When there is a conflict between CMS' Internet Only Manuals (IOMs) and federal regulations, which provisions take precedence?

• A. The IOMs
• B. Whichever is more lenient
• C. Whichever is stricter
• D. Regulatory Provisions

Answer: (D)

The binding authority comes from the actual regulations. CMS Internet Only Manuals are policy guidance that explain how to implement the law and how CMS intends to apply rules; they’re helpful for understanding process and practice. But they don’t create enforceable requirements that can override what the regulations say. When a conflict arises, the regulatory provisions—those required by the Code of Federal Regulations and related statutes—control and dictate what must be done. CMS will align its manuals with those regulations, but the regulation text itself remains the source of enforceable requirements. In practice, if a regulation says one thing and an IOM seems to permit another, follow the regulation.
