A 28-year-old male with a history of IV heroin dependence is admitted for pneumonia. A pulmonologist is consulted to assist with the patient’s treatment and an antibiotic for Pneumocystis carinii pneumonia is administered. Low potassium is treated as well. The final diagnoses were coded as: B20, B59, E87.6, and F11.21. What is the discrepancy noted between the coding and the documentation? Question 22 options: The “history of” code reflects abuse rather than dependence The correct code for the pneumonia should be J18.9 The assignment of B20 has no supportive documentation The hypokalemia should not be coded as that is integral to the pneumonia
