Screening or Diagnostic Colonoscopy?
Diagnostic/Surveillance Colonoscopy:
The patient has past and/or present gastrointestinal symptoms, polyps, GI disease, iron deficiency anemia and/or any other abnormal tests OR the patient is currently asymptomatic (no gastrointestinal symptoms either past or present) but has a personal history of GI disease, personal and/or family history of colon polyps and/or colon cancer. Patients in this category are required to undergo colonoscopy surveillance at shortened intervals (e.g. every 2-5 years).
Insurance plans process these claims subject to the individuals deductible and co-insurance requirements.
Preventative Screening Colonoscopy:
The patient is asymptomatic (no gastrointestinal symptoms either past or present), age 50 or greater, has no personal or family history of GI disease, colon polyps, and/or cancer. The patient has not undergone a colonoscopy within the last 10 years.
Insurance plans usually process these claims under the wellness benefit, payable at 100% if it is a benefit of the individual’s health insurance plan.
Frequently asked questions:
Who will bill me?
You may receive bills for your procedure from the physician, the facility, anesthesia, pathologist and/or laboratory.
Can the physician change, add, or delete my diagnosis so that my procedure can be considered a preventative/wellness/routine screening?
NO! The patient encounter is documented as a medical record from the information you have provided, as well as what is obtained during our pre-procedure history and assessment. It is a binding legal document that cannot be changed to facilitate better insurance coverage.
What if my insurance company tells me that the doctor can change, add or delete a CPT or diagnosis code?
This happens a lot. Often the representative will tell the patient that if the “doctor had coded this as a screening, it would be paid at 100%." A member services representative should never suggest a physician alter a medical record for billing purposes.

What is flexible sigmoidoscopy?
Flexible sigmoidoscopy lets your doctor examine the lining of the rectum and a portion of the colon (large intestine) by inserting a flexible tube about the thickness of your finger into the anus and slowly advancing it into the rectum and lower part of the colon.
What preparation is required?
Your doctor will tell you what cleansing routine to use. In general, preparation consists of one or two enemas prior to the procedure but could include laxatives or dietary modifications as well. However, in some circumstances your doctor might advise you to forgo any special preparation. Because the rectum and lower colon must be completely empty for the procedure to be accurate, it is important to follow your doctor's instructions carefully.

Should I continue my current medications?
Most medications can be continued as usual. Inform your doctor about medications that you're taking, particularly aspirin products, anti-coagulants (blood thinners such as warfarin or heparin), or clopidogrel, as well as any allergies you have to medications.
What can I expect during flexible sigmoidoscopy?
Flexible sigmoidoscopy is usually well-tolerated. You might experience a feeling of pressure, bloating or cramping during the procedure. You will lie on your side while your doctor advances the sigmoidoscope through the rectum and lower part of the colon. As your doctor withdraws the instrument, your doctor will carefully examine the lining of the intestine.

What if the flexible sigmoidoscopy finds something abnormal?
If your doctor sees an area that needs further evaluation, he or she might take a biopsy (tissue sample) to be analyzed. Obtaining a biopsy does not cause pain or discomfort. Biopsies are used to identify many conditions, and your doctor might order one even if he or she doesn't suspect cancer. If your doctor finds polyps, he or she might take a biopsy of them as well. Polyps, which are growths from the lining of the colon, vary in size and types. Polyps known as "hyperplastic" might not require removal, but other benign polyps known as "adenomas" have a small risk of becoming cancerous. Your doctor will likely ask you to have a colonoscopy (a complete examination of the colon) to remove any large polyps or any small adenomas.

What happens after a flexible sigmoidoscopy?
Your doctor will explain the results to you when the procedure is done. You might feel bloating or some mild cramping because of the air that was passed into the colon during the examination. This will disappear quickly when you pass gas. You should be able to eat and resume your normal activities after leaving your doctor's office or the hospital, assuming you did not receive any sedative medication.
What are possible complications of flexible sigmoidoscopy?
Flexible sigmoidoscopy and biopsy are safe when performed by doctors who are specially trained and experienced in these endoscopic procedures. Complications are rare, but it's important for you to recognize early signs of possible complications. Contact your doctor if you notice severe abdominal pain, fevers and chills, or rectal bleeding. Note that rectal bleeding can occur several days after the exam.
