Abstract: Upon request, a computer can provide a useful collection of medical coding data to another computer on a network. The collection can be tailored to a particular medical specialty. The collection can be provided in a printable form that relates the various code relationships which may be needed for accurate use of the codes. Various embodiments may provide a book with a separate page for each code that includes the fee for the code, codes that are mutually exclusive with the code, and codes that may be needed in addition to the code. Other useful information can also be associated with the codes provided in the collection. Appropriate fees for codes in the collection can be provided, which may need to be calculated for each medical services provider depending on variables such as a geographic location of the medical service provider.
