Replacement slots serve as a placeholder for a value that is not known at the time of authoring, but which can be completed at a subsequent time using data recorded elsewhere (such as in an information model or entered into a data entry form). A slot indicates that it may be replaced by a value by including a plus sign (

Concept
ShowPartsterm
t+
) as the first symbol within the slot. Replacement slots may be used in an expression template wherever a concept, expression or symbol may appear within an expression. 

...

A replacement slot may be used to delay the selection of a focus concept in an expression. For example, the expression template below uses a slot to indicate that the focus concept in the expression can be replaced with any appropriate SNOMED CT expression. This expression template represents any expression with a single refinement in which the

Concept
ShowPartsterm
t272741003|Laterality|
equals
Concept
ShowPartsterm
t24028007|Right|
.

Scg expression
Borderridge
ShowFormatblock
   	[[+]]:  272741003 |Laterality|  =  24028007 |Right|

If the following values are provided to complete the slot:

Scg expression
Borderridge
   	182245002 |Entire upper limb|
   	182281004 |Entire lower limb|
   	244486005 |Entire eye|
   	1910005 |Entire ear|

then the expressions that result from processing the template would be:

Scg expression
Borderridge
   	182245002 |Entire upper limb|:  272741003 |Laterality|  =  24028007 |Right|
   	182281004 |Entire lower limb|:  272741003 |Laterality|  =  24028007 |Right|
   	244486005 |Entire eye|:  272741003 |Laterality|  =  24028007 |Right|
     	1910005 |Entire ear|:  272741003 |Laterality|  =  24028007 |Right|

Attribute Value

A replacement slot may also be used to replace an attribute value in an expression. For example, the expression template below represents any expression with a focus concept of 

Concept
ShowPartsterm
t404684003 |Clinical finding|
 and a refinement which uses the attribute
Concept
ShowPartsterm
t363698007 |Finding site|.
ShowFormatinline
The value of the
Concept
ShowPartsterm
t363698007 |Finding site|
 attribute may be replaced by any valid value at a future time.

Scg expression
Borderridge
ShowFormatblock
   	404684003 |Clinical finding|: 363698007 |Finding site| = [[+]]

...

Scg expression
Borderridge
ShowFormatblock
	   53120007 |Upper limb structure|

...

Scg expression
Borderridge
ShowFormatblock
   	404684003 |Clinical finding|: 363698007 |Finding site| = 53120007 |Upper limb structure|

...

Scg expression
Borderridge
ShowFormatblock
   	53120007 |Upper limb structure|: 272741003|Laterality| = 7771000 |Left|

...

Scg expression
Borderridge
ShowFormatblock
   	404684003 |Clinical finding|: 363698007 |Finding site| = (53120007 |Upper limb structure|: 272741003|Laterality| = 7771000 |Left|)

...

A replacement slot may also be used to replace an attribute name in an expression. For example, the expression template below represents any expression with a focus concept of 

Concept
ShowPartsterm
t404684003 |Clinical finding|
 and a refinement whose value equals
Concept
ShowPartsterm
t58718002 |Rheumatic fever|
ShowFormatinline
The attribute name in the expression may be replaced by any valid attribute concept at a future time.

Scg expression
Borderridge
ShowFormatblock
   	404684003 |Clinical finding|: [[+]] = 80166006 |Streptococcus pyogenes|

...

Scg expression
Borderridge
ShowFormatblock
	   42752001 |Due to|
   	255234002 |After|

then the expressions that result from processing the template would be:

Scg expression
Borderridge
ShowFormatblock
   	404684003 |Clinical finding|: 42752001 |Due to| = 80166006 |Streptococcus pyogenes|
   	404684003 |Clinical finding|: 255234002 |After| = 80166006 |Streptococcus pyogenes|
