The approximate flag is turned on when no one code in the target system or linked combination of codes in the target system expresses the same essential meaning as the code in the source system.
The difference between the two systems is typically in level of details between the codes, and in nearly all cases teh I-10 code is more detailed than the I-9 code.
What does the no map flag mean?
The no map flag distinguishes entries where the source system code has at least one translation from entries where the source system code has no target system translation. Every effort is made to find an acceptable translation in the target system for every code in the source system. The no map flag is used only as a last resort, when there are no acceptable target system translation alternatives for the source system code.
What does 0 in the no map flag field mean?
The no map flag is 0 when there is a translation in the target system for the source system code.
What does 1 in the no map flag field mean?
The no map flag is 1 when there is no acceptable translation in the target system for the source system code.
What does the combination flag mean?
The combination flag distinguishes entries where the source system code has a single (meaning “non-combination”) translation alternative(s) from entries where the source system has a combination alternative(s).
What does 0 in the combination flag field mean?
The combination flag is 0 when the translation alternative in the target system is what is referred to as a single entry rather than a combination entry. A single entry in the context of the GEMs has a specific meaning. It means that the code in the source system linked to one of the translation options in the target system is a considered a complete translation alternative.
What does 1 in the combination flag field mean?
The combination flag is 1 when the translation alternative in the target system is a combination entry. When the combination flag is 1 for a source system code, it means that a cluster of target system codes—consisting of two, three, four, or more codes—taken together provide an adequate translation of the source system code.
What does “scenario” mean?
A source system combination code includes diagnostic conditions or procedures that require more than one separate code in the target system to convey the equivalent amount of information. A combination code may also describe multiple variations of the information in either the code title or the complete meaning of the code. Each of these variations has its own number in the scenario field (the 4th flag). If there is only one scenario in a GEMs combination entry, the scenario number is 1 for all rows in the entry. If there is more than one scenario in a GEMs combination entry, each additional variation of a combination diagnosis or procedure has its own scenario number, beginning with 1, 2, 3, and so on.
What does “choice lists” mean?
Choice lists (the 5th flag) are the method of organization for the translation alternatives in a combination entry. Choice lists organize the distinct components of the target system translation in a combination entry into pick lists. If the source system code requires three distinct target system codes to convey the equivalent amount of information, the target system translation will contain three pick lists. If the target system is more specific along one or more axes of classification, there will be multiple translation alternatives for that axis of classification and the pick list will contain multiple choices. One target system code from each of the choice lists in an entry constitutes a complete translation of the source system combination code. Each instance of a complete translation is called a cluster.
