Coverage for oxygen and oxygen equipment is dependent upon the presence of conditions that cause chronic hypoxemia. When the underlying condition is in the chronic stable state, blood oxygen testing may be performed by a qualified provider of laboratory services to evaluate the degree of hypoxemia.
A work in progress-new features will be added periodically. The trombone glissando is an idiomatic and frequently used technique that is often misunderstood.
