Plus Therapeutics Announces New Category III CPT Code for Convection-Enhanced Delivery Used with REYOBIQ

Unlocks market access and growth potential of REYOBIQ therapy in recurrent glioblastoma and pediatric brain cancer by enabling adoption and utilization tracking

HOUSTON, Feb. 25, 2026 (GLOBE NEWSWIRE) -- Plus Therapeutics, Inc. (NASDAQ: PSTV) (the “Company”), a healthcare company developing and commercializing precision diagnostics and radiopharmaceuticals for central nervous system (CNS) cancers, today announced the American Medical Association’s (AMA) CPT

(Current Procedural Terminology) Editorial Panel approved a new Category III CPT code to track utilization of convection-enhanced delivery (CED) used in the administration of REYOBIQ for recurrent glioblastoma (rGBM) and pediatric brain cancer (PBC).  

“The approved Category III CPT code for convection-enhanced delivery of REYOBIQ in recurrent glioblastoma and pediatric brain cancer – the most prevalent malignant tumors of the brain and central nervous system – marks a major step in bringing market access for an innovative treatment targeting an aggressive and deadly disease resistant to conventional treatments. This milestone reflects the culmination of years of REYOBIQ development and represents an important advancement in our path to commercialization and reimbursement. With standardized REYOBIQ clinical use now tracked under the new CPT code, its utilization can be evaluated as a bridge to approval and broad adoption,” said Marc Hedrick MD, Plus Therapeutics President and CEO. “We remain focused on making strong clinical progress with REYOBIQ. We are on track to complete enrollment in our Phase 2 recurrent glioblastoma trial in 2026, followed by an end-of-Phase 2 meeting to align on pivotal trial design. In addition, we continue to expect first patient enrollment in our Phase 1 pediatric brain cancer trial in 2026.”

Category III CPT codes are established by the AMA’s CPT

Editorial Panel to describe emerging medical technologies and procedures and to support utilization tracking and data collection that may inform future coverage, reimbursement, and transition to permanent Category I CPT codes.   The approved Category III CPT code for CED procedures is:

• X566T, Stereotactic placement of infusion catheter(s), brain, for delivery of therapeutic agent(s), including computerized stereotactic planning and burr hole(s).

About REYOBIQ™ (rhenium Re186 obisbemeda)
REYOBIQ (rhenium Re186 obisbemeda) is a novel injectable radiotherapy specifically formulated to deliver direct targeted high dose radiation in CNS tumors in a safe, effective, and convenient manner to optimize patient outcomes. REYOBIQ has the potential to reduce off target risks and improve outcomes for CNS cancer patients, versus currently approved therapies, with a more targeted and potent radiation dose. Rhenium-186 is an ideal radioisotope for CNS therapeutic applications due to its short half-life, beta energy for destroying cancerous tissue, and gamma energy for real-time imaging. REYOBIQ is being evaluated for the treatment of recurrent glioblastoma, leptomeningeal metastases, and pediatric brain cancer in the ReSPECT-GBM, ReSPECT-LM, and ReSPECT-PBC clinical trials. ReSPECT-GBM is supported by an award from the National Cancer Institute (NCI), part of the U.S. National Institutes of Health (NIH), and ReSPECT-LM is funded by a three-year $17.6M grant by the Cancer Prevention & Research Institute of Texas (CPRIT). The Company’s ReSPECT-PBC clinical trial for pediatric brain cancer is supported by a $3 million grant from the U.S. Department of Defense’s Peer Reviewed Cancer Research Program.
