MA31 Remark Code - Missing or Invalid Dates Explanation

The MA31 remark code indicates that there are missing, incomplete, or invalid beginning and ending dates for the period billed. This code supplements an adjustment reason code that has already identified a claim issue, clarifying that the dates specified in the claim do not meet the required criteria.

How It Relates to the Denial

The MA31 remark typically accompanies adjustment reason codes related to claim denials or reductions due to date discrepancies. The combination signals that the claim cannot be processed correctly without valid date information.

Common Scenarios

1A provider submitted a claim for physical therapy services that included an incorrect date range. The remittance returned with an adjustment reason code indicating a denial for insufficient information.
→ The MA31 remark clarifies that the denial is specifically due to the missing or invalid beginning and ending dates of the billing period, which must be corrected for resubmission.
2A hospital billed for inpatient services but did not specify the discharge date on the claim. The payer responded with an adjustment reason code for incomplete information.
→ The MA31 remark highlights that the missing discharge date is the specific issue affecting the claim's processing, necessitating correction before re-filing.
3A claim for a series of outpatient visits was submitted without clear start and end dates. The remittance included a reason code for denial due to lack of detail.
→ The MA31 remark serves to indicate that the lack of complete date information is the reason for the claim's denial, which needs to be addressed to proceed.

What to Do

  1. Review the claim for the correct beginning and ending dates of the service period.
  2. Ensure that the dates are complete and valid according to the payer's requirements.
  3. Correct any discrepancies and prepare the claim for resubmission.

What to Check

  • The original claim submission for the billed dates.
  • Payer guidelines regarding date requirements for the specific service type.
  • Any previous communications from the payer that clarify date expectations.
