The primary concern of cell division is the maintenance of the original cell's genome. Before division can occur, the genomic information that is stored in chromosomes must be replicated, and the duplicated genome must be separated cleanly between cells. A great deal of cellular infrastructure is involved in keeping genomic information consistent between generations.
Military discharge certificate. In the United States of America, every service member who is discharged or released from active duty is issued a DD Form 214, a military discharge certificate. A reservist who is called up to active duty is given a DD 214 when he or she is deactivated and returned to the reserves.
If the physician admits the patient, but then calls in the discharge order because the patient is better, and the physician does not go to the hospital and see the patient, bill only for codes 99218-99220. Many physicians miss this: if using codes 99234-99236, document two visits and two notes, one for the admission and one for the discharge.
