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.
In addition to filtering blood through pulp-like tissue, the spleen also houses two very important types of immunity-related white blood cells: lymphocytes and phagocytes. Some of the spleenâs other functions include: Cleaning impurities from the blood. Destruction and removal of old red blood cells.
