Companion Guides
The following documents are companion guides to the National Electronic Data Interchange Transaction Set Implementation Guides, ASC X12N. They are intended for vendors that design software or systems for submitting health care transactions electronically to Arkansas Medicaid. These documents supplement but do not supersede requirements outlined in the ASC X12N implementation guides.
The Health Insurance Portability and Accountability Act (HIPAA) requires Arkansas Medicaid and other covered entities to comply with the electronic data interchange standards for health care as established by the Secretary of Health and Human Services. The ASC X12N implementation guides were established as the standards of compliance. These companion guides provide the supplemental requirements specific to Arkansas Medicaid, as permitted within the transaction sets. The transactions described in these guides are compliant with ACA 1104 standards.
To develop and test a system for Arkansas Medicaid transactions, follow both the applicable implementation guide and its companion guide.
