A data.frame containing the following variables:

year

Year of validity (from 2004)

level

Level of the hierarchy (3, 4 or 5 digits)

terminal

Whether the code is a terminal code (i.e. with no further subcodes) (T: yes; N: no)

subcode_type

Whether the subcode is pre- or postcombinated (X: precombinated; S: postcombinated). Precombinated codes are listed directly under the three-digit ICD code, whereas postcombinated codes are lists of possible values for the fourth and fifth digits that are not specific to the particular code (e.g. the group E10-E14 shares a common list of postcombinated fourth and fifth digits)

chapter_nr

Chapter number (arabic digits 1-22)

icd_block_first

First code in the respective ICD block, can be used to join with the table ICD10gm::icd_meta_blocks

icd_code

Full icd code (up to 7 characters) with all symbols except the "dagger" (for aetiological codes that can be combined with an "asterisk" code to denote the manifestation)

icd_normcode

The ICD "normcode", consisting of up to 6 characters and without all symbols except the period (e.g. E11.30)

icd_sub

The ICD "normcode", consisting of up to 5 characters and without any symbols (e.g. E1130)

label

ICD label for the complete code.

label_icd3

ICD label for the three-digit ICD code.

label_icd4

ICD label for fourth digit of the ICD code.

label_icd5

ICD label for the fifth digit of the ICD code.

usage_295

Usage of the code in the ambulatory sector (Paragraph 295 SGB V) (P: primary code; O: only as a "star" code in conjunction with a "dagger" code for aetiology; Z: only an optional "!" code in conjunction with a primary code; V: not to be used for coding)

usage_301

Usage of the code in the stationary (hospital) sector (Paragraph 301 SGB V) (P: primary code; O: only as a "star" code in conjunction with a "dagger" code for aetiology; Z: only an optional "!" code in conjunction with a primary code; V: not to be used for coding)

mort_list1

Key to join with the WHO mortality list 1

mort_list2

Key to join with the WHO mortality list 2

mort_list3

Key to join with the WHO mortality list 3

mort_list4

Key to join with the WHO mortality list 4

morb_list

Key to join with the WHO morbidity list

gender_specific

Whether the diagnosis is gender specific (M: male; W: female; 9: Not gender specific)

gender_error_type

Type of error implied by the field gender_specific (9: irrelevant; K: possible error)

age_min

Minimum age for which the diagnosis is plausible (T001: from one day; Y005: from five years)

age_max

Maximum age for which the diagnosis is plausible (T010: up to 10 days; Y005: up to five years)

age_error_type

Type of error resulting from implausible age (9: irrelevant; M: always an error ("Muss-Fehler"); K: possible error ("Kann-Fehler"))

rare_in_central_europe

Indicates whether the diagnosis is rare in Central Europe (J: yes; N: no)

code_with_content

Indicates whether the code has content associated with it (J: yes; N: no, leads to an error)

notifiable

Indicates whether the diagnosis is notifiable in Germany (J: yes; N: no)

notifiable_lab

Indicates whether the diagnosis is notifiable for laboratories in Germany (J: yes; N: no)

Details

This metadata is not suitable for operative coding and does not include all relevant information concerning the codes. For example, the file contains neither the inclusion and exclusion notes nor the detailed definitions (where present, mainly in Chapter V). DIMDI provide additional reference material for operative coding and detailed research.
