Modifier 25 Request on a Denied Office Visit
A patient has a 6-mm sebaceous cyst excised in the office on March 4. The provider documented a problem-focused history and exam for the cyst and a separate 10-minute discussion of the patient's new hypertension medication, with a plan to increase lisinopril. The claim billed the excision (CPT 11402) and an office visit (99213) with no modifier. The payer denied the office visit as 'included in the procedure.' The patient's plan has a $2,000 deductible, of which $1,450 is met; the EOB lists the excision allowed amount as $210 and the office visit as $0 patient responsibility. The patient calls saying she was told the visit would be covered and asks the biller to 'just add the modifier so insurance pays.' The practice's compliance officer requires a documentation review before any corrected claim. The filing deadline is 90 days from the date of service, and today is April 20.
1. Should the biller add modifier 25 to the office visit? Explain the decision process.
Read the worked answer
Modifier 25 may be appropriate only if the office visit was a significant, separately identifiable evaluation and management service above and beyond the procedure. The note documents a separate hypertension discussion and a medication change, which is not part of the cyst excision, so the coder should review the full note and, if supported, append modifier 25 to the 99213 and submit a corrected claim. The modifier is not a payment tool; adding it solely because the payer denied the claim would be improper. The corrected claim must be filed within the 90-day deadline, and April 20 is still within that window. Document the review and the rationale. If the visit is not separately documented, do not add the modifier.
2. If the corrected claim is paid, what should the patient be told about financial responsibility?

Explain that the deductible is $1,450 met out of $2,000, leaving $550. If the corrected claim pays the office-visit allowed amount, the patient may owe part or all of that allowed amount until the deductible is met. The excision's $210 allowed amount may also apply to the deductible. The EOB is not a final bill, so provide an estimate after adjudication and offer a payment plan. Check whether the patient has secondary coverage. Do not routinely waive the deductible or copay; doing so can violate payer contracts and anti-kickback rules. Document the estimate, the payment options, and the patient's response.
3. The payer denies the corrected claim as a duplicate. What should the biller do next?
Read the worked answer
Verify the claim status with the payer and confirm whether the corrected claim was received. Use the appropriate resubmission code, such as 7, and the correct frequency code if the payer requires them. Attach the documentation the payer requests and keep all reference numbers. If the corrected claim was timely and properly submitted, request an appeal and explain why the claim is not a duplicate. Do not resubmit identical claims repeatedly, because that can create more duplicate denials. Document each contact, the payer's instructions, and the final outcome.
