A Colorado father is suing Cigna over denied mental health benefits for his teenage son.
The complaint, filed September 22 in US District Court for the District of Colorado, alleges Cigna Health and Life Insurance Company refused to cover residential treatment the boy's doctors said he needed - and that the insurer's reasons for saying no kept changing along the way.
The father brings the case under ERISA - the federal law governing employer-sponsored benefit plans - on behalf of his minor child. He was enrolled in a health plan sponsored by his employer, Musarubra US, LLC. Cigna administered claims under the plan, while a vendor called Evernorth Behavioral Health handled mental health claims on Cigna's behalf.
The teenager had been diagnosed with multiple conditions, including ADHD, persistent depressive disorder, generalized anxiety disorder with social anxiety features, and several substance use disorders. According to the complaint, he had a documented history of self-harm, and his substance use had escalated from nicotine and marijuana to alcohol, cocaine, and other substances over time.
Roughly a week before being admitted to residential treatment, the teenager overdosed on Xanax and alcohol, the filing states. His treatment providers recommended long-term residential care as medically necessary.
The boy was first admitted to Elements Wilderness Program, an intermediate residential behavioral health program licensed in Utah. The complaint alleges Cigna declined to process the claims, flagging the absence of a prior authorization on file and requesting more information from the provider. The father appealed. According to the complaint, Cigna failed to make a timely claim determination and then denied the claims on a different basis entirely - that the treatment was "experimental, investigational, and/or unproven." When the father appealed again, the filing says Cigna rejected that appeal as untimely.
That is three different responses to the same set of claims.
After Elements, the teenager moved to Crossroads Academy, a licensed Utah residential treatment center specializing in adolescent boys with co-occurring substance use and mental health disorders. This time, Cigna denied coverage on medical necessity grounds, relying on a set of clinical benchmarks called the MCG Behavioral Health Guidelines - third-party criteria insurers use to assess whether a particular level of care is warranted. The complaint alleges those guidelines are "unfair and biased against approving claims for residential treatment" and do not reflect reasonable standards in the medical community. When the father requested an independent external review, the filing states Cigna failed to acknowledge, assign, or decide the review within the required timeframe.
A central thread in the complaint is the Federal Mental Health Parity and Addictions Equity Act - a federal law that requires group health plans to cover mental health and substance use treatment on the same terms as physical health benefits. The father alleges Cigna violated that requirement by applying acute-care criteria - essentially requiring evidence of acute symptoms showing risk of serious harm - to evaluate what was a step-down residential placement, not an emergency admission. The plan's own terms covered residential treatment for members needing 24-hour care who did not require acute inpatient admission, the complaint states. Demanding acute-level symptoms for a lower-intensity setting, the father argues, set a higher bar for mental health coverage than for comparable medical and surgical benefits.
The complaint pursues two claims. The first seeks reimbursement for what the father says he paid out of pocket for treatment at both facilities, plus prejudgment interest and attorneys' fees. The second alleges breach of fiduciary duty - in plain terms, a claim that Cigna failed in its legal obligation to act in the plan members' best interests. The father argues Cigna shifted its denial rationale at each stage of the appeals process, failed to engage in the "meaningful dialogue" ERISA requires, and interpreted the plan in a way that minimized benefits. He is also asking the court to order Cigna to stop using acute-level criteria for step-down mental health placements and to hand over the specific guidelines it relied on when denying future claims.
For claims and compliance teams, the case is a practical reminder that procedural missteps - shifting rationales, blown deadlines, criteria that do not match the level of care under review - can become the lawsuit itself, regardless of whether the underlying denial was defensible.
The allegations in the complaint have not been tested in court, and no judicial determination has been made on any of the claims.
