The Denied Claim and the Missing Modifier
A claim for an office visit (established patient, moderate complexity) was submitted with an E/M code and a separate procedure code for a minor skin lesion removal performed the same day. The payer denies the E/M as 'included in the procedure.' The physician documented that the decision to remove the lesion and the E/M work were separate and that a distinct problem was addressed, but the coder did not append modifier 25 to the E/M code. The claim is now 20 days past the filing deadline for appeals in the payer's contract, though the practice's internal policy says appeals should be filed within 30 days. The patient has already received a statement showing the E/M balance as patient responsibility. The office manager asks you, the billing MA, to 'just rebill it and hope it goes through.'
1. What is the correct sequence of actions, and why is 'just rebill it' the wrong first move?

'Just rebill it' is wrong because resubmitting the same claim without addressing the denial reason invites another denial and may look like duplicate billing. The correct sequence:
- Verify the documentation supports a separate E/M service and that modifier 25 is appropriate. If it is, the fix is a corrected claim with modifier 25, not a blind rebill.
- Check the appeal/corrected-claim deadline. The contract deadline (20 days past) and the internal policy (30 days) conflict. Determine which governs and whether a corrected claim is treated differently from an appeal. If the contract deadline has passed, a corrected claim may still be accepted, but do not assume it.
- Contact the payer to confirm whether a corrected claim can be filed and what documentation is required.
- Hold the patient statement - do not pursue patient responsibility for a balance that is under active correction.
- Document every step and the outcome.
The rebill may ultimately be part of the fix, but only after confirming the modifier is supported and the filing path is valid.
2. The payer confirms the corrected claim window is still open but requires supporting documentation. What do you send, and how do you handle the patient's statement?

Send:
- The corrected claim with modifier 25 appended to the E/M code.
- The physician's progress note showing the separate E/M work and the distinct problem addressed.
- The procedure note for the lesion removal.
- A brief cover letter or appeal narrative explaining the denial reason and why the E/M was separate.
Patient statement: place a hold on the E/M balance and notify the patient in writing that the balance is under review and no payment is due while the claim is corrected. Do not collect on a balance that may be reversed. If the correction is denied and the balance is ultimately patient responsibility, resume normal billing at that point with a clear explanation.
Document the hold, the date, and the reason so the account is not sent to collections in error.
