MAC   -   [1] Media Access Control, a unique address identifier assigned to network devices. [2] Medicare Administrative Contractor.

Malware   -   Short for "Malicious Software." Malware is a general term for a wide range of intrusive or hostile computer software. Malware includes computer viruses, worms, trojan horses, spyware, adware, most rootkits, and other malicious programs. Malware is used to disrupt computer operation, gather sensitive information, or gain access to private computer systems.   See Adware, Computer Virus, Countermeasure, Flame, Keylogging, Rootkit, Spyware, Trojan Horse, Worm, Zero Day Attack

Mark   -   See Symbol

Master Person Index   -   See MPI

May   -   An imperative defined by RFC 2119.   See Imperative, RFC, Should

MDDS   -   Medical Device Data System.

MDM   -   Medical Document Management segment of an HL7 message.   See HL7

Medical Records Institute   -   The Medical Records Institute sponsored the annual TEPR (Towards Electronic Patient Records) conferences for 25 years. The final conference was held in Palm Springs in February 2009. Later that month the leadership of the MRI launched the mHealth Initiative, focused on the emergence of mobile healthcare devices.

Medi-Cal   -   The local California name for the Medicaid Program.   See DHCS

MedInfo   -   World Congress on medical informatics held every two years: MedInfo 2013 was held in Copenhagen, Denmark; MedInfo 2015 will be in Sao Paulo, Brasil; and MedInfo 2017 will be in Beijing, China.   See AMIA, IMIA, Informatics

Megabyte   -   A semi-ambiguous multiple of the unit byte. Depending upon the context, a megabyte is 1,000 kilobytes (IEEE and ISO digital standards) or 1,024 kilobytes (memory circuits with a binary architecture). As the variance is small, and as the international electronic standards community has shown no discipline for sorting out the terms, they are ambiguously interchanged.   See Byte, Gigbyte, Kilobyte

Mendocino HRE   -   Mendocino Health Records Exchange was the transitional name of two demonstration projects on electronic health data interoperability in Mendocino County, California: [1] the Connecting for Health Record Locator Service project was active from June 2005 to April 2006; and [2] the Connecting for Health NHIN Architecture Prototype project was active from November 2005 to January 2007. In both projects health data interoperability solutions developed by the Mendocino SHARE project were featured in nationwide demonstrations. As a subcontractor on the federal contract "Mendocino HRE" was a DBA of Redwood MedNet. The business name "Mendocino HRE" was retired by Redwood MedNet after the completion of the Prototype Architecture project. The community successor to the interoperability services investigated by the Mendocino HRE effort is Redwood MedNet.   See Connecting for Health, DBA, Mendocino SHARE, NHIN, Prototype Architecture, RHIC, Redwood MedNet

Mendocino SHARE   -   The Mendocino SHARE Project was active during 2003 - 2006 in Mendocino County, California. Mendocino SHARE was initially conceived in 2003 as a community wide health data exchange service modeled on the Santa Barbara County Care Data Exchange (SBCCDE). Mendocino SHARE was funded by HRSA to develop a community technology infrastructure. In 2005, after two years of software development to create a community-based interoperability service, the Mendocino SHARE partnership repurposed the remaining federal grant funds for twelve community partners to purchase software for site level use at six of the community partner sites. After the third year of HRSA funds were disbursed, the Mendocino SHARE project was closed.   See HRSA, Mendocino HRE, RHIC, Redwood MedNet, SBCCDE

Message   -   See Instructions.

Metadata   -   Literally, "data about data." Ambiguously used in one of two distinct meanings: [1] data about the container that carries or stores data; or [2] data about the content, i.e., data about the data. See OWL, RDF, Semantic Web.

MFL   -   Master Facility List.   See Facility Registry

MFN   -   Master File Notification segment of an HL7 message.   See HL7

MHS   -   Military Health System.   See CHCS.

MIME   -   Multipurpose Internet Mail Extensions, defined by RFC 2045 and RFC 2046.   See RFC

MITA   -   Medicaid Information Technology Architecture.

MLLP   -   Minimal Lower Layer Protocol, defined in 1981 by the Transmission Control Protocol (TCP).   See LLP, TCP

MMA   -   Medicare Prescription Drug Improvement and Modernization Act of 2003.

MMIS   -   Medicaid Management Information System.

MMPA   -   Modular Model Participation Agreement.   See Data Use Agreement

Modem   -   Short for "Modulator-Demodulator", a device for converting digital signals into analog tones for transmission over analog phone lines.   See POTS

Model   -   A model is anything used in any way to represent anything else. Some models are physical objects, such as a model of a new building to be built. A conceptual model may be drawn on paper, described in words or symbols, or imagined in the mind.   See Algorithm, Concept, Schema, Symbol

ModSpec   -   Slang for "modular specification" which is a best practice in software engineering. ONC operates a ModSpec team that reviews and optimizes software code as part of the Standards and Interoperability Framework process.   See Direct Project, HPD, ONC, S&I Framework

MongoDB   -   The Mongo Database (from "humongous") is a scalable, high-performance, open source, document-oriented NoSQL database written in C++.   See DBMS, NoSQL

MOU   -   Memorandum of Understanding

Mouse   -   In computing, a mouse is a pointing device that translates two-dimensional motion into computer instructions. Plural of "mouse" is "mouse devices".   See GUI, PARC

MPFS   -   Medicare Physician Fee Schedule.   See CMS, RVU

MPI   -   A Master Person Index is a longitudinal index linking individual indentities across multiple separate sites, such as linking health care data for the same patient at separate health care facilities, or linking data for the same patient across different software applications at the same health care facility.   See Disambiguate, EIS, EMPI, OpenEMPI, PIX, RLS, SBCCDE

MRP   -   Material Requirements Planning (MRP) is a production planning and inventory control system used to manage manufacturing processes. MRP arose in the 1960s out of the Toyota Manufacturing Program. In the 1980s this evolved into MRP-II with the addition of master schedule and capacity planning components. In the 1990s MRP-II evolved further into ERP.   See CRM, EDI, ERP, MRP-II, Supply Chain

MRP-II   -   Manufacturing Resource Planning (MRP-II) is a second generation production planning and inventory control system that arose from limitations in MRP. While MRP was primarily concerned with materials, MRP-II was concerned with the integration of all aspects of the manufacturing process, including more agile and adaptive master scheduling of materials plus finance and capacity planning. In the 1990s MRP-II evolved further into ERP.   See CRM, ERP, MRP, Supply Chain

MSH   -   The Message Header segment of an HL7 message   See HL7

MU   -   Meaningful Use (MU) is a term introduced by the 2009 HITECH legislation, which appropriated incentive funds for CMS to distribute for the "adoption and meaningful use of certified EHR technology" (CEHRT). In response, CMS issued guidance "for the definition of meaningful use to be consistent with applicable provisions of Medicare and Medicaid law while continually advancing the contributions certified EHR technology can make to improving health care quality, efficiency, and patient safety."   See ARRA, CEHRT, CMS, EH, EHR, EP, HITECH, PHR, P4P, VDT

MUA   -   ("MOO-uh")   A Medically Underserved Area is a designation created and maintained by the Health Resources and Services Administration (HRSA).   See HHS, HPSA, HRSA

MUP   -   Medically underserved population.   See MUA

Must   -   An imperative defined in RFC 2119.   See Imperative, RFC, Shall

MVX   -   External HL7 Table 0227 is maintained by the CDC. The table uses two or three letter abbreviations to designate manufacturers of vaccine products.   See CDC, CVX, HL7, QBP, VXU
