Compliance Question of the Week – Respiratory

What code should be reported when an exercise test is done to diagnose bronchospasm?

Is there a CPT® code for non-invasive ventilation?

Can we separately report endoscopic procedures that are performed on two regions of the respiratory system with different types of endoscopes?

What are the OPPS rates for new codes 94617 and 94618 for exercise and stress testing?

For 2018, should we continue to use 94620 for pulmonary stress testing?

Can a biopsy code (i.e., CPT® code 31237 for nasal/sinus endoscopy) be reported with the removal nasal/sinus endoscopy code (i.e., CPT code 31255)?

Would the documentation of snoring and signs of nasal obstructions be enough reason to do a polysomnography?

In 2018, will 94620 still the code to assign for pulmonary stress testing?

If an endoscopic anterior ethmoidectomy is performed, can the diagnostic nasal endoscopy be reported separately?

How many naps must be recorded to report MLST or MWT?

My question relates to the answer to last week’s question about assigning modifier 52 to the code for an incomplete polysomnography (PSG) with CPAP titration. To use this modifier, is there a time requirement for the CPAP?

Would modifier 52 be appropriate when the physician orders polysomnography with CPAP titration, and during the phase of the test using the CPAP, the patient is physically unable to complete this portion of the test (e.g., adverse event)?
