SECTION I – INSTRUCTIONS FOR CLASSIFYING THE UNDERLYING CAUSE OF DEATH, 2020

INTRODUCTION

This manual provides instructions to mortality medical coders and nosologists for coding the underlying cause of death from death certificates filed in the states. These mortality coding instructions are used by both the State vital statistics programs and the National Center for Health Statistics (NCHS), which is the Federal agency responsible for the compilation of U.S. statistics on causes of death. NCHS is part of the Centers for Disease Control and Prevention.

In coding causes of death, NCHS adheres to the World Health Organization Nomenclature Regulations specified in the most recent revision of the International Statistical Classification of Diseases and Related Health Problems (ICD). NCHS also uses the ICD international rules for selecting the underlying cause of death for primary mortality tabulation in accordance with the international rules.

Beginning with deaths occurring in 1999, the Tenth Revision of the ICD (ICD-10) is being used for coding and classifying causes of death. This revision of the Classification is published by the World Health Organization (WHO) and consists of three volumes. Volume 1 contains a list of three-character categories, the tabular list of inclusions and the four-character subcategories. The supplementary Z code appears in Volume 1 but is not used for classifying mortality data. Optional fifth characters are provided for certain categories and an optional independent four-character coding system is provided to classify histological varieties of neoplasms, prefixed by the letter M (for morphology) and followed by a fifth character indicating behavior. These optional codes are not used in NCHS. Volume 2 includes the international rules and notes for use in classifying and tabulating underlying cause-of-death data. Volume 3 is an alphabetical index containing a comprehensive list of terms for use in coding. Copies of these volumes may be purchased in hardcopy or on diskettes from the following address:

NCHS has prepared an updated version of Volume 1 and Volume 3 to be used for both underlying and multiple cause-of-death coding. The major purpose of the updated version is to provide a single published source of code assignments including terms not indexed in Volume 3 of ICD-10. NCHS has included all non-indexed terms encountered in the coding of deaths during 1979-1994, under the Ninth Revision of the International Classification of Diseases (ICD-9). Due to copyright considerations, the updated Volumes 1 and 3 may not be reproduced for distribution outside of NCHS and State vital statistics agencies. With the availability of the updated Volumes 1 and 3, NCHS will discontinue publishing the Part 2e manual, Non-indexed Terms, Standard Abbreviations, and State Geographic Codes as Used in Mortality Data Classification that was first published in 1983. The list of geographic codes (Appendix C), the list of abbreviations used in medical terminology (Appendix D), and the synonymous sites list (Appendix E) are included in this publication.

ICD-10 provides for the classification of certain diagnostic statements according to two different axes – etiology or underlying disease process and manifestation or complication. Thus, there are two codes for those diagnostic statements subject to dual classification. The etiology or underlying disease process codes are marked with a dagger (†), and the manifestation or complication codes are marked with an asterisk (*) following the codes in ICD-10. NCHS does not use the asterisk codes in mortality coding. For example, cytomegaloviral pneumonia has a code marked with a dagger (B25.0†) and a different code, marked with an asterisk (J17.1*). In this example, only the dagger code (B25.0) would be used.

Major Revisions from Previous Manuals

Corrections have been made to clarify instructions, spelling and format throughout the manual. These changes are not specifically noted.
Section III, Part B, 1, a, added ‘necrotizing’ to the list of modifiers considered a one-term entity.
Section III, Part H, Non-Traumatic Conditions, deleted instruction and moved example to Section III, Part J, 1, Coding Conditions Classified to Injuries as Disease Conditions.
Section III, Part I, #1 added info and example to show that the injuries due to disease instruction does not apply when condition is qualified as traumatic.
Section IV, Part B, O00-O99, changed age to 44.
Section IV, Part B, O00-O99, added list of maternal checkbox options and a new maternal instruction for checkbox only records.
Section IV, Part B, X40-X49, 1, b, expanded instruction to show intentional reported with drug poisoning is suicide.
Appendix D, added interstitial lung disease to abbreviation ILD.

MEDICAL CERTIFICATION

The U. S. Standard Certificate of Death provides spaces for the certifying physician, coroner, or medical examiner to record pertinent information concerning the diseases, morbid conditions, and injuries which either resulted in or contributed to death as well as the circumstances of the accident or violence which produced any such injuries. The medical certification portion of the death certificate is designed to obtain the opinion of the certifier as to the relationship and relative significance of the causes which he reports.

