Medical Terminology, ICD-10-CM Diagnosis Coding & Guidelines (Q1–Q10)
Q1. A patient presents with uncontrolled type 2 diabetes mellitus with diabetic chronic
kidney disease stage 3. How should this condition be coded?
A. E11.9 only
B. E11.22, N18.30
C. E11.65 only
D. E10.22, N18.30
Correct Answer: 🔴 B. E11.22, N18.30
,Explanation: 🔹 Type 2 diabetes with diabetic chronic kidney disease requires two codes:
E11.22 for diabetes with CKD and an additional code to identify the stage of CKD
(N18.30 for stage 3 unspecified). The other options are incorrect because E11.9 is
unspecified diabetes, E11.65 is hyperglycemia without complication, and E10 codes
represent type 1 diabetes.
Q2. A patient is diagnosed with acute appendicitis with localized peritonitis. What is
the correct ICD-10-CM coding?
A. K35.80
B. K35.30
C. K35.31
D. K37
Correct Answer: 🔴 C. K35.31
Explanation: 🔹 K35.31 represents acute appendicitis with localized peritonitis and
perforation status unspecified. K35.80 is uncomplicated appendicitis, while K35.30
excludes peritonitis involvement.
Q3. A patient presents with essential hypertension and heart disease. Which coding
approach is correct?
A. I10 only
B. I11.9
C. I11.0, I50.9
D. I13.10
Correct Answer: 🔴 C. I11.0, I50.9
Explanation: 🔹 Hypertensive heart disease with heart failure requires combination code
I11.0 plus a heart failure code such as I50.9. The other options do not fully capture both
conditions.
,Q4. A patient is treated for pneumonia due to Streptococcus pneumoniae. What is the
correct coding?
A. J18.9
B. J13
C. J15.9
D. B95.3 only
Correct Answer: 🔴 B. J13
Explanation: 🔹 J13 specifically identifies pneumonia due to Streptococcus pneumoniae.
J18.9 is unspecified pneumonia, and B95.3 is only a supplementary organism code.
Q5. A patient has chronic obstructive pulmonary disease with acute lower respiratory
infection. What is correct?
A. J44.9
B. J44.0, J22
C. J44.0, J20.9
D. J43.9
Correct Answer: 🔴 C. J44.0, J20.9
Explanation: 🔹 COPD with acute lower respiratory infection requires J44.0 plus an
additional code identifying the infection such as acute bronchitis (J20.9).
Q6. A patient is diagnosed with iron deficiency anemia due to chronic blood loss.
What is correct coding?
A. D50.9
B. D50.0
C. D64.9
D. D51.0
Correct Answer: 🔴 B. D50.0
, Explanation: 🔹 D50.0 is iron deficiency anemia secondary to blood loss (chronic). Other
codes represent unspecified anemia or different etiologies.
Q7. A patient is diagnosed with gastroesophageal reflux disease without esophagitis.
A. K21.0
B. K21.9
C. K22.10
D. K20.9
Correct Answer: 🔴 B. K21.9
Explanation: 🔹 K21.9 is GERD without esophagitis. K21.0 includes esophagitis.
Q8. A patient presents with acute renal failure due to dehydration. What is correct
sequencing?
A. E86.0 only
B. N17.9 only
C. N17.9, E86.0
D. E86.0, N17.9
Correct Answer: 🔴 D. E86.0, N17.9
Explanation: 🔹 Dehydration is the underlying cause and should be sequenced first,
followed by acute renal failure.
Q9. A patient has obesity hypoventilation syndrome.
A. E66.9
B. E66.2
C. J96.10
D. E66.01
Correct Answer: 🔴 B. E66.2
