• Resource: pp. 130–135 of Medical Insurance
• Write a response in which you determine a diagnosis code category for the following case studies, and explain the rationale for your selections:
o A 68-year-old male presents to the office complaining of pronounced weakness on the right side of his body and slurred speech for the past 24 hours. Based on the examination, the physician orders an MRI to investigate a possible transient ischemic attack.
This would be under the Diseases of the Circulatory System – Codes 390 -459. Ischemic heart disease conditions- those caused by reduced blood flow to the heart- are coded under categories 410-414.
o A 44-year-old male presents to the office complaining of intermittent chest pain. The physician orders an EKG to rule out a possible cardiac event.
This would be under the Symptoms, Signs, and Ill-Defined Conditions – Codes 780-799 Codes in this chapter classify patient’s signs, symptoms, and ill-defined conditions for which a definitive diagnosis cannot be made. In physician practice coding, these codes are always used instead of coding rule-out, probable, or suspected condition.
o A 72-year-old diabetic female exhibits a nonhealing wound on her left foot.
This would be under Endocrine, Nutritional, and Metabolic Diseases, and immunity Disorders – Codes 240-279, these codes classify a variety of conditions. The most common disease here is diabetes mellitus, which is a progressive disease of either type 1 or type 11. The nonhealing would on her left foot, cause be because she is a diabetic.
