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

Where the denial was overturned

The patient is a 50-year-old male with a 35-year history of alcohol abuse. Prior to his admission to substance abuse treatment the patient was drinking on the order of two to three bottles of wine per sitting, typically drinking three to four times per week, in addition to periodic use of marijuana. The latter involved one joint per day, last on 6/1/04, and the submitted notes indicate the patient last drank two bottles of wine, two beers, and three cocktails on 6/22/04 prior to entering residential treatment on 6/25/04. The patient noted a very fractious relationship with his wife; a divorce was soon to be finalized due to his extramarital affairs. In addition, the patient had a history of yelling at his wife and their two children quite a bit and pushed his wife on occasion.

Nature of Statutory Criteria/Case Summary: A patient has requested reimbursement for the residential substance abuse treatment services provided from 4/25/18 through 5/18/18. The Health Plan has denied this request indicating that the services at issue were not medically necessary for treatment of the patient’s behavioral health conditions. The submitted documentation supports the medical necessity of the services at issue. The American Psychiatric Association treatment guidelines for substance use disorders recommends that residential treatment is indicated for patients who do not meet the clinical criteria for hospitalization but whose lives and social interactions have come to focus predominantly on substance use, lack sufficient social and vocational skills, and drug-free social supports to maintain abstinence in an outpatient setting.

The progress notes did not document psychosis, paranoia or mania symptoms during the residential treatment stay. He had depression and anxiety that were both noted to be mild. The records did not indicate severe symptoms that would require intensive psychiatric care.
