Care levels at TriStar Centennial Parthenon Pavilion

The facility offers a continuum of care across multiple levels — Inpatient, PHP, MAT, Dual Dx — which means it can, in principle, hold a patient across the arc of a typical treatment episode. The practical question is whether it is genuinely strong at each level, or whether one level is the core business and the others are secondary. Operational prerequisite for admission: documented clinical assessment establishing medical necessity for the specific level of care TriStar Centennial Parthenon Pavilion provides. The ASAM Criteria 4e framework is the benchmark standard for this assessment and is referenced in most major payer medical-necessity documents.

Insurance and payment

TriStar Centennial Parthenon Pavilion accepts both Medicaid and commercial insurance, which is the broadest payer profile and typically correlates with programs that operate at scale across the economic spectrum. The facility also accepts TRICARE or military benefits. Benefit verification should be obtained in writing prior to admission and should document: network contract status for the specific insurance product, prior authorization requirements and approved day-count, applicable cost-sharing structure, and out-of-network secondary coverage (where applicable). Proceeding on verbal VOB creates material risk of post-admission benefit dispute.

Specialty programming

The facility's documented specialty programming includes: Seniors or older adults, Clients with co-occurring mental and substance use disorders, Clients who have experienced trauma. Evaluation of specialty-program alignment requires documented review of clinical team credentials, specialty-specific programming hours, and integrated assessment protocols. Specialty designation without documented clinical infrastructure is a recognized marketing pattern in the sector.
