Medical examinations for preventative purposes could vary by as much as 700 percent, according to a report from Change Healthcare.

The number of wellness exams for Americans paid by health plans and employers has increased, and they have been available without extra charges. These exams are for diabetes, mammograms, colonoscopies, pap smears and other preventative tests, the report noted. The price differences are for many reasons, such as where a person lives, if the procedure is done in a hospital, a clinc or another venue and if a place specializes in the procedure.

"I wasn't surprised that there was variability, but the degree of variability surprised me," Doug Ghertner, president of Change Healthcare, told USA Today. "The absolute dollars for colonoscopies were pretty big."

Currently, healthcare companies are looking for ways to lower the costs, overall, the report added.

Consumers who are concerned about paying too much for their healthcare payments may want to look for another policy. With the plethora of affordable health insurance rates available, a person may be able to find the plan that fits their needs.
