Inpatient Intestinal Rehabilitation Therapy
Policy Number: MP-152
Latest Review Date: December 2023
Category: Medical
POLICY:
An inpatient program of intestinal rehabilitation, consisting of metabolic evaluation, patient counseling and education, nutritional counseling, physical therapy, and treatment with growth hormone and glutamine is considered investigational for individuals with short bowel syndrome who are dependent on total parenteral nutrition.
DESCRIPTION OF PROCEDURE OR SERVICE:
Short bowel syndrome (SBS) is a malabsorption syndrome that can occur after extensive small intestinal resection, significant damage to the small intestine, or poor motility. Individuals with SBS are not able to absorb enough vitamins, minerals, fats, calories, or other nutrients from food. It is characterized by chronic diarrhea, dehydration, electrolyte abnormalities, and malnutrition as a result of severe maldigestion and malabsorption. Common causes of SBS in adults include resection due to Crohn’s disease, a catastrophic vascular event such as mesenteric arterial embolism or venous thrombosis, volvulus, trauma, or tumor. Most individuals are initially fed with total parenteral nutrition (TPN) to help prevent the development of malnutrition. Some individuals may be difficult to wean from TPN. This includes individuals with very short remaining small bowel segments (< 60 cm), loss of colon, loss of ileocecal valve, or small bowel strictures. This parenteral nutrition provides protein, calories, other macronutrients, and micronutrients until the bowel has had time to adapt.
After massive enterectomy, the intestine adapts to ensure more efficient absorption per unit length. There is slight lengthening, but also diameter and villus height increase, which increases the absorptive surface. This intestinal adaptation process continues for up to two years. The exact mechanisms are not known, but various factors have been shown to enhance adaptation, including growth hormone, glutamine, epidermal growth factor, certain peptides and interleukins, soluble fiber, short chain fatty acids, and pancreaticobiliary secretions. There has been a great deal of research interest in methods to increase intestinal adaptation as a nonsurgical alternative to intestinal transplantation. Specifically, the combination of the amino acid glutamine and human recombinant growth hormone (GH), in conjunction with a high carbohydrate, low fat diet, has been studied. Glutamine, administered either enterally or parenterally, and growth hormone, administered subcutaneously, is thought to have trophic affects on the bowel.
There are some inpatient programs specifically designed for individuals with short bowel syndrome who are dependent on TPN for their nutritional needs. The programs offer intensive counseling and tailored regimens of diet modification, glutamine, and growth hormone therapy to these individuals. The goal of these programs is to help individuals either eliminate or reduce the need for total parenteral nutrition.
In 1993, the Nutritional Restart Center (NRC) for intestinal rehabilitation was started in
KEY POINTS:
The early published data are almost exclusively derived from researchers working at the NRC near
Summary of Evidence
The evidence for inpatient intestinal rehabilitation consists of several industry sponsored and small studies. Study results indicate that this type of treatment is controversial and long term results are needed to determine the effect on net health outcomes.

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.
