Corrected Claim Cover Letter
Use this when the fix is a corrected claim, not an argument — a wrong modifier, a transposed member ID, a diagnosis-pointer error. Sending it as a corrected claim (not a fresh one) prevents a duplicate denial and preserves the original filing date.
What makes it win
- Mark it a corrected claim and reference the original claim number and DOS
- State exactly what changed — the field, the old value, the new value — so it isn't read as a duplicate
- Use the payer's required corrected-claim mechanism (frequency code 7 on the 837, or the payer's form)
- Preserve the original submission date to keep timely filing intact
