1 Face-to-face clinical evaluation may include sleep history and symptoms of OSA,
Epworth Sleepiness Scale and physical exam documenting body mass index, neck
circumference and a focused cardiopulmonary and upper airway evaluation. Some of
these elements, in addition to other details, must be documented in patient charts.
2 Medicare-covered sleep tests include Type I, Type II, Type III and Type IV (must monitor
and record a minimum of three (3) channels). All sleep tests must be interpreted by a physi-
cian who is board-certifi ed in sleep medicine by the ABSM, board-certifi ed in sleep medicine
by member board of ABMS, trained in an ABMS member board specialty and is awaiting
exam, or active staff member of an AASM or The Joint Commission accredited sleep center
or lab. (Effective 11/1/08 for Home Sleep Testing and 1/1/10 for Polysomnography)
