ICD-10 Coding/Diseases of the Nervous System

This lesson introduces ICD-10-CM Diseases of the Nervous System.

Objectives and Skills
Objectives and skills for this lesson include:


 * 1) Apply ICD-10-CM coding guidelines for accurate selection and sequencing of diagnosis codes commonly used to describe diseases of the nervous system.
 * 2) Apply ICD-10-PCS coding guidelines for accurate selection of procedure codes commonly used to diagnose and treat diseases of the nervous system.
 * 3) Explain the difference between the central and peripheral nervous system.
 * 4) Identify the symptoms associated with Parkinson's disease and medications used to treat the condition.
 * 5) Recognize that dementia is an inherent part of Alzheimer's disease and know how to code behavioral disturbances including wandering.
 * 6) Distinguish between seizure and epilepsy.
 * 7) List terms, that when documented by the physician in describing epilepsy, equate to "intractable" for the 4th character of codes in category G40- of ICD-10-CM.
