Mass immunization center

Location where providers administer pneumococcal pneumonia and influenza virus vaccination and submit these services as electronic media claims or paper claims or use the roster billing method. This generally takes place in a mass immunization setting such as a public health center, pharmacy, or mall but may include a physician’s office setting.

master patient index (MPI)

File for a facility’s patients that contains demographic information such as gender, date of birth, Social Security number, medical record number, address, race and ethnicity, admission and discharge dates, encounter types, and disposition (i.e., intended care setting following discharge). Optional additional elements might be emergency contacts, allergies, and problem lists. This file lists a unique identification number for each patient and is a cross-reference used to obtain a patient’s health record. Also referred to as member index .

Master plan

Employee-benefit retirement plan created by a financial institution or insurer that can be adopted only by plan sponsors who use the financial institution to fund the plan.

Material Safety Data Sheet (MSDS)

Document that informs industrial purchasers and users of hazardous chemicals of the reasonably foreseeable physical and chemical hazards that may arise from the use of those chemicals. Most materials packaged for consumer use are exempt from the requirements of the Hazard Communication Standard (HCS). The MSDS should include precautions for normal use, handling, storage, disposal, and spill cleanup. The HCS requires that accurate information be provided on the MSDSs. This applies as much to “overwarning” on the MSDS and label, as well as the absence of information (“underwarning”).
