Implementation Guides
You must comply with the ASC X12N Implementation Guides.
ASC X12 writes these guides for all health benefit payers, not specifically for Medicare. Each guide offers specific technical instructions for carrying out HIPAA standards, including instructions on content and format requirements.
The Health Care Claim: Institutional Implementation Guide is available from X12 by purchasing an X12 License. Visit the X12 Licensing Program webpage to learn more.
