Title: The Nervous System and Sense Organs
Course: Intermediate Coding and Classification Systems > Section: Module 6: The Nervous System and Sense Organs

Introduction

Great Job! You are now in the know on root operations. It is now necessary to go into each body system and learn specifics on coding procedures and review anatomy. You will find anatomy alerts throughout the next 12 chapters for coding guidance. This week you will cover Chapters 8 the Nervous System and Chapter 9 Sense Organs. You will also look at operative reports to learn to code specific procedures identifying the root operation for each case. Review the material with emphasis on the root operations for the nervous system and sense organs. Remember you must identify all the following seven characters for full code assignment:

- Section
- Body System
- Root Operation
- Body Part
- Approach
- Device
- Qualifier

The first three are obtained from the index and characters 4-7 are determined from the Tables. Always have a medical dictionary and anatomy references available to check your knowledge. You will be provided access to the References within 3M and Quantim which has all of these tools for your use in addition to many more.

Take note of Figure 8.5, Nerves and Plexus of the Peripheral Nervous System separated into the cervical thoracic and lumbar regions. The nervous system consists of two main parts, the central nervous system and the peripheral nervous system. Review the anatomy of both.

ICD-10-PCS classifies all eye muscles to a single body value of extraocular muscles and differentiates between extraocular muscles of the right and left eye. Corneal transplant procedures are coded to the root operation Replacement because the cornea is a body part that is replaced by a biological or synthetic material.

Case Studies are extra work and you should review a few to determine how to code them in the next 12 chapters.

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)

Objectives

Upon completion of this module you should be able to:

- List the basic components and functions of the nervous system, central nervous system and peripheral nervous system.
- Review the anatomy of the central and peripheral nervous systems.
- Discuss the 20 applicable root operations for the central nervous system.
- Discuss the 16 applicable root operations for the peripheral nervous system.
- Identify the use of the body part value “Y” in the peripheral nervous system.
- Review the procedure used to locate values for body parts that do not have their own body part values.
- List the four applicable approaches used in the central and peripheral nervous system.
- Recognize the applicable device values for the central and peripheral nervous system.
- Discuss the use of qualifier values for Bypass and Transfer root operations.
- Identify the meaning of qualifier value B in the central nervous system for cerebral cisterns.
- Describe the function of the eyes, ears, and nose in processing sensory information.
- Review the anatomy of ocular system, ear, nose and sinuses.
- Discuss the common root operations used in coding procedures performed on the sense organs.
- Review the procedure used to locate values for body parts that do not have their own body part values.
- List the applicable approaches used in the eye and ear, nose and sinus and the one approach that is only used in the ear nose and sinus body system.
- Recognize the applicable device values for the sense organs.
- Discuss the use of qualifier values for Bypass procedures in the eye and ear, nose and sinus.
