Expansion based on QuestionnaireItemType v4.6.0 (CodeSystem)

All codes in this table are from the system

0groupGroupAn item with no direct answer but should have at least one child item.
0displayDisplayText for display that will not capture an answer or have child items.
0questionQuestionAn item that defines a specific answer to be captured, and which may have child items. (the answer provided in the QuestionnaireResponse should be of the defined datatype).
1  booleanBooleanQuestion with a yes/no answer (valueBoolean).
1  decimalDecimalQuestion with is a real number answer (valueDecimal).
1  integerIntegerQuestion with an integer answer (valueInteger).
1  dateDateQuestion with a date answer (valueDate).
1  dateTimeDate TimeQuestion with a date and time answer (valueDateTime).
1  timeTimeQuestion with a time (hour:minute:second) answer independent of date. (valueTime).
1  stringStringQuestion with a short (few words to short sentence) free-text entry answer (valueString).
1  textTextQuestion with a long (potentially multi-paragraph) free-text entry answer (valueString).
1  urlUrlQuestion with a URL (website, FTP site, etc.) answer (valueUri).

Explanation of the columns that may appear on this page:

LvlA few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
