M18Remark Code (RARC)Active
M18 Remark Code - Home Use Eligibility Explained
The M18 remark code indicates that certain services billed may be eligible for home use, but the payer clarifies that services provided in a hospital or Skilled Nursing Facility (SNF) do not meet this home-use criterion. This remark supplements an adjustment reason code that explains the denial or reduction of payment based on the location where services were rendered.
How It Relates to the Denial
The M18 remark code typically accompanies adjustment reason codes related to service location, particularly when a service is denied based on it being performed in a facility rather than a home setting. The combination signals that the payer is enforcing guidelines about where specific services can be billed as home-use.
Common Scenarios
1A patient received physical therapy services while admitted to a Skilled Nursing Facility and the claim was submitted for those services.
→ The M18 remark indicates that the payer is denying or reducing payment because the services performed are not considered home-use, as they were provided in a SNF.
2A claim for home health nursing services is submitted, but the service was actually provided in a hospital setting.
→ The M18 remark points out that the payer will not reimburse for these services since they were not delivered in the patient's home, contradicting the guidelines for home-use eligibility.
3A claim for durable medical equipment (DME) is submitted for a patient in a hospital, but the equipment is typically approved for home use.
→ The M18 remark serves to clarify that although the equipment is home-use eligible, the payment is denied because it was provided in a hospital, not in a home setting.
What to Do
- Review the accompanying adjustment reason code to understand the primary reason for denial or adjustment.
- Consider resubmitting the claim with the appropriate documentation if the service was indeed provided in a home setting and not in a facility.
What to Check
- Verify the patient's discharge status to confirm if they were in a hospital or SNF when the service was provided.
- Check the payer's guidelines regarding home-use eligibility for the specific services billed.
- Review the claim submission details to ensure the correct place of service code was used.
