With the advent of PDPM October 1st, 2019, questions regarding the delivery and coding of respiratory therapy services is top of everyone’s list of question.

The coding of the Respiratory Therapy on the MDS requires:

  • Respiratory Therapy 7 days a week
  • At least 15 minutes per day
  • Equivalent to 5 minutes per shift (105 minutes total/week)

Harmony Healthcare International (HHI) reinforces the Importance of documenting the nurse clinical assessments of the patient's respiratory status to accurately depict the minutes rendered per shift.  This includes a focused physical assessment of the respiratory status which includes assessing and obtaining patients oxygen saturation, assessing any use of oxygen and flow volume to maintain oxygen saturations. 

According to the RAI User’s Manual (page O-140)

For purposes of the MDS, providers should record services for respiratory, psychological, and recreational therapies (Item O0400D, E, and F) when the following criteria are met:

  • the physician orders the therapy;
  • the physician’s order includes a statement of frequency, duration, and scope of treatment;
  • the services must be directly and specifically related to an active written treatment plan that is based on an initial evaluation performed by qualified personnel (See Glossary in Appendix A for definitions of respiratory, psychological and recreational therapies);
  • the services are required and provided by qualified personnel (See Glossary in Appendix A for definitions of respiratory, psychological and recreational therapies);
  • the services must be reasonable and necessary for treatment of the resident’s condition.

In Appendix A (page Appendix A-18), the following definition is provided as to what is considered Respiratory Therapy:

"Services that are provided by a qualified professional (respiratory therapists, respiratory nurse). Respiratory therapy services are for the: 

  • assessment,
  • treatment, and
  • monitoring of

    patients with deficiencies or abnormalities of pulmonary function. Respiratory therapy services include coughing, deep breathing, heated nebulizers, aerosol treatments, assessing breath sounds and mechanical ventilation, etc., which must be provided by a respiratory therapist or trained respiratory nurse. Does not include hand-held medication dispensers."

Because the RAI User’s Manual does not specifically define a “Respiratory Nurse,” Harmony Healthcare International (HHI) recommends that the facility seek guidance from the State Practice Act in their respective state and review that nurses are practicing:

  1. According to scope of practice as defined by the State Specific Board for Nursing.
  2. According to Facility Policy.

New call-to-action

In addition to the above details, Harmony Healthcare International (HHI) reiterates the importance of what constitutes a day of treatment

On page O-24 of the RAI User’s Manual, the following example is given to reinforce the need of 15 minutes or more of respiratory therapy in a 24-hour period To accurately code on the MDS, there must be a “Day” of Respiratory Therapy. 


  • Respiratory therapy services that were provided over the 7 day look back period.
  • Respiratory therapy services provided Sunday-Thursday for 10 minutes each day.


  • O0400D1 would be coded 50, O0400D2 would be coded 0.


  • Total minutes were 50 over the 7 day look back period (10 × 5 = 50).

Although a total of 50 minutes of respiratory therapy services were provided over the 7-day look back period, there were not any days that respiratory therapy was provided for 15 minutes or more. Therefore, O0400D equals zero days.
