CCDS Respiratory Failure & Vents 3

Question 1

A patient with acute exacerbation of COPD is placed on BiPAP in the ED and admitted to the ICU.
Arterial blood gas shows pH 7.28, PaCO2 58, PaO2 54.
Which diagnoses should be queried for in this scenario?

Accepted Answer

Acute-on-chronic respiratory failure (hypercapnic) and COPD exacerbation

Answer

COPD exacerbation only; BiPAP use does not require additional diagnosis documentation

Answer

Acute hypoxic respiratory failure and community-acquired pneumonia

Answer

Acute respiratory distress syndrome (ARDS) given the hypoxia

Question 2

A CDI specialist reviews a case where a patient is extubated successfully on day 3 of mechanical ventilation. The physician documents 'respiratory failure, resolved.' The CDI specialist should:

Accepted Answer

Query to specify the type and chronicity (acute hypoxic, hypercapnic, or acute-on-chronic)

Answer

Code only J96.90 (unspecified respiratory failure) since it resolved

Answer

Not code respiratory failure since it resolved before discharge

Answer

Code the MV procedure only and omit the respiratory failure diagnosis

Question 3

Ventilator-associated pneumonia (VAP) requires documentation of which minimum timeframe on mechanical ventilation before pneumonia onset?

Accepted Answer

Pneumonia developing more than 48 hours after initiation of mechanical ventilation

Answer

Pneumonia present within 24 hours of intubation

Answer

Pneumonia developing more than 72 hours after intubation in the ICU

Answer

Any pneumonia in a mechanically ventilated patient regardless of timing

Question 4

In ICD-10-PCS, which structural feature distinguishes Section 5 ventilation codes from Section 0 medical and surgical codes?

Accepted Answer

Section 5 uses Duration and Function characters instead of a standard Approach character

Answer

Section 5 uses a standard Approach character like Section 0

Answer

Section 5 codes have only 5 characters instead of 7

Answer

Section 5 requires a separate device character for the ventilator brand

Question 5

A CDI specialist notices that a patient with acute respiratory distress syndrome (ARDS) is documented only as 'bilateral pneumonia' by the attending. What clinical documentation would BEST support querying for ARDS?

Accepted Answer

Berlin criteria: acute onset within 7 days, bilateral infiltrates not fully explained by cardiac failure, and P/F ratio 300 or below despite PEEP at or above 5 cm H2O

Answer

Fever and bilateral lung infiltrates on chest X-ray only

Answer

Mechanical ventilation requirement regardless of P/F ratio or imaging findings

Answer

SpO2 below 88% on room air at any point during the hospitalization

Question 6

Which clinical scenario BEST illustrates the difference between 'respiratory arrest' (R09.2) and 'acute respiratory failure' (J96.0x) in ICD-10-CM?

Accepted Answer

Respiratory arrest indicates complete cessation of breathing requiring resuscitation; acute failure indicates compromised gas exchange not necessarily requiring CPR

Answer

Respiratory arrest is used for patients who required intubation; acute failure is for non-intubated patients

Answer

Respiratory arrest is the sequela after acute failure has been treated

Answer

The terms are interchangeable and either code may be used based on coder preference
