HIPAA / EDI Publications



We have completed the development of applications and processes that comply with ACA mandated CAQH CORE operating rules for Phase I, II and III. IT has also completed testing with the CAQH approved testing vendor Edifecs to make sure the solutions are compliant with the CORE requirements and we are currently in the process of obtaining certification (CORE Seals) from CAQH for all the three phases.

      • Phase - I - Operating rules for exchanging batch and real time 270/271 eligibility request and response transactions
      • Phase - II - Operating rules for exchanging 276/277 claims status request and response transactions
      • Phase - III - Operating rules for enrolling and exchanging ERA (835) / EFT transactions
