Compliance Question of the Week – Respiratory

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)?

How should a split-night study be coded? Can the diagnostic portion and titration portion of a single study be billed separately?

What code is used for home-ventilation management services?

To follow-up on last week’s Q&A re: billing vent management in the ED, how is this billed if provided in skilled nursing facilities (SNFs)?

How should vent management in the ED be billed?

Does Medicare have a frequency limit on use of code 94750—pulmonary compliance study (e.g., plethysmography, volume and pressure measurements)?
