Instructions: Read the mini-medical-record, then answer the questions
that follow to abstract, assign, and arrange (sequence) the
correct
codes.
Part 1: Abstract
1. Read through the mini-medical-record. Observe the patient
demographics. Compare the chief complaint to the final
assessment.
a. What symptom did the patient report in the chief complaint?
b. What two conditions are stated in the assessment?
2. a. Is the symptom integral to one of the conditions stated in
the assessment?
b. Should you code for the symptom?
c. Why or why not?
d. What is the first condition due to?
Part 2: Assign
3. You can look up the conditions in any order you wish, as long
as you sequence them correctly in the end based on the
instructional notes you find during this exercise.
Today, begin by coding the underlying condition, the condition
that the heart failure is due to
.
a. Look up the Main Term Hypertension in the Index, then

the subterm heart, with, heart failure
. What code is
listed?
b. Verify this code in the Tabular List. Is there a symbol in front
of this code indicating that you need additional characters?
4. a. What does the instructional note under the code say?
b. Based on this instructional note, should the code for
Hypertension be sequenced first or second?
5. a. Locate the beginning of this block for Hypertensive
diseases
.
Read the instructional notes. Now refer
back to the mini-medical-record. What lifestyle habit is
documented?
b. Which instructional note applies to this patient? (
Tip:
History
describes a past condition that no longer exists.)
You will verify this code later in this exercise.
c. Review the instructional notes at the beginning
of ICD-10-CM Chapter 9. Do any of these notes apply
to this patient?
6. a. Now determine the code for heart failure. Look again at the
instructional note under the code for Hypertension
. What
code is listed in the instructional note?
b. What does the short dash (-) at the end of the code mean?
7. a. Verify the code listed in the instructional note. Review the
four-character subcategories under this heading and locate
the one that describes Combined systolic and diastolic
heart failure
. Write down the subcategory code.
b. Now review the five-character codes under this
subcategory.
What code describes Chronic combined
systolic and diastolic heart failure
?
8. Cross-reference the three-character category heading for
Heart failure
. Read through the instructional notes. What
condition should be coded first that applies to this patient.
This code should match the one you assigned in step 3a.
The instructional note confirms that you assigned the correct
first code or alerts you to the fact that the first code was not
correct.
9. Now you need to assign a third code for the lifestyle habit you
listed in step 5a above. List the code here.
Verify the code. (This code is sequenced last.)
Part 3: Arrange
10. You have identified three codes for this case. Review your
answers in the previous questions to determine the correct
sequencing.
a. What code is sequenced first based on the instructional
notes in steps 4b and 8?
b. What code is sequenced second?
c. What code is sequenced third?
