1. A method of exchanging medical information with a medical management system, comprising:
receiving, using a processor of a code point resolver, from the medical management system, medical text via a network interface, wherein a code point is a single standardized medical terminology code (SMTC) that corresponds to a medical concept contained within the medical text;
applying rule-based logic to process the medical text to form a localized mapping of a text portion of the medical text to a plurality of candidate SMTCs (CSMTCs) that are related to at least one metathesaurus concept entity (MCE) in a metathesaurus and to determine the code point from the CSMTCs, wherein applying rule-based logic comprises:
determining a fitness score with a fitness scorer of the rule-based logic for each of the CSMTCs using weightings that are based on a medical application intent, a hypernym and hyponym relationship, a source reliability measure, and codes determined by an industry acceptance rating; and
determining the code point by selecting a best-fit SMTC having a highest fitness score of the CSMTCs; and
transmitting, via the network interface, to the medical management system, the code point.
