Reopenings for Minor Errors and Omissions

A clerical error/omission reopening is an action taken to change an initial determination to correct minor errors or omissions outside of the Medicare appeal process.

  • Clerical error/omission reopenings are considered “preredeterminations”
  • All reopenings are granted at the discretion of the contractor
  • A contractor’s refusal to reopen is not appealable; however, a party may request to appeal the initial determination—but must do so within the 120-day timeframe

What is a Clerical Error?

A clerical error is defined as a human or mechanical error on the part of the party, such as:

  • Mathematical or computational mistake
  • Transposed procedure or diagnostic codes
  • Inaccurate data entry
  • Computer errors
  • Incorrect data items

Clerical errors do not include omissions or failure to bill for items or services. Third party payer errors do not constitute clerical errors.

National Government Services encourages providers to initiate electronic adjustments to correct errors or omissions on processed claims, which contain line items denied by automated LCD/NCD edits.

If an electronic adjustment cannot be made (i.e., when the claim has been denied in full) an electronic or written reopening request may be submitted to facilitate the clerical error/omission reopening request process.
