M100 Remark Code - Oral Anti-Emetic Drug Coverage
The M100 remark code indicates that the payer will not cover the cost of an oral anti-emetic drug unless it is administered immediately before, at, or within 48 hours of a covered chemotherapy drug. This remark supplements an adjustment already detailed by a Claim Adjustment Reason Code, providing clarity on the conditions for coverage of the anti-emetic drug.
How It Relates to the Denial
The M100 remark typically accompanies adjustment reason codes related to denied claims for oral anti-emetic drugs. It signals that the claim is being denied due to the timing of administration relative to chemotherapy treatment.
Common Scenarios
1A claim was submitted for an oral anti-emetic drug prescribed for nausea, but the administration date does not coincide with chemotherapy treatment.
→ The M100 remark indicates that the payer expects the oral anti-emetic drug to have been administered in a timely manner concerning chemotherapy, which was not the case here.
2A patient received an oral anti-emetic drug a week after their chemotherapy session, and the claim was denied.
→ In this situation, the M100 remark clarifies that the payer's policy requires the anti-emetic to be administered within 48 hours of chemotherapy for coverage, hence the denial.
3A provider billed for an oral anti-emetic drug given to a patient who was not undergoing chemotherapy at the time of administration.
→ The M100 remark points out that the payer does not cover this drug if it is not linked to the chemotherapy treatment, reflecting the specific coverage criteria.
What to Do
- Review the administration dates of the oral anti-emetic drug in relation to chemotherapy treatment dates.
- Ensure that future claims for oral anti-emetic drugs include documentation of administration timing per payer guidelines.
- If appropriate, resubmit the claim with corrected dates or additional information supporting the administration timing.
What to Check
- The patient's treatment records to confirm the administration date of the anti-emetic drug.
- The chemotherapy administration record to determine the timing of the chemotherapy drug.
- The payer's policy documents regarding coverage of anti-emetic drugs and related requirements.
