Screening or Diagnostic Colonoscopy?

All colonoscopies, whether diagnostic or screening, are billed under the CPT/Procedure code 45378.  The diagnosis or reason for the colonoscopy is what determines if the procedure is diagnostic/surveillance or preventative/screening. 
 

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. 


FAQS - Frequently Asked Questions

Q: How long will my procedure take?
A: Plan to spend 2- 2 1/2 hours with us from the time you arrive until when you are released to go home. The procedures themselves are relatively quick.
- An upper endoscopy takes 8-10 minutes, depending on what is found and the need for biopsies.
- A colonoscopy usually takes about 20-25 minutes, again depending on the findings and need for polyp removal, biopsies, etc.
The rest of your stay involves going over the consent prior to the procedure, a physical assessment, taking vital signs, placing an IV and attaching you to a continuous monitor. After the procedure, you will stay under our observation until you are deemed ready to be driven home.
 
Q: Can I drive myself home after the procedure?
A: No. The anesthesia and sedation we use, while relatively short-acting, can have subtle effects for hours after your procedure. Possible drowsiness and delayed reaction times make driving potentially dangerous. Therefore, having someone drive you home is necessary. You may drive and return to normal activities the following day.
 
Q: How soon can I eat and drink after my procedure?
A: Usually immediately after you leave the office, unless you are told otherwise. It is best to avoid heavy meals for that day.
 
Q: Can I take routine medications the day of the procedure?
A: Please do not take any of your medications except those for blood pressure, heart and seizures unless otherwise instructed by your physician.
 
Q: Do I need antibiotics prior to my procedure for an artificial joint?
A: No. The American Society for Gastrointestinal Endoscopy has concluded that antibiotic use for a patient with an artificial joint is not necessary.
 
Q: What happens if I begin to vomit during my prep?
A: Wait 1-2 hours to allow your stomach to settle. Start to drink the solution at a slower pace- every 20-30 minutes. This will take longer but should keep you from vomiting the rest of the solution.
 
Q: I have my period. Can I still have my colonoscopy?
A: Yes. This will not interfere with your procedure. You may use a tampon during the procedure.
 
Q: Do I have to drink all of my prep?
A: Yes. You want your colon completely cleaned out. This allows the physician to find and treat the smallest and flattest polyps.
 
Q: I’m diabetic. What precautions should I take?
A: If you are diabetic, we will give you special instructions. You will need to let us know ALL of your medications and doses. You should check your blood sugars periodically throughout the day of the prep and the procedure. Since you are on clear liquids, your blood sugar will tend to drop faster than normal. To avoid this, be sure to include some liquids with sugar.
 
Q: What if I forget to stop my blood thinners?
A: Please contact the office.
 
Q: Can I take over the counter medications with my prep?
A: Most over the counter medications are acceptable except fish oil, aspirin, Motrin, Advil, ibuprofen, Aleve, naprosyn, naproxen or iron supplements. Tylenol will not interfere with your procedure.
 
Q: Is it OK to drink alcohol?
A: NO! We strongly suggest that you avoid all alcohol before your procedure as it can cause dehydration and may thin your blood.
 
Q: Can I brush my teeth?
A: Yes.
 
Q: Can I chew gum or suck on hard candy?
A: Yes, but no red candy or candy with soft centers. Nothing after midnight.
 
Q: What can I take for a headache?
A: Tylenol or Extra-Strength Tylenol only.

Flexible sigmoidoscopy enables the doctor to carefully examine the rectum and sigmoid colon, and to take tissue from the lining of the colon for a biopsy.

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.

 

 

If polyps are found during the procedure, the doctor may take a tissue sample for biopsy. Some polyps are totally harmless. Others, though benign, may have a small risk of becoming cancerous.

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.

 

Flexible sigmoidoscopy is almost always done on an outpatient basis. The procedure typically takes less than 15 minutes.

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.

Flexible sigmoidoscopy enables the doctor to carefully examine the rectum and sigmoid colon, and to take tissue from the lining of the colon for a biopsy.

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.
