A20 year-old patient presented to the hospital with a history of bloody stools for three weeks' duration. the patient was prepped for a sigmoidoscopy. the sigmoidoscope was passed without difficulty to about 40 cm. the entire mucosal lining was erythematosus. there was no friability of the overlying mucosa and no bleeding noted. no pseudo polyps were identified. biopsies were taken at about 30 cm; these were thought to be representative of the mucosa in general. the scope was retracted; no other abnormalities were seen. what cpt® and icd-10-cm codes are reported?

The answer is 45331, K92.1. CPT® code for a sigmoidoscopy with single or various biopsies is accounted for 45331. This is recorded under Sigmoidoscopy/Biopsy. Symptomatic sigmoidoscopy is constantly packaged with a surgical sigmoidoscopy when both are performed in a similar agent session. The ICD-10-CM code for bleeding stools is found in the Index to Diseases and Injuries under Blood/in/defecation or Hematochezia or Melena and coded K92.1. At the point when a patient comes in with a GI side effect and no conclusive analysis is reported for the indication.

Mantle convection  is the slow  creepingmotion of earth's solid silicate  mantle  caused by  convection  currents carrying  heat from the interior  to the planet's surface.[1][2]  the earth's surface  lithosphere, which rides atop the  asthenosphere  (the two components of the  upper mantle), is divided into a number of  plates  that are continuously being created and consumed at their opposite  plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with  seafloor spreading. this hot added material cools down by  conduction  and  convection  of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of  subduction  usually at an  ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4]  while in other regions, this material is impeded from sinking further, possibly due to a phase transition from  spinel  to  silicate perovskiteand  magnesiowustite, an  endothermic reaction.[5]the subducted oceanic crust triggers  volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6]  and  mantle plumes.[7]it is because the mantle can convect that the  tectonic plates  are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the  hadean  period, resulting in gravitational sorting of heavier molten  iron, and  nickel  elements and  sulphides  in the core, and lighter  silicate minerals  in the  mantle.

It was said to have happened by earthquakes, the shifts in the tectonic plates moved everything
