What chapter of ICD-10-CM contains codes for diseases of the respiratory system?

The correct answer is Chapter 10 of the ICD-10-CM, which specifically encompasses codes for diseases of the respiratory system. This chapter includes a comprehensive range of conditions affecting the respiratory tract, such as asthma, pneumonia, chronic obstructive pulmonary disease, and lung infections, among others.

Understanding the organization of the ICD-10-CM is crucial for accurate coding and billing in healthcare settings. Each chapter groups diseases and conditions by body systems or certain characteristics, allowing for streamlined coding procedures. Chapter 10's focus on the respiratory system means that it is the designated section for healthcare practitioners to reference when coding respiratory disorders, aiding in the efficient management of patient care and documentation.

In contrast, other chapters, such as those related to diseases of the circulatory system, digestive system, or musculoskeletal system, do not cover respiratory conditions, which reinforces the importance of being familiar with the structure and contents of the ICD-10-CM coding manual.
