Serum Antibodies for the Diagnosis of Inflammatory Bowel Disease
Policy Number: MP-285
Latest Review Date: October 2019
Category: Medical Policy
The use of serologic markers is considered not medically necessary and investigational for all indications, including but not limited to:
- anti-neutrophil cytoplasmic antibodies (ANCA)
- anti-Saccharomyces cerevisiae (ASCA)
- antibodies of outer membrane porin C of the bacteria Eschericia coli (anti-OmpC)
- Pseudomonas fluorescens-associated sequence I2 (anti-I2)
- flagellin CBir1 (anti-cBir1)
- antichitobioside antibodies (ACCA IgA)
- antilaminaribioside antibodies (ALCA IgG)
- antimannobioside antibodies (AMCA IgG)
DESCRIPTION OF PROCEDURE OR SERVICE:
Inflammatory bowel disease (IBD) can be subdivided into ulcerative colitis (UC) and Crohn’s disease (CD), both of which present with symptoms of diarrhea and abdominal pain. The definitive diagnosis can usually be established by a combination of radiographic, endoscopic, and histologic criteria, although in 10%–15% the distinction between ulcerative colitis and Crohn’s disease cannot be made with certainty. Two serum antibodies, anti-neutrophilic cytoplasmic antibodies (ANCA) and anti- Saccharomyces cerevisiae (ASCA) have been associated with IBD; however, they have low sensitivities and are not completely specific to the disease. A number of subtypes of these markers have also been identified based on the specific antigen that is targeted. Testing for ANCA is currently available in most clinical laboratories. ASCA is a more recent assay that is becoming more widely available, but the reliability of testing for ASCA among different labs may be more variable as compared to ANCA.
These serum antibodies have several potential uses. They can be used as diagnostic tests to improve the efficiency and accuracy of diagnosing IBD to decrease the extent of the diagnostic workup or to avoid invasive tests. As a diagnostic test, they might also be useful in differentiating between UC and CD in cases of indeterminate colitis. A second potential use is to classify subtypes of IBD by location of disease (i.e., proximal versus distal bowel involvement) or by disease severity, thereby providing prognostic information. It has also been proposed that these markers may predict response to anti-tumor necrosis factor (TNF) therapy or identify susceptibility to IBD among family members of an affected individual.
The Prometheus system is a commercially available diagnostic system that uses combinations of tests for anti-neutrophil cytoplasmic antibody (ANCA) and/or anti- Saccharomyces cerevisiae antibody (ASCA) to aid in the diagnosis of Inflammatory Bowel Disease (IBD). Tests/test panels include, but are not limited to the following: Prometheus® IBD Serology 7
This policy is based on an evidence review that was recently performed on October 17, 2019.
Summary of Evidence
At present, no single marker with qualities that are satisfactory for the diagnosis and treatment of IBD has been identified, although panels of some antibodies are being evaluated with keen interest. The discovery of novel IBD-specific and sensitive markers is anticipated. Such markers could minimize the use of endoscopic and radiologic examinations and could enable clinicians to implement individualized treatment plans designed to improve the long-term prognosis of patients with IBD.
A number of studies have examined the association between the serologic markers ASCA and ANCA and inflammatory bowel disease. Systematic reviews have found relatively low sensitivity and moderately high specificity. Moreover, the clinical utility of these assays has not been demonstrated. No studies demonstrated the use of these markers in lieu of a standard workup for IBD. A number of authors claim that these markers can be used to avoid invasive testing, but no studies demonstrated an actual decrease in the number of invasive tests through use of serum markers. Because of the suboptimal sensitivity levels of these serological tests, routine use of this screening is not supported. These technologies are investigational for the diagnosis and monitoring of inflammatory bowel disease given the insufficient evidence to evaluate the impact on net health outcome. Although the specificity of these tests are relatively high (82-100%), the sensitivity is low (32 -50%), which indicates that a negative result will not be clinically helpful. There is insufficient evidence in the peer-reviewed published medical literature to establish the effectiveness of this test on health outcomes when compared to established tests or technologies.
Practice Guidelines and Position Statements
American Gastroenterological Association
No guideline or position statement was found on The American Gastroenterological Association website regarding the use of serum antibodies for the diagnosis of inflammatory bowel disease.
American College of Gastroenterology
The American College of Gastroenterology practice guidelines for management of CD in adults stated that serological studies evaluating ASCA, ANCA, anti-CBir1, anti-OmpC are evolving to provide adjunctive support for the diagnosis of CD; however, they are not sensitive or specific enough to be recommended for use as a screening tools.
North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition
In 2012, the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition stated that commercially available serologic assays mail fail to detect CD in at least 30% of children with this disorder and may wrongly suggest a diagnosis of IBD that is not supported by subsequent and definitive (endoscopic study) testing. They further stated that it may be most prudent for primary care providers to avoid ordering these tests and instead pursue referral and more conclusive specialty testing.
The North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition and the Crohn’s and Colitis Foundation of America's consensus conference report on differentiating UC from CD in children and young adults stated that the clinical value of serology in patients with indeterminate colitis (IC) remains a topic of research, and further investigation should ascertain, among other areas, the role of surrogate laboratory markers (e.g., genetics, microbiology, and serology) in distinguishing these entities. A proposed algorithm to aid clinicians in differentiating UC from CD does not include serological testing.

This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.
This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.
The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.
As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage. The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:
1. The technology must have final approval from the appropriate government regulatory bodies;
2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;
3. The technology must improve the net health outcome;
4. The technology must be as beneficial as any established alternatives;
5. The improvement must be attainable outside the investigational setting.
Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:
1. In accordance with generally accepted standards of medical practice; and
2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and
3. Not primarily for the convenience of the patient, physician or other health care provider; and
4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
