Difference Between 837P and 837I
837P is the electronic equivalent of CMS-1500 used by private practices, physicians, and allied health. 837I is the electronic version of UB-04 used by inpatient hospitals, skilled nursing, and ambulatory surgical centers.
What is a 277CA Claim Acknowledgment?
The 277CA is returned by clearinghouses within hours of 837 transmission. An acceptance status code of A1 indicates the claim has entered payer adjudication; an A3 code indicates fatal syntax rejection.
