, 2026 Inpatient Coding Exam: Practice Questions & Answers
Instructions: Select the best answer for each of the following questions based on the current
Inpatient Coding Guidelines.
1. According to the UHDDS, how is the principal diagnosis defined?
a) The diagnosis that is most expensive to treat.
b) The condition present on admission that has the highest mortality rate.
c) That condition established after study to be chiefly responsible for occasioning the admission
of the patient to the hospital for care.
d) The final diagnosis listed on the discharge summary.
Answer: c) That condition established after study to be chiefly responsible for occasioning the
admission of the patient to the hospital for care.
Explanation: The Uniform Hospital Discharge Data Set (UHDDS) provides the official
definition for the principal diagnosis, which is the foundation for all principal diagnosis
selection. It emphasizes that the determination is made after study and is focused on the reason
for the admission.
2. A patient is admitted with severe abdominal pain. After a comprehensive workup, the physician
definitively diagnoses acute cholecystitis. How should the abdominal pain be coded?
a) As the principal diagnosis
b) As a secondary diagnosis only
c) It should not be coded at all
d) Only if the pain persists after treatment
Answer: b) As a secondary diagnosis only
Explanation: Guidelines state that codes for symptoms, signs, and ill-defined conditions from
Chapter 18 (of ICD-10-CM) are not to be used as a principal diagnosis when a related definitive
diagnosis has been established. The definitive diagnosis (acute cholecystitis) becomes the
principal diagnosis, and the symptom (abdominal pain) can be reported as an additional
diagnosis if it was part of the clinical evaluation.
