Final answer:
In ICD coding, a symbol such as a star (*) next to a code in the tabular list typically indicates that the code is a manifestation only code and should not be used as a principal diagnosis.
Step-by-step explanation:
In medical coding, particularly when dealing with the International Classification of Diseases (ICD), specific symbols next to codes in the tabular list provide guidance on how these codes should be used. When a code is intended to indicate a manifestation of a disease rather than the disease itself, this symbol is integral for coders to know. In the context provided, the symbol that is used to indicate a manifestation only code in the tabular list is not explicitly mentioned. However, in standard ICD coding practices, it is often the case that a star symbol (*) is used to denote a code that represents a manifestation of a condition, and should not be used as a principal diagnosis. It is important to reference the actual coding manual or system used, as different coding systems may use different symbols.
