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.
Reason givenDecisionsOverturned
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: A patient has requested authorization and coverage for Zepbound. The submitted documentation supports the medical necessity of the requested medication. The U.S. Food and Drug Administration (FDA) approves the use of Zepbound (tirzepatide) injection for chronic weight management in adults with obesity, defined as a BMI of 30 kg/m² or greater, or who are overweight, defined as a BMI of 27 kg/m² or greater, with at least one weight-related condition such as high blood pressure, type 2 diabetes, or high cholesterol for use in addition to a reduced calorie diet and increased physical activity. Anti-obesity medications, when combined with lifestyle intervention, produce larger weight losses than behavioral treatment alone.

Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested reimbursement and prospective authorization and coverage for Zepbound. The submitted documentation supports the medical necessity of the requested medication. The U.S. Food and Drug Administration (FDA) approves the use of Zepbound (tirzepatide) injection for chronic weight management in adults with obesity, defined as a BMI of 30 kg/m² or greater, or who are overweight, defined as a body mass index (BMI) of 27 kg/m² or greater, with at least one weight-related condition such as high blood pressure, type 2 diabetes, or high cholesterol for use in addition to a reduced calorie diet and increased physical activity. Anti-obesity medications, when combined with lifestyle intervention, produce larger weight losses than behavioral treatment alone.

Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
Physician 1: The patient is a 50-year-old female with a history of hyperlipidemia and low levels of HDL treated with gemfibrozil and Pravachol. She had a baseline EBCT in 2003 and a second imaging study in June 2005. The Health Plan denied the patient’s request for reimbursement of the follow-up study based upon their determination that EBCT is considered experimental/ investigational for evaluation of coronary artery disease. In adults at low risk for coronary heart disease (CHD) events, the United States Preventive Services Task Force (USPSTF) now recommends against routine screening for either the presence of severe coronary artery stenosis (CAS) or the prediction of CHD events with resting electrocardiography (ECG), exercise treadmill test (ETT), or electron-beam computed tomography (EBCT) scanning for coronary calcium.
Experimental/Investigational · 2005 · IMR EI05-5058
Nature of Statutory Criteria/Case Summary: The patient presented for a cardiovascular risk assessment evaluation secondary to a diagnosis of dyslipidemia. The most recent cholesterol level is 209, with low density lipoprotein (LDL) of 114 and high density lipoprotein (HDL) of 78. The patient denied associated symptoms, including decreased activity or exercise tolerance, shortness of breath, swelling, or chest pain. There was no documented history of hypertension or diabetes. The patient was educated and following a low carbohydrate, low fat diet, and exercising five to six times per week. She was referred for advanced lipoprotein testing including lipid particle number and sizing for further risk stratification.

Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California external-review outcomes. Other state and federal programs have different eligibility rules, processes, and current availability; the rates here do not transfer to those programs or predict an individual result. Excerpts are quoted verbatim from the public record and describe this condition generally, not any individual case.

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 dyslipidemia, then check the rights and deadlines that apply to your plan.
