N748 Remark Code: Related Hospital Charges Not Received

N748 means the payer adjusted this claim because it has not received the related hospital charges. The payer ties this service to a hospital claim and will not finalize it until the hospital's claim is on file.

What N748 means

Some payers process certain claims only in relation to a hospital stay. A professional service during an admission, an ancillary service tied to an inpatient stay, or a transport to or from a hospital may be matched against the hospital’s own claim. N748 tells you the payer looked for that hospital claim and did not find it.

The adjustment is about timing and linkage, not about whether your service was valid. It often appears with CARC 107, which says the related or qualifying claim was not identified.

Common causes

  • The hospital has not yet billed the stay, which can take longer than professional billing.
  • The hospital’s claim was rejected or is in suspense for its own errors.
  • Dates of service or patient identifiers differ between the two claims, preventing a match.
  • The patient was treated at a hospital that billed a different payer.

How to fix it

  1. Confirm the admission or encounter dates and the hospital involved.
  2. Contact the hospital’s billing office to check whether its claim was submitted, and to which payer.
  3. Compare patient identifiers and dates on both claims; correct yours with resubmission code 7 if they are wrong.
  4. Once the hospital’s claim is on file, ask the payer whether it will reprocess your claim automatically or needs a resubmission.
  5. Track the claim against the payer’s timely filing limit while you wait.

How to prevent it

For services that depend on a hospital claim, consider holding your claim briefly or confirming the hospital has billed. Keeping timely filing dates visible prevents a pending N748 from turning into a late-filing denial.

Codes that may appear with N748

  • CO-107 (The related or qualifying claim/service was not identified on this claim.): The related or qualifying claim or service was not identified, which here is the hospital claim.
  • CO-16 (Claim/service lacks information or has submission/billing error(s).): Some payers use the general 'lacks information' code with N748.
  • CO-B15 (This service/procedure requires that a qualifying service/procedure be received and covered.): Requires a qualifying service that was received and covered, a similar dependency rule.
  • N181 (Additional information is required from another provider involved in this service.): Additional information is required from another provider involved in the service.
  • CO-148 (Information from another provider was not provided or was insufficient/incomplete.): Information from another provider was not provided or was insufficient.

N748 FAQ

Why would a payer need the hospital claim first?

Some payers price or validate professional, ancillary, or transfer-related services against the hospital stay. Without the hospital claim, they cannot confirm the stay or apply their rules.

Can I make the hospital submit its claim?

Not directly, but you can contact the hospital's billing office to confirm the claim was submitted and ask when. Share the payer's remark if it helps.

Should I resubmit after the hospital claim is processed?

Ask the payer. Some reprocess linked claims automatically once the hospital claim arrives; others require you to resubmit or request reconsideration.
