  Code	Display	Definition
  1.2.840.10065.1.12.1.1	Author's Signature	the signature of the primary or sole author of a health information document. There can be only one primary author of a health information document.
  1.2.840.10065.1.12.1.3	Co-participant's Signature	the signature of an individual who is a participant in the health information document but is not an author or coauthor. (Example a surgeon who is required by institutional, regulatory, or legal rules to sign an operative report, but who was not involved in the authorship of that report.)
  1.2.840.10065.1.12.1.5	Verification Signature	a signature verifying the information contained in a document. (Example a physician is required to countersign a verbal order that has previously been recorded in the medical record by a registered nurse who has carried out the verbal order.)
  1.2.840.10065.1.12.1.7	Consent Signature	the signature of an individual consenting to what is described in a health information document.
  1.2.840.10065.1.12.1.9	Event Witness Signature	the signature of a witness to an event. (Example the witness has observed a procedure and is attesting to this fact.)
  1.2.840.10065.1.12.1.11	Consent Witness Signature	the signature of an individual who has witnessed the health care provider counselling a patient.
  1.2.840.10065.1.12.1.13	Review Signature	the signature of a person, device, or algorithm that has reviewed or filtered data for inclusion into the patient record. ( Examples: (1) a medical records clerk who scans a document for inclusion in the medical record, enters header information, or catalogues and classifies the data, or a combination thereof; (2) a gateway that receives data from another computer system and interprets that data or changes its format, or both, before entering it into the patient record.)
  1.2.840.10065.1.12.1.15	Addendum Signature	the signature on a new amended document of an individual who has corrected, edited, or amended an original health information document. An addendum signature can either be a signature type or a signature sub-type (see 8.1). Any document with an addendum signature shall have a companion document that is the original document with its original, unaltered content, and original signatures. The original document shall be referenced via an attribute in the new document, which contains, for example, the digest of the old document. Whether the original, unaltered, document is always displayed with the addended document is a local matter, but the original, unaltered, document must remain as part of the patient record and be retrievable on demand.
  1.2.840.10065.1.12.1.17	Administrative (Error/Edit) Signature	the signature of an individual who is certifying that the document is invalidated by an error(s), or is placed in the wrong chart. An administrative (error/edit) signature must include an addendum to the document and therefore shall have an addendum signature sub-type (see 8.1). This signature is reserved for the highest health information system administrative classification, since it is a statement that the entire document is invalidated by the error and that the document should no longer be used for patient care, although for legal reasons the document must remain part of the permanent patient record.
