**Code****Display****Definition**A intersect Form the intersection with the value. E exclude Form the set-difference with this value, i.e., exclude this element or set from the resulting set. H convex hull Form the convex hull with the value. The convex hull is defined over ordered domains and is the smallest contiguous superset (interval) that of all the operand sets. I include Form the union with this value, i.e., include this element or set in the resulting set. P periodic hull Form the periodic hull with the value. The periodic hull is defined over ordered domains and is the periodic set that contains all contiguous supersets of pairs of intervals generated by the operand periodic intervals.

This value set contains 5 concepts

Code | System | Display | Definition |

A | http://terminology.hl7.org/CodeSystem/v3-SetOperator | intersect | Form the intersection with the value. |

E | http://terminology.hl7.org/CodeSystem/v3-SetOperator | exclude | Form the set-difference with this value, i.e., exclude this element or set from the resulting set. |

H | http://terminology.hl7.org/CodeSystem/v3-SetOperator | convex hull | Form the convex hull with the value. The convex hull is defined over ordered domains and is the smallest contiguous superset (interval) that of all the operand sets. |

I | http://terminology.hl7.org/CodeSystem/v3-SetOperator | include | Form the union with this value, i.e., include this element or set in the resulting set. |

P | http://terminology.hl7.org/CodeSystem/v3-SetOperator | periodic hull | Form the periodic hull with the value. The periodic hull is defined over ordered domains and is the periodic set that contains all contiguous supersets of pairs of intervals generated by the operand periodic intervals. |

Explanation of the columns that may appear on this page:

Level | A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies |

System | The source of the definition of the code (when the value set draws in codes defined elsewhere) |

Code | The code (used as the code in the resource instance) |

Display | The 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 |

Definition | An explanation of the meaning of the concept |

Comments | Additional notes about how to use the code |
