The New Hampshire Memo of Permanent Impairment Award is an official document issued by the New Hampshire Division of Workers' Compensation in order to document a worker's permanent impairment due to a work-related injury or illness. This document provides an estimate of the worker's impairment rating, which is used to determine the amount of compensation the worker may receive as a result of the injury or illness. There are three types of New Hampshire Memo of Permanent Impairment Award: medical, functional, and vocational. The medical impairment award is based on the worker's medical condition and potential for recovery. The functional impairment award is determined by the worker's ability to perform activities of daily living. The vocational impairment award is based on the worker's ability to return to the same or similar job as before the injury or illness.
