From FOBT to screening barium enemas, know how to report these services. Your gastroenterologist is likely to perform multiple colonoscopies each week, but those probably aren’t the only colorectal screening services he or she performs. To ensure that you collect appropriately for all of these screenings, get the lowdown on Medicare’s rules and know which codes apply. Check out the following four tips before you turn in your next screening claim. Step 1: Pinpoint Screening Frequency Rules Medicare reimburses multiple procedures for the early detection of cancer. The frequency restrictions for these tests depend on the patient’s risk category. Check the following list for deciding eligibility for average risk/asymptomatic patients (beginning at age 50 years): 1. Between 50 and 85 years of age. 4. They have no family history of colorectal cancers or adenomatous polyps, familial adenomatous polyposis, or hereditary nonpolyposis colorectal cancer. The frequency rules for high-risk patients (No age restriction) are: One other option listed in some places as a primary screening test is computed tomography colonography (CTC). However, virtual CT is not indicated for primary screening. For Medicare, it may be covered under certain condition such as failed optical colonoscopy or some severe co-morbid health conditions. Exception: Other than the tests mentioned above, physicians may also order one of the following tests for screening. However, these are non-covered colorectal cancer screening tests: 1. Magnetic resonance imaging (MRI) colonography is considered experimental and investigational for the screening or diagnosis of colorectal cancer, inflammatory bowel disease, or other indications because its value for these indications has not been established. 2. Wireless Capsule Endoscopy (WCE) -- WCE (i.e. PillCamTM) is accomplished by encasing video, illumination and transmission modules inside a capsule the size of a large vitamin pill. WCE is NOT a covered benefit for general screening. 3. Virtual Colonoscopy or CT Colography – Several states have their own rules about coverage of CT colography for non-Medicare patients so you may need to check your own state’s rules to determine if this test is covered for primary colorectal cancer screening. 4. Septin 9™ blood test Step 2: Identify ICD-10 Codes That Support Risk Although all patients above 50 years of age are eligible for colorectal cancer screening tests even in absence of any symptoms, a patient must fall into the high-risk category for colorectal cancer to qualify for a screening colonoscopy or screening barium enema before age 50. For a patient to be classified as high risk, you have to use a certain diagnosis. You won’t get paid just because the patient has colorectal cancer screening as a benefit. To be reimbursed for the screening, check the gastroenterologist’s notes for an accepted diagnosis code denoting the high-risk status of the patient with the procedure code. The following ICD-10 codes are some examples of diagnoses that meet the high-risk criteria for colorectal cancer: Other than these primary diagnoses, some secondary diagnoses from among the following family of diagnostic codes may also apply: The final determination of an appropriate diagnosis for being at high risk has been left with the local Medicare contractors, however, and the codes that each one will accept can vary significantly, says Glenn D. Littenberg, MD, MACP, FASGE, AGAF, a gastroenterologist and former CPT® Editorial Panel member in Pasadena, California. Step 3: Pick the Proper Screening HCPCS Code In addition to using the correct diagnosis code, gastroenterologists should bill their Medicare claims for asymptomatic patients with the proper HCPCS code for the specific screening service provided. You should use the following HCPCS codes with Medicare claims for colorectal cancer screening services for high-risk patients: - G0104 -- Colorectal cancer screening; flexible sigmoidoscopy; When billing a colorectal cancer screening test for an average/ no risk individual, you should choose from these two HCPCS codes: - G0121 -- Colorectal cancer screening; colonoscopy on individual not meeting criteria for high risk Gastroenterologists should use G0121 when the patient fits the once every 10-year interval and should not be surprised to see a Medicare denial if the prior colonoscopy was less than nine years 11 months prior. In that case, the physician may not be able to bill the patient for the service unless an Advanced Beneficiary Notice was obtained. Cologuard™ is only billed under CPT® code81528, but the billing comes from the company which markets the kit, not from the physician’s office; the physician provides a “prescription” (form to fill out as a lab order) and the company then acts on the order and ultimately provides a report to the ordering physician, Littenberg says. Step 4: Separate Screening From Diagnostic Services You should never report colorectal screening services with the codes that apply to diagnostic services. The HCPCS codes are used when the patient is asymptomatic, regardless of whether he or she is at high risk for colorectal cancer. If the patient comes in with a symptom such as blood in stool and the gastroenterologist performs a colonoscopy, then you should bill the appropriate sigmoidoscopy or colonoscopy procedure codes 45330 (Sigmoidoscopy, flexible; diagnostic, including collection of specimen[s] by brushing or washing, when performed [separate procedure]) or 45378 (Colonoscopy, flexible; diagnostic, including collection of specimen[s] by brushing or washing, when performed [separate procedure]) for the diagnostic service. Likewise, fecal-occult blood tests for diagnostic evaluation of symptomatic patients should be billed using the CPT® code 82274 (Blood, occult, by fecal hemoglobin determination by immunoassay, qualitative, feces, 1-3 simultaneous determinations). If the GI converts a screening test into a diagnostic endoscopy due to abnormal findings, you should bill the appropriate CPT® code with modifier PT (Colorectal cancer screening test; converted to diagnostic test or other procedure) instead of the screening code (for non-Medicare payers, the equivalent is modifier 33). Gastroenterologists also should ensure that patients referred to them for colorectal screenings are actually asymptomatic. Many times patients are referred for a screening when they really have symptoms, and those procedures should be coded as diagnostic.

2. They show no signs or symptoms of colorectal disease including, but not limited to, lower gastrointestinal pain, blood in stool, positive guaiac fecal occult blood test, or fecal immunochemical test.
3. They’re at average risk for developing colorectal cancer, meaning they have no personal history of adenomatous polyps, colorectal cancer, or inflammatory bowel disease, including Crohn’s Disease and ulcerative colitis.
