Question: One of our physicians likes to sign everything with just his initials, or sometimes an illegible scrawl. Do we need some type of documentation to support what an auditor might not be able to read?
Answer: Yes, you would be wise to keep a signature log as additional documentation.
What it is: Medicare requires that the professional who orders or provides services authenticate the services. The documentation must contain either “a legible handwritten, full signature with credentials, handwritten initials over a typed or printed name, or electronic signature,” according to information from National Government Services (NGS). Otherwise, the payer could deny your claim. Medicare defines a handwritten signature as “a mark or sign by an individual on a document to signify knowledge, approval, acceptance, or obligation,” according to bulletin MM6698.
If the chart includes an illegible signature or the provider’s initials instead of a full signature, you might need to include a signature log in documentation for the payer. The log identifies the provider associated with the service. You can include the log on the page with the initials or illegible signature or as a separate document. “Reviewers will consider all submitted signature logs regardless of the date they were created,” states MLN Matters bulletin MM6698, implemented April 16, 2010.
