Referring Provider Information
Effective July 1, 2004, anesthesia providers must submit the UPIN number of the referring surgeon/physician on the claim. If you file hard copy, the UPIN number should be populated in block 1 7a of the CMS 1500 claim form. For those who file electronically, you should submit the referring surgeon/physician’s UPIN number. This is necessary for proper claims processing.
Anesthesiologists should use OTH000” as the referring or attending UPIN number for providers who are not assigned a UPIN number by Medicare. For example, when providing anesthesia services for recipients who are being treated by dental providers, please use OTH000” as the UPIN number in block 1 7a of the CMS 1500 form. Use OTH000” and the ID qualifier 1 G when filing claims electronically. As a reminder, claims for anesthesia providers not containing this information will deny.
