N62 Remark Code: Dates Span Multiple Rate Periods

N62 means the dates of service on the claim span more than one rate period, so the payer cannot price the claim as submitted. It asks you to resubmit separate claims, each within a single rate period.

What N62 means

Many facility and program payments use rates that change over time: per diem rates for nursing facilities, rates for home and community-based services, or contracted rates that update on a set date. When a single claim covers dates on both sides of a rate change, some payers’ systems cannot apply two rates at once. N62 is the payer asking you to split the claim at the rate change.

N62 commonly pairs with CARC 16. When the rate change coincides with a new month or year, CARC 267 or CARC 268 may also appear.

Common causes

  • The payer updated rates on a date that fell within the claim’s statement period.
  • Your contract renewed with a new rate partway through the billing cycle.
  • The facility’s rate changed because of a level-of-care or case mix update.
  • The billing cycle does not align with the payer’s rate period calendar.

How to fix it

  1. Find the rate change date from the payer’s rate notice or contract.
  2. Split the claim into two: one ending the day before the change and one starting on the change date.
  3. Allocate services, units, and charges to the correct claim based on dates.
  4. Include required fields on each claim, such as authorization numbers and patient liability amounts, and adjust them if they differ by period.
  5. Submit both as new claims unless the payer’s instructions say otherwise.

How to prevent it

Keep a calendar of rate change dates for each payer and program, and configure your billing system to cut claims at those dates automatically. Review claims for recurring services before release when a rate change is near.

Codes that may appear with N62

N62 FAQ

What is a rate period?

It is the date range during which a particular payment rate applies. Facilities paid per diem or by other rate-based methods may have rates that change at fiscal year boundaries, contract renewals, or when a program updates its rates.

How do I find the rate period boundaries?

Check your contract, rate letters from the payer, or the program's published rate updates. If the boundary is unclear, ask the payer for the effective date of the new rate.

Do I need a new authorization for the second claim?

Not usually, if the original authorization covers all the dates. But make sure the authorization number is on both claims.
