Compliance Question of the Week – Respiratory

Does Medicare have any guidelines related to discharge criteria for patients who have had outpatient respiratory rehab services?

What codes should be used to report outpatient respiratory rehab services that respiratory therapists provide?

Can the following level II code be used for non-COPD patients as well as COPD patients?

What billing tips can you provider for code 94200 (maximum breathing capacity, maximal voluntary ventilation [MVV]), which we often use as a preoperative procedure?

I am looking for guidelines for use of the code below:

94640 Pressurized or nonpressurized inhalation treatment for acute airway obstruction for therapeutic purposes and/or for diagnostic purposes such as sputum induction with an aerosol generator, nebulizer, metered dose inhaler (MDI) or intermittent positive pressure breathing (IPPB) device

I looked up CPT® code 94762—pulse oximetry; continuous overnight determination—in Appendix B of the October 2018 OPPS to find the payment, and I happened to see a SI of Q3 for it. What does this mean?

What codes would be assigned for a six-minute walk test?

What code should be reported for a consult performed by a respiratory therapist in either an outpatient or inpatient setting?

Does Medicare have rules about use of code 94750–pulmonary compliance study (e.g., plethysmography, volume and pressure measurements)?

If multiple spirometric determinations are necessary to complete a service, how many units can be reported?

The answer to the August 20, 2018 Respiratory Compliance Question of the Week mentions that oxygen must be billed as a “measureable” unit. Could you please explain in additional detail whether it would be acceptable to consider measurable as a per-day charge?

What code should be reported when inhalation drugs are administered to an inpatient in a continuous treatment or a series of “back-to-back” treatments exceeding one hour?
