Title: Module 3 Coding Diseases
Course: Introduction to Coding and Classification Systems > Section: Module 3: Coding Diseases of the Blood and Nervous Systems

Introduction

Great Job! You are now on your way. Your next stop on your journey, in Module 3, will take you into coding diseases of the blood and blood forming organs and diseases of the nervous system and sense organs. There are only two chapters (13 and 14) so this is a little reprieve before going on to Module 4.

You will learn to code conditions such as anemias, coagulation defects, diseases of the white blood cells, epilepsy, hemiplegia, dysreflexia, disorders of the peripheral nervous system and numerous disorders of the sense organs.

In this module special attention should be given to how to code patients who are treated with anticoagulants and results in thrombocytopenia. Heparin induced thrombocytopenia is a common severe side effect of treatment with anticoagulants. An E-Code should be coded additionally, so going back to your E-Codes Chapter 8 is a good idea to refresh on coding E-Codes. Never assign an E-Code as a principal diagnosis!

Course Outcomes

- Recognizes the basic coding steps for coding medical diagnosis in both ICD-9-CM and ICD-10-CM. (1)
- Comprehends the basic coding guidelines established by the American Hospital Association for both ICD-9-CM and ICD-10CM. (2)
- Converts medical documentation into both ICD-9-CM and ICD-10-CM codes. (3)
