Documented attestation mistakes to avoid

Last reviewed October 26, 2026

The requirement is young, but its design points at the mistakes worth avoiding. Each one is a way to end up with a signed statement the file cannot support.

Graphic of four attestation mistakes to avoid

The first is treating the affirmation as boilerplate - pasting the language in because the schema requires the element, without a review that would back it. The element exists so that a person thinks before the file posts; automation that fills it in silently defeats it.

The second is a name without an owner. Encoding a title instead of a person, leaving a departed executive's name in the file, or designating someone who has never heard of the machine-readable file all fail the same test: no one actually stands behind the statement.

The third is attesting over unexamined data. The affirmation covers completeness and derivability, not just format. A file can pass the CMS validator and still lack the fee-schedule detail a percentage charge needs - the statement covers what the validator cannot see.

The fourth is forgetting the refresh. Every reposted file re-makes the statement as of its new date, whether anyone reviewed the data or not.
