Coverage Determinations

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Investigational/Not Medically Necessary: Coma stimulation (also known as coma stimulation sessions, coma arousal therapy, multisensory stimulation programs and coma care) for brain injured individuals in a coma or vegetative state is considered investigational and not medically necessary because its effectiveness has not been established.

Applies to Commercial, Self-Funded, Medicare Advantage, MediSource, MediSource Connect, Child Health Plus and Essential Plan.

Independent Health considers coma stimulation (also described as coma stimulation sessions, coma arousal therapy, multisensory stimulation programs, or coma care) not medically necessary because its effectiveness has not been established. As such, the service is classified as investigational and is not a covered benefit across applicable lines of business.

Clinical Background

Coma is a profound or deep state of unconsciousness (also referred to as a persistent vegetative state) in which thinking abilities and awareness are lost while some noncognitive functions and sleep–wake patterns may remain. It can arise from a broad range of medical and neurologic conditions including traumatic brain injury, cerebrovascular disease, intoxication, infections, and seizures.

Coma stimulation programs use planned, controlled multisensory inputs (for example visual, auditory, tactile, gustatory and olfactory stimulation) with the goal of promoting arousal. However, the peer‑reviewed literature has not established the effectiveness of these interventions, which is the basis for the policy’s investigational stance.
