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.
The expected changes in climate are based on our understanding of how greenhouse gases trap heat. Both this fundamental understanding of the physics of greenhouse gases and fingerprint studies show. that natural causes alone are inadequate to explain the recent observed changes in climate.
