Accession number

What is Accession number?

Accession number meaning A unique number assigned to the patient by the registrar, indicating the year in which the patient was first seen at the reporting institution and the sequential order in which the patient was identified by the registry or abstracted into the database. The accession number is used for all additional primaries the patient may develop, regardless of the year in which subsequent reportable tumors occur.
