90- 351 C.M.R. ch. 16, § 3
The Workers' Compensation Board will release no individual identification information contained in individual injured workers files to individuals that do not meet the need-to-know standard in Section 2. Individual identifying information includes name, Social Security number, claim, or employee number. If the request is made in person or over the telephone, and the individual is unknown to staff or the need-to-know is not established, a written request will be required. The written request shall state the relationship of the requesting party to the case, the specific information requested, and any other information the party believes helpful in establishing "need-to-know" as defined by these regulations. The written request shall become part of the individual file.
