Last year, when you were hired as the HIM director at a small community hospital, the CEO wanted you to focus on increasing the case mix index. The hospital base rate is $7,862. At the time you came on board, there were three coders, only one of whom was a certified coding specialist (CCS). You began by reviewing the number of MS-DRGs submitted over the past year. The MS-DRG that jumped out was MS-DRG 304, which is hypertension with an MCC. There were 53 submissions of this MS-DRG. As you reviewed the data for 10 of those submissions, you began to notice a trend. Evaluate the data below to identify the issue Chart Codes submitted

Continue using the same information from above
After review of all 53 cases in MS-DRG 304, you determined that 46 of them had the same error.
Correcting the errors results in reassignment of those cases to a different MS-DRG. Calculate the impact this has on reimbursement by determining the relative weight of the two MS-DRGs and performing the calculations to determine the reimbursement difference.

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

  suspension

suspension is used to   center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a   loudspeaker, a   thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates   and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to   determine how energy which is   travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to   voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.
