Module 02 Coding Assignment - Beth Long Directions: The purpose of this assignment is for you to exhibit your critical thinking skills for a medical coding case(s). Your professor will evaluate your answers for coding guideline usage, communication from individual perspective, coding abstraction and sequencing. Please list all answers in the appropriate boxes listed below the questions. 1. What is the principal diagnosis? What pathway did you take in order to code the condition properly? Acute Pyelonephritis N10 2. Given that you’ve provided the correct answer for question #1. Please list the instructional note listed in the tabular list to help support the ICD-10-CM code in question #1? Provide an explanation of why you feel the code listed for the principal diagnosis is appropriate. Acute pyelonephritis is a type of UID where both or one kidney is infected or inflamed. The tubular list helps instruct the coder to use the additional code to identify the infectious agent. The bacteria e. Coli that is documented in the discharge summary and lab reports will be listed s a secondary code and the attending has listed acute pyelonephritis as principal diagnosis as it is listed on the discharge summary. 3. In the History and Physical the patient complains of left upper flank pain should this condition be coded? What coding guideline supports your decision? Explain Guideline B.5, It states that if there is a definitive diagnosis and the conditions are a part of the disease they do not need to be coded separately. With flank pain it is a common symptom. 4. In the family history section of the history and physical the physician documents, “she has a brother with mild epilepsy” should this be coded why or why not? Explain. No it should not be coded. His epilepsy has nothing to do with acute pyelonephritis 5. Given that the principal diagnosis is listed for question #1, please list all secondary diagnoses and the pathways. Please list all appropriate codes and give the proper sequence of the codes listed. E. Coli- B96.20 Dehydration- E86.0

Week 1 Assignment Go to www.sciencedaily.com This site provides a summary of research reports published in many peer-reviewed scientific journals on a weekly basis. The articles are only summaries, and so this is a secondary source of information, rather than the original primary source. However, it is the closest thing to the primary source that most of us will want to get. Choose an article that relates to human biology in some way (it could be an animal study as long as the results can be applied to humans) AND specifically discusses a scientific investigation similar to one described in Chapter 1 of your text. Read and answer the questions below. 1) Provide the direct link to the study here. (Go to the address bar in your browser and copy the whole URL, then paste here). http://www.sciencedaily.com/releases/2014/01/140122091318.htm 2) What is the title of the article? Fever-reducing meds may help spread the flu 3) What was the most likely working hypothesis of the study? That people taking fever reducing medicines such as motrin or Tylenol have a greater risk of spreading the flu virus. 4) What type of study was it (controlled experiment or correlation / epidemiological)? Correlation (a) If a controlled experiment – describe the experimental group and the control group. How many / who were in each group? What was done to the experimental group? What was done to the control group? Does it appear to be a blind or double blind study? (b) If a correlation study – what specific variables did the researchers investigate? What variables did they attempt to control for? Were there any variables that they were not able to control for? Whether or not using medication to control a fever in a person with the flu virus would affect the levels of the virus that person gives off. Whether or not the person was actually infected with the flu virus and the amounts of fever reducing medication they were given. They could not control the range of fevers nor the severity in which they were infected with the flu virus. 5) Summarized the results of the investigation. That the use of fever reducing medications increased the number of annual flu cases by approximately 5% in North America. 6) Discuss 1 question that was raised by this research or that remains unanswered, or what do the researchers plan to do next? Scientists need to research how much fever reducing medication increases the levels of virus a people put off in general. 7) Name the original research journal where this report was published (NOT Science Daily) and the affiliation of the researchers (i.e. what organization did they work for?) If a funding source for the research was listed, please state that. Population-level effects of suppressing fever. Proceedings of the Royal Society B: Biological Sciences, 2014 McMaster University
