appeal argues the edit was misapplied — no code changes are involved.
