Title: The Respiratory and Circulatory Systems
Course: Intermediate Coding and Classification Systems > Section: Module 7: The Respiratory and Circulatory Systems

Introduction

Excellent work! Keep it up. Chapters 10 and 11 cover the Respiratory and Circulatory systems, respectively. There are many procedures performed on these two systems. The respiratory system includes the mouth and throat and is common to the digestive system too. Procedures performed specifically on the pleural cavity and not the pleura itself, are classified to the Anatomical Regions body system in Chapter 7. Make sure you read the coding guidelines carefully in these two chapters.

Chapter 11 addresses the circulatory system including the heart, great vessels, arteries, veins and capillaries. Review the anatomy of the heart and its arteries, veins, and chambers. The coronary arteries include the right coronary artery, left main coronary artery, the circumflex artery, and the left anterior descending coronary artery. Table 11.1 designates the Root Operation Values for the Circulatory System.

Take special note on coding of coronary artery bypass grafts. Review the coding guideline in this section of this chapter thoroughly. (CG- B3.6b and CB.6c).

If multiple coronary artery sites are bypassed, a separate procedure is coded foe each coronary artery site that uses a different device or qualifier.

Course Outcomes

- Describes the basic coding steps for coding medical procedures in both ICD-9-CM and ICD-10-PCS. (1)
- Interprets the basic coding guidelines established by the American Hospital Association for both ICD-9-CM and ICD-10-PCS. (2)
- Converts medical documentation into both ICD-9-CM and ICD-10-PCS codes. (3)
- Applies the official coding guidelines to the coding of medical procedures for all body systems (circulatory, respiratory, musculoskeletal, urinary, blood organs, reproductive, gastrointestinal, etc.) (4)
- Compares and contrasts the differences between the ICD-9-CM and ICD-10-PCS classification systems. (8)
