Where the denial was overturned

Nature of Statutory Criteria/Case Summary: The patient is a female who has been diagnosed with bilateral macromastia. The provider noted the patient had undergone previous breast surgeries, including breast augmentation and mastopexy. The patient has developed breast enlargement and ptosis with time, and a breast reduction was requested due to her breasts being large, heavy, and pendulous. Physical examination findings included bilateral pseudoptosis in dense fibroglandular breasts. The patient reported the size and weight of her breasts were pulling on her back, neck, and shoulders. Photographs of the patient show breast asymmetry, with the right breast larger than the left. Marked pseudoptosis is present, with almost all the breast volume below the level of the nipple. Shoulder grooving is present. The patient underwent bilateral reduction mammoplasty.

Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
The patient is a 15-year-old male with gynecomastia. According to the record he is not having pain or other physiologic problems related to his breast enlargement. He is said to suffer from low self-esteem, but there is no record of psychological counseling or psychotherapy included for review. The patient’s parent has requested authorization for bilateral reduction mammoplasty. The request was denied by the Health Plan based upon a determination that the procedure is not medically necessary.The record indicates the patient is obese, and obesity is a well-recognized cause of pubertal gynecomastia.
Medical Necessity · 2006 · IMR MN06-5998
A 53-year-old female enrollee has requested a bilateral reduction mammoplasty for the treatment of her macromastia. Findings: The physician reviewer found that the submitted clinical notes do not contain findings of intertrigo. While the patient’s primary care physician makes reference to chronic shoulder, back and neck pain, treatment notes documenting the chronicity of these complaints have not been provided. The low back complaints are not attributable to breast hypertrophy, though the upper back pain can be causally related to large breasts or other intrinsic cervical or thoracic etiology, the source of which has not been adequately documented in the supplied records. All told, there is inadequate evidence that the proposed mammoplasty is clinically indicated for this patient.
