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 given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 90 | 37.8% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 10 | 50% |

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 requested authorization and coverage for a colonoscopy and monitored anesthesia care. The submitted documentation supports the medical necessity of the requested colonoscopy for evaluation of this patient. A review of the record reflects that the patient has been diagnosed with ulcerative colitis. Clinical guidelines from the American College of Gastroenterology (ACG) indicate that colonoscopy for dysplasia screening is recommended every one to three years in patients that have been diagnosed with ulcerative colitis for over eight years. Other studies have reported longstanding recommendations for a colonoscopy every one to two years in those patients. In this case, the patient has a history of active ulcerative colitis. Further, a review of the record establishes that the patient has not undergone a colonoscopy for a few years.
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for monitored anesthesia care for management of the enrollee’s pain during her colonoscopy. Findings: The physician reviewer found that according to the American Society of Anesthesiologists (ASA), an essential component of MAC anesthesia is the “anesthesia assessment and management of a patient’s actual or anticipated physiological derangements or medical problems that may occur during a diagnostic or therapeutic procedure.” Also, “While Monitored Anesthesia Care may include the administration of sedatives and/or analgesics often used for Moderate Sedation, the provider of MAC must be prepared and qualified to convert to general anesthesia when necessary.
Where the denial was upheld
Worth reading too — these show what an appeal has to overcome.
The patient is a 56-year-old male who has requested authorization for a virtual colonoscopy for colon cancer screening. The patient has been on Coumadin for recurrent atrial fibrillation and he is concerned that discontinuing his anticoagulation therapy prior to a standard colonoscopy will put him at risk. Therefore, he is seeking approval of a virtual colonoscopy. The Health Plan has denied his request on the basis that a virtual colonoscopy is not medically necessary.Virtual colonoscopy represents a noninvasive test for the examination of the colonic lumen that involves the generation of both two-dimensional and three-dimensional views of the colon and rectum using data derived from computed tomography. This imaging modality has been explored as an alternative to conventional endoscopic colonoscopy, particularly as an alternative screening tool for colorectal cancer.
The patient is a 55-year-old male who was referred by his provider for a screening colonoscopy in February 2005. The patient has no prior history of a screening colonoscopy and no prior history of a failed attempt or unsuccessful colonoscopy. The patient underwent a CT colonography (virtual colonoscopy) instead of a conventional optical colonoscopy, which revealed a normal appearing colon and two left renal calculi. At issue is whether the virtual colonoscopy was medically necessary for evaluation of the patient’s medical condition.Virtual colonoscopy represents a noninvasive test for the examination of the colonic lumen that involves the generation of both two-dimensional and three-dimensional views of the colon and rectum using data derived from computed tomography.
