Where this comes up
Providers meet this term in the chart and at the post-visit review — encounter notes, problem lists, medication reconciliation, signed orders, and the time/elements that defend the billed code. If documentation does not support the code, the code does not survive an audit.

What it is in practice
The CMS Signature Requirements fact sheet requires legible identifier with credentials. Stamped signatures are generally not acceptable. Missing signatures can be cured via a Signature Attestation Statement.
How it shows up in your practice
Set the EHR to lock notes after signing. Use a written attestation process for legacy unsigned notes when an audit requires them.
