What N74 means

N74 is a date-structure instruction. The payer received a claim whose service dates crossed from one calendar month into another, and its rules require each claim to stay within a single month. Common for long-term care, home and community-based services, behavioral health programs, and other recurring services, especially under Medicaid.

N74 most often appears with CARC 267 (claim spans multiple months).

Common causes

  • Billing cycles ran on a schedule other than calendar months, such as every four weeks.
  • A single claim covered an entire episode that crossed months.
  • Late charges were added to an earlier claim, extending it into the next month.
  • The payer’s rule was new or not known to billing staff.

How to fix it

  1. Divide the services by calendar month based on dates of service.
  2. Build one claim per month, carrying over diagnoses, authorization numbers, and any monthly amounts such as patient liability.
  3. Recalculate units and charges for each claim based on the dates it covers.
  4. Submit the claims as new claims, keeping the denial on file to show your original submission date.

How to prevent it

Set your billing cycle for affected payers to calendar months and configure your system to cut claims at month-end automatically. Review recurring-service claims before release when an episode crosses a month boundary.

N74 FAQ

Why do payers want one month per claim?

Monthly benefit limits, monthly patient liability amounts, eligibility that changes by month, and monthly rate structures are all easier to apply when each claim stays within a month.

What about a service that runs from the 15th to the 15th?

Split it at the month boundary: one claim through the last day of the first month and another from the first day of the next month. Check whether the service code allows partial-month billing.

Are these new claims or corrected claims?

Usually new claims, since the original could not be processed. Follow the payer's instructions if it asks you to void the original first.
