Which statement about OMAHA's status is true?

• A. It can be modified freely
• B. It must be used as published
• C. It is restricted by copyright
• D. It is not widely used

Answer: (B)

OMAHA is a published, licensed resource whose content—definitions, codes, and manuals—are maintained in official releases. Implementing the system means using the exact published version and applying updates only when released by the publishers. This preserves consistency and comparability of data across different settings, which is essential for meaningful analysis and interoperability. Modifying the official content without authorization would break standardization, and the system is widely used, not restricted to a small niche.
