I’m working on trying to get all of our items we collect within the “Vitals” area of our product with LOINC codes. This is the one that I’m having the hardest time finding something for.
From our client request for it: “<span style=“background-color: #ffffdd; font-family: Verdana, sans-serif; font-size: 12px;”>Oxygen Requirement - it is needed to complete our CMNs (Certificate of Medical Necessity) for home oxygen use. A physician’s certification of medical necessity for oxygen equipment must include the results of specific testing before coverage can be determined. Claims for oxygen must also be supported by medical documentation in the patient’s record. Separate documentation is used with electronic billing. This documentation may be in the form of a prescription written by the patient’s attending physician who has recently examined the patient (normally within a month of the start of therapy) and must specify: A diagnosis of the disease requiring home use of oxygen”</span>
The parts of this are:

I’m not seeing as many good things for frequency or duration of use/need. I see a simplified one based on the answer list here: https://loinc.org/88658-0 , although answer lists are always “optional”, it seems like maybe that could be used as a good code for their second part?
