ICD 10 Study Guide: Chapter 1 Infectious Parasitic Diseases: Study Guide

ICD-10-CM Chapter 1 covers codes A00 through B99: a wide range of diseases caused by bacteria, viruses, fungi, parasites, and other infectious organisms. This chapter is one of the most guideline-heavy chapters tested on the CPC® exam because of its complex sequencing rules, especially for HIV, sepsis, and drug-resistant organisms.
