Medical Coding for Stress can be Physical or Chemical. So a stress test can be performed in several different ways. The key is to get the heart pumping and accelerate the heart and then graph it to see what its doing. So to create stress on the heart orâ¦ in the heart, theyâll use a treadmill, or exercise bike. Thereâs more than one type of treadmill thatâs listed on the CPT code 93015, just in case when youâre reading the case and thereâs a specific type of treadmill. Another way that they can do this is by medication.
The causes of climate change can be divided into two categories-those that are due to natural causes and those that are created by man. Natural causes There are a number of natural factors responsible for climate change. Some of the more prominent ones are continental drift, volcanoes, ocean currents, the earth's tilt, and comets and meteorites. Let's look at them in a little detail.
Other human activities include agriculture and changes in land-use patterns. They all work to tip the Earthâs energy balance by trapping more heat. Even scientists who think human activity is the main cause of climate change don't deny that natural changes will cause temperature fluctuations on Earth. However, their argument is that in the current cycle of climate change, the impact caused by man is far greater.
