Chapter 10: Diseases of the Respiratory System (J00–J99) + Vaping (U07.0) Flashcards
(18 cards)
What does it mean if a COPD or asthma case is labeled “acute exacerbation”?
It means the chronic condition is worsening suddenly, not necessarily due to an infection.
What codes are used for COPD and asthma?
J44 for COPD
J45 for asthma
(With options to show if it’s uncomplicated or an exacerbation.)
True or False: An infection automatically means there is an exacerbation of COPD.
False – Infection can trigger one, but they’re not the same thing.
When do you code acute respiratory failure (J96.0 or J96.2) as the main diagnosis?
When it’s the main reason the patient was admitted.
When do you code respiratory failure as secondary?
If it develops later during the stay or is present on admission but not the main reason for being admitted.
What do you do when a patient has respiratory failure and another acute condition (like a stroke or heart attack)?
Code the main reason for admission first.
If both are equally important, follow Section II, C or ask the provider.
Can you code J09 or J10 based on lab results?
Yes, but it’s not required — a provider’s note is enough.
What’s the difference between J09, J10, and J11?
J09 = Novel or avian flu
J10 = Confirmed flu strain like H1N1
J11 = Suspected/possible flu (not confirmed)
True or False: You can use J09 or J10 even if the doctor only suspects flu.
False – Use J11 if it’s not confirmed.
What is the code for VAP?
J95.851
What must be true to assign J95.851?
The doctor must say the ventilator caused the pneumonia.
Do you code another pneumonia code (like J13–J18) along with VAP?
No – just use J95.851 and the code for the organism (like B96.5).
What is the main code for vaping illness?
A: U07.0
What if VAP develops after regular pneumonia?
Code both:
Original pneumonia = principal diagnosis
VAP = additional diagnosis
Should U07.0 be the primary diagnosis?
Yes, if vaping is the main reason for admission.
What are some related codes you might also add with U07.0?
J96.0- = Acute respiratory failure
J68.0 = Pneumonitis from chemicals
Should you code cough or shortness of breath separately with U07.0?
No – unless no main diagnosis explains them.
Can you code other unrelated symptoms like diarrhea with U07.0?
Yes, you can code other symptoms if they’re not already covered.
