Signature sheet
We keep a master signature sheet where each provider's name, provider #, credential is printed and then s/he signs "as you would sign a note." We assign an internal provider number (just 5 digits), and we ask that providers (MD, DO, PA, NP, etc) both sign and add their number. Even those with terrible writing can manage to legibly include their number.
This allows our chart abstractors to "decipher" the signatures accurately, and also gives us additional "proof" in an audit that this is truly Dr X's signature. (Of course, we are a pediatric practice so have virtually no Medicare patients.)
Hope that helps,
