You'll get a little Christmas present from HHH MAC subcontractor National Government Services this month. On Dec. 27, NGS will begin allowing providers to initiate their own adjustments to claims that have been fully or partially denied by automated edits for national coverage determinations (NCDs) or local coverage determinations (LCDs). NGS notes in an e-mail message to providers. Currently, providers have to submit a written request to NGS for the MAC to make the adjustments. Why? "Most claims that are denied for reason codes 55A00, 52NCD, 53NCD, or 54NCD involve a diagnosis that meets the requirements of the NCD or LCD and that is appropriately documented in the provider's records," NGS explains. "However, the diagnosis code has been omitted from the claim." The new process will improve efficiency, the MAC says. NGS will allow provider-initiated adjustment when a 55A00, 52NCD, 53NCD, or 54NCD claim or line item has been denied without medical review. "That is, no additional documentation request (ADR) was sent to you and no documentation was submitted," the MAC explains. Instructions: You should submit adjustments with claim change reason condition code D1, "changes to charges," NGS instructs. Enter the appropriate corrections to the diagnosis or other codes that resulted in the LCD/NCD denial, covered charges for the line item(s) involved, and adjustment reason code "LN" (Provider adjustment to correct LCD/NCD error).
