M137 Remark Code - Part B Coinsurance Explanation
The M137 remark code indicates that the adjustment being reported relates to Part B coinsurance associated with a demonstration project or pilot program. This means that the billed service was affected by specific coverage rules or payment methodologies under a special initiative, impacting the coinsurance amount due from the patient.
How It Relates to the Denial
The M137 remark code typically accompanies claim adjustment reason codes that reference reductions in payment related to coinsurance. This combination signals that the payer is applying specific adjustments based on participation in a demonstration project or pilot program affecting Part B services.
Common Scenarios
1A provider submitted a claim for a Medicare Part B service and received an adjustment that reduced the payment due to applicable coinsurance.
→ The M137 code clarifies that the reduction is due to coinsurance rules under a demonstration project, which may have different guidelines than standard Medicare coverage.
2A patient received outpatient therapy services, and the remittance shows a decrease in the payment amount with a note regarding coinsurance.
→ Here, the M137 remark indicates that the coinsurance adjustment is specifically tied to a pilot program affecting the outpatient therapy services billed.
3A claim for a diagnostic test under Part B was processed with a coinsurance adjustment noted on the remittance advice.
→ The presence of the M137 remark code suggests that the coinsurance amount was calculated according to the terms of a demonstration project, which may alter typical payment structures.
What to Do

What to Check
