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. | 1,046 | 41.9% |
Urgent Care Expedited reviews, decided in days rather than weeks. | 11 | 9.1% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 4 | 25% |

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 enrollee is requesting reimbursement for residential treatment center services. The enrollee has major depressive disorder, generalized anxiety disorder, substance abuse, attention deficit hyperactivity disorder (ADHD), and non-verbal learning disorder and received outdoor behavioral health treatment. He had been in treatment at a different facility, but his therapist noted he did not make progress and needed a higher level of care. The recommendation was for a high level of activity and involvement in a variety of social, recreational and outdoor activities.
A review of the medical records from the inpatient hospitalization and the residential treatment facility reveals that the patient is a 19-year-old male who entered an inpatient level of care in March 2006 after being transferred from a mental health clinic near where he attends college. The patient was in an altered state of consciousness and felt to be a danger to himself on admission to the facility. He was admitted on a 5150 hold and remained at this level of care until April 2006. The description of his mental status on admission was that he was “giggly and disoriented.” Prior to admission he became assaultive and needed to be given IM medications to control his behavior. The history prior to admission was that the patient experimented with marijuana and other drugs while at college. He reports using LSD, cocaine, Ecstasy and alcohol.
Where the denial was upheld
Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: The parent of an enrollee has requested reimbursement and authorization and coverage for residential treatment center services. The progress notes indicate that during the period he was at the residential treatment center, the patient showed cooperative behavior and treatment progress. At times, he was unwilling to wake up when prompted, but overall, his behavior was cooperative. He was noted to play games with staff and peers and have good relationships in the treatment center. The notes do not indicate that he had any significant issues with peers. He followed all treatment programming as he was instructed. The progress notes indicate that he was open and honest in regards to his feelings about his mood and other problematic issues. He denied any past substance use.
Nature of Statutory Criteria/Case Summary: The parent of a transgender female-to-male patient has requested authorization and coverage for residential treatment center services going forward. The Health Plan has denied this request indicating that the requested services are not medically necessary for treatment of the enrollee’s major depressive disorder; generalized anxiety disorder; feeding or eating disorder; and post-traumatic stress disorder.At issue in this case is whether the requested residential treatment center services going forward are medically necessary for treatment of the patient’s behavioral health condition.This appeal concerns denial of stay at the residential treatment center (RTC). During the disputed timeframe, the beneficiary showed cooperative behavior and treatment progress.
