Domain I: Healthcare Regulations, Reimbursement & IPPS (15-20% of exam)
Q1. Under the Inpatient Prospective Payment System (IPPS), what is the
primary factor that determines a hospital's reimbursement for a Medicare
patient?
• A) The total number of days the patient stayed in the hospital
• B) The specific procedures performed, ranked by resource cost
• C) The assigned MS-DRG, based on diagnoses and procedures
• D) The patient's out-of-pocket deductible and coinsurance
Correct ,,,answer,,,: C
Rationale: Under IPPS, hospitals are reimbursed a predetermined fixed amount
based on the assigned Medicare Severity Diagnosis Related Group (MS-DRG).
The MS-DRG is determined by the principal diagnosis, up to 25 secondary
diagnoses, and major procedures performed . Length of stay influences costs but
not the base reimbursement rate.
,Q2. A patient is admitted with chest pain and found to have an acute ST-
elevation myocardial infarction (STEMI) of the anterior wall. What is the role
of the principal diagnosis in this admission?
• A) It identifies the condition that was most resource-intensive to treat
• B) It identifies the condition that was present on admission and led to the
inpatient stay
• C) It identifies the chronic condition with the highest long-term mortality
risk
• D) It identifies the first diagnosis documented by the ED physician
Correct ,,,answer,,,: B
Rationale: The principal diagnosis is defined as "the condition, after study, which
occasioned the admission to the hospital" (Uniform Hospital Discharge Data Set).
Chest pain is a symptom; the confirmed STEMI is the final principal diagnosis
because it is the reason for admission after study .
Q3. A patient is admitted for elective total knee arthroplasty. On post-
operative day 2, the patient develops acute hypoxic respiratory failure
requiring BiPAP. The physician documents "acute respiratory failure." How
does this impact the MS-DRG?
• A) No impact, as respiratory failure is expected after surgery
• B) It may change the DRG only if the patient requires intubation
• C) It may increase the MS-DRG weight if the respiratory failure is a CC or
MCC
• D) It will decrease reimbursement because it prolongs length of stay
Correct ,,,answer,,,: C
,Rationale: The MS-DRG system assigns higher weight (reimbursement) to
patients with Complications (CCs) or Major Complications (MCCs). Acute
respiratory failure requiring non-invasive ventilation typically qualifies as an MCC
or CC, potentially shifting the case to a higher-weighted DRG .
Q4. Which of the following correctly distinguishes a
Complication/Comorbidity (CC) from a Major Complication/Comorbidity
(MCC)?
• A) CCs are always present on admission; MCCs always develop during
hospitalization
• B) MCCs have a higher relative weight and indicate a more severe impact on
resource utilization
• C) CCs are assigned only to surgical patients; MCCs only to medical
patients
• D) There is no difference; the terms are interchangeable for DRG
assignment
Correct ,,,answer,,,: B
Rationale: MCCs represent the most severe secondary diagnoses (e.g., acute
respiratory failure with mechanical ventilation, septic shock). CCs represent less
severe but still impactful conditions. Both affect DRG assignment, but MCCs shift
the case to a higher-weighted DRG tier with significantly higher reimbursement .
Q5. A 72-year-old patient is admitted for an acute exacerbation of COPD.
During the stay, the patient develops hospital-acquired pneumonia (HAP)
, requiring IV antibiotics. The pneumonia was not present on admission. Under
MS-DRGs, how should the CDI specialist approach this?
• A) The pneumonia should be coded as a secondary diagnosis and may affect
the DRG as a CC/MCC
• B) The pneumonia cannot be coded because it is a hospital-acquired
condition (HAC)
• C) The pneumonia should replace COPD as the principal diagnosis
• D) The pneumonia should not be documented as it will trigger a RAC audit
Correct ,,,answer,,,: A
Rationale: Hospital-acquired conditions (HACs) that are present on admission are
not subject to payment reduction if they meet specific coding guidelines. However,
HAP may still be coded as a secondary diagnosis. However, specific HACs (like
certain infections) may impact reimbursement through the HAC Reduction
Program. The key is that the pneumonia should be coded if it is clinically
significant and treated .
Q6. What is the "Two-Midnight Rule" in the context of inpatient admissions?
• A) Patients must be admitted before midnight to qualify for same-day
surgery benefits
• B) Inpatient admission is generally appropriate when the physician expects
the patient to require a stay spanning two midnights
• C) All elective surgeries must be scheduled at least two midnights prior to
the procedure
• D) Observation status cannot exceed two midnights under any circumstances
Correct ,,,answer,,,: B
