RARC N517: Resubmit a New Claim With the Requested Information
This remark is an instruction, not a denial reason on its own: the payer wants the provider to submit a brand-new claim that incorporates the specific information the payer previously requested, rather than simply correcting and resending the original claim.
What Does RARC N517 Mean?
N517 shows up when a payer has already asked for additional information — records, an itemized statement, a coordination-of-benefits update, a corrected identifier, or similar supporting documentation — and is now directing the provider to build a fresh claim that includes that information, rather than treating a follow-up submission as a correction to the original claim. It typically pairs with a CARC that reflects the claim being closed out or adjusted to zero pending the new submission, signaling that the payer's system does not expect the original claim number to be reopened; a new claim is the expected path forward.
This distinction matters procedurally: some payers process 'corrected claims' against the original claim number with a corrected-claim bill type or frequency code, while N517 tells the biller the payer wants a wholly new claim submission carrying the previously requested information, not a correction tied back to the original. Submitting a correction instead of a new claim in this scenario can result in the resubmission being rejected or ignored, effectively resetting the cycle.
Because N517 is about the format and completeness of the resubmission rather than about whether a deadline was missed, it can appear even when the original request for information was answered promptly elsewhere (e.g., by phone or fax) if that response didn't make it into a new claim submission the payer's system recognizes.
What to Do
Locate the original request for information — often a prior remittance remark, an ADR (additional documentation request) letter, or a payer portal notice — and confirm exactly what was asked for. Assemble that information (medical records, itemized charges, other-insurance details, corrected patient or provider identifiers, etc.) and prepare it to accompany a new claim rather than a corrected-claim resubmission of the original.
Submit the new claim through the payer's standard intake channel, attaching or referencing the requested information as the payer's submission guidelines specify. Track the new claim separately from the original, since the original may show as closed or zero-paid in the payer's system and will not be reopened by further correspondence alone.
Common Scenarios
- A payer requests medical records to support medical necessity, and after the provider replies with only the records (without a new claim form), the payer returns N517 indicating a full new claim submission including those records is required.
- A claim is closed pending coordination-of-benefits information; once the correct other-insurance details are obtained, the biller must file a new claim carrying that information rather than expecting the original claim to reprocess automatically.
- An itemized bill was requested for a high-dollar facility claim, and the provider's fax response wasn't linked to a new claim submission, prompting N517 on the remittance.
- A claim lacking a required attachment (e.g., an operative report) is closed, and the biller resubmits it as a new claim with the operative report attached, per the N517 instruction, instead of sending a corrected-claim frequency code.
