What are Colonoscopy Screening Tests?

A colonoscopy cancer screening test is a medical procedure that is used to screen for or diagnose illness or find precancerous growths. A colonoscopy is done under general anesthesia and the person is asleep.

A colonoscopy is a medical procedure that involves inserting a long, flexible tube into the rectum and large intestine in order to examine the inside of the bowel. The procedure can be used to screen for or diagnose various conditions, such as colorectal cancer, Crohn’s disease, and ulcerative colitis.

It can also be used to remove precancerous growths (polyps) from the bowel lining.

Colonoscopies are generally safe and have a low risk of complications. However, as with any medical procedure, there are some risks involved. These include bleeding, perforation (tearing) of the bowel wall, and infection.

Medicare Coverage for Colonoscopy Screenings

Medicare coverage for colonoscopy screenings is very important for people over the age of 50. This preventative measure can help to detect any early signs of colorectal cancer, which is one of the leading causes of death in America.

Many private insurance companies also offer coverage for this potentially life-saving procedure.

Aside from screening colonoscopy coverage, many Medicare Advantage plans and Medigap plans pay for diagnostic colonoscopy exams.

If you are at risk for developing colorectal cancer your doctor may recommend more frequent testing. Most Medicare Beneficiaries receive a colonoscopy once every 10 years.
