What the insurer actually argued

Denials fall into different categories, and they don’t succeed equally — so the reason on your letter changes how you should answer it.

Medical Necessity
The plan said the care wasn’t medically necessary. The most common fight, and the most winnable.

Experimental/Investigational
The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument.

What the reviewers wrote

Excerpts from the independent reviewers’ published findings — the actual reasoning, quoted, not summarised.

Where the denial was overturned

Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for bilateral mastectomy and liposuction procedure (CPT 19300 and 15877). Arya and colleagues state that, “True gynecomastia refers to enlarged glandular tissue rather than deposition of fat tissue. Enlargement of breast due to deposition of fat in the breast area is known as pseudogynecomastia.” The authors noted that, “The aims of surgery are: (a) To eliminate painful breast tissue. (b) To restore the patient’s chest to acceptable cosmetic shape. The most commonly used technique is subcutaneous mastectomy that involves direct resection of the glandular tissue using a peri-areolar or trans-areolar approach, with or without liposuction.” Per the American Society of Plastic Surgeons (ASPS), the requested bilateral mastectomy and liposuction procedure are not medically necessary.

Nature of Statutory Criteria/Case Summary: The patient requested reimbursement for a mastectomy. Gynecomastia is the presence of an abnormal proliferation of breast tissue that accounts for up to 65% of male breast disorders. Gynecomastia has a broad range of causes that are classified as either physiological or pathological, although in many cases, no specific cause can be found. In a study, the authors reported that guidelines for gynecomastia state that, “gynecomastia (GM) is a benign proliferation of the glandular tissue of the breast in men. It is a frequent condition with a reported prevalence of 32 to 65%, depending on the age and the criteria used for definition.

Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for bilateral mastectomy. According to the American Society of Plastic Surgeons (ASPS), “gynecomastia is defined as the presence of an abnormal proliferation of breast tissue in males.” However, the ASPS noted that, “in pseudogynecomastia, the breast enlargement is secondary to fat accumulation; and both glandular and fat tissue are present in mixed gynecomastia. Gynecomastia is different from pseudogynecomastia, which is an increase in subareolar fat often related to obesity.

In true gynecomastia, the breast enlargement is due to glandular breast tissue while in pseudogynecomastia, the breast enlargement is secondary to fat accumulation. Both glandular and fat tissue are present in mixed gynecomastia. Gynecomastia is to be differentiated from pseudogynecomastia, an increase in subareolar fat often related to obesity. True gynecomastia has a palpable firm disc of tissue under the nipple areolar complex.

How to use this in your appeal

These outcomes describe eligible cases completed through California DMHC’s Independent Medical Review program. They do not estimate the chance that an internal appeal, an external review in another jurisdiction, or your individual case will succeed. Use the record to identify evidence patterns involving gynecomastia, then check the rights and deadlines that apply to your plan.
