If you think you know 97001-97004 backward and forward you may be surprised that you should avoid using E/M codes for physical therapists (PTs) and occupational therapists (OTs). However you can report 97001-97004 in addition to a separate E/M service on the same day.
Sponges do have several distinct types of cells, each with different functions. (See FIG.) The body wall of a sponge is perforated by numerous pores or ostia through which water is drawn into a central cavity called the spongocoel or central cavity. The osculum is a large opening at one end of the sponge through which all the resulting excurrent is evacuated.
The lungs are a pair of spongy organs located inside the chest. They are the main part of our respiratory system. Their function is to deliver oxygen into the blood and to remove carbon dioxide from it. When we breathe in, air rushes through our nose or mouth, down the windpipe (trachea) and into the lungs.
