Medical Policy: 02.01.04 
Original Effective Date: July 2001 
Reviewed: September 2014 
Revised: September 2014 


Benefit Application
Benefit determinations are based on the applicable contract language in effect at the time the services were rendered. Exclusions, limitations or exceptions may apply. Benefits may vary based on contract, and individual member benefits must be verified. Wellmark determines medical necessity only if the benefit exists and no contract exclusions are applicable. This medical policy may not apply to FEP. Benefits are determined by the Federal Employee Program.

This Medical Policy document describes the status of medical technology at the time the document was developed. Since that time, new technology may have emerged or new medical literature may have been published. This Medical Policy will be reviewed regularly and be updated as scientific and medical literature becomes available.


Description: 

Anorectal biofeedback is a treatment program that utilizes neuromuscular conditioning techniques to treat patients with fecal incontinence or chronic constipation that is associated with dyssynergic defecation.  Dyssynergic defecation, also known as anismus or pelvic floor dyssynergia, is characterized by failure of the abdominal, rectal, pelvic floor and anal sphincter muscles to coordinate and complete the act of defecation.  It is characterized by impaired propulsion of stool from the rectum, paradoxical anal contraction, or inadequate anal relaxation, or a combination of these mechanisms.

 

Appropriate candidates for receiving biofeedback therapy (neuromuscular training) are:

A. Patients who have a diagnosis of dyssynergic defecation.
B. Patients who have tried standard approaches for treatment of constipation including OTC laxatives, and failed these approaches for at least three months.
C. They must fulfill the symptomatic criteria for dyssynergic defecation.
D. They must fulfill the objective physiologic criteria for dyssynergic defecation described.

Diagnostic criteria for dyssynegric defecation: Patients must fulfill both criteria A and criteria B as defined below.

A. Patients must fulfill the symptomatic criteria for functional constipation as defined by ROME III criteria, which states that patients must report two or more of the following symptoms for at least 3 months with a symptom onset of at least 6 months duration.

1. Straining during at least 25% defecations.
2. Lumpy or hard stools with at least 25% defecations.
3. Sensation of incomplete evacuation following at least 25% decations.
4. Sensation of anorectal obstruction or blockage during at least 25% defecations.
5. Manual maneuvers to facilitate bowel movements with at least 25% defecations (digital evacuation, etc.)
6. Fewer than three bowel movements per week.

B. Constipated patients must fulfill two or more of the following objective physiological criteria during repeated attempts to defecate.

1. Dyssnergic pattern of defecation that comprises of either inappropriate contraction of the pelvic floor muscles (anal sphincter of puborectalis) or less than 20% relaxation of basal resting sphincter pressure.
2. Inadequate propulsive forces as assessed by manometry or imaging or EMG.
3. Inability to expel a 50 ml water-filled balloon or a stool-like device such as fecom within 1 minute.
4. A prolonged colonic transit time (more than 6 markers on a plain abdominal radiograph taken 120 hours after ingestion of one Stizmarks® capsule containing 24 radio opaque markers or using other technology such as nuclear scintigraphy or SmartPill® colonic transit study.)
5. Inability to expel barium paste or greater than 50% retention of barium past during defecography.

Anorectal biofeedback is an instrument-based learning technique wherein an instrument such as a manometry probe is placed inside the body to provide visual or auditory information to the patient regarding their anorectal muscle function.

 

Biofeedback therapy is a process based on operant conditioning techniques and the governing principle is that any behavior - whether complex or simple - is reinforced. It can be performed either by placing a manometry probe with multiple micro-transducers and a balloon or a water perfused probe with multiple side holes into the rectum. This in turn provides either visual or auditory display of muscle activity.  The patient and the therapist use this information to learn how to control and improve anorectal function.  In addition to office biofeedback training, portable units are also available to facilitate home training.

 

The treatment consists of advice and instruction during an initial visit regarding bowel habits, exercise, laxatives, dietary fiber and fluid intake and timed toilet training.  In addition to receiving the instruction, subjects have an initial training session by a specialist generally followed by biweekly, 1-hour biofeedback sessions, up to a maximum of 6 therapy sessions during a period of 3 months during the active phase.  A follow up phase typically consists of reinforcement at 6 weeks and 3, 6, and 12 months.

 

Currently the study of biofeedback use in children with dyssynergic type defecation is lacking. There is a lack of clinical trials or randomized studies involving biofeedback in the use of children.

 

In 2013, the American Gastroenterological Association updated their position statement on constipation. The following statement on biofeedback was included: “Pelvic floor retraining by biofeedback therapy rather than laxatives is recommended for defecatory disorders (Strong Recommendation, High-Quality Evidence).”

 

In May 2010, the National Institute for Clinical Excellence issued a guideline on constipation in children and young people. The guideline states that biofeedback should not be used for ongoing treatment. In June 2007, they issued a guideline on fecal incontinence in adults which states the following regarding biofeedback: “The evidence we found did not show biofeedback to be more effective than standard care, exercises alone, or other conservative therapies. The limited number of studies and the small number of participants in each group of the studies make it difficult to come to any definitive conclusion about its effectiveness.”

Prior Approval: 

 

Not applicable

Policy: 

Anorectal biofeedback may be considered medically necessary for documented dyssynergic defecation in adults

The recommended treatment course for those with dyssynergic defecation is biofeedback sessions over 3 months. This is consistent with the protocol used in randomized trials showing benefit of biofeedback.

 

Anorectal biofeedback is considered investigational in children.

 

Anorectal biofeedback is considered investigational for fecal incontinence when the cause is not dyssynergic defecation.

 

Anorectal biofeedback is considered investigational for any condition not listed above including but not limited to: urinary incontinence, fecal incontinence or those patients with a diagnosis of irritable bowel syndrome.
