ANSI X12 837P - 4010 2310A PRV - Referring Provider Specialty Information

Image Description

September 08, 2025

The PRV (Provider Information) segment in the 2310A loop of the X12 837 (4010) professional claim is used to convey the referring provider’s specialty or taxonomy code. This allows the payer to understand the referring provider’s qualifications, which may impact coverage, referral requirements, or claim adjudication.

The PRV segment is situational. It should only be included when the payer requires the referring provider’s taxonomy code to be explicitly sent. Some payers use this information to validate referral rules, ensure proper specialty routing, or confirm benefit eligibility.
