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. | 13 | 38.5% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 3 | 33.3% |

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 reimbursement and prospective authorization and coverage for residential treatment center (RTC) services (ASAM 3.1). Per the American Society of Addiction Medicine (ASAM) criteria, this patient meet Level 3.1 criteria for RTC services. ASAM criteria focuses on six dimensions to determine the appropriate level of care, which includes: (1) intoxication and withdrawal potential; (2) biomedical conditions; (3) emotional, behavioral and cognitive conditions; (4) readiness to change; (5) relapse, continued use, or continued problem potential; and (6) recovery environment. For dimension 1, the patient underwent detoxification and has not demonstrated any symptoms of withdrawal while in residential care.

Where the denial was upheld
Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: The patient is a female with diagnoses of severe opioid use disorder, other severe stimulant dependence, bipolar II disorder, and generalized anxiety disorder.

She reported relapse after these admissions. The patient was admitted on for detoxification with a plan to discharge her to the RTC program. She was medically cleared from detoxification. Physician progress notes indicate that the patient was calm and cooperative with clear and coherent speech. Her mood and her affect were euthymic. Her thoughts were goal oriented. She denied current suicidal and homicidal ideation. She reported previous thoughts of suicide with a plan to overdose in 2015.
Nature of Statutory Criteria/Case Summary: The parent of an enrollee has requested authorization and coverage for the intensive outpatient program services provided from the end of October of 2018, going forward. The Health Plan has denied this request indicating that the requested services are not medically necessary for treatment of the enrollee’s intermittent explosive disorder and bipolar II disorder.At issue in this case is whether the intensive outpatient program services provided from the end of October of 2018, going forward are medically necessary for treatment of the enrollee’s behavioral health condition.In cases such as this, an evidence based instrument such as the CALOCUS (Child and Adolescent Level of Care Utilization System) is indispensable for determining necessary level of care for children, to insure their level of care meets their individual needs at the least restri…
