What is hypoxia, and what code would be reported for it?


Disorders typically diagnosed by this sleep study include the following:

Hypoxia is a state of oxygen deficiency in the body that is enough to cause an impairment of function. The condition is caused by the reduction in partial pressure of oxygen, inadequate oxygen transport, or the inability of the tissues to use oxygen. During the hypoxic challenge, patients breathe in a reduced concentration of oxygen. Hypoxia is assessed through oxygen saturation measurements to identify those patients requiring supplemental oxygen. Report the following code:

94450 Breathing response to hypoxia (hypoxia response curve)
