Using the coding techniques described in this chapter, carefully read through the case study and determine the most accurate CPT code(s) and HCPCS code(s) and modifier(s), if appropriate. Harrison Parker, a 69-year-old right-handed male, was referred to me for a neurologic evaluation by his internist, Dr. Brady, for a tremor that has been present for approximately 20 years. Patient states that the tremor began insidiously and has progressed gradually. It now involves both hands and affects his handwriting, drinking coffee and other liquids with a cup, and general work that requires manual dexterity. Other people occasionally notice a tremor in his head. He is otherwise healthy, although he feels his balance is not quite as good as it used to be. A glass of beer or wine markedly decreases the tremor severity. His mother and daughter also have tremor. Patient denies smoking. On examination, he has a rather regular tremor of approximately 8 cycles per second (Hz) with his hands extended…
Activities 1. Diseases Affecting Myelination Myelin sheaths, produced by oligodendrocytes and Schwann cells in the nervous system, serve to protect and insulate the axons of neurons with a fatty tissue. This allows electrical signals to propagate very quickly along the axon. In multiple sclerosis (MS), this myelination is disrupted in the CNS causing inflammation and damage to those axons, leaving scars (plaques) and interrupting the transmission of impulses (Figure 10.9). MYELIN SHEATH DESTRUCTION Figure 10.9. Nerve affected by multiple sclerosis. Question 1 Guillain-Barre Syndrome is another type of demyelination disease. Research this disease and provide one similarity and one difference between it and MS. Question 2 2. What type of neuroglial cell would you expect to find increased after brain injury and why?

Outline the neurochemical transmission and inhibition of pain. Then using the gate-control theory, devise a plan to minimize pain during your next visit to the dentist.
View an electron micrograph of a cross-section of a myelinated nerve fiber image below. The axon contains microtubules and neurofilaments, bounded by a plasma membrane known as the axolemma. Outside the plasma membrane of the axon is the myelin sheath, which is composed of the tightly wrapped plasma membrane of a Schwann cell. What aspects of the cells in this image react with the stain that makes them the deep, dark, black color, such as the multiple layers that are the myelin sheath?
