 There are also coding systems for symptoms present in the diseases and biological findings.They are normally included in medical dictionaries, also with a codification system.Some of them are MeSH (Medical Subject Headings), COSTART (Coding Symbols for Thesaurus of Adverse Reaction Terms) or MedDRA (Medical Dictionary for Regulatory Activities) Other systems like Current Procedural Terminology do not deal directly with diseases but with the related procedures.
