RARC N710: Required Clinical Notes or Documentation Missing

What Does RARC N710 Mean?

RARC N710 indicates that the payer needs clinical notes or supporting documentation to adjudicate the claim, and these were not included with the submission. The specific documentation required varies by payer and service type but may include progress notes, treatment plans, diagnostic test results, therapy notes, or other clinical records that support the medical necessity and appropriateness of the billed services.

Payers request documentation for various reasons. High-cost services, services requiring prior authorization, services billed with unusual modifiers or diagnosis combinations, and claims selected for prepayment review all commonly require attached clinical records. Some payer contracts or coverage policies mandate documentation submission for certain procedure codes as a standard requirement.

N710 differs from other documentation-related RARC codes (such as N712 for summary documents or N714 for reports) in that it specifically refers to clinical notes — the day-to-day records of patient care that document what was done, why it was done, and how the patient responded.

What to Do

Review the payer's remittance advice or claim status inquiry to identify what specific documentation is required. If the remittance does not specify, contact the payer's claims department to clarify exactly which clinical notes are needed. Pull the relevant documentation from the patient's medical record — this may include encounter notes, procedure notes, therapy logs, or diagnostic results from the date of service.

Attach the documentation to the claim following the payer's submission guidelines. For electronic submissions, this typically means using the 275 Additional Information transaction or the payer's electronic attachment portal. For paper submissions, include a cover letter referencing the claim number and N710. Resubmit the claim with the attached documentation and track it to confirm receipt and processing.

Common Scenarios

• A claim for a high-cost injectable medication is denied because the payer requires clinical notes documenting the medical necessity and prior treatment failures
• A prepayment review selects a claim for documentation audit, and the provider did not submit the required clinical notes with the original submission
• Therapy claims require progress notes demonstrating functional improvement, and the notes were not attached when the claims were submitted
• A prior authorization was obtained but the payer's approval letter specified that clinical notes must accompany the claim, which were not included
