ICD-10 codes consist of a single letter followed by 3 or more digits, with a decimal point between the second and third ( e.g K35.1, "Acute Appendicitis with peritoneal abscess" ). As there are many thousands of variations at the 4 character level - where all three digits are used - it is common practice to summarize at the 3 character level ( e.g. K35, "Acute appendicitis", which includes peritoneal abscess and all other forms of the condition ). The diagnoses are presented in code order ( i.e. rather than by the diagnosis name ). The list of ICD-10 chapters below should help you locate the particular diagnosis you require from these tables:
