CPT code 0083U is a Proprietary Laboratory Analyses (PLA) code assigned to the Onco4D™ test from Animated Dynamics, Inc., a tissue-based functional chemosensitivity assay that uses motility contrast tomography on fresh or frozen tumor specimens to predict cancer sensitivity or resistance to chemotherapy agents. PLA codes identify single-vendor laboratory tests and are increasingly important as precision oncology expands because they signal unique, manufacturer-specific diagnostics that lack direct generic equivalents. Nationally, such PLA codes affect coverage discussions, prior authorization workflows, and lab billing practices across commercial and public payers.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of payer coverage considerations, common billing patterns, and the clinical context in which the test is used. The publication highlights benchmarks for utilization and reimbursement where available, summarizes relevant policy and coding considerations tied to PLA status, and outlines the clinical utility—how motility contrast tomography informs chemotherapy selection. Data not provided in the input (such as specific coverage policies, reimbursement rates, and associated ICD-10 codes) are noted as unavailable. The piece is intended for laboratory billing managers, policy analysts, and oncology care teams seeking a national summary of CPT code 0083U and its practical implications for billing and clinical decision workflows.
