Source-derived summary

The Mortality Medical Data System (MMDS) is used to automate the entry, classification, and retrieval of cause-of-death information reported on death certificates throughout the United States and in many other countries. The National Center for Health Statistics (NCHS) began the system's development in 1967.

The system has facilitated the standardization of mortality information within the United States, and ACME has become the de facto international standard for the automated selection of the underlying cause of death from multiple conditions listed on a death certificate.

System components

The MMDS system consists of the following components, and is itself part of the National Vital Statistics System.

MICAR

There are two Mortality Medical Indexing, Classification, and Retrieval components.

SuperMICAR automates the MICAR data entry process. This program is designed as an enhancement of the earlier PC-MICAR Data Entry program. Super-MICAR is designed to automatically encode cause-of-death data into numeric entity reference numbers.

MICAR200 automates the multiple cause coding rules and assigns International Statistical Classification of Diseases and Related Health Problems (ICD) codes to each numeric entity reference number.

ACME

The Automated Classification of Medical Entities program automates the underlying cause-of-death coding rules.

Editorial summary

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1967—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Mortality, Medical and Data.
Editorial analysis

Why this record matters

“Mortality Medical Data System” is worth following because a concise public description often conceals a longer documentary argument. Here, Mortality, Medical and Data provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 12, 2026. The linked authority identifier is Q6914397. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1967.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