A cause of death is the morbid condition or disease process, abnormality, injury, or poisoning leading directly or indirectly to death. The underlying cause of death is the disease or injury which initiated the train of morbid events leading directly or indirectly to death or the circumstances of the accident or violence which produced the fatal injury. A death often results from the combined effect of two or more conditions. These conditions may be completely unrelated, arising independently of each other or they may be causally related to each other, that is, one cause may lead to another which in turn leads to a third cause, etc.

The order in which the certifier is requested to arrange the causes of death upon the certification form facilitates the selection of the underlying cause when two or more causes are reported. He is requested to report in Part I on line (a) the immediate cause of death and the antecedent conditions on lines (b), (c) and (d) which gave rise to the cause reported on line (a), the underlying cause being stated lowest in the sequence of events. However, no entry is necessary on I(b), I(c) or I(d) if the immediate cause of death stated on I(a) describes completely the sequence of events.

Any other significant condition which unfavorably influenced the course of the morbid process and thus contributed to the fatal outcome but was not related to the immediate cause of death is entered in Part II.

DEFINITIONS

The terms defined in this section are used throughout the manual.

A reported sequence two or more conditions on successive lines in Part I, each condition being an acceptable cause of the one on the line immediately above it.

Accident in medical care a misadventure or poisoning occurring during surgery or other medical care.

Causation table (Table D) contains address codes and subaddress codes that indicate an acceptable causal relationship (reported sequence). Table D is in Part 2c Instruction Manual.

Combination code a third code which is the result of the merging of two or more codes.

Conflict in linkage when the selected underlying cause links con-currently “with” or in “due to” position with two or more conditions.

Contributory cause any cause of death that is neither the direct, intervening, originating antecedent nor underlying is a contributory cause of death.

Direct cause of death also known as terminal cause of death, is the condition entered on line I(a) in Part I. If the certifier has entered more than one condition on line I(a), these terms apply to the first one. In the selection rules themselves, the direct cause is often referred to as the condition first entered on the certificate.

Direct sequel a condition which is documented as one of the most frequent manifestations, consequences, or complications of another condition.

“Due to” position when there are entries on more than one line in Part I with only one entity on the lowest used line in Part I, the single entity on the lowest used line is considered to be in a “due to” position of all entries entered above it. When there are entries on more than one line in Part I, each entity on the lower of two lines is considered to be in a “due to” position of each entity on the next higher line.

Entity a diagnostic term or condition entered on the certificate of death that constitutes a codable entry.

Error in medical care a misadventure or poisoning occurring during surgery or other medical care.

Further linkage another step in the linkage process which must be made to conform with the Classification after one or more linkages have been made.

Intervening cause any causes between the originating antecedent cause and the direct cause of death are called intervening causes.

Late maternal death the death of a woman from direct or indirect obstetric causes more than 42 days but less than one year after termination of pregnancy.

Maternal death the death of any woman while pregnant or within 42 days (less than 43 days) of termination of pregnancy, irrespective of the duration and the site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incidental causes.

Modification table (Table E) contains address codes and subaddress codes that are used with Selection Rule 3 and Modification Rules A, C, and D. Table E is in Part 2c Instruction Manual.

Multiple one-term entity a diagnostic entity consisting of two or more words together on a line for which the Classification does not provide a single code for the entire entity but does provide a single code for each of the components of the diagnostic entity.

One-term entity a diagnostic entity that is classifiable to a single ICD-10 code. It can be one word or more than one word.

Originating antecedent cause this term designates the condition entered on the lowest used line in Part I, or, if the certificate has not been filled out correctly, the condition that the certifier should have reported there. The originating antecedent cause is, from a medical point of view, the starting point of the train of events that eventually caused the death.

Preference code a code which has priority over other code(s) which may also qualify as a combination code.

Perinatal period the period which commences at 22 completed weeks (154 days) of gestation (the time when birth weight is normally 500 g), and ends seven (7) completed days after birth.

Properly positioned condition(s) placed in an appropriate order to form a sequence of events.

Selected underlying cause of death a condition which is chosen either temporarily or finally by the application of an international selection rule.

Sequence two or more conditions entered on successive lines of Part I, each condition being an acceptable cause of the one entered on the line above it.

Trivial condition a condition which will not of itself cause death. The trivial conditions are listed in Part 2c Instruction Manual in Table H.

TUC NCHS abbreviation for tentative underlying cause. This is the same as the originating antecedent cause.

Underlying cause of death the disease or injury which initiated the train of morbid events leading directly to death or the circumstances of the accident or violence which produced the fatal injury.

CREATED CODES

To facilitate automated data processing, the following ICD-10 codes have been amended for use in coding and processing the multiple cause data. Special five-character subcategories are for use in coding and processing the multiple cause data; however, they will not appear in official tabulations.
