Question: Answer: ABN: Medicare coverage rules for sterilization are as follows: Payment may be made only where sterilization is a necessary part of the treatment of an illness or injury, e.g., removal of a uterus because of a tumor or removal of diseased ovaries. Sterilization of a mentally retarded beneficiary is covered if it is a necessary part of the treatment of an illness or injury, (bilateral oophorectomy), or bilateral orchidectomy in a case of cancer of the prostate. The contractor denies claims when the pathological evidence of the necessity to perform any such procedures to treat an illness or injury is absent; and Monitor such surgeries closely and obtain the information needed to determine whether in fact the surgery was performed as a means of treating an illness or injury or only to achieve sterilization. A sterilization that is performed because a physician believes another pregnancy would endanger the overall general health of the woman is not considered to be reasonable and necessary for the diagnosis or treatment of illness or injury within the meaning of §1862(a)(1) of the Act. The same conclusion would apply where the sterilization is performed only as a measure to prevent the possible development of, or effect on, a mental condition should the individual become pregnant; and sterilization of a mentally retarded person where the purpose is to prevent conception, rather than the treatment of an illness or injury.
