ANSI v5010A1 & v5010A2: What are the Differences Between ANSI 5010 ‘Base’ and ‘Errata’ Versions

5010 Base Version
In the final rule published on January 16, 2009, the secretary of DHHS adopted ASC X12N v5010 also known as the ’Base’ version, as the next standard for HIPAA covered transactions.

5010 with Errata
Several errors were identified in the 5010 ’Base’ version of the ANSI transactions that were adopted by the DHHS in January 2009. The Standards Development Organizations have made corrections to the 5010 ’Base’ versions of certain ANSI transactions. As a result, X12N released the ’Errata’ versions, which were adopted by DHHS to replace the ’Base’ versions for HIPAA compliance.

5010A1
5010A1 is new ’Errata’ version for the ANSI ASC X12N 837P Professional Health Care Claim transaction. The ANSI 837P v5010A1 crosswalks to the CMS-1500 claim form.

5010A2
5010A1 is new ’Errata’ version for the ANSI ASC X12N 837I Institutional Health Care Claim transaction. The ANSI 837I v5010A2 crosswalks to the CMS-1450 claim form. Below is a list of the ANSI transactions and version numbers:
