Possibly equivalent to 

• The inactivated concept is inherently ambiguous.
• Every effort should be made to identify all of the clinically useful "POSSIBLY_EQUIVALENT_TO" target concepts, which should be semantically as close as possible to the meaning of the inactivated concept. Where appropriate, new concepts should be created if they are clinically valid. 
• POSSIBLY_EQUIVALENT_TO target may be singular where the second target is a concept that is of little or no clinical usefulness.  It is not necessary to represent all of the semantic meaning of the inactivated concept if the concepts needed should not exist in SNOMED CT.
• If the FSN is vague, not ambiguous, consider using Meaning of component unknown.

• Applies to concepts with classification type descriptions - do not have to appear in a classification.
• Use with "not otherwise specified", "NOS", "not elsewhere classified", "NEC", "unspecified", "other".

• Use Partially equivalent to : use where there is a conjunction, (where the intended meaning is disjunction for classification purposes, regardless of whether the terms are explicitly written as "with", "and", "and/or") and replacement .  The replacements must include all of the clinically valid elements of the conjunctiondisjunction, e.g. has , two or more concepts as concept target values. 
• Every effort should be made to identify all of the clinically valid PARTIALLY_EQUIVALENT_TO valid Partially equivalent to target concepts , which should be semantically as close as possible to the meaning of the inactivated concept.  Where applicable and appropriate, new concepts should be created if they are clinically validto describe the clinically relevant aspects of the inactivated concept.

• The concept has been made inactive because it has the same meaning as another concept.

Replaced by 

• Applies to FSNs which contain an error, that when corrected, potentially changes the semantic meaning of the concept.
• Where the error is grammatical or a spelling mistake, which when corrected does not change the meaning, the description rather than the concept should be inactivated.

• Meaning of the concept cannot be determined.
• The FSN is vague, not ambiguous.

No suitable replacement identified

0..0

• A suitable replacement cannot be identified or concept is no longer in scope, e.g. administrative, occupation or country concepts are under discussion. 
• When jurisdictional control of a concept passes between extensions, eg. international core and the veterinary extension, or relates to specific forms, legal entities, etc.; no replacement is required.
• Applies to a concept which does not adhere to editorial guidelines eg. grouper that cannot be defined. 
• Applies to concept that does not adhere to Precoordination Naming Patterns
• Replaced by: Where conformance to editorial policy potentially changes the meaning of a concept and it is possible to replace this with a concept that is semantically very close to the inactivated concept.
• Alternative: Editorial policy results in a change in scope e.g. branded products were considered out of scope for SNOMED CT, an Alternative would be the generic product.

No suitable replacement identified

0..0

• The inactivated concept is an outdated concept that is no longer considered to be clinically acceptable or semantically interoperable internationally.
• In some circumstances, an outdated concept simply falls into disuse without any appropriate replacement.
• Possibly replaced by is used when two or more potential replacements exist; two or more concepts as targets can be selected. 
• Replaced by is used when a concept exists that is semantically similar to, or more general than, the inactivated concept for the purposes of reconciling historical data analysis.
