The use of periurethral bulking agents approved by the U.S. Food and Drug Administration (e.g., collagen, Durasphere, Coaptite, Macroplastique implantation) to treat patients with stress urinary incontinence due to intrinsic sphincter deficiency is considered medically necessary for the following types of patients who have shown no improvement in their incontinence for at least 12 months:

• Male or female patients with congenital sphincter weakness, secondary to conditions such as myelomeningocele or epispadias;
• Male or female patients with acquired sphincter weakness secondary to spinal cord lesions;
• Male patients following trauma, including prostatectomy and/or radiation; and
• Female patients without urethral hypermobility and with abdominal leak point pressures (ALPP) of less than 100 cm H2O.

Patients whose incontinence does not improve with five injection procedures (five separate treatment sessions) are considered treatment failures. Therefore, no further treatment of urinary incontinence with a periurethral bulking agent is covered.

In addition, patients who have a reoccurrence of incontinence following successful treatment with FDA approved periurethral bulking agent implants in the past (e.g., 6-12 months previously) may benefit from additional treatment sessions. Coverage of additional sessions may be allowed but must be supported by medical record documentation.

Prior to collagen implant therapy, a skin test for collagen sensitivity (95028) should be administered and the patient should be evaluated over a four-week period prior to the implant. Payment may also be made for the collagen skin test material (Q3031) when used in conjunction with these services.

Description

Stress urinary incontinence can result from intrinsic sphincter deficiency (ISD). ISD is a cause of stress urinary incontinence in which the urethral sphincter is unable to contract and generate sufficient resistance in the bladder, especially during stress maneuvers (e.g., coughing, bending, and lifting). In order to treat this condition, an endoscopic injection of implant material (51715) can be performed.

Periurethral bulking agents (L8603, L8604, L8606), (e.g., cross-linked collagen implant, carbon-coated beads, e.g., Durasphere, spherical particles of calcium hydroxylapatite, e.g., Coaptite, or polydimethylsiloxane, e.g., Macroplastique) are substances used in the treatment of stress urinary incontinence. The implant is injected into the submucosal tissues of the urethra and/or the bladder neck and into the tissues adjacent to the urethra either suburethrally through a cystoscope with a spinal needle inserted percutaneously, or transvaginally with cystoscopic control. This procedure may be performed over the course of two to three visits to a physician.
