Each Marked out of class received a different diet program to follow. The weight, age and sex of each patient are recorded at the beginning 1.00 and end of the 10-week program. The average weight loss for each class is also calculated at the end of the 10-week P Flag question program. In...

2) In a different study, patients were divided randomly into two groups. One group received a well-known migraine headache medication called Maxalt, while another group received nothing. On average, there was a 40% decrease in pain levels after 2 hours for the group receiving Maxalt. The group who received nothing had a 15% decrease in pain. Part A: The patients were divided randomly, so the groups should be roughly similar. Unfortunately, there is still a confounding variable in this study....

4) A pair of studies was performed to measure the effectiveness of a new software program designed to help stroke patients regain their problem-solving skills. Patients were divided randomly into two groups. One group was asked to use the software program twice a day, once in the morning and once in the evening. Their progress was recorded and compared with the group that did not use the software. a) Is this an observational studies or an experiment? If it is...

You are a new medical coder that works for an Orthopedic medical practice. Patients are often seen for fractures or dislocations which require either a cast or splint. A common patient encounter may be for application of a long-arm split. Apply your knowledge of CPT to this patient scenario. Include the following aspects in the assignment: Ø Describe what a long-arm splint is and when this would be appropriate Ø Provide the CPT code from the Surgery section which would identify application...
