Course: Introduction to Coding and Classification Systems > Section: Module 2: Supplementary Classifications and Codes

Q: What are the two supplementary classifications provided in ICD-9-CM?
- V codes, M codes
- E codes, M codes
- V codes, E codes
A: V codes, E codes

Q: These codes are used to identify the external causes of injury and poisoning. They are used to indicate the responsible medication for any condition described as an adverse effect of the correct use of a drug or other medicinal or biological substance. They are also used to report the external cause of an injury.
- V Codes
- M codes
- E Codes
A: E Codes

Q: V codes may be used as a first or additional diagnosis.
- True
- False
A: True

Q: E codes should never be used as a principal or first listed diagnosis.
- True
- False
A: True

Q: A patient is seen in the outpatient clinic for colonoscopy due to family history of colon cancer. The patient has no personal history of gastrointestinal disease and is currently without signs and symptoms. Assign the appropriate diagnosis code(s) and sequence according to coding guidelines.

Q: The female patient was admitted with right lower quadrant abdominal pain, diarrhea, fever, chills, and nausea for the past 5 days. Blood and stool cultures were negative.

The patient refused paracentesis. Antibiotics were started with improvement of pain and diarrhea. At discharge, the differential diagnosis was acute gastroenteritis or spontaneous bacterial peritonitis. Final diagnosis: (1) Abdominal pain of the right lower quadrant due to gastroenteritis versus spontaneous bacterial peritonitis, (2) cirrhosis, (3) hemochromatosis. Assign the appropriate codes.

- True
- False
A: True

Q: A 59 year-old female type I diabetic patient presented with a history of fatigue, loss of appetite, and abdominal pain. Hepatomegaly was present on abdominal ultrasound. Liver biopsy was positive for toxoplasma gondii. Clinical signs were also consistent with acute toxoplasmic hepatitis.
