Endometrial ablation is a potential alternative to hysterectomy for treatment of abnormal uterine bleeding. A variety of approaches are available; these are generally classified into hysteroscopic techniques (eg, Nd-YAG laser, electrosurgical rollerball) and nonhysteroscopic techniques (eg, cryosurgical, radiofrequency ablation).
Ablation or destruction of the endometrium is used to treat abnormal uterine bleeding in women who have failed standard therapy. It is considered a less invasive alternative to hysterectomy; however, as with hysterectomy, the procedure is not recommended for women who want to preserve fertility.
Multiple energy sources have been used. These include: neodymium-yttrium aluminum garnet (Nd-YAG) laser, a resecting loop using electric current, electric rollerball, and thermal ablation devices. Endometrial ablation is typically preceded by hormonal treatment to thin the endometrium.
Techniques for endometrial ablation are generally divided into two categories: those that do and do not require hysteroscopic procedures. (Other terminology for these categories of techniques include first-generation versus second-generation procedures and resectoscopic versus nonresectoscopic endometrial ablation methods). Hysteroscopic techniques were developed first; the initial technique was photovaporization of the endometrium using an ND-YAG laser, and this was followed by electrosurgical ablation using an electrical rollerball or electrical wire loop. (The latter technique is also known as transcervical resection of the endometrium). Hydrothermal ablation also involves hysteroscopy. Hysteroscopic techniques require skilled surgeons and, due to the requirement for cervical dilation, use of general or regional anesthesia. In addition, the need for the instillation of hypotonic distension media creates a risk of pulmonary edema and hyponatremia such that very accurate monitoring of fluids is required.
Non-hysteroscopic techniques can be performed without general anesthesia and do not involve use of a fluid distention medium. Techniques include thermal fluid-filled balloon, cryosurgical endometrial ablation, instillation of heated saline, and radiofrequency ablation.
There are concerns about maternal and fetal morbidity and mortality associated with pregnancy after endometrial ablation. Thus, U.S. Food and Drug Administration (FDA) approval of endometrial ablation devices includes only women for whom childbearing is complete.
Endometrial devices have been approved by the U.S. Food and Drug Administration through the premarket approval process for use in premenopausal women with abnormal uterine bleeding due to benign causes in whom childbearing is complete. These devices include, but may not be limited to, laser therapy, electrical wire loop, rollerball using electric current, and thermal ablation using a liquid-filled balloon, microwave, electrode array, or a cryosurgical device. Examples of devices for endometrial ablation are:
FDA Product Code: HHR.
POLICYEndometrial ablation, with or without hysteroscopic guidance, using an FDA-approved device may be considered medically necessary in women with abnormal uterine bleeding who are not candidates for, or who are unresponsive to, hormone therapy and would otherwise be considered candidates for hysterectomy.
Note: Intrauterine ablation or resection of the endometrium should not be confused with laparoscopic laser ablation of intraperitoneal endometriosis. This policy does not address laparoscopic intraperitoneal ablation.
Contradictions for intrauterine ablation or resection of the endometrium include:
Endometrial ablation is considered investigational for all other indications.
The coverage guidelines outlined in the Medical Policy Manual should not be used in lieu of the Member's specific benefit plan language.
Microwave ablation, thermal ablation and cryoablation may be performed in an office setting.
Other contraindications for microwave ablation include myometrial thickness less than 10 mm, and uterine sounding length less than 6 cm.
In February 2013, FDA downgraded its contraindication of NovaSure for women with Essure® contraceptive microinserts to a warning. The warning states that a health hazard may exist when a NovaSure procedure is performed in women with improperly positioned Essure® microinserts. To verify proper placement, a report of the Essure Confirmation Test should be obtained prior to performing the NovaSure procedure. The labeling change also includes the requirement for a post-approval study.
Medically Necessary is defined as those services, treatments, procedures, equipment, drugs, devices, items or supplies furnished by a covered Provider that are required to identify or treat a Member's illness, injury or Nervous/Mental Conditions, and which Company determines are covered under this Benefit Plan based on the criteria as follows in A through D:
A. consistent with the symptoms or diagnosis and treatment of the Member's condition, illness, or injury; and
B. appropriate with regard to standards of good medical practice; and
C. not solely for the convenience of the Member, his or her Provider; and
D. the most appropriate supply or level of care which can safely be provided to Member. When applied to the care of an Inpatient, it further means that services for the Member's medical symptoms or conditions require that the services cannot be safely provided to the Member as an Outpatient.
For the definition of Medically Necessary, “standards of good medical practice” means standards that are based on credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, and physician specialty society recommendations, and the views of medical practitioners practicing in relevant clinical areas and any other relevant factors. BCBSMS makes no payment for services, treatments, procedures, equipment, drugs, devices, items or supplies which are not documented to be Medically Necessary. The fact that a Physician or other Provider has prescribed, ordered, recommended, or approved a service or supply does not in itself, make it Medically Necessary.
Investigative is defined as the use of any treatment procedure, facility, equipment, drug, device, or supply not yet recognized as a generally accepted standard of good medical practice for the treatment of the condition being treated and; therefore, is not considered medically necessary. For the definition of Investigative, “generally accepted standards of medical practice” means standards that are based on credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, and physician specialty society recommendations, and the views of medical practitioners practicing in relevant clinical areas and any other relevant factors. In order for equipment, devices, drugs or supplies [i.e, technologies], to be considered not investigative, the technology must have final approval from the appropriate governmental bodies, and scientific evidence must permit conclusions concerning the effect of the technology on health outcomes, and the technology must improve the net health outcome, and the technology must be as beneficial as any established alternative and the improvement must be attainable outside the testing/investigational setting.
